生態學
海洋; 淡水; 半鹹淡水; 溯河洄游 (Ref. 51243), usually ? - 50 m (Ref. 4545). 溫帶; 70°N - 43°N, 9°W - 55°E
North Atlantic: White Sea southward to western coasts of France including Baltic Sea, southern North Sea and British Isles (Ref. 4545); the Gironde estuary is the southern limit of his distribution (Ref. 51442). Landlocked populations in lakes of coastal areas of North, Baltic, White and Barents Sea. North to about 68° N in Scandinavia (Ref. 59043). The former nominal subspecies Osmerus eperlanus eperlanus is recorded from the coasts and drainage of White and Barents Seas westward through Baltic Sea to Denmark and it is primarily lacustrine (Ref. 4545). The former subspecies Osmerus eperlanus schonfoldi (Rutty 1772) is sympatric with the nominate subspecies in parts of Poland, Denmark and the Baltic, and it is primarily anadromous (Ref. 4545).

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).

Spawns in lower reaches of streams, deeper parts of lake in sand bottoms (Ref. 682). Spawning takes place with the melting of snow (Ref. 682). Many individuals die after the spawning (Ref. 682). Migratory form generally with rapid growth, more eggs, live longer; individuals feeding on fish grow bigger (Ref. 682). ). Becomes sexually mature in 3-4 years (15-18 cm) in brackish populations, 1-2 years (8-10 cm) in freshwater.北大西洋: 白海向南至法國包括波羅的海，北海南部與英國島的西海岸;(參考文獻 4545) 法國革命時期的穩健共和黨河口是他的分布的南方限制。 (參考文獻 51442) 對丹麥，先前的名義上的亞種 Osmerus eperlanus eperlanus 距離海岸被記錄與經過波羅的海向西白色的流域與巴倫支海，而且它主要湖泊。 (參考文獻 4545) 前亞種 Osmerus eperlanus schonfoldi(遍地轍痕的 1772) 重疊分佈那在波蘭的部份, 丹麥與波羅的海中提名的亞種, 與它主要溯河洄游產卵.(參考文獻 4545)
