Survival was significantly greater (P < 0.05) in the low salinity tanks (95 ± 1.83%) than the high salinity tanks (76 ± 4.52%) when averaged across both density regimes. Density treatments had no significant effect on survival (P > 0.05), averaging 83 ± 5.59% and 88 ± 3.35% for low and high density treatments respectively (Table 6).
