Supplemental Feeding of Hybrid Striped Bass Fry

Phase-l hybrid striped bass fry were fed trout pellets at 0,6.7, and 13.4 kg/haJday, in 7 culture ponds in 1986. Yield ranged from 45.6 to 239.7 kg/ha. Survival ranged from 11% to 70%. Five ponds in which fish were fed trout pellets had substantially greater yields of hybrid striped bass fingerlings than 1 pond in which fish were unfed. In 1987, two culture ponds in which fish were fed trout pellets at 13.4 kg/haJday from the time of initial stocking had significantly greater (P < 0.05) yields of hybrid striped bass fry than 2 ponds initially fed 18 days after stocking. Yields ranged from 0 to 86 kg/ha and survival ranged from 0% to 61%. Feed allotment and time of initial feeding of trout pellets affected production of hybrid striped bass.
