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。
In this paper, from the research on the growth of Crested Alice, the edible and reproductive biology in each period, this paper made a deep discussion on the status and function of Crested Alice in Taihu Lake fishery resources. The author believes that in the past simply to use as a ferocious dearth of fish resources in Taihu Lake, killing fish without restraint, is causing the present Taihu Lake fish composition and the economic value of the catch decreased one.
