When policy makers start hearing voices

This article discusses a process for transacting pro-poor policy change is discussed drawing on examples in aquaculture from India. Based on research and development experience in Bihar, West Bengal and Orissa, and some further work in the western and central regions covering tribal populations, the Fisheries Development Commissioner encouraged the NACA-STREAM Initiative to recommend reforms under the FFDA scheme or even suggest a new “tribal” rainfed farming component that could be launched in the next year.

The STREAM Initiative: Promoting participation, communication and policies that support the livelihoods of poor aquatic resource users in the Asia-Pacific

STREAM is a regional initiative that will support capacity building among local government institutions, NGOs, and community groups involved in aquatic resources management. It will support community-based learning initiatives, develop a regional communications and learning strategy and support on-going policy and institutional changes in the region to enable aquatic resources users to participate more effectively in policy-making processes, and encouraging the development of more responsive government institutions.

Reaching the rural poor: Developing a strategy for the promotion and dissemination of participatory aquaculture research - a case study from eastern India

This paper reports on the development of a communication dissemination strategy for aquaculture recommendations resulting from participatory research in eastern India. It focuses on the rural poor who have limited access to resources and no effective aquaculture extension support. Important matters in relation to access to extension messages include socio-economic issues, access to TV and radio receivers, literacy levels and language. The paper shows the relative accessibility of different types of extension media for the different stakeholders.

Brief note on the state of the art of Macrobrachium culture in Thailand

The farming of the giant freshwater prawn has expanded rapidly in Thailand. Production has increased from less than 3 tons/year in 1976 to an estimated output of more than 1,200 tons in 1982. This rapid growth was largely stimulated by the Chachoengsao Fisheries Station established solely to promote culture of the prawn. Services of the station comprise the production and free distribution of post-larvae from 1976-1978, along with training and extension programmes.
