Densidade de estocagem de juvenis de tambaqui durante a recria em tanques-rede

Abstract: O objetivo deste trabalho foi determinar a densidade de estocagem mais adequada para a fase de recria de juvenis de tambaqui (Colossoma macropomum) em tanque-rede. Foram utilizados 12 tanques-rede de 1 m³ cada, com peixes distribuídos nas densidades de 200, 300, 400 e 500 peixes/m³ em três repetições. Os peixes foram alimentados seis vezes por semana em três refeições diárias com ração comercial com 36% de proteína bruta, durante 60 dias. Foram analisados o crescimento em peso e em comprimento, o coeficiente d… Show more

“…Similarly, increase in erythrocyte concentration is related to a greater oxygen demand in stress conditions (BRAUN et al, 2010), whereas variation in total plasma protein is an indicator of osmotic imbalance (WEDEMEYER, 1996). The values for glucose, hematocrit, and plasma proteins obtained for tambatinga were similar to those for tambaqui (BRANDÃO et al, 2004;CHAGAS et al, 2005;2007).…”

“…The coefficient of variation (CV) of the standard length, which indicates heterogeneity in growth (PETIT et al, 2001), did not differ as a function of stocking density, as reported for tambaqui (BRANDÃO et al, 2004) values ranging from 9.54 to 19.91% after 60 days in the initial grow-out phase. Mortality was not influenced by stocking density and it was below those found for tambaqui during the initial grow-out phase in net pens (16.0-31.2%) (BRANDÃO et al, 2004) and in earthen ponds (50.94-52.42%) (SILVA et al, 2007b). Stocking density did not affect protein and energy retention rates, reflecting the efficient use of food nutrients by tambatinga juveniles.…”
