Treatment of gill fluke disease in hybrid grouper

"Hybrid grouper is a popular marine culture fish in Sabah, Malaysia. However, the production is limited. One of the factors was due to the gill fluke occur in fish farms. Monogenean parasite was suspected as the main cause of high mortality of hybrid grouper in the fish farm. The present study...
