LOW MOOR, July 1st, 1846.
To the Editor of "The Times."
The attempt which is now making to amend the laws relating to the Salmon fisheries, appears to run such a great risk of failure, from the opposition of interested persons, that I think a short sketch of the defects of the present laws and their effects on the breed of fish, and a comparison of them with the proposed amendment, may be interesting to some of your readers, and may, perhaps, induce some influential gentlemen to throw their influence into the right scale, in the approaching discussion on this subject.
The Salmon fisheries in former times appear to have supplied food for a large portion of the people, as there are still traditions current on the banks of various rivers in the north, that the indentures of apprenticeship always stipulated that the apprentice should not be compelled to eat Salmon more frequently than three days a week, and however exaggerated this story may appear at the present day, I hope to succeed in showing that it is neither improbable that it has been so, nor impossible that it may be so again,--if good laws are made for their protection, and these laws are properly enforced. At present there is no doubt the fisheries are rapidly declining, and in some rivers which used to have a good many Salmon in them, and which used to swarm with Smolts (or fry) in the spring within my remembrance, they are now rarely seen. To show their scarcity I may mention a circumstance which occurred in the Wharfe, which was formerly one of the finest rivers in Yorkshire for Salmon. A few years ago a pair of Salmon were seen on a spawning bed in the Wharfe, about forty miles from its mouth. This became known at the anglers' club, and it was deemed so important to preserve them, that the club divided themselves into three or four watches, and guarded the spawning bed night and day, whilst the fish were spawning, and this spawning lasted about a week.
Here in the Ribble the Salmon fisheries are not quite so near extinction (though they are rapidly progressing in that direction), for although we are very seldom allowed to see or catch fish in seasonable condition, a good many come up the river to spawn, though very few of them ever do so, and very few of those that do ever reach the sea again. The reason is obvious, no one here has any interest in preserving the spawning fish, and they are openly killed by the poachers, who never dream of being prosecuted for it. I am credibly informed that in a stream not five hundred yards from where I write, sixty spawning fish were killed last winter. Some years ago one gang of poachers killed three hundred Salmon on the spawning beds in one season, and sold potted Salmon roe (which is a most destructive bait for Trout) to the value of L20.
In the Lune the proprietors of the fisheries near Lancaster sent men to protect the spawning fish in the streams above; but these men were warned off by the landed proprietors, who said, If you catch all the good fish you must at least allow us to catch the bad ones. In the Tweed and its tributaries it used to be quite as bad (what the new Scotch law has done I do not know), but a poacher who gave evidence before the Committee of the House of Commons in 1825 said that he had assisted to take four hundred Salmon at one haul in close time in the Tweed.
Sir Walter Scott's vivid description of burning the water, which occurs in "Guy Mannering," shows that he knew how to kill Salmon in close time. In fact, his account, and that of Hogg (the Ettrick Shepherd), show that both were regular black fishers.
There are various devices for killing the fish in close time: they are speared, netted, and hooked on the spawning beds, and when the rivers get low, gangs of idle fellows range up and down on the banks, stoning and beating the water by poles, or, what is more effective still, a large bone, or horse's skull, and by fastening a cord to it, one end of which is passed to each side of the river, they draw this skull up and down in the pools where they know there are Salmon, and the fish are so foolish and timid, that they thrust their heads under any stone or cover they can find, and are taken without trouble; it being common enough in such cases to slip a noose over the tail, then tightening it, and the fish is hauled out immediately.
Then again, gentlemen who want to have the reputation of being skilful anglers, employ their game-keepers to find the Kippers (Scottice Kelts) or spawned fish in the pools, which is a very easy matter in low water, and dropping a hook baited with a lob worm before their noses, it is greedily taken, and the poor fish (which are unfit for food) are caught. It is then trumpeted forth to the angling world that Mr. A. B. has had splendid sport--he has caught a dozen Salmon with the rod in a single day, meaning it to be understood that these fish have been caught with the fly. I by no means uphold these practices, neither do I think them very deserving of censure in the present state of the law, for all the good fish are taken near the mouths of the rivers.
This leads me to consider the defects of the present law, which is by no means adapted to protect and increase the breed of Salmon.
In the first place, the close time is too short. It commences in the Ribble nominally (for in reality the fish are openly killed all the year through) on the 15th September, and ends on the 31st of December; whereas it ought to extend to the end of April, for the following reasons. A very large proportion of the fish are spawning in January and February, and I have even seen a spawning fish as late as the 3rd of April. In the evidence given before the House of Commons in 1825, it was proved by a fisherman from the Tweed, that in March for one clean fish that was caught there were ten caught that were not so, as they were either fish that had not spawned, or Kelts, that is, fish which have finished spawning but have not returned to the sea, and are then flabby, unwholesome, and unfit for food. A very large proportion of these Kippers or Kelts do not go to the sea until April, and not then without there is a fresh in the river, for, like the Smolts, they seem disposed to remain in the rivers until they can avail themselves of the assistance of a flood, to enable them more easily to reach the sea.
Another defect in the present law is that it fails to secure a supply of good fish to the upper proprietors. There are no provisions in it (or they are not enforced) for giving the fish a free passage, no prohibition of nets, traps, or devices for stopping them in their progress up the rivers. No daily or weekly close time, but everywhere there is so short-sighted a selfishness, that it is completely realizing the fable of the man who killed the goose which laid the golden egg. The fisheries are declining so rapidly, that unless something is done, and done quickly, the breed of Salmon will be extinct in the rivers in this neighbourhood.
Again, there is no power to appoint or pay conservators, and without their assistance there is no chance of preserving Salmon in the spawning beds. Game-keepers are most certainly not to be depended upon.
In pointing out the defects of the present laws I have, in fact, given an opinion how they should be remedied. I would extend the close time from the end of September to the end of April. I would establish a daily close time, allowing no net, device, or engine to be employed in taking Salmon between sunset and sunrise above tideway in any river; and below, I would only allow nets to be set for twelve hours per diem. I would appoint conservators, whom I would pay by a tax on the fisheries on the whole course of the river, which tax should be determined by a valuation of the fisheries, and paid accordingly. I would fine every one who sold, used, or had in his possession any potted or prepared Salmon roe for the purpose of angling, and I would give conservators the power of examining all mill goits and races, for the purpose of seeing that no unfair practices were resorted to for the taking of Salmon or Salmon fry; and I would give the upper proprietors the power of making any alterations in mill weirs and dams which did not impair their stability or the efficiency of the water power. If some such enactments as these were made and properly enforced, there is no doubt Salmon would swarm in every river, for their fecundity is such, that a very few Salmon spawning in a river under favourable circumstances stock it abundantly with Smolts. A large Salmon having not less than 25,000 eggs in it, how soon, with a little forbearance and care, would every river swarm with this delicious fish, even to such a degree as to be a cheap food for the poor! But to obtain such results it must be made the interest of every person to protect them.
In reading over the evidence on the Salmon fisheries, which was given before the House of Commons in 1825, I was exceedingly amused by the reasons given by the tenants of some of the fisheries in Scotland why there should be no weekly close time, and the shifts and evasions practiced by others. One said he paid L7,000 a year rent to the Duke of Gordon for his fishery, and if one day in the week were allowed for close time he would lose L1,000 a year. Another said he kept the close time, but he would allow nobody to go and see whether he kept the free gap open or not. Another proved that he kept open the free passage, but it was also proved that he had a crocodile placed in the gap, painted with very glaring colours, in order to frighten back any fish that attempted to pass. Another sent his boats to break down the stake nets which were set in the estuary, but acknowledged that he kept his own nets set across the river day and night. There would be no difficulty in stocking every suitable river in the kingdom with Salmon, either by putting into them a few pairs of breeding fish, or by artificially fecundating the eggs, and placing them in artificial spawning beds. It is a plan I have frequently adopted, and sometimes successfully; but in other experiments I have failed, from the difficulty of choosing a suitable locality in the river. If too rapid a stream was chosen, the eggs and gravel were all washed away; and if too calm and still a place was selected, the gravel was filled up with sand and mud, and the eggs rotted instead of hatching. I am even of opinion that where there is already a breed of Salmon fry in a river, it is not absolutely necessary that any male Salmon should come up the river in the spawning season, the male Par, or Penks, as we call them in the Ribble, being sufficient to fecundate the eggs. If this is doubted, I would ask how it happens that in the autumn they have fluid milt in them? for as nature makes no unnecessary provisions, for what purpose is this, if not to provide for the possibility of a female Salmon coming alone? These Pars swarm on the Salmon spawning beds.

SUGGESTIONS FOR AN ALTERATION IN THE LAWS REGARDING SALMON.
CLITHEROE, October 12th, 1851.
To the Editor of the "Gardeners' Chronicle."
As the amusement of fly-fishing is one which holds a first place in the opinion of every one who understands it, and as the Trout and the Salmon are the only fish which afford genuine sport to the angler, and as I believe that the latter in some of the southern counties is nearly extinct, whilst the former is far from being abundant, I wish to call the attention of such of your readers as are possessed by the true piscatorial furor, to the facility with which these fish can be bred artificially. And as many experiments have been made under my direction, and having witnessed the results, I unhesitatingly say that there is little risk of failure, if due care be taken.
The experiments of Shaw and Agassiz, my own also included, have proved that fish can be bred artificially. The experiments of Boccius I have not yet tried, although he proposes to arrive at the same result in another manner, and acting in the manner recommended by them, Trout and Salmon have been bred by thousands during the last ten years.
As the season for making the experiment will shortly be here, I hope that those who intend to try the plan will lose no time in looking after their supply of breeding fish.
To begin with Trout:--Catch as many as you can conveniently obtain upon the spawning beds, and examine them carefully one by one, to see that the spawn and milt are in a fit state for exclusion; and also to enable you to separate the males from the females. If they are in a fit state to be operated upon (which may be known by the facility with which the milt and the roe run from them on a slight pressure), squeeze the milt of the males into a little water, and when you have obtained all the milt you can get, add so much water that the mixture remains slightly opalescent--say about equal in colour to a tablespoonful of milk mixed in a quart of water; pour this into a deep dish or bowl, large enough to hold the largest of your female Trouts; take one of these and put it into the water so prepared, and gently squeeze the roe from it whilst the vent is immersed in the water. Do this as quickly as possible, and return the fish into fresh water, and then pour off the water containing the impregnated roe, through a strainer, carefully preserving it for the remaining fish, and immediately return the roe into fresh spring or brook water. Repeat the operation for every female Trout, and you will then have a quantity of impregnated roe, which if properly managed will hatch with great certainty. Have ready as many boxes as you are able to stock with spawn (three feet long, two feet broad, and six inches deep). Fill them to the depth of two inches of river sand, which ought to be previously so well washed that there is not a particle of mud left in it, and upon that put two inches of river gravel, also exceedingly well washed, the pebbles varying in size from a hazel nut to a pigeon or pullet's egg. These boxes must be so placed that the water from a spring will flow into the first, and from the surface of that into the second, and below the whole nest of boxes there ought to be a small reservoir made--say three yards by two and eighteen inches deep, and well gravelled at the bottom. All these matters having been previously arranged, and the water flowing nicely over the gravel, sprinkle the impregnated roe equally over the surface of the gravel, say a quarter of a pint to each box, and it will roll down into the interstices of the gravel and find a bed in which it will remain snugly until the spring, when, about March, if all has been properly managed, you will find, on a careful examination, that the young Trout are coming to life by hundreds. I am very particular in recommending spring rather than brook water, for several reasons. In the first place, brooks are liable to be flooded, and are sometimes so overcharged with sand and mud that the gravel in the spawning-boxes is completely choked with it and the spawn is lost, as I know to my great and frequent disappointments. At other times all is washed away together. In the second place, the gravel of brooks swarms with water-lice (shrimps) and the larvae of aquatic insects, as well as bull-heads and loaches, all of which prey upon the spawn of the Trout and Salmon. In the third place, if you put your spawning-boxes in a brook, you will find it difficult to prevent the escape of the fry when hatched, and you are left in doubt as to the success of your experiment. With spring water all these inconveniences are avoided. But if your watercourse should contain water-lice or aquatic larvae, it is a very easy matter to destroy them before putting in your boxes, with a little salt or quicklime. It is also desirable to cover your spawning-boxes with a wire grating, to exclude the light, and to protect them in severe weather from the chance of being frozen.
When they begin to hatch, open a communication between the boxes and the little reservoir below, and if this communicates with a watercourse in which aquatic plants are growing, so much the better. The fry, as soon as they are strong enough, will make their way into this ditch, and will find abundance of food among the water plants; thence they ought to be able to make their way into the brook, river, or lake which it is intended to store with them. All ducks, wild and tame, should be driven from this ditch, or few of the Trout will be allowed to find their way to their final place of destination.
These rules, with some modification, are applicable to the breeding of Salmon as well as Trout; the only difference being in the mode of placing the female fish, when obtaining the roe, and the size of the gravel in which the spawn is deposited in the boxes. The Salmon is too large a fish to put into the vessels in which the diluted milt is placed, but I think that she should be held by an assistant, in such a manner that the tail and lower part of the body up to the vent are immersed in the water containing the milt. And it is also very necessary to hold her firmly, otherwise a large fish, in the struggles which it makes to get free, is apt to upset the vessel containing the milt, and then the experiment is at an end, at least for the time. Being held firmly by the assistant, as above stated, the belly of the fish must be gently pressed by the hands to promote the exclusion of the spawn, which on exclusion must be gently stirred in the diluted milt, to bring every grain into contact with it; but the roe ought not to remain in contact with the milt a minute, if it can sooner be got out, as I have found that if the diluted milt be too strong, or if the ova remain too long in contact with it, they become opaque, and never hatch at all, apparently because they are over-impregnated. In the ordinary way in which Salmon and Trout are bred, the milt must be largely diluted with water, and the contact between the milt and ova can only be momentary, for the streams in which these fish spawn (particularly the Salmon) are so rapid, that the milt on exclusion must be carried away immediately.
There is another method, which is preferred by Ramsbottom, to the one I have been describing, and it is certainly less troublesome. This is to take the ova from the female fish in the first place (taking care to exclude the air from it, by immersing the fish into water up to the vent), and when all the roe has been collected into a large bowl or basin, then mix the milt with it, the same diluted in the proportion which has been before described, namely, until the water which covers the roe becomes lightly opalescent.
