越冬洄游

耳石中Sr、Ca浓度比例在第5至第7测点出现第1个高峰，这与稚鱼为了越冬洄游到海中时间相吻合。

The first peak of Sr / Ca concentration ratio appeared at the 5 th ~ 7 th measurement point that coincided with the time of migration of the juvenile fish to the sea for overwintering .

物理环境适合度与鳀鱼的分布有着良好的匹配，适合度由低到高的负梯度方向决定了鳀鱼的越冬洄游路线，适合度高值区恰是越冬鳀鱼的密集区；

The physical environmental fitness matches very well with the distribution of anchovy . The negative gradient direction of the fitness determines the route of the wintering migration of anchovy , as the areas with highest fitness just coincide with the areas with highest density of wintering anchovy .
