Turbot belongs to a small family of left-eyed flatfish (both eyes on the left of the body), known collectively as the Scophthalmidae. This family of fish is confined to the north Atlantic basin and includes megrim and brill. Turbot becomes sexually mature at an age of 3-5 years and in most parts of its range spawns in April to August, females each producing up to 10-15 million eggs. Turbot is one of the fastest growing flatfish, with females growing faster than males, in the North Sea reaching a length of around 30 cm (males) and 35 cm (females) in about 3 years. In the Baltic Sea growth is slower, and the males become sexually mature at a length of 15 cm, the females at 20 cm. By 10 years of age growth rates have reduced to 1-2 cm per year for females and less than 1 cm per year for males. Consequently, females are larger than males at any given age. Turbot can attain a length of 1m and a weight of 25 kg. Maximum reported age 25 years. For some reason males are generally more abundant than females. Turbot is distributed from Iceland, down the coast of western Europe and into the Mediterranean. Turbot are typically found at a depth range of 10 to 70 m, on sandy, rocky or mixed bottoms. It is one of the few marine fish species that inhabits brackish waters. Turbot appears to be a rather sedentary species, although some adult migration may occur.
