The long-term (1980−2018) data on the water temperature regime and associated synoptic processes in favorable and unfavorable years of the abundance formation and the pink salmon Oncorhynchus gorbuscha return to the rivers of the Sea of Japan coast in Primorskii krai have been analyzed. It is shown that low catches of Primorye pink salmon at the end of the past century were accompanied by negative temperature anomalies in the coastal waters and increasing catches during the first two decades of the new century were accompanied by positive temperatures anomalies. Pink salmon returns to rivers at the sea-water temperature 8.6−14.9°С, and values below 3.0–4.0°С are one of the reasons of redistribution of anadromous migratory flows of pink salmon in the Primorye subzone. The synoptic and hydrological situation at different intensity of pink salmon return is described using concrete examples. With a high frequency of cold air troughs typical for the first cold stage of the Far Eastern monsoon caused by the Okhotsk anticyclone, the pink salmon return was delayed and extremely high catches were recorded when the second (warm) stage of the summer monsoon strengthened due to spreading of the Hawaiian anticyclone in the Sea of Japan. The results may be used for short-term prediction of the dynamics of the Primorye pink salmon return.

关于丰度形成和粉红色鲑鱼Oncorhynchus gorbuscha有利和不利年份的水温和相关天气过程的长期（1980-2018）数据返回到日本海的河流在滨海边疆区的河流进行了分析。结果表明，在上个世纪末，滨海边疆区粉红鲑鱼的低捕获量伴随着沿海水域的负温度异常，而在新世纪的前二十年中，渔获量的增加伴随着正温度异常。粉红鲑鱼在海水温度为8.6-14.9°С时返回河流，而值低于3.0-4.0°С是在滨海边疆区重新分配粉红鲑鱼迁徙性流动的原因之一。通过具体实例描述了不同强度的粉红鲑鱼返回的天气和水文情况。由于鄂霍次克反气旋造成的远东季风初冷阶段的冷空气槽频率很高，由于夏威夷反气旋在日本海的蔓延，夏季季风的第二个（暖）阶段加强，粉红色鲑鱼的返回被延迟，并且记录到极高的捕获量。该结果可用于对滨海边疆区粉红鲑鱼返回动态的短期预测。
