Aquaculture Asia Magazine

Aquaculture Asia Magazine is an autonomous publication that gives farmers and scientists in developing countries a voice. Stories concern the small-scale aquaculture prevalent in the region and the circumstances of farmers trying to make ends meet in an increasingly globalised world. We accept articles on any aspect of aquaculture and the related processing, marketing, economic, environmental and social issues. An RSS feed is available if you wish to stay informed of new issues.

Concept of seed production of Heteropneustes fossilis in farmers' fields in West Bengal, India

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.

Fishing gear and practices in flood waters of Assam

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.

Fisherwomen empowerment: Shedding light on the invisible gender

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.

Integrated multi-trophic aquaculture systems: a solution for sustainability

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.
