The article highlights the successful commercial-scale breeding, propagation, rearing, and sale of aquarium fish species in the Howrah and South 24 Parganas districts of West Bengal, India. It focuses on the innovative practices of two experienced aquarium fish farmers, Sri Bikash Sau and Sri Swapan Parua, who have introduced a novel approach to aquarium fish culture in open earthen and common village ponds. The success stories of Sri Bikash Sau and Sri Swapan Parua serve as inspirations for small and medium-scale farmers and aqua-entrepreneurs. Their innovative approach to open pond production for aquarium fishes demonstrates the increasing potential and expansion of the aquarium fish business in the region.

The Late Sri Kripan Sarkar was an enterprising ornamental fish breeder-cum-farmer par excellence, exporter and supplier of the same from northern part of West Bengal. As proprietor of Rainbow Ornamental Fish Farm, at Bakshipara Village in Jalpaiguri District, he was an expert and authority in scientific breeding, larval rearing, propagation, research and experimentation on economically important freshwater ornamental fishes. There was a time when Sri Sarkar was the only commercial ornamental fish breeder in north Bengal. This article documents his experiences and career as an influential pioneer in the ornamental fish culture trade.

Eight thematic reviews prepared as preparation for the Global Conference on Aquaculture Millennium +20 (GCA +20) have been published in a Special Issue of the Journal of the World Aquaculture Society "Aquaculture for Food and Sustainable Development". A group of experts prepared advanced working drafts of each thematic review and the key findings from each theme were presented and discussed by expert panels during the GCA +20. Participants were then invited to provide their feedback and perspectives on the reviews and their key messages for consideration in finalisation of the papers. The reviews are available for free download.

CAA7 will be held in Hainan, China, from 29 November to 2 December, with an option for online participation via Zoom for people that cannot attend in person. The theme of the symposium is "Sustainable development of cage aquaculture in Asia". Sessions will be held on: Production systems; breeding and seed production; nutrition and feed; carbon sink and fouling organisms; health and environmental management; economics, gender, livelihood and policy.

The symposium is organised by the Asian Fisheries Society, Hainan University, Shanghai Ocean University, and the China-ASEAN "Belt and Road" Joint Laboratory of Mariculture Technology, Center for Ecological Aquaculture.

The concept of “empowerment” was introduced at the International Women’s conference in 1985 at Nairobi, which defined empowerment as a “redistribution of social power and control of resources in favour of women”. In recent years the development of women has emphasised providing equal opportunities to women by removing gender bias, empowering, and creating self-reliance among them. Empowerment of women and gender equality is recognised globally as a key element to achieve progress in all areas. Globally, the role of women and the need to consider gender issues in aquaculture development was first recognised by the FAO-NORAD sponsored workshop on “Women in Aquaculture” in 1987.

This story looks back over the last century at the fisheries scenario in Moyna, a community development block in West Bengal, India. The tremendous success of aquaculture practice in Moyna has strongly influenced farmers of surrounding districts to convert agricultural lands to aquaculture. Capture fisheries in Moyna have had a rich heritage that has gradually evolved over time. Beginning with traditional deep-water paddy-cum-capture fishery, as practices evolved the fish component of the crop began to take on greater significance, becoming the most profitable part. Over time, farmers have shifted to an aquaculture model, achieving an average yield of 12.5 tonnes/ha/year.

About 200 families that were displaced by construction of the Jurala reservoir have found new employment in fishing and value-added industry. Local people who up fishing add value to their catch by keeping it for live sale in locally-manufactured cages. Local people also use the live fish to prepare a variety of fresh fish dishes, servicing the tourist trade attracted to the reservoir. Over 400 people are now directly or indirectly self-employed through these practices. This article describes the new practices and the improved income that is being generated by fishers and local entrepreneurs.
