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).
成魚在 0.5 到 3 公尺的深度範圍完全地產卵於湖中, 在細砂礫之上。 二個產卵的品系被知道: 一直到十二月底在來自十一月的起點的湖的西北角中產卵; 另一個在東南方的角落產卵, 從直到三月底的一月中或一月底。 這一個魚一年兩次接近海岸: 從四月直到七月與從十月直到十二月。 在冬季中期而在夏天底,它離開岸邊到停留在較大的深度。 成魚只吃沙蟲 (片腳類動物) 。 (參考文獻 593)
