T pense que les la plupart des aliments sains pour les alevins de truite très ^ les jeunes seront jugés les plus jeunes et encore plus petits alevins de poissons frayant au printemps, et je me risque à prédire que le moment viendra où cette nourriture naturelle sera généralement utilisés lorsque cela est possible. La perchaude (PfnaJ/avesa'ns), qui fraie en avril, est une admirable de poisson en vue, comme il est très abondante, et ses œufs sont nombreux, faciles à obtenir, et très facile à impreg- nate et hatch

. Domesticated trout [microform] : how to breed and grow them. Fish culture; Trout; Pisciculture; Truite. APPENDIX IX. PERCH HATCHING. h) W. T THINK that the most wholesome food for very ^ young trout fry will be found to be the still smaller and younger fry of spring-spawning fish, and I venture to predict that the time will come when this natural food will be generally used when practicable. The Yellow Perch (PfnaJ/avesa'ns), which spawns in April, is an admirable fish for the purpose, as it is very abundant, and its eggs are numerous, easily obtained, and very easy to impreg- nate and hatch. With this end in view, the following notes are given in regard to hatching perch eggs. It is the easiest and simplest thing in the world to manipulate perch and take their eggs artificially, and hatch them. I have taken millions in that way, and have hatched hundreds of thousands of them. Indeed, after my first experience, during the year 1868, I found it vastly easier, and had better luck, than with the salmon family. It is not only very easy to take perch eggs by hand, but you can generally impregnate the whole of them, or very nearly the whole of them. If any one would like to see how easy it is, let him take a good-sized milk-pan, nearly full of water, and having found a ripe pair of golden perch, —this is easy enough, I have found hundreds just ripe, — let him impregnate the water well with the milt of the male, and proceed as follows with the female • — Hold the fish just over the edge of the pan, so as to let the exteri'or end of the roe rest, as it comes out, on the further edge of the pan. It will stick in a moment. Then L'JftVi.
