Annual report of the Commissioners of Fisheries, Game and Forests of the State of New York . hered in the spring, or even the pupa cases, and placed in a bucket of water andcarried to the stream or pond it is desired to stock.

Thecases are so abundant that when found it is an easy matter to collect them by thethousands if desired for transplanting. I imagine the eggs can be transplanted assuccessfully as the worms. The fish eat cases and all when they feed on the wormsin the cases, as they have no means of extracting them. All the fish food thus far referred to constitutes more particularly the food of fishesafter they have grown beyond the fry stage, although at some period of their existenceall of the food may serve to feed very young fish. There are smaller Crustacea thanthe crayfish or shrimp which swarm in the waters of ponds, lakes and streams, andwhich serve to feed young fish when they begin to take food through the mouth afterthe umbilical sac is Fig. 10. Cyclops Fig. 10 is one of these Crustacea, the Cyclops, and I regret that it is a very crudefigure of a male. The female has two attachments near the tail on either side whichare the egg sacs, and are easily distinguishable on close inspection. FISHERIES, GAME AND FORESTS. I I I The entomostraca are minute crustaceans, but the Cyclops has been greatlyenlarged, that it may be more easily identified. A single entomostraca, either ofthis specie or the one next described, is so small that it requires good eyes todistinguish it in the water, but a mass of some species of entomostraca in the waterin the spring and summer has an appearance not unlike blood. Small as thesecrustaceans are, a species of copepoda, to which order the Cyclops belongs, formsmuch of the food of whales. Fig. 11 is another crustacean, Daphnia pulex.
