Part 6

The Course of laying the Great Waters Dry.

Before I come to the business of fish, I will finish what I had to say about ponds, and the conduct of them; and of that only remains to speak of the course of laying them dry.

As for the smaller waters, I have touched what concerns them already; as for the greater, or principal ponds, proceed thus:

In October, or after, draw the sluice of the first made pond, and lay it as dry as possible you can. It may be the sluice, especially if the pond be many acres, will not vent the water suddenly. That is of no great import, because, as the waters fall, you will have opportunity of fishing with nets, and so clear the fish by degrees; which left to the last, will be too great a burden to clear, and will not be done without damage; besides, the hurry will disorder every thing. If the sluice will not vent all the water from the pan, a labourer or two will soon throw it out with scuppets. Here you find the use of the channels of diversion, spoke of before; for they will keep off all land-waters, if the time should prove rainy, and so permit the pond to empty, and continue dry, which you could not answer for a day without them; and therefore they should be made on both sides of the waters, on each hill one, which will defend the shot of these hills, that otherwise would retard the work.

When your pond is dry, and thus secured, keep it so all summer, and you may make a profit of the soil sufficiently, either by ploughing or feeding. And at Michaelmas next, or a little sooner, let fall the sluice, and turn in all the water you can, that the pond may fill, and at the being near full, it is ready to receive the stock again.

At the same time lay another dry, proceeding as before; which you may do alternately during your whole life: nay, if you have but two great ponds, this is the best course, and will turn most to the profit and feed of the fish, as I shall shew when I speak of feeding.

If your stock be very great, you may let your ponds stand full two or three years, but not longer, unless you delight to see starved lean fish; for such they will certainly be, unless you keep an under-stock by three-fourths continuing in the same water four or five years. And it is a certain rule, that the oftener waters are laid dry, the better the feed of the fish shall be, and more shall be maintained. And a little experience will demonstrate the advantage to be great, as to the size, fatness, and sweetness of the fish.

When your pond is dry, concern not yourself to carry out the mud for the first fourteen or fifteen years; and then let it be only out of the pan whence you took the earth to raise the bank, but never break the turf of the rest of the ground flowed: but when it comes to be a yard thick in mere mud, it is good to take it out; for though mud be good to improve ground, yet, when it is taken from the pond, down to the dead earth, your ground and soil are depauperated, and the water by consequence, which cheats the fish, that is, yourself.

Of the Breeding of Fish.

Having done with ponds, the manner of making, preserving, and using them, I intend next to discourse of fish, and how best to dispose them to maintain the waters in full stock: but before I come to the stocking of waters, I must speak of the course of breeding fish, whereby the stock is to be recruited and supplied.

Some have thought, that great difference is to be found in the sorts of carps, some whereof are more apt to grow up to a great size, others to spread and look thick, and others for the sweetness of the meat. I do not deny but there may be some difference, but I cannot esteem it so considerable, as to be worth the looking after. Varieties in nature are infinite, and in the several breeds of fish, as of other creatures: yet I have not observed so much of it in carps, that I could tell how to distinguish them, where I could promise myself better success with one sort than another. This is a nicety which fishmongers, that make a trade of buying and selling, talk of, intending it only as a topic of mystery, which all trades affect, and to have something to say for valuing or undervaluing, as they sell or buy, to justify in their talk the prices they propose to take or give; therefore this nicety is left to them.

I do yet believe, that a sort of fish, bred in great numbers in bad waters, over-stocked, and almost starved, may in process of time degenerate, and both lose a good shape, and be less apt to grow up to a due greatness, than others that have been better descended of a cultivated stock: and on the other side, it is no less possible, that by coming into good quarters, fish may improve and mend; so that a gentleman is to expect the goodness of his fish from the cleanness of his waters, and the plenty of their feed, and not from any choice of his stock or breed; and let him get them where he may, if well ordered, he may assure himself they shall answer his expectations.

It is a common observation, that some waters will, and others will not breed. It is my experience, that most waters, the first year after having lain dry a summer, do breed, and that numerously, especially carps, which I have known increase to such an incredible fry, that I have been troubled how to dispose them, so as to have them again after three or four years, when they became good stock for great waters. Eels and perch are of very good use to keep down the breed of fish; for they prey much upon the spawn and fry of bred fish, and will probably destroy the superfluity of them.

The quality of breeding is scarce to be found out by any certain symptom; for some very promising ponds do not prove useful that way. The best indication I know of a breeding pond, is, when there is good store of rush and grazing about it, and gravelly shoals, such as horse-ponds usually have. When a water takes thus to breeding, with a few milters and spawners, two or three of each, you may stock a country.

As for pike, perch, tench, roach, &c. they are observed to breed in almost any waters, and very numerously; only eels never breed in perfect standing waters, and without springs; and in such are neither found, nor increase, but by putting in; but where springs are, they are never wanting, though not put in: and which is most strange of all, no person ever saw in an eel the least token of propagation, either by milt or spawn in them; so that whether they breed at all, and how they are produced, are questions equally mysterious.

The Manner of Stocking Waters.

I have found a great analogy between the stocking waters with fish, and pastures with cattle; and that the same conduct and discretion belong to both. Waters may be over-stocked, as pastures often are; so both may be under-stocked. The latter is the less error; for if you over-stock, you lose the whole summer’s seed; if you under-stock, you lose only the rest of your profit; what you do seed, is much the better, and turns to account by more ready sale. So also of beasts; some of the same age and seeding will not thrive so well as others. I have found the like in my fish. And waters themselves, like pastures, have varieties of goodness; some will raise carps from five to eighteen inches, in five years; others will not do it in ten. This is most sensible between your great waters made upon a fall, and the small standing waters, which have more inconveniencies, and are liable to frosts, and other casualties, more than the others are.

Therefore I propose, that the smaller waters should be used as nurseries, and either to breed, or be stocked with the bred fry of other waters, to raise them to a fitness for stores in your principal feed; that is, to six or eight inches. And of these bred fry, you may put one hundred into four rods square of water, or near that proportion, and fail not to remove them in two years time; and so you will have good recruits of stores for your greater waters.

And thus the many thousands of bred fish that you will have upon the draining your great waters, which many are apt to slight, may be sent several ways to the waters about that and your neighbour’s grounds, and there fed up like chickens, and in time turn to great profit, as I shall shew; therefore they ought not to be slighted, but carefully to be preserved; the rather, because considering a pond (as I propose) will, though but four acres, feed up one thousand six hundred carps in two, and perhaps in one year, from ten to eighteen inches, fit for your table-presents, or sale. How is it possible you should restock your waters the winter after, without this providential forecast, whereby you have magazines of fish in other ponds, fit stores to supply your occasion?

Now, as for your great and principal waters, it is hard to assign a certain proportion for the stock; but perusing the methods I propose, you will soon come to the knowledge what stock the waters will carry; for laying a pond dry every year, you will see the fish well fed, or else thin and lean; and accordingly you judge whether the stock was too little or too much for the water. Thus, by the thickness or fatness of cattle, you judge if your ground will carry more or not; and both as to species and number of fish, experience must be your guide in the stocking of waters.

However, to save loss of time, which you must sustain by making your own experience, I will give the best directions I can, for the first entry upon your business, and not leave the matter wholly in the dark.

If the pond be supplied with a white fat water upon great rains, you may put into it at first three hundred carps per acre, in case there be three or four acres, else not so many. And it will be expedient to put in forty or fifty tenches for a trial, because this sort of water is most proper for carp; but being laid dry, sometimes may prove well for tenches also, which, when thriven, are a very good fish; but this proof by trial must determine.

You may add perches to any number, and not hurt the water: I propose six hundred; for though they are great breeders, being also fishes of prey, they devour their own species as much, if not more than any other; and by destroying the fry of bred fish, they preserve the food for the maintenance of their feeders, which the fry would intercept; so do good rather than harm. I took once out of a perch’s belly of ten inches, ten other perches. This is esteemed one of the best sorts of fresh-water fish, and therefore deservedly to be encouraged.

Have a great care of putting bream in this sort of waters; for they will grow up very slowly, though at last they will be great; but in the mean time they breed so infinitely, and such a slimy nasty fry, as both robs and fouls the water, making it unfit for the other fish. But when a water is ten or twelve acres, and fed with some brook, winter and summer, they will do very well; otherwise not to be made use of.

As for pike, which are inferior to no fresh-water fish, and now more esteemed than ever, being less plentiful upon draining the fens, and so harm more; they are dangerous guests in the great waters; for if grown large, they will devour and destroy the best fish, and depopulate the water. But thus far you may trust them; if you can procure one hundred jacks once in two years not exceeding nine inches, you may put them with the carps into your great waters, so as your carps are not under nine or ten inches; but take care that they stay not above two years, and then send them to their peculiar ponds, and feed them as I shall hereafter discourse, and so they will grow to be very large and fine fish, which you would not want.

I cannot advise the stocking great standing waters with eels, for they grow slow, and being of an indifferent size, will be lean and dry; but in moats, which have the sinks of an house drain into it, is proper enough for them, and they will thrive in it. It is a sort of fish, as I noted, that belongs to a springy water.

These directions belong to the first stocking of new-made ponds, which, as to feeding, lie under a disadvantage; the reason I have touched, and is from the dead earth in the pan from whence you raised the bank, and that at first, which is about an acre, is almost unprofitable. But afterwards, when that dead ground hath contracted a little new soil from the settling of the water, especially after land-floods, and lain dry a summer, whereby it will begin to graze, it will become like the rest of the pond, and put forth as good feed for fish as any other part. This may seem strange and new, but is a great truth, known to me from indubitable experience.

Then after one, two, or three years (for longer the pond must not stand full), when you come to restock, and so on in all like occasions, you may put four hundred carp, or three hundred carp, and eight hundred tench (if the water feeds them) into an acre, besides perches. It is incredible to those who have not seen it, as I have done, how carps thus ordered, by transplanting them every year or two, will grow. I affirm, that from six, they will grow to twelve and better the first, and to fifteen or sixteen the next year; and then they are most fit for a gentleman’s table ordinarily; for though greater are more ostentatious, yet these are the most sweet and best meat, as young flesh is commonly preferred to old.
