Abstract:

A growth experiment was conducted to evaluate the dietary essentiality of vitamins for juvenile white shrimp, Penaeus indicus. Effects of deletion of individual vitamins [thiamine, riboflavin, pyridoxine, cyanocobalamine, pantothenic acid. folic acid, niacin, biotin, choline, inositol, ascorbic acid, vitamin A acetate, calciferol (vitamin D), alpha-tocopherol (vitamin E) and menadione (vitamin K)] from semi-purified diets on shrimp growth, survival and midgut gland morphology were examined in a seven week feeding trial. Growth rate was poorest for the control treatment without vitamin supplements, inositol, choline, pantothenic acid and alpha-tocopherol deficient diets. Shrimp fed diets deficient in niacin, choline, inositol, ascorbic acid and alpha-tocopherol showed poor survival. All treatments except the control diet supplemented with vitamins and the biotin and menadione deficient diets showed changes in the midgut cell profile. Detachment or destruction of the epithelial cells was observed in most cases but most severely in the control treatment without vitamin supplement, followed by the inositol, choline and ascorbic acid deficient diets.
