Pangasius, or shark catfish, is a ray-like fish belonging to the Pangasiev family. Representatives of this species live in large rivers and lakes of Southeast Asia (Tonle Sap, Chauphraya, Mekong, etc.). In addition, they are grown in artificially created ponds for industrial purposes.
Pangasius has an elongated flattened body without scales, a flattened head with a blunt snout and a large mouth with two pairs of antennae, vaguely resembling a catfish. The back of the fish is dark gray, the sides and belly are silvery-white, the fins are black. Juveniles have a dark band on the body along the lateral line.
Sok sharks can reach impressive sizes. In the wild, individuals are often 120-130 cm long and weighing 35-45 kg. At the same time, the body weight of fish grown in artificial water bodies rarely exceeds 1.5 kg.
