Rohu fish, which is a freshwater fish commonly found in South Asia, is primarily a bony fish. It has a skeletal structure made up of bones rather than cartilage, which is typical for most fish species. The bones in Rohu provide structure and support, making it a popular choice for culinary use in various dishes.
The rohu fish typically has one dorsal fin, one caudal fin, two pelvic fins, and two pectoral fins, totaling six fins.
Rohu fish produce upto 1 lakh eggs/kg body weight. Depending upon the weight of the fish it can produce upto 27 lakhs eggs (~ 20 to 30 % of body weight).
The zoological name for dohra is Labeo rohita, commonly known as the rohu. It is a species of fish belonging to the carp family and is native to the rivers and lakes of the Indian subcontinent. Rohu is an important fish in aquaculture and is highly valued for its taste and nutritional value.
Rohu fish, like all vertebrates, have bilateral symmetry. This means they have symmetry across one plane (known as the sagittal plane, and directly down the centre of their body), which means one side of their body approximately mirrors the other side.
Te Rohu died in 1850.
