Water flow requirements related to oxygen consumption in juveniles of Oplegnathus insignis

In this study the oxygen consumption rate in four groups of Oplegnathus insignis was examined under three different water temperatures 13, 18 and 23°C. Average weight of each group of fish was 9.5, 198, 333 and 525 g respectively. Oxygen consumption was measured in a respirometer of 18.8 L capacity...
