Species

Sprat are schooling fish that live in pelagic waters, and are seldom found deeper than 150 m. They often make vertical migrations relative to fluctuating light of day, and go to the surface when the brightness decreases. In the summer they occur higher in the water column, often near the surface.

Haneskjell er et sub-arktisk kamskjell som vokser forholdsvis langsomt. Det kan bli opptil 12−13 cm. På feltene i Nord-Norge når skjellet fangstbar størrelse (65 mm skallhøyde) i løpet av seks til åtte år. I motsetning til mange andre kamskjellarter er haneskjellet særkjønnet og gyter tidlig på sommeren.

Spiny Dogfish has a worldwide distribution and is known to be one of the most abundant sharks. This species is subdivided into several populations, and the Northeast Atlantic stock extends from the Bay of Biscay to the Barents Sea. Tagging studies during the late 1950s showed seasonal movements of this stock from summers off the coast of Scotland to winters in Norwegian waters.
