Macrobrachiurn rosenbergii is one of the widely cultured freshwater prawn species globally. India was the third largest producer of this species in 2007 and its aquaculture production rose to 43,000 metric tons (t) in 2005 froin less than 500 t in 1995. However, since then production has been declining and in 2008-09 it was 12,856 t, a reduction of more than 70% compared to 2005. There are several contributing factors to this decline, such as slow growth rate, poor survival, disease outbreaks, increase in cost of production, and availability of low risk alternative fish species.
In July 2011, the CGIAR approved the CGIAR Research Program on Aquatic Agricultural Systems (AAS) in recognition of the importance of these systems and the potential they provide for reducing poverty. Our goal is to reduce poverty and improve food security for people whose livelihoods depend on aquatic agricultural systems.
Fisheries and fish supply are undergoing a fundamental structural transition, as indicated by a ten country analysis. Aquaculture now provides around half the fish for direct human consumption and is set to grow further, but capture fisheries continue to make essential contributions to food and nutrition security throughout the global South. Capture fisheries provide diverse, nutritionally valuable fish and fish products which are often culturally preferred and easily accessed by the poor.
Fisheries and aquaculture policy for education, research and extension is derivatives of the main national agriculture policy. Fisheries and aquaculture is a dynamic sub-sector of agriculture sector having high growth potential but with low organizational stature in Nepal. The modern aquaculture along with fisheries practices contributes nearly 1% of Gross Domestic Production (GDP) and 2.68% of Agriculture Gross Domestic Production (AGDP).
More than 2 billion people worldwide, particularly in developing countries, are estimated to be deficient in micronutrients, including vitamin A, iron and zinc. These vitamin and mineral deficiencies are a form of undernutrition affecting children and pregnant women. This fact sheet outlines the key benefits of eating fish, a source of micronutrients and essential acids, in alleviating nutrient deficiency.
Sociological aspects in western Sudan relating to the development of fish farming are discussed as a means of supplementing the local diets.
The Feed the Future Aquaculture project is a five year transformative investment in aquaculture focused on 20 southern districts in Barisal, Khulna and Dhaka divisions, Bangladesh. This report describes the achievements of FtF-Aquaculture project activities implemented during FY12. Some of the targets for production and associated income have not been achieved yet as a large share of the fish will be harvested after closing of the reporting period. However, on the basis of growth monitoring, indications are that production is on track to achieve the targets.
Africa harbours a rich biological diversity of native fish resources. Recognition of the potential to use these resources to make significant contributions towards improving African food security through aquaculture has existed for some time. A key challenge, however, is achieving compatibility between the two urgent, but sometimes conflicting, goals of reducing poverty and food insecurity in Africa through aquaculture development while paying due attention to the conservation of natural biodiversity and fish genetic resources (FiGR).
This document presents ex-ante impact evaluations of research for development projects related to aquaculture in Bangladesh, Malawi and Ghana. The Ghana chapter also includes an ex-ante evaluation of a fisheries project. The case studies utilized preliminary versions of guidelines developed specifically for ex-ante evaluations of aquaculture and fisheries projects. The guidelines, found in A Practical Guide for Ex-Ante Impact Evaluations in Fisheries and Aquaculture, are designed to provide an approach for a qualitative examination of the potential for a project to deliver impacts.
This report describes a study done in 2010 by researchers of the WorldFish Center on water use in Egyptian farms that apply aquaculture – agriculture integration. Two of the four farms that were monitored derived the main income from farming and selling fish, the two other farms were mainly agricultural farms that used reservoirs that were built to store irrigation water for growing fish. The volume of water in which fish were raised from fingerling to market size and that was subsequently used to irrigate agriculture crops was estimated.
