Abstract

Juvenile prawn Macrobrachium carcinus were fed two different diets: restaurant by-products (diet 1) and fish and vegetable market by-products (die! 1I). These diets were evaluated by proximal analysis, assimilation efficiency and the factor conversion rate (FCR). Diet 1 registered a higher efficiency, but there was no difference in the growth rateo The growth mean (G. L.) for tbree months was 0.254 ± 0.13 cm (diet 1) and 0.191 ± 0.1 cm (diet lI). The conversion rate was good for both, suggesting that 6 to 7 kg of food are needed to obtain 1 kg of prawn. Survival was 76 % and 100 % for diets 1 and n, respectively.
