黄吻棱鳀[Thrissa Vitirostris(Gilchrist et Thompson)],赤鼻棱鳀[T.kammalensis(Bleeker)]和康氏小公鱼[Stolephorus commersonii(Lacepede)]均为我国沿海常见的小型鱼类,是罗源湾定置网的主要渔获对象。有关上述3种鳀科鱼类生物学研究尚少,仅见陈大刚对黄渤海的赤鼻棱鳀、郑小衍和洪幼环对闽南台湾浅滩渔场的黄吻棱鳀和赤鼻棱鳀、陈清潮等对粤东沿岸的康氏小公鱼有过研究。本文对罗源湾的上述3种鱼类的食性进行分析,阐明它们的食性以及它们在罗源湾能流途径中所处的位置。 Thrissa Vitirostris (Gilchrist et Thompson)], T. kammalensis (Bleeker), and Stolephorus commersonii (Lacepede) are all common small-sized fish along the coast of China. Bay source of the main fishing network fishing target. About the three species of clam fish biology is still small, only to see Chen Dagang on the Yellow Sea and the Bohai Sea Rhodospirillum, Zheng Xiaoyan and Hong Youhuan Taiwanese fisheries in Taiwan shallow yellow snout ridge and red nose ridge ridge, Chen Qingchao on the eastern coast of Hong Small male fish has been studied. This paper analyzes the feeding habits of these three species of fish in Luoyuan Bay to illustrate their feeding habits and their location in the energy flow path of Luoyuan Bay.
