Description

The Norway bullhead is a small fish that only grows to 7.4 cm in length. It has a row of bony knobs above the rough lateral line.

It feeds on small crustaceans (amphipods, decapods) and fishes. It spawns in early spring, laying demersal eggs, in clumps on bottom, diameter 2 mm. Larvae are pelagic. A population of Norway bullhead is capable of doubling its numbers in under fifteen months.

Habitat

It is found on hard sea bottoms (gravel or shells) or among seaweeds, in cold areas – even with temperatures below 0 °C. It feeds on small fish, amphipods and other crustaceans.
