山东南四湖鱼类研究

A PRELIMINARY SURVEY OF THE FOURSOUTHERN-LAKES OF SKANTUNG

一、前言微山、昭阳、独山、南阳四湖,俗称南四湖,位于鲁西南,是山东最大的内陆水体,也是最大的淡水渔区和重要的养殖区之一。鱼类种类繁多,产量丰富,自然条件和水生生物条件都很良好,因此发展渔业和养殖都很有前途。生产部门也很重视。据我们所知,1953年山东大学生物系部分师生及黄海水产实验所部分同志。

The Weishan-,Chaoyang-,Tushan- and Nanyang lakes are commonly called Nan-Sze-Hu(the Four-Southern-Lakes)of Shantung.They are the most important fresh water fishery grounds and the chief fish farms of Shan- tung as well.Their ichthyological fauna has not yet been studied.During the summer of 1957,and during the spring and autumn of 1959,the authors msde a systematic survey of the fish fauna of these lakes.Some of their ecological habits Were also considered. We find 70 species(including subspecies)of fishes in these lakes.They belong to 47 genea and 15 families.Of them 23 species and subspecies have not been reported in Shantung.They are namely:Salangichthys microdon, Atrilinea chenchiwei.Paraleucogobio notacanthus,Sarcocheilichthys lacustris, Saurogobio productus,Erythroculter dabryi,E.oxycephalus,Parapelicus nicholsi,P.argenteus,Toxabramis hoffman,T.swinhonis,Hemiculter kneri,Acanthorhodeus guichenoti,Acheilognathus chankaensis,Parasilurus mento,P.asotus,Pseudobagrus intermedius,Leiocassis crassirostris,Aoris henryi,Anguilla japoniea,Hyporhamphus intermdius,Hypselectris einctus and Rhinogobius leavelli. The most common economic fishes are:Canasius,Hemiculter,Erythroculter, Cyprinus,Parabramis,Ophiocephalus,Sinrpeica,etc. The yield of the Carasius is in the first order and both the Erythro- culter and the Hemiculter come next.
