Brill, scientific description Scophthalmus Rhombus is fish whose meat is very valuable and has a delicious taste. Brills can be found along the shores of the Adriatic Sea. They can be fished throughout the year, although they are more abundant in winter. Trawls and longlines are typically used. Despite being a sea fish, when young you can also find it in some brackish lagoons, since it can tolerate very well the changes in water salinity.
