摘要
本文通过对1977-2001年黄鳍马面鲀产量及粤、闽、浙、桂四省区捕捞努力量等统计资料,运用剩余产量模型分析,结果如下:(1)Schaefer模型:Y=8.06028f- 1.0394E-5f2,MSY=15.63万吨;(2)Fox模型:Y/f=9.4387e-2.60E-7f,MSY=13.37万吨。我国目前对黄鳍马面鲀的捕捞产量偏高,其产量应控制在16万吨左右。
Based on the capture of Navodon tessellates and fishing effort of Guangdong, Fujian, Zhejiang, and Guangxi provinces of China,surplus yield model was applied to assess the MSY of it. The results are as follows: (1) Schaefer model:Y=8.06028f- 1.0394E-5f2,MSY is 156 thousand and three hundreds tons; (1) Fox model:Y/f=9.4387e-2.60E-7f,MSY is 133 thousand and seven hundreds tons. The capture of Navodon tessellates in China is somewhat too high, and be controlled under 160 thousand tons maybe suitable.
