Updates on infectious diseases of largemouth bass: A major review

The largemouth bass (Micropterus salmoides) is native to North America and has now become a crucial economic species in aquaculture. With the rapid development of high-density intensive farming models, the continuous emergence and spread of diseases pose significant challenges to the sustainable development of largemouth bass aquaculture, including Micropterus salmoides rhabdovirus (MSRV), largemouth bass virus (LMBV), Nocardia spp. and Aeromonas spp. Here, we provide a comprehensive overview of the latest research progress on common diseases of largemouth bass, including pathogen isolation and identification, pathological characteristics, morphological features, epidemiological characteristics, pathogen-host interactions, detection and diagnosis, vaccines, and other control technologies. This information will enhance a more comprehensive understanding of the occurrence of diseases in largemouth bass, and provide insights into future research directions, facilitating more effective disease prevention and control. The collaborative progress among rapid detection technology, the interaction mechanism between pathogen and host, and prevention and control techniques will be the curial to achieving green prevention and control of largemouth bass disease and healthy aquaculture in future.
