1981-2005年期间，分析了日本海中上层优势鱼类-毛罗鱼的卵丰度，作为产卵-成鱼丰度的指标。在1988/1989年前后，卵丰度发生了重大变化，1981-1988年出现负异常，1989年开始出现正异常。大约在同一时间（1986/1987），对马海流从寒冷转向温暖的条件。两年后，环境指数与卵丰度呈正相关。我们的结果表明，M.它受气候变化的影响，可以作为一个指示物种。
Egg abundance of Maurolicus japonicus, a dominant mesopelagic fish in the Japan Sea, was analyzed during 1981-2005 as an index of the spawning-adult abundance. There was a major change in egg abundance around 1988/1989, with negative anomalies occurring during 1981-1988 and positive anomalies occurring from 1989. At about the same time (1986/1987), the Tsushima Current shifted from cold to warm conditions. Environmental indices were found to be positively correlated with egg abundance two years later. Our results suggest that the abundance of M. japonicus is affected by climatic regime shifts, and that it could be used as an indicator species.
