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).
陆封的形式偏爱低的温度溪流, 在 15个 ° C. 之下 海洋回游形式的幼鱼在 2 岁进入海洋而且回到当他们是 4 年或更老的时候，河进行产卵。 发现于 13-15个 ° C 的夏天水温了。 (参考文献 12218) 食肉动物, 吃昆虫与浮游生物。 (参考文献 12218) 被烟熏而且冻结的生鲜使用; 能被火烤, 微波而且烧烤。 (参考文献 9988) 两种形式: 陆封的形式达到 35 公分 , 与 70 公分的海洋形式。 (参考文献 9137)
