The freshwater catfish Heteropneustes fossilis is a high-priced fish, well regarded in India for its nutritional and medicinal properties. The first successful induced breeding of this fish was in 1956 at Bangalore Central College (under the then Mysore University), although seed production was not standardised until 2000, at ICAR-CIFA, Bhubaneswar. This article describes broodstock maintenance, induced breeding techniques and the nursing of H. fossilis larvae in small ponds for sale in fish seed markets.

Annual flooding of the Brahmaputra and Barak rivers provides Assam with some of the finest floodplain wetlands in India. Local people have adapted their livelihoods to the flood cycle and fishing remains a traditional activity of tremendous importance in rural communities, with a diverse range of fishing gear and methods developed. This article documents some of the major fishing gears of Assam, with reference to their efficacy and targeted fish species.

Women's engagement in fisheries can be viewed from social, political and technical perspectives, all of which show that the role of women is often underestimated. In the fisheries sector participation by women may only become visible after the landing of the catch. The inadequate recognition of women's contributions hampers development, slowing progress in reduction of poverty and food insecurity. This article examines the diversity of women's involvement in fisheries and aquaculture and highlights opportunities to increase the participation of women.

Marine aquaculture of high value species such as fish is generally reliant on external food supplies and has a negative impact on water quality, generating high organic and nutrient loadings. Integrated multi-trophic aquaculture offers a solution to reduce environmental impact of farming systems, culturing complimentary species that can recycle nutrients and reduce nutrient pollution while generating additional products for sale. This article looks at species selection and integration of trophic levels in system design.
