Abstract

Juvenile white grunts were cultured in flow-through Juvenile white grunts (Haemulon plumeri) were cultured in flow-through tanks and fed three formulated diets and a control diet for ten weeks. The control tanks and fed three formulated diets and a control diet for ten weeks. The control diet was comorised of eround fish and fed a 43% orotein. diet was comprised of eround shrimp and sauid. Fish fed a 43% orotein. 10% moisture salmonid diet had signiticantly (P<0.05) lower growth rates (0.20 g/d. 0.76 %/d) and significantly higher feed conversion (12.4) than the fish fed the control diet (0.26 g/d, 0.92 %/d, 10.2). There were no significant differences in growth rates and feed conversion between fish fed the control diet and a 43% protein, 18% moisture. semi-moist salmonid diet or a 55% protein, 7% moisture marine finfish diet. There were no significant differences in condition factor between fish fed the control and formulated diets. Survival was 100% for all treatments. Although no diseases were observed and the fish responded well to handling. relatively low growth rates and poor feed conversion with all diets indicate that white grunts are not desirable for foodfish aquaculture
