渔情预报是渔业生产的关键环节,包括资源状况和渔期渔场预报。而研究渔场的成因主要考虑海洋鱼类内在生理因素要求的内因和制约鱼类行动的外界因素。外因诸因子很多,有些直接、有些则间接对渔场形成起作用。概括起来分四大类:水文(包括水系即海流、水温、潮汐、盐度、水色、水质和径流等),气象(包括风、气压、气温、降水等),地理(包括地形、地质、地貌等),生物(浮游、底栖、敌害 Prediction of fisheries is a key link in fishery production, including resource status and fisheries forecasts. The origin of the research fisheries mainly considers the internal factors that are required by the intrinsic physiological factors of marine fish and the external factors that restrict the fish actions. Many external factors, some direct, while indirectly indirectly on the formation of fisheries. To sum up, there are four major categories: hydrology (including water system, current, water temperature, tide, salinity, water color, water quality and runoff), weather (including wind pressure, temperature, precipitation, etc.) Etc.), creatures (planktonic, benthic, predatory)
