Labeo Rohita
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).
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.
