BIOLOGY
Brill belongs to a small family of left-eyed flatfish (they lie on their right side and both eyes are on the left). They can attain a length of 75cm, but usually no more than 55cm, and a weight of around 2.5kgs for females (who are the larger). Females are fully mature at about 4 years and 40cms. Maximum reported age is 6 years. They spawn in spring and summer.
ADVICE
Brill is mainly taken as by-catch in beam trawl fisheries in the North Sea. A considerable proportion of the catch is immature and the stock over-exploited. Avoid eating beam-trawled brill from the North Sea. The state of the stock in the Baltic Sea is unknown. Avoid eating immature fish (less than 40cm) trawled from all areas as these will not have had chance to spawn.
