THE common herring is one of our most beautiful and
abundant fishes. It is taken throughout the year in vast quantities, thus
affording a plentiful supply of cheap and wholesome food to all classes,
whilst its capture and cure afford remunerative employment to a large body
of industrious people. It is greatly to be regretted, therefore, that
recent fluctuations in the quantity caught have given occasion for
well-grounded fears of an ultimate exhaustion of some of our largest
shoals, or at all events of so great a diminution of their producing power
as probably to render one or two of the best fisheries unproductive. This
is nothing new, however, in the history of the herring-fishery various
places can be pointed out, which, although now barren of herrings, were
formerly frequented by large shoals, that, from overfishing or other
causes, have been dispersed.
This supposed overfishing of the herring has resulted
chiefly from our ignorance of the natural history of that fish-ignorance
which has long prevailed, and which we are only now beginning to overcome.
Indeed, much as the subject has been discussed during the last ten years,
and great as the light is that has been thrown on the natural and economic
history of our fish, considering the elemental difficulty which stands in
the way of perfect observation, there are yet persons who insist upon
believing all the old theories and romances pertaining to the lives of sea
animals. We occasionally hear of the great sea-serpent ; the impression of
St. Peter's thumb is still to be seen on the haddock ; " Moby Dick," a Tom
Savers among fighting whales, still ranges through the squid fields
of the Pacific Ocean ; and I know an old fisherman who once borrowed a
comb from a polite mermaid !
Not very long ago, for instance, the old theory of the
migration of the herring to and from the Arctic Regions was gravely
revived in an unexpected quarter, as if that romance of fish-life was
still believed by modern naturalists to be the chief episode in the
natural history of Clupea harengus. The original migration
story-which was invented by Pennant, or rather was constructed by him from
the theories of fishermen-old as it is, is worthy of being briefly
recapitulated, as affording a good point of view for a consideration of
the natural and economic history of the herring as now ascertained : it
was to the effect that in the inaccessible seas of the high northern
latitudes herrings were found in overwhelming abundance, securing within
the icy Arctic Circle a bounteous feeding-ground, and at the same time a
quiet and safe retreat from their numerous enemies. At the proper season,
inspired by some commanding impulse, vast bodies of this fish gathered
themselves together into one great army, and in numbers far exceeding the
power of imagination to picture departed for the waters of Europe and
America. The particular division of this great heer, which was
destined annually to repopulate the British sets, and afford a plenteous
food-store for the people, was said to arrive at Iceland about March, and
to be of such amazing extent as to occupy a surface more than equal to the
dimensions of Great Britain and Ireland, but subdivided, by a happy
instinct, into battalions five or six miles in length and three or four in
breadth, each line or column being led, according to the ideas of
fishermen, by herrings (probably the Alice and Twaite shad)
of more than ordinary size and sagacity. These heaven-directed strangers
were next supposed to strike on the Shetland Islands, where they divided
of themselves, as we are told ; one division taking along the west side of
Britain, whilst the other took the east side, the result being an adequate
and well-divided supply of this fine fish in all our larger seas and
rivers, as the herrings penetrated into every bay, and filled all our
inland lochs from Wick to Yarmouth. Mr. Pennant was not contented with the
development of this myth, but evidently felt constrained to give Mat
to his invention by inditing a few moral remarks just by way of a
tag. "Were we," he says, " inclined to consider this migration of the
herring in a moral light, we might reflect with veneration and awe on the
mighty power which originally impressed on this useful body of His
creatures the instinct that directs and points out the course that blesses
and enriches these islands, which causes them at certain and invariable
times to quit the vast polar depths, and offer themselves to our expectant
fleets. This impression was given them that they might remove for the sake
of depositing their spawn in warmer seas, that would mature and vivify it
more assuredly than those of the frigid zone. It is not from defect of
food that they set themselves in motion, for they come to us full and fat,
and on their return are almost universally observed to be lean and
miserable."
Happily, the naturalists of the present day know a vast
deal more of the natural history of the herring than Mr. Pennant ever
knew, and on the authority of the most able inquirers it may be taken for
granted that the herring is a local and not a migratory fish. It has been
repeatedly demonstrated that the herring is a native of our immediate
seas, and can be caught all the year round on the coasts of the three
kingdoms. The fishing begins at the island of Lewis, in the Hebrides, in
the month of May, and goes on as the year advances, till in July it is
being prosecuted off the coast of Caithness ; while in autumn and winter
we find large supplies of herrings at Yarmouth ; and there is a winter
fishery in the Firth of Forth : moreover, this fish is found in the south
long before it ought to be there, if we were to believe in Pennant's
theory. It has been deduced, from a consideration of the figures of the
annual takes of many years, that the herring exists in distinct races,
which arrive at maturity month after month ; and it is well known that the
herrings taken at Wick in July are quite different from those caught at
Dunbar in August or September : indeed, I would go further, and say that
even at Wick each month has its changing shoal, and that as one race
ripens for capture another disappears, having fulfilled its mission of
procreation. It is certain that the herrings of these different seasons
vary considerably in size and appearance; and it is very well known that
the herrings of different localities are marked by distinctive features.
Thus, the well-known Lochfyne herring is essentially different in its
flavour from that of the Firth of Forth, and those taken in the Firth of
Forth differ again in many particulars from those caught off Yarmouth.
In fact, the herring never ventures far from the spot
where it is taken. and its condition, when it is caught, is just an index
of the feeding it has enjoyed in its particular locality. The superiority
in flavour of the herring taken in our great land-locked salt-water lochs
is undoubted. Whether or not it results from the depth and body of water,
from more plentiful marine vegetation, or from the greater variety of land
food washed into these inland seas, has not yet been determined ; but it
is certain that the herrings of our western sea-lochs are infinitely
superior to those captured in the more open sea. It is natural that the
animals of one feeding locality should differ from those of another : land
animals, it is well known, are easily affected by change of food and place
; and fish, I have no doubt, are governed by the same laws. But on this
part of the herring question I need scarcely waste any argument.
Moreover, it is now known, from the inquiries of the
late Mr. Mitchell and other authorities on the geographical distribution
of the herring, that that fish has never been noticed as being at all
abundant in the Arctic Regions ; and the knowledge accumulated from recent
investigations has dispelled many of what may be termed the minor
illusions once so prevalent about the life of the herring and other fish.
People, however, have been very slow to believe that fish were subject to
the same natural laws as other animals. In short, seeing that the natural
history of all kinds of fish has been largely mixed up with tradition or
romance, it is no wonder that many have been slow to discard Pennant's
pretty story about the migratory instinct of the herring, and the
wonderful power of sustained and rapid travelling by which it reached and
returned from our coasts. Even Yarrell wrote in a weak uncertain tone
about this fish ; indeed his account of it is not entitled to very much
consideration, being a mere compilation, or rather a series of extracts,
from other writers.
It was not till the year 1854 that anything like an
authentic contradiction to Pennant's theory was obtained. Before that time
one or two bold people asserted that they had doubts about the migration
story, and thought that the herring must be a local animal, from the fact
of its being found on the British coasts all the year round ; while one
daring man said authoritatively, from personal knowledge, that there were
no herrings in the Arctic seas. During the year I have mentioned, a paper,
which was communicated to the Liverpool Meeting of the British Association
by Mr. Cleghorn of Wick, directed an amount of public attention to the
herring-fishery, which still continues, and which, at the time, was
thought sure ultimately to result in an authentic inquiry into the natural
and economic history of that fish. Such an investigation has since been
made by persons qualified to undertake the task, and the result of their
inquiries summed up in a most interesting report, which, along with the
evidence taken by the Commissioners, I shall have occasion to refer to in
another part of the present chapter; the labours of Cleghorn, Mitchell,
and others, claiming priority of notice, as the ideas promulgated by these
gentlemen, although often hotly opposed and combated, have gone a great
way to guide public opinion on the subject, and have evidently helped to
influence recent investigators.
In his paper communicated to the British Association at
Liverpool, Mr. Cleghorn stated that, living at Wick, the chief seat of the
fishery - " the Amsterdam of Scotland " in fact - his attention had been
directed to the herring-fishery by the fluctuations in the annual take.
Mr. Cleghorn believes the fluctuations in the capture to be caused by "overfishing,"
as in the case of the salmon, the haddock, and other fish. The points
brought forward by Mr. Cleghorn in order to prove his case were the
following:-I. That the herring is a native of waters in which it is found,
and never migrates. 2. That distinct races of it exist at different
places. 3. That twenty-seven years ago the extent of netting employed in
the capture of the fish was much less than what is now used, while the
quantity of herrings caught was, generally speaking, much greater. 4.
There were fishing stations extant some years ago which are now exhausted;
a steady increase having taken place in their produce up to a certain
point, then violent fluctuations, and then final extinction. 5. The
races of herrings nearest our large cities have disappeared first ; and in
districts where the tides are rapid, as among islands and in lochs, where
the fishing grounds are circumscribed, the fishings are precarious and
brief; while on the other hand extensive seaboards having slack tides,
with little accommodation for boats, are surer and of longer continuance
as fishing stations. 6. From these premises it follows that the extinction
of districts, and the fluctuations in the fisheries generally, are
attributable to overfishing. In the portion of this work bearing on the
fishery I shall again have occasion to refer to Mr. Cleghorn's
investigations on the subject of the netting employed, but it occurred to
me to state Mr. Cleghorn's theory at this place, as it has been the
key-note to much of the recent discussion on the subject of the natural
history of the herring. Before the reading of Mr. Cleghorn's statistics,
the natural history of the herring was not well understood even by
naturalists; so difficult is it to make observations in the laboratories
of the sea. Only a few persons, till recently, were intimate with the
history of this fish, and knew that, instead of being a migratory animal,
as had been asserted by Anderson and Pennant, the herring was as local to
particular coasts as the salmon to particular rivers.
The late Mr. J. M. Mitchell, in a paper which lie read
before the British Association at Oxford, settled with much care and very
effectually the geographical part of the herring question. His idea also
is that the herring is a native of the coast on which it is found, and
that immediately after spawning the full-sized herrings make at once for
the deep waters of their own neighbourhood, where they feed till the
spawning season again induces them to seek the shallow water. Mr. Mitchell
gives his reasons, and states that the herrings resorting to the various
localities have marked differences in size, shape, or quality ; those of
each particular coast having a distinct and specific character which
cannot be mistaken ; and so well determined are those particulars, that
practical men, on seeing the herrings, can at once hit upon the locality
from whence they come ; as, indeed, is the case with salmon, turbot, and
many other fishes and crustaceans.
On the southern coast of Greenland the herring is a
rare fish ; and, according to Crantz, only a small variety is found on the
northern shore, nor has it been observed in any number in the proper icy
seas-as it would undoubtedly have been had it resorted thither in such
innumerable quantities as was imagined by the naturalists of the last
century. Another proof that the herring is local to the coasts of Britain
lies in the fact of the different varieties brought to our own markets. As
expert fishers know the salmon of particular rivers, so do some men know
the different localities of our herring from merely glancing at the fish.
Experienced fishmongers can tell the different localities of the same
kinds of fish as easily as a farmer can tell a Cheviot sheep from a
Southdown. Thus they can at once distinguish a Severn salmon from one
caught in the Tweed or the Spey, and they can tell at a glance a Lochfyne
matie from a Firth of Forth one.
Turning now to the report of the Commissioners already
referred to, we obtain some interesting information as to the spawning and
growth of the herring. Upon these branches of the subject the public have
hitherto been very ill informed. Yarrell's account of this particular fish
is a mere compilation from Dr. M`Culloch, W. H. Maxwell, Dr. Parnell, and
others, and is thus very disappointing. Again, the account in the
Naturalist's Library is compressed into five
small pages, referring chiefly to authorities on the subject, with
quotations from Yarrell ! It is only by searching in Blue Books, by
perusing much newspaper writing of a controversial kind, and by arduous
personal inquiry, as well as by making a minute study of the fish, that I
have been able to complete anything like an accurate
precis of the natural and economic history of this very
plentiful fish.
As to the periods at which herrings spawn, the
Commissioners inform us that they met with " singularly contradictory "
statements, and after having collected a large amount of valuable
evidence, they
arrived at the conclusion that herrings spawn at two seasons of the year -
viz. in the spring and autumn. They have no evidence of a spawning during
the solstitial months -viz. June and December ; but in nearly all the
other months gravid herrings are found, and the Commissioners assert that
a spring spawning certainly occurs in the latter part of January, as also
in the three following months, and the autumn spawning in the latter end
of July, and likewise in the following months up to November. " Taking all
parts of the British coast together, February and March are the great
months for the spring spawning, and August and September for the autumn
spawning." The spawn, it may be stated in passing, is deposited on the
surface of the stones, shingle, and gravel, and on old shells, at the
various spawning places, and it adheres tenaciously to whatever it happens
to fall upon. This, as will be seen, brings us exactly back to Mr.
Cleghorn's ideas of the herring existing in races at different places and
in separate bodies, and thereby rendering the fluctuations of the great
series of shoals at Wick more and more intelligible, especially when we
take into account the fact that winter shoals are now found at that place,
giving rise to what may ultimately prove a considerable addition to the
great autumn fishery yet carried on there.
As to the question of how long herrings take to grow,
from the period of the deposition of the egg, there are various opinions,
for no naturalist or practical fisherman has been able definitely to fix
the time. There is reason to believe, we are told in the report, that the
eggs of herrings are hatched in, at most, from two to three weeks after
deposition. This is very rapid work when we consider that the eggs of the
salmon require to be left for a period of ninety or a hundred days, even
in favourable seasons, before they quicken into life, and that the eggs of
a considerable number of fish are known to take a much longer period than
three weeks to ripen. The rate of growth of the herring, and the time at
which it begins to reproduce itself, are not yet well understood ; indeed,
it seems particularly difficult to fix the period at which it reaches the
reproductive stage. As an example of the numerous absurd statements that
have been circulated about fish, the reader may study the following
paragraph:-" Old fishermen-about Dunbar say the way herring
spawn is -first, the female herrings deposit their roe at some convenient
part on sand or shingly bottom; second, the male fish then spread their
milt all over the roe to protect it from enemies, and the influence of the
tide and waves from moving it about. The fishermen also say that when the
young herrings are hatched they can see and swim ; the milt covering
bursts open, and they are free to roam about. Some naturalists think the
roes and milts of herring are all mixed together promiscuously, and left
on the sands to bud and flourish. The fishermen's idea seems to be the
most likely of the two opinions."
I have had young herrings of all sizes in my
possession, from those of an inch long upwards. The following are the
measurements of a few of my specimens which were procured about the end of
February, and not one of which had any appearance of either roe or milt,
while some (the smaller fish) were strongly serrated in the abdominal
line, and others, as they advanced in size, lost that distinguishing mark,
and were only very slightly serrated. The largest of these fish--and they
must all have been caught at one time-was eight inches long, nearly four
inches in circumference at the thickest part of the body, and weighed a
little over two ounces. The smallest of these herring fry did not weigh a
quarter of an ounce, and was not quite three inches in length. One of
them, again, that was six inches long, only weighed three-quarters of an
ounce ; whilst another of the same lot, four and a half inches long,
weighed a quarter of an ounce exactly. I do not propose at present to
enter at great length into the sprat controversy ; but, if the sprat be
the young of some one of the different species of herring, as I take leave
to think it is, then the question of its growth and natural economy will
become highly important. Some people say that the herring must have
attained the age of seven
years before it can yield milt or roe, whilst a period
of three years has been also named as the ultimate time of this event ;
but there are persons who think that the herring attains its reproductive
power in eighteen months, while others affirm that the fish grows to
maturity in little more than half that time. If the average size of a
herring may be stated as eleven and a half inches, individual fish of
Clupea harengus have been found measuring seventeen inches, and full
fish have been taken only ten inches in length, when should the example,
noted above as being eight inches long, reach its full growth I and how
old was it at the time of its capture? And, again, were the fish-all taken
out of the same boat, be it observed, and caught in the same shoal-all of
one particular year's hatching? Is this the story of the parr over again,
or is it the case that the fishermen had found a shoal of mixed
herrings-some being of one year's spawning, some of another ? I confess to
being puzzled, and may again remind the reader that my largest fish had
never spawned, and had not the faintest trace of milt or roe within it.
Then, again, as to the time when herrings spawn, I have over and over
again asserted in various quarters that they spawn in nearly every month
of the year-an assertion which has been proved by official inquiry.
As to the place of spawning, development of the ova,
and other circumstances attendant on the increase of the herring, I
promulgated the following opinions some years ago, and I see no reason to
alter them :-The herring shoal keeps well together till the time of
spawning, whatever the fish may do after that event. Some naturalists
think that the shoal breaks up after it spawns, and that the herring then
live an individual life, till again instinctively moved together for the
grand purpose of procreating their kind. It is quite clear, I think, that
herring move into shallow water because of its increased temperature, and
its being more fitted in consequence for the speedy vivifying of their
spawn. The same shoal will always gather over the same spawning ground,
and the fish will keep their position till they fulfil the chief object of
their life. The herrings will rise buoyantly to the surface of the water
after they have spawned ; before that they swim deep and hug the ground.
The herring, in my opinion, must have a rocky place to spawn upon, with a
vegetable growth of some kind to receive the roe ; shoals may of course
accidentally spawn on soft ground. It is not accurately known how long a
period elapses till the spawn ripens into life. I think, however, that
herring spawn requires a period of about ten weeks to ripen. It is known
that young herrings have appeared on a spawning ground in myriads within
fifty days after the departure of a shoal, and fishermen say that no spawn
can be found on the ground after the lapse of a few weeks from the visit
of the gravid shoal-that the eggs in fact have come to life, and that the
fish are swimming about.
It is generally known that the sprat (Clupea
sprattus) is a most abundant fish. The fact of its great abundance has
induced a belief that it is not a distinct species of fish, but is, in
reality, the young of the herring. It is true that many distinguishing
marks are pointed out as belonging only to the sprat -such as its serrated
belly, the relative position of the fins, etc. But there remains, on the
other side, the very striking fact of the sprat being rarely found with
either milt or roe ; indeed, the only case I know of this fish
having been found in a condition to perpetuate its species was detailed by
the late Mr. Mitchell, who exhibited before one of the learned societies
of Edinburgh a pair of sprats having the roe and milt fully developed. Dr.
Dod, an ancient anatomist, says: "It is evident that sprats are young
herrings. They appear immediately after the herrings are gone, and seem to
be the spawn just vivified, if I may use the expression. A more undeniable
proof of their being so is in their anatomy ; since, on the closest
search, no difference but size can be found between them." After the
nonsense which was at one time written about the parr, and considering the
anomalies of salmon-growth, it would be unsafe to dogmatise on the sprat
question. As to the serrated belly, we might look upon it as we do the
tucks of a child's frock - viz. as a provision for growth. The fin-rays of
this fish have also been cited in evidence as not being the same in number
as those of the herring, but as I can testify from actual counting, the
finrays of the latter fish vary considerably, therefore the number of
fin-rays is not evidence in the case. The slaughter of sprats which is
annually carried on in our seas is, I suspect, as decided a killing of the
goose for the sake of the golden eggs as the grilse-slaughter which is
annually carried on in our salmon rivers.
The herring is found under four different conditions:-
1st, Fry or sill; 2d, Maties or fat herring; 3d, Full herring; 4th,
Shotten or spent herring. All herrings under five or six inches in length
come under the first denomination. The matie is the finest
condition in which a herring can be used for food purposes; and if the
fishery could be so arranged, that is the time at which it should be
caught for consumption. At that period it is very fat, its feeding-power
being all developed on its body ; the spawn is small, the growth of the
roe or milt not having yet demanded the whole of the nutriment taken by
the fish. A full herring is one in which the milt or roe is fully
developed. The maties develop into spawning herring with great
rapidity -in the course of three months, it is said. The herrings at the
spawning season come together in vast numbers, and proceed to their
spawning places in the shallower and consequently warmer parts of the sea.
As Gilbert White says, "The two great motives which regulate the brute
creation are love and hunger; the one incites them to perpetuate their
kind, the latter induces them to preserve individuals." In obedience to
these laws the herring congregate on our coast, for there only they find
an abundant supply of food to mature with the necessary rapidity their
milt and roe, as well as a sea-bottom fitted to receive their spawn; and
they are thus brought within the reach of man at what many persons
consider the wrong time of their life.
As to this division of the question, it has been said
that it matters not at what period you take a herring, whether it be old
or young, without or with spawn ; that fish cannot again be caught, and
will never spawn again ; and it is argued, therefore, that the taking of
fish in " the family way " no more prevents it from reproducing than if it
had been killed in the condition of a matie. The same argument was
used in the case of the young salmon; and it was asked : If you kill all
your grilse, where are you to find your salmon ?
The- herring breeds, then, and is caught in greater or
lesser quantities, during every month of the year. There is no general
close-time for the herring in Scotland. How is it that the time selected
by fishermen for the capture of this fish corresponds with the period when
it is a crime to take a salmon ? If a gravid salmon be unwholesome, is a
gravid herring good for food? Do not the same physical laws affect both of
these fish? There cannot be a doubt that at the period of spawning, this
fish, as well as all other fish, is in its worst condition so far as its
food-yielding qualities are concerned, because at that time of its life
its whole nutritive power is exerted on behalf of its seed, and its flesh
is consequently lean and unpalatable. Yet it is a great fact that the time
which the herring selects to fulfil the grandest instinct of its nature is
the very time appointed by man for its capture ! In fact, that is
the period when herrings are at a premium ; they must be "full fish," or
they cannot obtain the official brand; in other words, shotten
herrings-i.e. fish that have spawned-are not of much more than half the
value of the others. When it is taken into account that each pair of full
fish (male and female) are killed just as they are about to give us the
chance of obtaining an increase of the stock to the extent say of thirty
thousand, the ultimate effect must be to disturb and cripple the producing
powers of the shoal to such a degree that it will break up and find a new
breeding-ground, safe for a time perhaps from the spoliation of the greedy
fishermen. The Lochfyne Commissioners gave as a reason for their
non-recommendation of a close-time the fact, that were there to be a
cessation from labour, the enemies of the herring would so increase that
the jubilee given would be nugatory. But surely there is a great want of
logic in this argument ! How is it that a close-time operates so
favourably in the case of the salmon-not only a seasonal close-time, but a
weekly one as well ? Would not the herring, with its almost miraculous
breeding-power, increase in the same ratio, or even in a greater ratio
than its enemies, especially, if, as the Commissioners tell us, and we
believe, it is engaged in multiplying its kind during ten months of the
year ? Are not the enemies of the herring at work during the fishing
season as well as at other periods ? I could understand the logic of
denying a close-time on the ground that, as the herring never ceases
breeding, it is impossible to fix a correct period. But, according to the
deliverance of the Commissioners, a close-time is possible. I have ever
been of opinion, notwithstanding the practical difficulties that would
have to be encountered in carrying it out, that the want of a close-time,
especially for the larger kinds of sea-fish, is one of the causes which
are so obviously affecting the supplies. It is certain also, from chemical
and sanitary investigation, that all fish are unwholesome at the period of
spawning; the salmon at that time of its life is looked upon as being
little better than carrion. But, without dwelling on this phase of the
question, or considering the effect of unwholesome fish on the public
health, I must point out most strongly that the want of a well-defined
close-time is one of the greatest and severest of our fish-destroying
agencies. We give our grouse a breathing space; nay, we sometimes afford
to that bird a whole jubilee year ; we do not shoot our hares during
certain months of the year, nor do we select their breeding season as the
proper time to kill our oxen or our sheep ; but we do not at dinner-time
object to an entree composed of cod-roe, and we evidently rather
believe in the propriety of killing only our seed-laden herrings ! This
lavish destruction of fish-life has arisen in great part from the
well-known fecundity of all kinds of sea-fish, which has given rise to the
idea that it is impossible to exhaust the shoals. But when it is
considered that this wonderful fecundity is met by an unparalleled
destruction of the seed and also of the young fish, we need not be
astonished at the ever-recurring complaint of scarcity. An old and
probably exaggerated complaint has been lately revived that the beam-trawl
is one of the most destructive engines employed in the sea, five hundred
tons of spawn being destroyed by trawlers in twenty-four hours ! There can
be no doubt that there is annually an enormous waste of fish-life through
the accidental destruction of very large quantities of spawn,-
herring-spawn as well as all other kinds.
As to the food of the herring, the report already
alluded to tells us that it " consists of crustacea, varying in size from
microscopic dimensions to those of a shrimp, and of small fish,
particularly sand-eels. While in the matie condition they feed
voraciously, and not unfrequently their stomachs are found immensely
distended with crustacea and sand-eels, in a more or less digested
condition." I have personally examined the stomachs of many herrings, and
have found in them the remains of all kinds of food procurable in the
place frequented by the particular animal examined-including herring-roe,
young herrings, sprats, etc. ; but the sand-eel seems to be its favourite
food.
One of the wonders connected with the natural history
of the herring is the capricious nature of the fish. It is always changing
its habitat, and, according to vulgar belief, from the most curious
circumstances. I need not add to the necessary length of this chapter by
giving a great number of instances of the capricious nature of the
herring; but I must cite a few, in order to make my recapitulation of
herring history as complete as possible, and at the same time it is proper
to mention that superstition is brought to bear on this point. The
fishermen of St. Monance, in Fife, used to remove their church-bell during
the fishing season, as they affirmed that its ringing scared away the
shoals of herring from the bay ! It has long been a favourite and popular
idea that they were driven away by the noise of gun-firing. The Swedes say
that the frequent firings of the British ships in the neighbourhood of
Gothenburg frightened the fish away from the place. In a similar
manner and with equal truth it was said that they had been driven away
from the Baltic by the firing of guns at the battle of Copenhagen !
"Ordinary philosophy is never satisfied," says Dr. M`Culloch, " unless it
can find a solution for everything ; and it is satisfied for this reason
with imaginary ones." Thus in Long Island, one of the Hebrides, it was
asserted that the fish had been driven away by the kelp-manufacture, some
imaginary coincidence having been found between their disappearance and
the establishment of that business. But the kelp fires did not drive them
away from other shores, which they frequent and abandon
indifferently, without regard to that work. A member of the House of
Commons, in a debate on a Tithe Bill in 1835, stated that a clergyman,
having obtained a living on the coast of Ireland, signified his intention
of taking the tithe of fish, which was, however, considered to be so
utterly repugnant to their privileges and feelings, that not a single
herring had ever since visited that part of the shore !
The most prominent members of the Chupediae are
the common herring (Clupea harengus) ; the sprat, or garvie (Clupea
sprattus) ; and the pilchard, or gipsy herring (Clapea pilchardus).
The other members of this family are the anchovy, and the Alice and
Twaite shad ; but these, although affording material for speculation to
naturalists, are not of great commercial importance.
Before concluding this chapter I wish to say a few
words about a point of herring economy, which has been already alluded to
in connection with the special commission appointed to inquire into the
trawling system-viz, as to the natural enemies of the herring, the most
ruthless of which are undoubtedly of the fish kind, and whose destructive
power, some people assert, dwarfs into insignificance all that man can do
against the fish:- "Consider," say the Commissioners, "the destruction of
large herring by cod and ling alone. It is a very common thing to find a
codfish with six or seven large herrings, of which not one has remained
long enough to be digested, in his stomach. If, in order to be safe, we
allow a codfish only two herrings per diem, and let him feed on
herrings for only seven months in the year, then we have 420 herrings as
his allowance during that time; and fifty codfish will equal one fisherman
in destructive power. But the quantity of cod and ling taken in 1861, and
registered by the Fishery Board, was over 80,000 cwts. On an average
thirty codfish go to one cwt. of dried fish. Hence, at least 2,400,000
will equal 48,000 fishermen. In other words, the cod and hug caught
on the Scotch coasts in 1861, if they had been left in the water, would
have caught as many herring as a number of fishermen equal to all those
in Scotland, and six thousand more, in the same year ; and as the cod
and ling caught were certainly not one tithe part of those left behind, we
may fairly estimate the destruction of
herring by these voracious fish alone as at least ten
times as great as that effected by all the fishermen put together." As to
only one of the numerous land enemies of the herring, the late Mr. Wilson,
in his Tour round Scotland, calculated that the gannets or solan
geese frequenting one island alone-St. Kilda-picked out of the water for
their food 214 millions of herrings every summer ! The shoals that can
withstand these destructive agencies must indeed be vast, especially when
taken in connection with the millions of herrings that are accidentally
killed by the nets, and never brought ashore for food purposes. The work
accomplished by these natural enemies of the herring, which has been going
on during all time, does not however affect my argument, that by the
concentration on one shoal of a thousand boats per annum, with an
annually-increasing net-power, we both so weaken and frighten the shoal
that it becomes in time unproductive. As the late Mr. Methuen said in one
of his addresses: " We have been told that we are to have dominion over
the fish of the sea, but dominion does not mean extermination."
