Health Examination of Cultured Red Hybrid Tilapia from Setiu Marine Pond Farm Terengganu

A total of 26 tilapia fishes from Setiu Marine Pond, Terengganu were examined for parasites and bacteria (Streptococcus agalactiae) infection. Along with fish host sampling, physiochemical parameters of the fish pond were also being recorded. The fish were examine for ecto- and endo-parasites, followed by bacterial examination from obvious lesions and selected organs such as liver, heart and spleen. The main parasites that were recorded were protozoan parasites from the external part of the fishes. Only one helminth was found from the intestine of the fish. All fish were negative for S. agalactiae infection. The correlation between the prevalence in relation to size class and gender of fish were weak to moderate but not statistically significant. Overall, the fish cultured in the marine pond shows an excellent health condition, this might be related to the optimum physiochemical parameters recorded in the pond during the sampling period
