Influence of diet on the feeding behavior, growth, and thermal resistance of postlarval Penaeus aztecus and P. setiferus.
MetadataShow full item record
Lab studies were conducted on the effects of diet on the food preference, survival, growth and temperature tolerance of two species of penaeid shrimps, Penaeus setiferus and P. aztecus. Both shrimp usually showed food preferences when given options. P. setiferus demonstrated stronger food preferences than the other species. Diets influenced survival, growth and temperature resistance of the shrimps. The effects of some diets differed markedly between species. Results indicated that initial diet preference, survival, growth, and resistance to high temperature are independent qualities of foods as indicated by these two species of shrimps.
