The adults spawn in the lake proper at a depth range of 0.5 to 3 m, over fine gravel. Two spawning stocks are known: one spawns in the northwestern corner of the lake from the beginning of November till the end of December; the other spawns at the southeastern corner, from the middle or the end of January till the end of March. This fish approaches the coast twice a year: from April till July and from October till December. In mid winter and at the end of summer, it leaves the coasts to stay at greater depth. Adults feed exclusively on sand hoppers (Amphipoda) (Ref. 593).
成鱼在 0.5 到 3 公尺的深度范围完全地产卵于湖中, 在细砂砾之上。 二个产卵的品系被知道: 一直到十二月底在来自十一月的起点的湖的西北角中产卵; 另一个在东南方的角落产卵, 从直到三月底的一月中或一月底。 这一个鱼一年两次接近海岸: 从四月直到七月与从十月直到十二月。 在冬季中期而在夏天底,它离开岸边到停留在较大的深度。 成鱼只吃沙虫 (片脚类动物) 。 (参考文献 593)
