A large force of men are employed in keeping the troughs clean. All sediment and debris from the water is swept out of the troughs and all dead eggs are removed by means of a pipette. Both eggs and young fish are parasitized by certain bacteria and care must be taken to see that all infected individuals are removed to prevent spread of the infection. In order to feed the millious of fish at the Sisson Hatchery, it is necessary to maintain a kitchen where food is prepared. From six hundred to seven hundred pounds of this prepared food is fed to the fish every day during the rearing season. In order .to make this amount of food it takes about three hundiH'd pounds of meat. This is obtained from slaughter houses in San Francisco. The food is pre-. Fig. 37. A fish trap on the Klamath River at Copco, California. Thousands of fine large trout were obtained for spawning here. pared by taking such scraps of meat as beef heads, livers, lights, and the like, grinding them up, mixing them with corn or other meal, and clabbered milk, and cooking this into a sort of mush. The pond fish soon learn to know the man who feeds them, and they will follow him about from one side of a pond to the other. AVlien the food is thrown into the pond, there is a wild dash for it, and the water files in every direction. In addition to this food the pond fish often obtain insects which alight on the water, and not infrequently a trout can be seen "jumping" for such delectable morsels. A similar kind of food is prepared for both the trout and salmon fry. When the fry are old enough to care for themselves, they are placed in "; small ponds made especially for the small fish. As pond trout and salmon are somewhat eannil)alistic, it is necessary that. Please note that these image
