TL;DR: The results show that A. crassipinnis depresses aerobic metabolic under hypoxia, with a decrease in glycolysis and oxidative enzyme activities, and increases its anaerobic metabolism with an increase in LDH activity coupled with a decreases in oxygen consumption, which indicates an increased in anaer aerobic capacity.

TL;DR: It is suggested that a wild population might be used as an important genetic resource to increase the genetic diversity of renewal stock lineages.

TL;DR: Nossos resultados revelaram alta capacidade anaerobica dos musculos esqueletico e cardiaco no periodo, quando as enzimas mostram niveis bastante inferiores (indicando supressao metabolica) em relacao aos animais ativos (dados obtidos na literatura).

TL;DR: It is suggested that the artificial populations of tambaqui, which contain animals originated from this funding population at Pentecostes, should be renewed with the introduction of a new group of individuals with genetic variability equivalent to the wild population.

TL;DR: The alterations observed for both species are strategies adopted by fishes to preserve oxygen supply to metabolizing tissues during exposure to hypoxia, and Metynnis hypsauchen showed to be more sensitive toHypoxia than Serrasalmus eigenmanni, since the first presented more significant alterations on these osmoregulatory and hematological parameters.
