248 FISH HATCHERY MANAGEMENTThe amounts to feed would be:July l-8; 2.910i x 4,160: l2l pounds/dayJuly 9-16; 3.130i x 4,160:130 pounds/dayJuJy 17 24; 3.34% x 4,160:139 pounds/dayJuly 25-31; 3.S7lo x 4,160:149 pounds/dayUnder normal conditions, adjusting feeding revels four times during themonth should prevent over- or under-feeding. The advantage of thismethod is its simpliciry.Feeding Guides for Coolwater FishesFor many years, fish culture was classified into two major groups. .,coldwater"hatcheries cultured trout and salmon, and "warmwater" hatcheries culturedany fish not a salmonid. Muskellunge, northern pike, walleye, andyellow perch prefer temperatures warmer than those suited for trout, butcolder than those water temperatures most favorable for bass and catfish.The term "coolwater species" has gained general acceptance in referring tothis intermediate group.Pond culture traditionally has been used to rear coolwater species. Thismethod of extensive culture involves providing sufficient quantities ofmicro-organisms and plankton as natural foods through pond fertilizationprograms. If larger fingerlings are to be reared the fry are transferred, whenthey reach approximately 1.5 inches in length, to growing ponds whereminnows are provided for food. A major problem in extensive pond cultureis that the fish culturist is unable to control the food supply, diseases, orother factors. Many times it is extremely difficult to determine the healthand growth of fish in a pond.In recent years the intensive culture of coolwater fishes in tanks hasbeen successful. Zooplankton, primarily Daphnia, are cultured in ponds andeach day a supply is placed in the rearing tanks. Fish reared in tanks canbe observed readily and treated for parasites. Fish also can be graded tosize to minimize cannibalism and to provide an accurate inventory.Pennsylvania fisheries workers successfully fed a diet of 100% Daphnia tomuskellunge for up to 5 months with no significant mortality, but after thefish attained a length of approximately 2 inches the Daphnia diet did notappear adequate.Fisheries workers in Pennsylvania and Michigan have reared coolwaterfishes successfully on dry feed. The w-7 dry feed formulated by the unitedStates Fish and wildlife Service specifically for coolwater fishes hasgiven the best results. (See Appendix F for diet formulation.) Starter feed
