Abstract:

This paper aims to highlight the effects of various concentrations of protein premixtures onthe growth in length and weight of adult specimens of ornamental fish Poecilia reticulata, bred incaptivity. Of this consideration, the experiment was set up with six groups: R1, R2, R3, TG, TP and TD,which were fed differently as follows: R1 with mixed fodder containing 30% CP (crude protein), ownrecipe; R2 with mixed fodder containing 30% GP, own recipe; R3 with mixed fodder containing 30%CP, own recipe; TG with Troco Grower fodder containing 43% CP; TP with Troco Prim fodder containing44% CP; TD with Tetra Discus fodder containing 48% CP. The research was conducted over a period ofthree months in which there have been followed the length and weight, to determine body indices(average increase of the weight gain, Fulton index and average weight ratio multiplier).
