Phosphorus requirements of tambaqui juveniles
The aim of this study was to determine the requirement of digestible phosphorus in diets for juvenile tambaqui (Colossoma macropomum). 300 juveniles (26.4 ± 0.68 g) were used in a completely randomized design, consisting of six treatments with five replicates and 10 fish per experimental unit. The treatments consisted of six isoprotein, isonitrogenous,

Different extenders solutions for tambaqui semen cooling [PDF]
Abstract: The objective of this work was to evaluate the efficiency of extenders solutions in tambaqui (Colossoma macropomum) semen cooling at 6°C. The treatments consisted of semen dilutions with three extenders - BTS, HBSS, and ACP-104 -, and a control with undiluted semen. Cooled semen was evaluated by 24, 48, 72, 96, and 120 hours.

Spectrophotometric method for determination of Colossoma macropomum (tambaqui) sperm concentration
Abstract To assist the reproductive management of tambaqui (Colossoma macropomum) males in laboratory and commercial fish farming, a linear regression model was obtained from concentration curves using the spectrophotometric method. Twenty-two tambaqui males with an average age of three years old were selected and divided into two groups containing 11 ...
