From January 15 to April 30,2024,a study was conducted in Jiangsu Province to investigate the catch of eel fry and analyze the composition of the eel fry net catch.The findings revealed that the net captured 51 species of fish,comprising 5 cephalopod species,14 shrimp species,4 crab species,and 28 fish species,which belong to 43 genera,31 families,and 16 orders.The relative importance index and diversity analysis of the bycatch indicated that the(Fenneropenaeus chinensis)and the Geocarcus longipes shrimp were the dominant species,with the Chinese hairy shrimp being particularly prevalent in March.Among the species caught,the Chinese shrimp had the highest damage rate in terms of tail numbers,while anchovy larvae exhibited the highest damage rate in March.It is recommended that the special fishing plan for eel fry be refined,fishing intensity be managed scientifically and reasonably,supervision and enforcement be strengthened,eel fry fishing standards be imple-mented in an orderly fashion,the selectivity of net gear be enhanced,and the use of environmentally friendly net gear be promoted.
