| Abstract: | The results of food analysis showed that the Loligo beka is benthonivorous, and feeds mainly on benthos such as Crangon affinis (28. 3% in its food composition), Leptochela gracilis (11. 6% ), Eualus sinensis (4.7% ),Cratosqualla oratoria (4. 7% ), Upogebia wuhsiewenii (4. 6% ) and Pagurus pectinatus (4.6% ), which occupied 64. 3% in its food composition; as well as it feeds some necton (33. 7% ), and is the natural enemy for the juveniles of Pseudosciaena polyactis; The Sepielle maindroni is nektonivorous, and feeds mainly on fishes (especially on juveniles of P. polyactis), which occupied 81. 9% in its food composition. It is also the important natural enemy of P. polyactis (31. 1%); The Sepiola birostrata is benthonivorous and feeds mainly on Leptochela gracilis, Eualus sinensis and other young shrimps, which occupied 52. 2% in its food composition. |
