Msy tie the length , width convenient adjusting .

打结长度、宽度可以方便的进行调整。

Based on the theory of MSY ( Maximum Sustainable Yield ), a general optimal-stocking model was formulated .

进一步根据最大可持续产量理论构建了最适放养量模型。

Studies on resource change and MSY of Coilia mystus in the Yangtze River estuary

长江口凤鲚资源变动及最大持续产量研究

But , the pelagic fish catches were not attained the MSY in recent years .

中上层鱼类实际年渔获量至今尚未超过其最大可持续开发量。

Surplus production models are the classic methods to predict MSY , and are among the main theories and models in modern fish stock assessment and management .

剩余产量模型是预测最大可持续产量（MSY）的经典方法，也是现代渔业资源评估和管理的主要理论模型之一。

In addition , the maximum sustainable yield ( MSY ) and the optimum fishing effort ( FMSY ) were estimated on the basis of fishery statistics data by Schaefer model and Fox model .

渔捞业中的最佳经济产量是指能使持续的纯利润最大的产量，此时投入的捕捞努力量为最佳经济捕捞努力量。

A Thousand Marbles The production model produced a maximum sustainable yield ( MSY ) of 99.6 Kilo-MT and an optimum fishing effort ( f_opt ) of 114.76 Kilo-fishing days .

其结果是99.6千公吨的最大持续产量和114760作业日的最佳捕捞努力量。

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 ) .

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。
