北太平洋东部是指从东经175°至北美洲大陆海岸,由赤道向北,包括阿拉斯加湾,白令海东部广阔水域。这是世界上海洋生产力最高的区域。美洲北部沿岸(北纬36°～52°)处于温带季风气候,南部沿岸系亚热带信风气候。阿拉斯加寒流、加利福尼亚寒流、戴维道松表层暖流对这个区域的水文条件影响甚大。白令海东部和阿列乌特岛区鱼产丰富。有10多种有渔业价值的底层鱼类,有众多的哺乳类海兽、海鸟。底层鱼类生物量为1,900万吨,其中50%有捕捞价值。
The eastern part of the North Pacific refers to the coast of North American mainland from east longitude 175 ° northward from the equator, including the Gulf of Alaska and the vast waters of the eastern Bering Sea. This is the highest marine productivity in the world. The northern coast of the Americas (36 ° ~ 52 ° N latitude) is in a temperate monsoon climate, and the southern coast is subtropical. Alaska Cold, California Cold, and the Davidson Pine Surface Precipitation have a significant impact on the hydrological conditions in this area. The eastern part of the Bering Sea and Areiotto are rich in fish production. There are more than 10 kinds of bottom fish with fishery value, there are many mammalian sea animals and seabirds. The bottom fish biomass is 19 million tons, of which 50% have fishing value.
