N°1 | The Brill fish

The brill fish belongs to the Scophthalmidae family. The minimum size of capture is 30 cm but can reach 75 cm for 6 kg. He can live up to 3 years. It breeds from late spring to early summer. The female can lay up to 15 million eggs. It can be fished all year. The brill has an oval body. It rests on its right side and has its left side. Thus, when placed with the head facing left, both eyes are located above the mouth. Its common name of brill comes from a particularity of its dorsal fin, whose origin is far in front of the eye and whose first rays are free and branched. The distance between the two eyes is greater than the diameter of one eye. The lateral line is very curved at the pectoral fin. As with many flatfish, the coloring is variable and depends on the biotope. The brill is indeed capable of homochromia, i.e. to match the color of the background. The coloring is rather brown, more or less speckled, and also varies according to the environment on a live fish. It has many round spots whose edges are incomplete rings of darker colors. The blind side is whitish.
