Abstract

The present study evaluates the potential of the house fly larvae (Musca domestica) as a protein alternative in the feeding of prawns (Macrobrachium tenellum). Three feeds were used to evaluate the following response variables: growth rate, survival rate, feed conversion ratio and protein efficiency ratio. The first feed (T₁) was a meal obtained after process fly larvae produced in a controlled environment, the second one (T₂) was an experimental formulated feed based on the meal obtained, and the third one (T₃) was a commercial feed. The feeds were supplied to 216 individuals of M. tenellum, with an initial weight of 0.897 ± 0.007 g for a 60 days period. After 30 days, the experiment results showed that T₂ presented significant differences in promoting the growth and survival of M. tenellum over the other treatments. However, at the conclusion of the study, an improvement was observed for T₃ culminating with no significant differences for T₂, which suggests that the domestic fly larvae possess nutritional characteristics that make viable the incorporation as a protein source in the formulation of a feed for Macrobrachium tellenum.
