摘要
以１９９０ ～１９９８ 年我国东海区的海洋渔业统计资料和渔业资源动态监测资料为依据，分析研究１９９５ ～１９９８ 年伏季休渔对东海区渔业生态效果的影响。结果表明，带鱼等主要经济鱼类的产卵群体得到了有效保护；经济幼鱼的渔获比例及其资源密度指数有所提高，幼鱼群体养护效果也较明显；渔获个体的生物学特征值具有转好的趋势；主要经济鱼类资源生物量明显增加；渔业资源的种间结构得到一定程度的改善；年渔获产量明显增加，单位捕捞努力量渔获量（ＣＰＵＥ） 有所提高。
Based on the marine fisheries statistical data and marine fisheries dynamic monitoring data in the East China Sea region from 1990 to 1998, the paper analyses the effect of summer close season in the last four years (1995～1998) on the marine fisheries ecology in the East China Sea region. The studied results show that some of the commercial spawning stocks have been effectively protected; the catch rate of commercial juveniles and the stock density indices have increased, while the larvae stocks have been conserved; the biological characteristics of the stocks caught have a tendency to improve; the biomass of the major commercial fish stocks have significantly risen; the interspecific structure of fishery resources has improved to a certain extent; the annual catch has showed a sharp rise with an increase of CPUE.
