Sustained swimming improves fish dietary nutrient assimilation efficiency and body composition of juvenile Brycon amazonicus Scientia Agricola
Arbeláez-Rojas,Gustavo Alberto; Moraes,Gilberto.
ABSTRACT Sustained swimming (SS) usually promotes beneficial effects in growth and feed conversion of fishes. Although feed efficiency is improves at moderate water velocity, more information is required to determine the contributions of this factor on growth and body composition. Body composition and efficiency responses to the use of nutrients were determined in juvenile matrinxa Brycon amazonicus (Spix and Agassiz, 1829) fed with two dietary amounts of protein, 28 or 38% of crude protein (CP), and subjected to sustained swimming at a constant speed of 1.5 body lengths s−1 (BL s−1) or let to free swimming. The fish body composition under SS and fed with 28% of dietary protein showed 22% of increased in bulk protein and a 26% of decrease in water content...
