Evaluation of various protein sources for Penaeus monodon postlarvae

Abstract

Penaeus monodon postlarvae with an average weight of 15.61 mg each were fed fresh brown mussel meat and artificial diets containing casein, shrimp meal, squid meal and Spirulina as protein sources at a daily rate of 20 per cent of their biomass for 10 days. Results indicate that squid meal is best for growth based on weight gain, diet conversion, and protein efficiency ratio. Fresh brown mussel meat was essentiallly comparable to shrimp meal for growth but was inferior based on protein efficiency ratio and survival rate. Both squid meal and shrimp meal appeared to be good protein sources for P. monodon postlarvae.
