Health management in marine fish and shrimp hatcheries with special reference to immunostimulants (an overview)

Egyptian Government expresses efforts to provide aquaculture industry with high quality fish and to prevent diseases outbreak. The production of larvae and fry is still unpredictable for some species, owing to the lack of control of the microbiota in the rearing systems. Using conventional approaches such as the use of disinfectants and antimicrobial drugs, have had limited success in the prevention or cure of aquatic disease. Also, use of antibiotics does not constitute a sustainable solution, and may result in microflora imbalance for the larvae. Better means for disease prevention and control will be easy through the development of intensive aquaculture production systems. In order to prevent the proliferation and spread of opportunistic pathogens. Further progress upon an efficient microbial control, particularly in the production of larvae and during on-growth in required. Immunostimulants are currently known as alternative strategies to the use of antimicrobials in disease control and have already been proposed and applied successfully in aquaculture. This paper will focus on the use of immunostimulants as a health management tool to control diseases in marine fish and shrimp hatcheries.
