Their Production, Appropriate Employment,' and Cost. The Production Of Yearlings from fry is a very simple matter. The fry are merely placed in suitable ponds and fed sparingly but continuously for all daylight hours from May until August. The food is cheap, consisting at first of raw liver, and afterwards of finely chopped horseflesh. The ponds must be suitably constructed (see page 62) and the earth renewed each season. Gulls and herons require shooting and trapping, or a dog may be trained to herd the ponds and scare off the water-fowl. One collie at Howietoun is unceasing in this watch, but in spite of dogs, traps, and guns, the gulls do take a very serious toll of the fry when first placed in the yearling ponds. One hundred thousand (nominal) three-month-old fry require four ponds, each 100 feet long by 22 wide at top by 5 feet 6 in depth, and should make from 30,000 to 40,000 good saleable yearlings and a few thousand undersized fish. The ponds must be dried for one month, and must stand full of water for at least three weeks before stocking, five weeks is better, so that the water becomes charged with animal life. The most difficult time for the fish-culturist is thefew days immediately following the plantation of three-month-old fry. Numbers weaken through starvation before they know the feeding spoons, but when there is ten days supply of natural food in the pond, no fry weaken through starvation, and five boxes of fry will produce the same number of yearlings that, under less favourable circumstances, six boxes would produce. Appropriate Employment Of Yearlings.— Yearlings fit all uses, they travel better than any other size. They bear out Mr. Guy's description of them in the Howietoun Fishery Price List :-- ' Yearlings are, par excellence, the siz...
