Remembering distinguished scientists as contributors to growth and development in Indian fisheries and aquaculture sectors

Remembering distinguished scientists as contributors to growth and development in Indian fisheries and aquaculture sectors

Over the past century, a generation of Indian scientists, educators and administrators laid the foundations of the country's modern fisheries and aquaculture sectors. This tribute remembers 65 of them, all of whom have since passed away. Their work covered inland and marine fisheries, freshwater and brackishwater aquaculture, fish breeding and hatchery technology, fish health, genetics, nutrition, post-harvest technology and fisheries education. Many led national research institutes, universities and state fisheries departments, while others served with international organisations such as FAO. Their research and leadership helped increase fish production in India and expanded knowledge of fish biology and aquatic ecology. The article brings together, in a single table, the dates of birth and death of each person, along with their main fields of work and the institutions they served. It is offered as a source of inspiration for students and young researchers in fisheries science.

The humane side of data: When numbers don't speak for themselves

The humane side of data: When numbers don't speak for themselves

Small-scale fishing communities in Gujarat depend heavily on marine resources, yet many live with uncertain incomes, declining catches and months without earnings during the annual fishing ban. A socio-economic survey of fishing villages around Veraval Harbour found that many artisanal fishers miss out on available assistance because they do not know it exists or how to apply. Awareness of assistance schemes is low, and paperwork, online application systems and language barriers make access harder for families with limited education. Where cooperatives are active, communities are better organised and better informed.

Closing the awareness gap through local-language outreach and closer contact with extension services would help support reach those it is meant for. The survey also shows the responsibilities of field researchers: explaining their role and limits from the start, using the local language and sharing practical information on available support, so that research does not raise expectations it cannot meet.

Successful spawning and rearing of silver biddy, Gerres oyena in Abu Al Abyad Island, Abu Dhabi, United Arab Emirates

Silver biddy, Gerres oyena.

Silver biddy (Gerres oyena), known locally as badah, supports commercial fisheries across the Indo-West Pacific, but wild stocks in the Arabian Gulf are declining. Staff at the Aquaculture and Marine Studies Center on Abu Al Abyad Island, Abu Dhabi, have now spawned and reared the species in captivity. The team conditioned wild-caught brood stock on a supplemented diet, then induced spawning with hormone injections in April 2025. Over six weeks, the fish produced 2.9 million fertilised eggs, with a hatching rate of 76.9%. Larvae were raised on green water, rotifers, Artemia and artificial feed, producing 423,000 fry at a survival rate of about 19%. In the nursery, juveniles reached 1.8 g after 100 days with 80% survival.

This article describes each step, from brood stock care to nursery management, and outlines the further research needed to support hatchery production and stock enhancement of this species in the region.

Aquaculture potential of Ophichthys cuchia in Northeast India: Current understanding and prospects

Aquaculture potential of Ophichthys cuchia in Northeast India: Current understanding and prospects

The Gangetic swamp eel, Ophichtys cuchia, is one of the highest-value indigenous freshwater fish in Northeast India, yet almost all of it still comes from the wild. A 2025 market survey in Manipur recorded it selling at Rs. 800/kg against Rs. 150 to 200/kg for common carp. Wild stocks are falling as wetlands are drained, paddy fields are sprayed with pesticides and capture continues unregulated. This review brings together what is known about the biology, nutrition and culture potential of the species, with particular reference to the eight northeastern states. It covers the eel's air-breathing adaptations and tolerance of low oxygen, its protandrous sex change and the breeding problems this creates, nutritional composition, and pond and rice-field trials from Bangladesh reporting yields up to 2,506 kg/ha. Seed supply remains the main obstacle, as no hatchery network produces fingerlings in India.
