鱼类专家称，造成大量沙丁鱼搁浅的原因是水温变化导致的。海水温度每天变化很大，下午相对 还算温暖，但是到了夜间温度急剧下降，这样的变动让沙丁鱼无法适应，严重降低了身体的活力，导致其被大量冻僵冲上岸。

Seawater temperature variation from day to day, the afternoon was relatively warm, but the temperature fell sharply in the night, such a change to sardine can not adapt to and seriously reduce the vitality of the body, causing it to be a lot of frozen washed ashore.

在这种剧烈降温的环境下，鱼类变得不活跃，随海浪被冲上海滩。这些沙丁鱼大部分时间生活在亚热带海域，只有每年初夏的时候会洄游到库页岛西南海域育肥，等到10月中旬再回到亚热带海域。
