Every spring, as the temperature rises gradually, the ice and snow gradually melt, the rain increases, and the amount of rivers entering the lake begins to increase. The yellow croaker, which is about to lay eggs in the lake, began to gather at the inlets of major rivers around the lake, and then went upstream in droves to their spawning sites handed down from generation to generation.
Therefore, the yellow croaker in Qinghai Lake begins to migrate every year from May, and it migrates all summer and ends in August. Therefore, May-August is the migration season of yellow croaker in Qinghai Lake, and June-July is the peak.
