摘要
通过对黑鲷、漠斑牙鲆及暗纹东方鲀3种肉食性鱼类捕食脊尾白虾的行为观察。结果发现,3种肉食性鱼捕食脊尾白虾的强度排列依次为黑鲷>暗纹东方鲀>漠斑牙鲆。脊尾白虾最主要的防御方式为尾扇拨水向后弹开。
To study the characteristic behaviors of preying on the shrimp (Exopalaemon carinicauda Holthuis),black sea bream ( Sparus macrocephalus ) , Takifugu obscurus and Parallchthys lethostigma were compared with each others. The results indicate that the black sea bream (Sparus macrocephalus ) is the highest, the Parallchthys lethostigrna is the lowest based of predation intensity. The shirmp are flicking backward to evade attacks of predators.
