Analytical framework for rethinking aquaculture development for smallholder farmers.

A framework for a new type of analytical approach to aquaculture development is presented. It focuses onsmallholder farmers in the context of their environment and managed natural resources, and considers experiences gained in past initiatives; makes extensive use of existing information from previous studies; employs a participatory approach and bases work on partnership among farmers, researchers and extensionists: (both government and/or nongovernment organizations) in field trials.

Using the sustainable livelihoods framework to identify constraints and opportunities to the development of freshwater prawn farming in southwest Bangladesh

A conceptual framework, drawn from an approach to poverty reduction known as the Sustainable Livelihoods Approach (SLA), is applied to understanding the role of freshwater prawn, Macrobrachium rosenbergii, farming in gher (modified rice fields with high, broad peripheral dikes) systems in southwest Bangladesh. Gher farming potentially allows incorporation of a wide variety of crops together with prawn, fish, dike crops and rice culture.

Training resource book on a participatory method for modelling bioresource flows.

This guidebook helps researchers and extensionists learn an easy rapid appraisal technique that enables farmers to draw conceptual models of their farm systems. The drawings help researchers and extensionists to understand quickly local agricultural practices and identify entry points for integrating new enterprises into the farm. The book can be used independently or to accompany two videos, Aquaculture and the Rural African Farmer and Pictorial Modelling: A Farmer-Participatory Method for Modelling Bioresource Flows in Farming Systems.

Report on partner NGO refresher course (3): (for field assistants recruited in 2001)

Freshwater Resources Research Program of the WorldFish Center is aimed at improving food security and eradicating poverty by introducing small-scale fresh water aquaculture as an element into the economic activities of resource poor households in rural area (Bangladesh). The target groups are the poor producers and consumers who can benefit from the better use and management of aquatic resources. Year 2000 was the beginning of the USAID funded Development of Sustainable Aquaculture Project (DSAP).

Production priorities overshadow genetic quality at African fish hatcheries

Based largely on FAO programs that address rural poverty, small-scale hatcheries have been developed in Africa to produce catfish and tilapia fingerlings. Production practices that fail to maintain genetic diversity, however, often limit the growth performance of the fingerlings. Growth rates up to 40% lower than those of wild fish potentially cost African farmers over U.S. $200 million a year.

Proceedings of review workshop on aquaculture technology

Aquaculture is considered to be one of the major components in farming system in Bangladesh because of the potential role it can play to combat protein malnutrition, employment generation, poverty alleviation and foreign exchange earnings. However, proper identification of the problems faced by the farmers as well as selection of appropriate technology and its transfer to the farmers is a must to make the aquaculture practices effective and sustainable.

Pawpaw seed as fertility control agent on male Nile tilapia

To find out if pawpaw (Carica papaya) seeds can induce sterility in male Nile tilapia (Oreochromis niloticus) and to determine if sterility so induced is reversible or otherwise, mature male tilapia of mean weight 40 g were treated for 30 days with a low dose (4.9 g/kg/day) and a high dose (9.8 g/kg/day) of ground pawpaw seeds incorporated into their feed. Fish of similar sizes in the control experiment were fed with feed that did not contain pawpaw seed.

Opportunities and challenges for African aquaculture

Starting from a small base, aquaculture production in Africa registered annual growth rates equal to or above those in other regions. This expansion was due to significant increases in a few African countries. Increasing demand coupled with rapidly dwindling catches from capture fisheries, the implementation of novel participatory approaches to technology development and transfer, and the emergence of a few successful large-scale tilapia culture operations directed at the export market offer opportunities for further expansion in both the small-scale and large-scale commercial sectors.

Networth: research with women fish farmers in Bangladesh

A narration of the collaborative work between ICLARM fish farming / culture program in Bangladesh with the Bangladesh Fisheries Research Institute on potential use of seasonal ponds as small scale fish ponds. The ponds could be used to increase fish production in Bangladesh up to 80%. The women could manage the fish culture and in the process of doing so, contribute to household income, provide employment and improve family nutrition.
