| 摘 要： | 本文从研究翘嘴红鲌的生长、各个时期的食性和繁殖生物学出发,对于翘嘴红鲌在太湖渔业资源中的地位及作用作了比较深入的探讨。作者认为,过去把翘嘴红鲌简单地当作有害于太湖鱼类资源的凶猛鱼类而不加节制地加以捕杀,是造成目前太湖鱼类组成小型化和渔获物经济价值下降的原因之一。因此提出了保护和增殖翘嘴红鲌的主张,并且具体地提出了有关翘嘴红鲌的起捕规格、禁渔期和禁渔区、限制有害渔具、实行人工放流和保护水域环境等一系列建议。

| Abstract: | The age and growth, food and feeding habits ixi different stages and the biology of reproduction of the whitefish in Tai Hu Lake has been studied in 1980-1981..Particularly the present statQ of whitefish in the fishery of Tai Hu Lake was empha-tically investigated. So far, the whitefish has been thought to be a voracious fish and harmful to the fishery resources of Tai Hu Lake. So that the population had been seriously damaged by overfishing. Consequently, accompanied with maladjustment the composition of fish in the lags gradually become small and trashy, most of the valuable fish diminished and the undesirable populations explosively developed. After analysing the prey-predator relationship between the lake anchovies (Coilia ectenes taihuenasis Yuan et Lin, and C. brachygnathus Krey. et Papp.) and the whitefish,the necessity for protecting and enhancizlg of the whitefish in Tai Hu Lake is propo-sed, and the dotails about the catehahle site, prohibitions on fishing season, fishing-ground and fishing gears, also the releasing of fingerlings to the lake and the protection of environment are all suggested. |
