Growth
Growth was measured biweekly for the 75g/kg extended salinity experiment (Figure 2B). Control and treatment diverged significantly in weight after two weeks at 75g/kg (week 4 weighing). By the end of the experiment, weight was not significantly greater in the 75g/kg treatment versus the end of acclimation (week 2 time point). Overall, mean weight increased by 37% from the original weight in the 75g/kg treatment over 12 weeks from 3.756 g/fish to 5.173 g/fish. In comparison, the control treatment increased by 214% of the original weight from 3.933 g/fish to 12.37 g/fish.
