“The middle reaches of the Ganga, from Haridwar to Patna, constitute the most dynamic zone for carp recruitment. Here, depth varies from 3 to 12 metres, current velocity between 0.3 and 0.8 m/s, and turbidity ranges from 30 to 120 mg/l. Spawning of Catla catla coincides with the southwest monsoon’s first floods (June–July), when water temperature drops slightly to 26–28°C. The eggs are semi-buoyant, requiring a minimum current of 0.5 m/s to remain suspended until hatching.
