Food and feeding habits
Feeds on small crustaceans and juvenile fish.
They grow very slowly and do not reach sexual maturity until 10-15 years of age when they reach a length of 15-20 cm. Live-bearing fish with internal fertilisation. After mating, sperm are retained inside the female for several months until the eggs are fertilised. The eggs hatch inside the female and the larvae emerge in summer. Fecundity is 10,000 to 30,000 larvae, depending on the size of the female. Larvae are 3-4 mm long when hatched.
They are of limited commercial importance. They are caught as by-catch in other demersal fisheries.
