Rearing Lake Whitefish to Fingerling Size

Abstract
Lake whitefish (Coregonus clupeaformis) were reared on Zooplankton after hatching until most fish readily accepted a dry diet by 13 weeks, when they averaged 40 mm (total length). Survival to 24 weeks was 4.0% and the fish then averaged 115.3 mm. The high mortality between 5 and 10 weeks was attributed to insufficient Zooplankton caused by the high density of fry in the rearing containers; gill disease and fin rot also contributed to mortality.
