摘    要:根据统计资料,利用剩余产量模型专家系统(CLIMPROD)对东海鲐鲹鱼类最大持续产量(MSY)作了评估分析。结果表明:东海鲐鲹鱼类合计分析时的MSY在34.5~44.2万吨之间,接种类分别评估时,鲐鱼的MSY为16.1万吨,蓝圆鲹为22.2万吨;按区域分析时,鲐鲹鱼东海北部群的MSY为12.5~13.2万吨,福建沿海群为20.1万吨。

关 键 词:东海  鲐鲹鱼  最大持续产量  剩余产量模型  专家系统

Abstract:Based on the statistical data, the Maximum Sustainable Yield(MSY) for the different stocks of chub mackerel and round scad in the East China Sea were estimated by the surplus production models fitting expert system (CLIMPROD). The result showed that the MSY for stock of combining the two speies for East China Sea was between 345 ~ 442 000 an tones. It was 125 ~ 132 000 tones for the northern area and 201 000 tones for the southerm. when estimated for stock of different species, the MSY was 161 000 tones for chub mackerel and 222 000 tones for round scad.
Keywords:East China Sea  chub mackerel and round scad  the Maximum Sustainable Yield (MSY)  the surplus production model  expert system
