Tilapia diseases and management in river-based cage aquaculture in northern Thailand

This is the authors' abstract. We don't add key points for this paper.

A total of 662 farmers who rear tilapia in river-based cages in Northern Thailand were interviewed on their knowledge and perception on disease constraints and their control measures. Most farms (84%) had disease problems in the last two years. Exophthalmia ranked higher than other clinical signs. Most farmers noticed that the risk of disease problems was similar every month. Most (95%) believed that fish diseases were caused by bacterial pathogens. To treat perceived disease outbreaks, most farmers (96%) removed infected and dead fish and applied, usually inappropriately, antibiotics. As disease prevention through good management is better than treatment, farmers and fish disease experts could use these research findings as a tool to work together to develop better control strategies.
