摘要： 在研究东山岛西埔湾港养生物资源及其开发现状的基础上,指出资源种类逐年减少,年渔获量急剧下降,渔获个体趋于小型化,资源已明显衰退。作者认为过度捕捞是导致西埔湾总渔获量下降的最主要因素。为了保护资源和提高渔获量,必须控制捕捞力量,改善港养环境条件,并采取季节性开闸纳苗和放流增殖措施。

Abstract: Altogether, 132 species of fishes and 42 species of invertebrates were collected in the Xipu Bay (a semi-closed bay with a seawall) of Dongshan Island, Fujian Province, during the period from September 1989 to October 1990. Among these species, Clupanodon punctatus, Spa-rus latus, Mugil cephalus, Liza carinatus, Lateolabrax japonicus, Siganus fuscescens, Penaeus penicillatus, P. semisulcalus, Metapenaeus ensis, Ponunus pelagicus, Scylla serrata and Muscu-lus senhousei are the most important in yield or value of catch. Based on the researches on the present status of organism resources and the exploitation in the Xipu Bay, it is found that the resource species decreased, the catch dropped sharply and the individual size became smaller annually. The organism resources in the bay have declined obviously. The authors consider that the decrease in total catch is mainly caused by overfishing. In order to protect the organism resources and raise the catch, it is necessary to limit fishing activities and improve environmental conditions. Furthermore, opening the sluice gates seasonally to bring fry into the bay and the measure of ranching and farming should be adopted.

Key words: mariculture, organism resources, overfishing, ranching and farming
