Dietary requirements of copper, manganese, and zinc were investigated for the Indian white shrimp Penaeus indicus using purified diets. Feeding trials conducted on
shrimp with an average weight of 70 mg for 45 days have shown that without supplemented copper, the diet produced higher growth (p > 0.05). However, the diet with 22.7
mg% copper gave the lowest feed conversion ratio (FCR) of 2.14 (P > 0.05) and higher
survival rate (81.3%). Copper content in whole body of shrimp increased with dietary
copper. Shrimp fed with diets having different levels of manganese grew better on the
diet (control) that had 0.21 mg of manganese per 100 g. Higher levels of dietary manganese suppressed growth (P > 0.05). However, food conversion ratio (FCR) and survival
rate improved when the diet contained 1.9 to 2.6 mg% manganese. In the case of zinc,
the growth of shrimp improved with dietary zinc up to 23.6 mg% and declined thereafter
(p > 0.05). However, the diet with 38.6 mg% zinc produced low FCR (p > 0.05). Zinc
concentration in shrimp body increased with the dietary levels of the element, though the
body ash showed a decreasing trend.
