This comprehensive guide breaks down the core sections of Jhingran’s masterwork, its relevance to Indian fisheries biology, and its role in shaping the "Blue Revolution" of the subcontinent. Key Book Overview Fish and Fisheries of India

V. G. Jhingran’s Fish and Fisheries of India is widely regarded as the First published in 1975 (revised in 1991), it remains the most comprehensive single-volume text on the subject. While some data on production statistics are dated (pre-1990s), the fundamental biological, ecological, and cultural practices described are timeless and essential for any fisheries student.

“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. Any obstruction to flow—natural or artificial—within this 800 km stretch directly reduces annual recruitment by an estimated 40–60%.”

Indian fisheries have several species of Tor (Mahseer) and minor carps that are visually confusing. Jhingran’s page 151 often provides the first definitive break in the identification key, helping researchers distinguish, say, Labeo calbasu from Labeo fimbriatus .
