Nitrogenous Excretion of Penaeus monodon Postlarvae Fed with Different Diets

摘要

This study is designed to determine ammonia and nitrite excretion by Penaeus monodon 25-30 day old postlarvae fed with different diets (artificial and natural). Shrimps were fed with Chaetoceros calcitrans (phytoplankton), chironomid larvae (benthos), Brachionus sp. (rotifer) and artificial diet. In the control treatment shrimps were not fed. The highest concentration of ammonia was excreted by shrimps fed with artificial diet and the lowest by that of control treatment.
