渔情预报

东海北部秋汛灯围渔情预报的研究

Study on the Forecast of Fishing Conditions of Light Seining in Autumn Fishing Season in the Northern Part of the East China Sea

文中还讨论了南黄海大沙和吕泗渔场的性质特征，以期为蓝点马鲛渔情预报提供基础资料。

Additionally , the characteristics and functions of two important fishing grounds : Dasha and Lvsi in the Southern Yellow Sea are discussed for providing basic data for fishing forecast .

利用2010年生产统计数据，采用自然边界法将生产统计数据和栖息地指数均分为5个级别，对渔情预报模型进行了验证。

The 5 levels for both the HSI index and the products data are derived by using the natural boundary method and are used to verify the accuracy of the model .

调查表明，在海况正常的年景、幼鱼发生量指数（密度指数）与上层鱼渔获量呈正相关，可作为预测资源丰欠和夏秋汛渔情预报的一个主要指标。

The investigation shows that in ordinary years the juvenile fish emergence size ( biomass index ) is directly proportional to its catch which can be used to predict stock situation and as a major index of predicting summer and autumn emergence sizes .
