| 摘 要： | 根据2006年夏季、冬季和2007年春季、秋季在福建沿岸近海作业的底拖网渔业资源调查结果,对其中17种主要经济鱼类的渔业生物学进行了初步分析,并运用体长频率法估算了Von&Bertalanffv生长参数、总死亡系数、自然死亡系数、捕捞死亡系数和开发率.结果表明:大部分鱼类已呈现个体小型化.16种鱼的开发率过高,处于超额...

| Abstract: | On the basis of the bottom trawl fishery resources investigation in Fujian coastal waters in August 2006 to November 2007,17 major economic fish species samples were analyzed,and parameters such as Von Bertalanffy growth parameters,total mortality,natural mortality,fishing mortality and exploitation rates,were estimated by length based methods.The results showed that miniaturization occurred in most of the fishes,and the exploitation rates of 16 species were excessively high.Among those fishes,5 species whose rates ranged from 0.7 to 0.8,were in middle over exploitation;and the other 11 species whose rates ranged from 0.5 to 0.7 were in lower over exploitation.In order for sustainable utilization of fishery resources,effective protection and management measures should be taken. |
