生物学特性     字汇 (例如 epibenthic)

Inhabits inshore waters, deeper waters in winter in Skaggerak, preferring sandy bottoms, rarely with stones. Maximum depth reported at 270 m (Ref. 28197). Temp. range: 4.0-8.0 °C. Feeds on bottom crustaceans and polychaetes. Matures after about 1 year; a few spawning in the second year (Ref. 722). The eggs are laid in seaweed (Ref. 9900). Spawns in February - April, female laying 2,500-3,000 yellow eggs with a diameter of 2 mm. Period of development is very long and 6-8 mm long pelagic larvae hatch after 10-11 months (Ref. 35388).

栖息于近岸水域,较深的水域冬天时在 Skaggerak, 偏爱砂质底部, 很少有石头。 温度范围: 4.0-8.0 ° C. 吃底部甲壳动物与多毛类动物。 在大约 1 年之后成熟; 一些在第二年产卵.(参考文献 722) 卵在海草中生产。 (参考文献 9900) 产卵在二月 -四月, 母鱼产下 2,500-3,000 黄色卵有 2 mm 的直径。 发育期非常长,而且 6-8个 mm 长大洋性仔鱼在 10-11 数个月之后孵化。 (参考文献 35388)
