Abstract

Fish is the most indispensable source of proteins for individuals and have high nutritional value. On the other hand, the fish culturing raised issues of fish health due to close contact between the aquatic environment and the fish pathogens. So, the aim of the current study was to identify the bacterial pathogens and screen the injured Rainbow trout rearing in different trout hatcheries run under fisheries department of the government of Azad Jammu and Kashmir, Pakistan. Seven bacterial pathogens such as Shigella flexneri, Enterobacter amnigenus, Salmonella Typhimurium, Serratia odorifera, Pseudomonas aeruginosa, Streptococcus pyogenes, and Bacillus cereus were isolated and identified. Results revealed that the injury of fish specimens was due to overcrowding. Instead of rainbow coloration, specimens have darker black in color. The water of ponds was not clean and clear and such conditions was because of the greater quantity of feed thrown in the water. It was concluded that poor hygienic water condition and overloading allowed the opportunistic bacterial contaminations to succeed which cause a serious threat to hatcheries.

O peixe é a fonte mais indispensável de proteínas para os individuos e tem alto valor nutricional. Por outro lado, a cultura dos peixes levantou questöes sobre a saúde dos peixes devido ao próximo contato entre o ambiente aquático e os agentes patogénicos desses peixes. Assim, o objetivo do presente estudo foi identificar os patógenos bacterianos e rastrear a criaçâo da truta arco-íris que apresentou lesöes em diferentes incubadoras de trutas, com supervisäo do departamento de pesca do governo de Azad Jammu e Caxemira, Paquistäo. Sete patógenos bacterianos foram isolados e identificados, tais como: Shigella flexneri, Enterobacter amnigenus, Salmonella typhimurium, Serratia odorifera, Pseudomonas aeruginosa, Streptococcus pyogenes e Bacillus cereus. Os resultados revelaram que a lesao de espécimes de peixes foi devido a superlotaçao. Em vez da coloraçao do arco-íris, os espécimes tiveram uma coloraçao preta mais escura. A água das lagoas nao era limpa e nem clara, e tais condiçöes ocorreram devido a maior quantidade de alimento lançada na água. Concluiu-se que a precária condiçao higiénica da água e também a sobrecarga permitiram que as contaminaçöes bacterianas oportunistas fossem bem-sucedidas, causando séria ameaça as incubadoras.
