Bacterial diseases in the marine ornamental fish and its control

Production of colorful fishes for the aquarium trade is a rapidly growing sector of the aquaculture industry. In recent years, India is making rapid strides in marine ornamental fish trade through hatchery culture practices. Fish health management is a term used in aquaculture to describe management practices which are designed to prevent fish disease. In marine fish hatcheries, the indiscriminate use of antibiotics in prophylactic treatment has led to the development of the resistant strains and the need to switch over to other antibiotics. Mangroves have been a source for several bioactive compounds and used in folklore medicines. Extracts of mangrove species have proven activity against human, animal and plant pathogens. In this connection, the present research work has been carried out and found the efficiency of mangrove leaves towards the control measures of bacterial diseases in marine ornamental fishes.
