The Jeollanam-do Academy of Oceans and Fisheries Science has initiated a study to investigate the cause of spondylolisthesis in eels, a common issue in eel farming that leads to slow growth and reduced product value. This condition is attributed to external shape abnormalities, and aquaculture farmers are experiencing economic losses as a result. The study will focus on the breeding environment, water quality management, and potential pathogen infections across 10 farms in seven counties. The findings will be used to develop preventive measures and improve aquaculture technology. Jeollanam-do, the largest eel production base in the country, accounts for 59% of the national production.
