Effect of Stocking Density on Production of Advanced Juvenile Hybrid Striped Bass

Two nursery trials were conducted in 0.I-ha ponds to examine effects of density on production of juvenile reciprocal cross hybrid striped bass (female Marone chrysops x male M. saxatilis). In 1986, 1.4-g hybrids were stocked at 5,000, 10,000 and 20,000 fishlha. In 1987, 1.7-g hybrids were stocked at 12,500, 25,000, and 37,500 fishlha. During the studies, the fish were fed a commercial trout feed (38% protein) several times per day. Aeration and water exchange were provided to maintain satisfactory oxygen levels. After approximately 280 days, fish were harvested. At harvest fish ranged from...


Spawning and Grow-out Trials with Red Drum in South Carolina

Increasing interest in the farming of red drum (Sciaenops ocellatus) has resulted in research and development activities with this species at the Waddell Mariculture Center in South Carolina. Red drum adults were captured from tidal impoundments and held in ponds until being moved to tanks for spawning during their natural reproductive season. Three females averaging 11 kg spawned 9 million eggs, 50% of which hatched. The fry were reared to fingerlings in fertilized ponds. Survival of fry to fingerlings was 24%. Survival of fingerlings through their first winter was 57%. Simultaneously,...
