The objective of this work was to study the morphologic development and the swimming and feeding behaviors of piracanjuba larvae, Brycon orbignyanus Valenciennes (1849) (Characiformes, Characidae, Bryconinae), during the period from zero to 172 hours after hatching (standard length = 3.62 – 11.94 mm). The morphological analyses were accomplished by using a trinocular stereo microscope, while the behavioral analyses were performed through periodic observations. In 28 hours after hatching, the larvae (standard length = 6.25 ± 0.13 mm) showed the […]

The experiment was conducted in order to evaluate the effect of 3 diluents BTS+KCl – D1, BTS+2KCL – D2 and BTS+Sodium Citrate – D3) and three different times (hour 0, 72 hours and 144 hours) in Piracanjuba (Brycon orbignyanus) semen at 4°C. The assay aimed to test usefulness of BTS (Betsville Thawing Solution) diluent medium, added to Sodium citrate and Potassium clorate, in maintenance of spermatic immobility and of its conditions to conserve semen characteristics as spermatic motility rate and […]

The aim of this study was to determine the dietary protein requirement and associated energy to protein (E/P) ratio for “Piracanjuba”, Brycon orbignyanus, fingerlings. Casein-gelatin semipurified diets were formulated to contain six crude protein (CP) concentrations: 24, 26, 29, 32, 36 e 42% at one energy level, 3,000 kcal metabolizable energy (ME)/kg. These diets resulted in E/P ratios of 12.3, 11.6, 10.4, 9.2, 8.5 and 7.1 kcal ME/g CP, respectively. The protein, lipid and digestible carbohydrate sources were casein/gelatin, cod […]
