| Comments: | Largest coordinated spawning effort in June (50% partially spent gonads) and July (64.2% partially spent gonads). Mean monthly G.I. = 0.67 significantly correlated with mean water salinity levels (t=-2.07, df=11, alpha=0.05). Low incidence of parasitic infection by digenetic trematodes (3.33%) results in castration. | ||||||||||||
