Inhabits marine waters, estuaries and large lakes (Ref. 59043). A midwater species, rarely far from shore, primarily anadromous in the west and lacustrine in the east; shoaling at least during spawning season (Ref. 4545). The essential part of its life is spend in the estuarine zone, with just short incursions in the littoral zone (Ref. 51442). The migratory form is grouping together in the estuarine zone for reproduction (Ref. 51442). Enters the rivers for spawning on sandy or gravely bottoms (Ref. 13696). Spawns in tributaries of lakes or along shallow shores of lakes and rivers on sand, gravel, stones and plant material, preferably in fast-flowing water (Ref. 59043). Reproduction takes place between February and May, depending on the water-temperature (Ref. 51442). Produces 8,000-50,000 yellow eggs with a diameter of 0.6-0.9 mm which adhere to the bottom (Ref. 13696, Ref. 51442). Eggs hatch in 3-5 weeks and the larvae descend to the estuarine zone (Ref. 13696, Ref. 51442). Feeds on shrimps and small crustaceans; larger individuals feed on small fish (Ref. 30578, Ref. 51442). Utilized as foodfish, smoked, as bait and fish oil (Ref. 35388). Smells like cucumber (Ref. 37032, 51442). Locally threatened due to pollution and barriers to migration (Ref. 59043).
一個中層水域種,很少地遠離海岸, 主要溯河洄游產卵在東部中的西方與湖泊者中; 在產卵季節的時候群集的至少。 (參考文獻 4545) 他的生活的必要部份是在河口的區域中度過, 在海濱的區域中的僅僅短的侵入.(參考文獻 51442) 迴游的形式對於繁殖在河口的區域中一起是配列。 (參考文獻 51442) 它進入河進行產卵沙的之上或者嚴重地底部.(參考文獻 13696) 繁殖在二月之間發生與五月, 依據水溫而定.(參考文獻 51442) 它生產 8,000-50,000 黃色卵有黏附在底部的 0.6-0.9 mm 的直徑.(參考文獻 13696, 參考文獻 51442) 他們在 3-5個星期中孵化,而且仔魚下降到河口的區域。 (參考文獻 13696, 參考文獻 51442) 吃蝦與小型甲殼動物; 較大的個體吃小魚。 (參考文獻 30578, 參考文獻 51442) 他們在 3-4 年 (15-18 公分) 中在半鹹淡的族群性成熟了, 在淡水中的 1-2 年 (810 公分的)。 用來作食用魚,煙燻了, 如誘餌與魚油。 (參考文獻 35388) 聞相似的黃瓜。 (參考文獻 37032, 參考文獻 51442)
