Freshwater and marine water fish diseases: A review

Abstract

Pathogenic microorganisms may induce infection by numerous stress factors, such as insufficient physicochemical and microbial content of culture water, poor nutritional status and high stocking density. Acute levels of contaminants and suspended solids in seed fish and adults can directly cause anomalies and mortality. In terms of elevated morbidity and mortality, decreased development and expanded spending on the use of chemicals as prevention and control steps, multiple opportunistic bacterial pathogens and parasites cause catastrophic losses in the fish industry. Fish disease prevention is as is known, of paramount importance in terms of sustainable aquaculture development.
