| Thông tin chủ yếu | Stein, D.L., 1986 |

| Các chú thích | Demersal (Ref. 94970). Inhabits stony bottoms (Ref. 4701). Benthic. Feeds on amphipods, crustaceans, oikopleura and fishes (Ref. 4701, 58426). It is preyed upon by Atlantic cod and thick-billed murres (Ref. 5951). Common in the waters around Svalbard, but very little detailed knowledge exists regarding its life history, feeding and reproductive biology. A demersal and slow moving fish (Wiener-roither et al. 2011; pers. obs.), feeds on pelagic and hyperbenthic invertebrates such as krill and amphipods, but also polychaetes and larval stages of fish (Hutchings 2002; Roshchin 2006). Spawning has been reported to occur in August-September (Andriashev 1954; Wienerroither et al. 2011), although other reports indicate that it may be extended to January/February (Hutchings 2002). Furthermore, eggs have been observed attached to rocks (Wienerroither et al. 2011) (Ref.94970 ) |
