Evaluation of the Dietary Iron Requirement of Penaeus vannamei Academic Article uri icon


  • Two experiments were conducted to evaluate the dietary iron requirement of juvenile Penaeus vunnamei. Prior to initiation of 28 day (Experiment I) and 35 day (Experiment II) feeding trials, 1720dayold postlarvae were fed the basal diet lacking iron supplementation but containing 12 mg Fe/kg for seven days. After conditioning, juvenile shrimp (mean weight: 0.038 g Experiment I, 0.047 g Experiment II) were fed one of four diets supplemented with 0, 20, 40 or 80 mg Fe/kg from ferrous sulfate heptahydrate. Final weight gain of shrimp ranged from 1.03 to 1.28 g in Experiment I and 1.62 to 1.94 g in Experiment II. Although percent weight gain was in excess of 2700% in Experiment I and 3400% in Experiment II, there were no significant differences in growth or survival of shrimp fed the different levels of iron. Iron levels of the hepatopancreas and carapace increased linearly with dietary iron; however, there were no significant differences in the iron content of muscle tissue. Based on these results, the iron content of the basal diet appeared to satisfy physiological needs of the shrimp. Therefore, practical diets containing protein sources of animal origin which are rich in iron should not require iron supplementation. Copyright 1992, Wiley Blackwell. All rights reserved
