Abstract According to the production data of double-vessel bag seine fisheries from April to June, 2019, we analyzed the fish composition and distribution characteristics of by-catch of double-vessel bag seine. The results showed that the double-vessel bag seine along the coast of Zhejiang mainly caught juvenile Cape anchovy Engraulis japonicus, and caught 25 species of by-catch fish belonging to 7 orders and 19 families. The average body weight of blue mackerel Scomber japonicus was 1.38 g, with dominant fork length of 21—50 mm. The average body weight of the marbled rockfish Sebastiscus marmoratus was 0.45 g, with the dominant fork length of 21—30 mm. The average body weight of scaled sardine Sardinella zunasi was 0.52 g, with the dominant fork length of 21—50 mm. The China anchovy Stolephorus chinensis had average body weight of 2.12 g, with the dominant fork length of 61—70 mm. The average body weight of amberfish Decapterus maruadsi was 0.45 g, with the dominant fork length of 10—40 mm. The average body weight of Atlatic cutlassfish Trichiurus lepturus was 0.74 g, with the dominant anal length of 21—50 mm. The average body weight of butterfish Pampus argenteus was 1.84 g, with the dominant fork length of 31—70 mm. By-catch blue macherel, marbled rockfish, scaled sardine, China anchovy, amberfish, Atlatic cutlassfish, and butterfish were general species. The average relative catch densities of S. japonicus, S. zunasi, T. lepturus, S. chinensis and P. argenteus were 2.46×103 ind./h, 0.80×103 ind./h, 1.07×103 ind./h, 1.48×103 ind./h, and 1.18×103 ind./h, which were mainly distributed in the coastal waters of southern and central Zhejiang. The average relative catch density of S. marmoratus was 4.54×103 ind./h, which was mainly distributed in the coastal islands and reefs in southern Zhejiang. The average relative catch density of amberfish was 1.32×104 ind./h, which was mainly distributed in the central and northern waters of Zhejiang Province. The findings can provide reference for improving the management of double-vessel bag seine fishing.
