While hematocrit fluctuated somewhat, there was no
significant trend to the change. Hematocrit averaged 30±1 in tilapia
following SW exposure and 31±1 in FW. Likewise, the fish's weights
between salinity treatments did not differ (p=0.4) and all experimental
fish were of the same age. Activity levels were recorded at
each time point throughout the respirometry experiments, though no
difference was noted between time points or treatments
