Brill, like turbot, belongs to the family Scophthalmidae, a group of left-eyed flatfish (they lie on their right side and both eyes are on the left). Similarly, brill are distributed from southern Iceland, down the coast of western Europe, including the Baltic, and into the Mediterranean and Black Seas. Brill is a shallow-water fish (between 5 - 70m) mainly found in areas close inshore and even in estuaries. Mature fish tend to inhabit offshore areas and are rarely observed inshore. Brill prefer sandy bottoms, but are also found on gravel and muddy grounds. They can attain a length of 75cm, but usually no more than 55cm, and a weight of around 2.5kg for females (which are larger). Length at first maturity is 33-40cm, with females fully mature at about 4 years and 40cm. Maximum reported age is 6 years. They spawn in spring and summer. Larger brill (> 40cm) are primarily piscivorous. Small brill feed on small benthic fishes, sandeels, gobies, anchovy, and crabs; with increasing length the diet moves to small gadoids. Brill grows relatively fast and generally reaches a certain length faster (at younger ages) than flatfish, such as sole and plaice, in the same areas.
