Abstract: |
According to the data selected from bottom trawl fishery resource monitoring in the East China Sea from 1997 to 2000, the species composition and seasonal variation of small-sized fish were analysed. The results indicated that there were 98 species of small-sized fish in the East China Sea, the dominant species were lanternbelly(Acropoma japonicum), gaper(Champsodon capensis), Japanese anchovy(Engraulis japonicus), skinnycheek lanternfish(Benthosema pterotum), cardinal fish(Apogon lineatus), blackmouth splitfin(Synagrops japonicus), scaly hairfin anchovy(Setipinna taty), macclelland’s codlet(Bregmaceros macclellandi). Every season the species and occurrence frequency of small-sized fish changed a little,but the abundances and biomasses changed greatly. |
