Study on Diagnosis Precaution and Control of Bacterial Diseases in Fish

Dr. Ramlal Paswan

Abstract: This study investigates the common bacterial diseases in fish, their causes, and the impact of environmental stresses. The paper also discusses various diagnostic methods and suggests control measures to prevent these diseases, with focus on Gram - negative organisms. The aim is to enhance fish health and aquaculture productivity. Bacteria are very common in the aquatic environment. Most bacterial disease agents are part of the normal flora of the water. They cause disease only when the fish are stressed due to poor environmental conditions, inadequate diet and poor husbandry techniques. Most bacterial infections are caused by Gram - negative organisms including the genera Aeromonas, Citrobacter, Edwardsiella, Flavobacterium, Pseudomonas, and Vibrio. Aeromonas is more commonly a pathogen in freshwater fish, whereas Vibrio usually affects marine fish. Streptococcus is a gram - positive genus that causes disease in ornamental fish. Many of these bacterial pathogens are ubiquitous in the aquatic environment. Fish diseases, in various forms have been tormenting the aqua culturists ever since man learned the art of fish husbandry. The stability of a fish population in particular habit is very often disrupted by various factors viz., disease, habitat destruction, depletion of resources or other application of environmental stressors. Fish is in a State of equilibrium with the environment and a change in the environment parameters beyond the tolerance limit disturbs the equilibrium resulting in stress response in fish and making it valuable to fish disease.
