摘 要：
本文分析了河北省沿海小黄鱼、黄姑鱼、蓝点鲅、牙鲆、半滑舌鳎、鲈鱼、鯒鱼和孔鳐的饵料组成及其相互关系。主要结果有:(1)在饵料组成中,主要的饵料生物是日本鼓虾、脊尾褐虾、虾蛄、中国毛虾、黄鲫、日本鳀鱼、钝尖尾鰕虎鱼和尖尾鰕虎鱼等,这些主要饵料生物基本上都是群众渔业的重要捕捞对象;(2)种间存在不同程度的饵料竞争关系;(3)捕食与被捕食关系分别存在于鲈鱼与小黄鱼、鲈鱼与半滑舌鳎、鯒鱼与小黄鱼的种间。本文从饵料保障的角度,探讨了上述8个经济鱼种资源的恢复与其饵料生物资源的渔业捕捞之间的关系。

摘 要：
This paper analyses food compositions and mutual relationships of Pseudosciaena polyactis, Nibea albiflora, Sawara niphonia, Paralichthys olivaceus, Cynoglossus semilaevis, Laieolabrox japonicus, Platycephalus indicus and Raja porosa from coastal water off Hebei Province.Among the prey categories, the most important ones are Acetes chinensis, Alpheus japomicus, Squilla oratorio, Engraulis japonicus, Setipinua taty, Chaeturichthys stigmatias, Chaeturichthys hexanema, Caxcinoplax vestitus and Hemigrapsus penicilctus, etc.. According to the main prey categories, the food chains of these fishes can be divided into the following four patterns; 1) phytoplankton-zooplankton-fish,such as phytoplankton-Acetes chinensis-Nibea albifora;2) phytoplankton-zooplankton -fish-predatory fish, such as -Engraulis japonicus-Sawara nipknia; 3) benthon-benthonic shrimp-fish, such as benthon-Alpheus japonicus-Nibea aibiflora; 4) benthonbethonic shrimp-fish-predatory fish, such as benthon-Alphus japonicus-Chaeturichthys stigmatias-Pseudosciaena polyactis.There exists competition for food among the studied economic fish species.
