Research Article: Bacterial pathogens identification in farmed barramundi (Lates calcarifer) at Bushehr and Hormozgan province, Iran
چکیده:   (390 مشاهده)
The Asian sea bass (Lates calcarifer), also known as barramundi, is a species of great importance in Iran’s aquaculture industry. This fish has been farmed for many years to fulfill the rising domestic demand for fresh seafood and to promote exports. However, bacterial diseases and infections pose a significant threat to the growth of this popular species, leading to substantial losses. This study aimed to investigate bacterial contamination in barramundi at coastal cage farms located in the Bushehr and Hormozgan provinces of Iran, as well as to identify the signs and lesions resulting from these infections. According to the criteria for bacterial infection, 30 fish samples were collected from farms. Necropsies were performed on the collected fish, followed by bacteriological analysis and genotyping using 16S rRNA sequencing. The bacteriological results revealed five bacterial strains, confirmed through agent isolation, biochemical profiling, and 16S rRNA sequence verification. The identified isolates comprised Streptococcus iniae strain SB1 (60%), Streptococcus agalactiae strain 20 (70%), Shewanella algae strain 16 (60%), and Vibrio species such as V. azureus strain N3 (86%) and V. harveyi strain N4 (90%). The identification of bacterial species is crucial for resolving health issues and reducing mortality in farmed barramundi. This study comprehensively identified bacterial pathogens impacting barramundi in Iran. The findings, along with the detection methods and bacterial genotyping techniques used, offer practical insights for future research in this area. Additionally, this study increases awareness among researchers, farmers, and clinicians, facilitating the adoption of effective management strategies in aquaculture practices.
