南沙群岛西南部陆架海区主要经济鱼类渔业生物学的初步研究

A PRELIMINARY STUDY ON FISHERIES BIOLOGY OF MAIN COMMERCIAL FISHES IN THE CONTINENTAL SHELF TO THE SOUTHWEST OF NANSHA ISLANDS

本文根据１９９２－１９９３年南沙群岛西南部陆架海区底拖网渔业资源调查资料，分析了 １７种主要经济鱼类的渔业生物学特性，并应用体长方法估计了 ｖｏｎ Ｂｅｒｔａｌａｎｆｆｙ生长参数（Ｌ和Ｋ）、总死亡系数、自然死亡系数、捕捞死亡系数和开发率，讨论了资源的开发状况。

On a basis of demersal trawl fishery resources investigation in the continental shelf to the southwest of Nansha Islands in 1992-1993. This paper described the fishery biological characteristics of seventeen species of major commercial fishes. von Bertalanffy growth parameters (L and K), total mortality, natural mortality, fishing mortality and exploitation rates were estimated by using length - based methods. the exploitive status of the stocks included were discussed.
