| Body fluid ionic content of fishes varies with ambient. Variations in the plasmatic ionic concentration have also been related with sex or maturation cycle, once that reproduction modifies metabolic processes. In fishes, the gallbladder is an important osmoregulatory organ. So, the present work has been focused on the relation of plasmatic and biliar electrolytes with sex and maturation cycle, of the teleost fish Prochilodus scrofa at the resting and mature stages of gonadal cycle. The animals (28 males and 30 females) were collected at Cachoeira de Emas (Pirassununga, São Paulo) and they were fasted for three days before the experiments. Deteminations of Na+, K+, Mg++, and Ca++ were made by spectophotometry and Cl- by microtitulation. Comparisons of ionic... |
