Length at first maturity / Size / Peso / Age
Maturity: Lm 31.5, range 20 - 30 cm
Max length : 65.0 cm TL maschio/sesso non determinato; (Ref. 9988); peso massimo pubblicato: 3.0 kg (Ref. 6112); Età massima riportata: 23 anni (Ref. 6112)
Small head and mouth. Body is oval. Skin is marbled and smooth. Lateral line almost straight, slight curve above the pectoral fin (Ref. 35388).
Lives most often on stony bottoms. Feeds on a variety of small invertebrates, but polychaetes seem to dominate. Apparently they do not feed in wintertime (Ref. 9900). Marketed fresh and frozen; eaten steamed, fried, broiled, microwaved and baked (Ref. 9988).
Spawning is mainly confined to depths of 55-91 m in the northwestern North Sea and commences at a minimum temperature of 6.5 °C in Scottish waters. Sex ratio is about 1:1, but females progressively predominate upon sexual maturity.
