Fish pituitary gland collection and supply as a vocation in West Bengal, India
In retail fish markets in Kolkata city proper, suburbs and neighbouring districts, pituitary glands are collected as a profession from the heads of mature fish. The preserved glands are used to induce breeding via hypophysation in carp hatcheries throughout West Bengal, playing an important role in the availability of carp seed to support aquaculture operations. This article describes the livelihoods of pituitary gland collectors and traders in West Bengal, India.
Scenario of captive production of Clarias magur in India
Clarias magur, locally known as magur, is a well-preferred medium sized catfish among Indian consumers. Difficulties such as shortages of effective inducing agents and the erratic response to induced breeding, low survival in different life stages, slow growth, and lack of effective feeds have been a bottleneck for the wider adoption of this fish by farmers. There has been considerable research to simplify the technology and disseminate it among farmers over the last decade. This article summarises these attempts and describes the present level of its technology practiced in India.
Exotic trout fisheries resources and potentialities in Uttarakhand
Commercial trout farming in Uttarakhand has advanced progressively during the last decade and has become a profitable occupation among the rural masses especially in the colder regimes where no other fish farming has possibilities. The rainbow trout here plays the most dominant role as a commercially important candidate species for culture in this hill locked Himalayan state of India. This article describes the current status of trout fisheries resources and trout aquaculture in Uttarakhand, and their potential further development.

Induced breeding of farm-bred and pond-raised critically endangered peninsular carp, Hypselobarbus pulchellus
Hypselobarbus pulchellus is endemic to the peninsular rivers of India, mainly the Krishna, Godavari, Tungabhadra, Sita and Tunga. It once formed a major fishery of the Tungabhadra reservoir but has declined to the status of a critically endangered species. H. pulchellus is a bentho-pelagic species which inhabits the deeper part of large streams and rivers along the base of ghats. It is the only indigenous fish that consumes aquatic weeds and submerged grasses, and could play a role in controlling aquatic vegetation in reservoirs, tanks and irrigation canals. Capable of attaining 8 kg, H. pulchellus would make a welcome addition to pond culture practices of India, especially for composite fish culture. This article gives an overview of the breeding and seed production technologies developed by ICAR-CIFA for farm-bred and pond-raised H. pulchelllus.
Moyna model of major carp farming in Purba Medinipur District, West Bengal, India
The ‘Moyna Model’ is accepted as an example for freshwater fish culture throughout West Bengal. Moyna is a great example of the freshwater fish culture revolution in West Bengal and a new horizon for culture of the major carps. Moyna fish farmers have adapted the procedures of Andhra farmers incorporating their own blend of experience, skill and technology. This article describes the history and development of major carp culture practices in Moyna, challenges faced by the industry including groundwater exploitation, and documents the experience of some progressive farmers.
