Labeo rohita diagram


Rohu or Labeo rohita is a freshwater fish mostly found in rivers and ponds. They are geographically distributed along temperate and tropical regions like Vietnam, Pakistan, Nepal, India, Myanmar and Bangladesh. Labeo breeds mostly in bund types of tanks and rivers but not in confined waters.


  • The adult Labeo fish is about 0.5 to 2 metres in length and weigh around 4 kg (maximum up to 45 kg).
  • Their body is brownish or bluish on the dorsal surface and silvery-white below. Also, the body surface is covered with large and overlapping cycloid scales that are of taxonomic importance. These cycloid scales are round, bony and flat. The scales overlying the lateral line are perforated by the tubes of the lateral line system.
  • They have a compressed and fusiform body that can be distinguished into the head, trunk and tail.
  • They have a depressed head which forms an obtuse, short, and blunt snout. It also has paired eyes and paired nostrils. The head bears a fringe-lipped mouth in the subterminal region. The mouth is bounded by fleshy lower and upper lips. Two slender and filamentous barbels arise from the upper lip.
  • Rohu contains homocercal caudal, dorsal, anal, ventral fins and paired pectoral fins. Their fin rays are typically soft. Furthermore, their caudal fins fork into two equal lobes.
  • They have four pairs of gill slits that are covered by the operculum. The large operculum encloses gills as well as the branchial chamber.
  • Weberian apparatus is present between the inner ear and swim bladder. They have mesonephric kidneys.
