Ecology of Eumicrotremus spinosus
Main Ref. Stein, D.L., 1986
Remarks 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 )
