|Abstract||The oxygen consumption rates of three species of pleuronectids, the yellowtail flounder, Pleuronectes ferrugineus (Storer), the winter flounder, Pleuronectes americanus (Walbaum), and the American plaice, Hippoglossoides platessoides (Fabricius), were examined under simulated, land-based, aquaculture conditions. Routine oxygen consumption (ROC) rates for groups of each species were measured simultaneously using single-pass, flow-through respirometry. This study was conducted over three seasons at temperatures from 2 degrees C to 14 degrees C. An analysis of variance identified a significant interaction between temperature and species on the oxygen consumption rates of these flounder. The analysis indicated that at each temperature, ROC rates were significantly different among the three species (P < 0.05). A subsequent test of each species' ROC rate across the three temperatures indicated that both the yellowtail flounder and the winter flounder had significantly different ROC rates at each temperature experiment (P < 0.05). The ROC of yellowtail and winter flounder responded similarly to changes in experimental temperatures.|
