Population dynamics of Etelis carbunculus (Lutjanidae in Tonga, South Pacific)

This paper presents a tentative estimate of the parameters L8 and K of the von Bertalanffy growth function, and an estimate of total mortality derived from the analysis, using the ELEFAN I and II programs, of length-frequency data on the snapper Etelis carbunculus (Lutjanidae) collected on seamounts of the Kingdom of Tonga, South Pacific.

Participatory action research on climate risk management, Bangladesh

The rural populations of southern Bangladesh are some of the most vulnerable communities in the world to the future impacts of climate change. They are particularly at risk from floods, waterlogged soils, and increasing salinity of both land and water. The objective of this project was to analyze the vulnerability of people in four villages that are experiencing different levels of soil salinity.

The forgotten service: food as an ecosystem service from estuarine and coastal zones

In this chapter, we review in detail the existing body of literature and knowledge related to the provision of food in estuaries and coastal zones. Both aquatic and terrestrial commodities are considered. The chapter highlights not only the importance of the terrestrial zone in overall food provision but also the substantial contribution of aquatic coastal resources. The various problems that the coastal zone faces in sustaining this important provisioning service in the face of increasing pressure and demands from other sectors are highlighted.

Ex-ante assessment of integrated aquaculture-agriculture adoption and impact in Southern Malawi

There are increasing requirements for impact assessment by development partners in order to increase the accountability and effectiveness of research and development projects. Impact assessment research has been dominated by conventional economic methods. This context challenges agricultural research organizations to develop and apply alternative impact assessment methods incorporating economic, social, and environmental impact components.

Design and implementation of fishery modules in integrated household surveys in developing countries

Fish and other aquatic animals contribute to the food security of citizens of developing countries, both as a source of income and as a component of healthy diets, yet fishing is not currently captured in most integrated household surveys. This sourcebook provides essential technical guidance on the design of statistical modules and questionnaires aimed at collecting fishery data at the household level.

Communication strategy

The CGIAR Research Program on Aquatic Agricultural Systems (AAS) is one of the CGIAR’s 15 research programs. Through a program of participatory action research, referred to as “Research in Development”, the Program aims to improve the lives of the many millions of people who depend on aquatic agricultural systems. This Strategy will create the platform to capture, collect, produce, manage, brand and share information that is generated throughout the Program’s lifecycle.

CGIAR Research Program on Aquatic Agricultural Systems Roll-Out Handbook. Ver. 1.0. May, 2012

This handbook is a guide to procedures and practices that should be observed during hub roll-out by the teams coordinating the planning, implementation and reporting of the activities of the CGIAR Research Program on Aquatic Agricultural Systems (AAS-CRP). Given that the program promises to change the way research in development is planned, implemented and reported, it is important that similar practices be observed from the start. This will assist later cross-hub comparisons.

Cage-pond integration of African catfish (Clarias gariepinus) and Nile tilapia (Oreochromis niloticus) with carps

Cage-pond integration system is a new model for enhancing productivity of pond aquaculture system. A field trial was conducted using African catfish (Clarias gariepinus) and Nile tilapia (Oreochromis niloticus) in cages and carps in earthen ponds. This study aimed to assess the production and profitability of different cage-pond integration models of Nile tilapia and African catfish with carps under farmers’ conditions and to recommend the best ones for adoption in Nepal.

Building resilient community fisheries in Cambodia

By bringing together diverse stakeholders in a collaborative process, a WorldFish initiative has strengthened the collective capacity of an emerging grassroots network of fishing communities to: identify and articulate threats; negotiate with authorities to represent the common interests of fishing communities; and collaborate with the Government and private actors to resolve resource conflicts in Cambodia’s Tonle Sap Lake.
