The sea trout is characterized by a distinctive feature - its elongated, torpedo-shaped body. Its sides shimmer in a gray-silver color, while the back is gray-green in color. The belly, on the other hand, is a brilliant white. Another characteristic feature that it has in common with other trout species is the presence of an adipose fin. This fin is located on the upper part of the back and is often clearly visible. The adipose fin serves as a stabilizer for the sea trout while swimming and contributes to its efficient movement in the waters in which it lives.
