Trade in fisheries products is an important source of livelihoods for economically underprivileged people in Chhattisgarh. A socio-economic profile of traders and other actors from a domestic fish market is presented, including age, gender, education and income levels. The market infrastructure, distribution channels and species traded are described. Constraints to marketing arrangements are identified and include a lack of cold chain, storage and transport facilities.

The fourth major international event on giant freshwater prawns was organised by the Asian Institute of Technology from 20-24 March 2007. The conference, organised by Salin Krishna and Michael New, built on a series of highly successful events that trace back to the very beginnings of the industry. The first conference, Giant Prawn 1980 brought together all those involved in freshwater prawn research and farming for the first time and set many priorities for future research and development.

Community fishing is a unique feature in the state of Assam, India. The present case study narrates a community fishing event in the floodplain wetlands (beels) of Kamrup District in Assam, India, witnessing participation of different tribal communities in fishing and the modus operandi of diverse types of fishing gears with catch details. The design details of the gear were documented. The communal fishing practices of local communities are described along with the respective roles of men and women.

In Nepal, low quality and seasonal access to fish seed is an important restriction on the development of the aquaculture sector. Commercialisation of fish farming cannot progress rapidly in the absence of critical inputs and a regular supply of quality fish seed is an integral requirement for the transition of fish farming from a subsistence activity to a commercial enterprise. Participatory market chain approaches are a key tool for the social and economic improvement of farmers and market participants.
