生物學特性     字彙 (例如 epibenthic)

The land-locked form prefers low temperature streams, below 15°C. Young of the sea-run form enter the sea at 2 years of age and return to the rivers for spawning when they are 4 years or older. Found in summertime water temperature of 13-15° C (Ref. 12218). Carnivore, feeding on insects and plankton (Ref. 12218). Utilized fresh, smoked and frozen; can be broiled, microwaved and baked (Ref. 9988). Two forms: the land-locked form which reaches 35 cm, and the ocean form of 70 cm (Ref. 9137).

陸封的形式偏愛低的溫度溪流, 在 15個 ° C. 之下 海洋迴游形式的幼魚在 2 歲進入海洋而且回到當他們是 4 年或更老的時候,河進行產卵。 發現於 13-15個 ° C 的夏天水溫了。 (參考文獻 12218) 食肉動物, 吃昆蟲與浮游生物。 (參考文獻 12218) 被煙燻而且凍結的生鮮使用; 能被火烤, 微波而且燒烤。 (參考文獻 9988) 兩種形式: 陸封的形式達到 35 公分 , 與 70 公分的海洋形式。 (參考文獻 9137)
