The WorldFish Center: Malawi

The role of the WorldFish Center is to research and disseminate appropriate aquaculture and fisheries technologies for sustainable agricultural intensification. To achieve these goals the WorldFish Center works in partnership with the government of Malawi. It leverages success by collaborating with both local and overseas academic research organizations, drawing funding from the global development community.

Understanding livelihoods dependent on inland fisheries in Bangladesh and Southeast Asia: Vietnam PRA report

During the period of May to July 2002, An Giang University, in conjunction with the Chau Phu, Thoai Son and Chau Doc District People's Committees, and Can Tho University conducted Participatory Rural Appraisals (PRAs) in four different Provinces. The research findings from this study are presented in this report. The purpose of this exercise was to better understand the livelihoods of people living in rural areas and depending mainly on inland capture fisheries.

Traditional fisheries development in the Philippines.

Development programmes aimed at raising income levels of the half-million Philippine traditional municipal fishermen have emphasized production-oriented projects designed to up-grade vessels and gear. Review of recent biological, technical, and socio-economic research provides evidence that technology-based efforts have generally not been successful, and that the coastal resources fished by municipal fishermen are not as extensive as previously supposed.

Scaling out enhanced floodplain productivity by poor communities: aquaculture and fisheries in Bangladesh and eastern India

Rearing fish in seasonal floodplains raises productivity but can adversely affect the poor and the biodiversity of important natural fisheries. Equitable community institutions enable poor rural households to cooperate with landowners and adopt innovative technologies to optimize seasonal floodplain productivity by cultivating fish and/or by conserving natural fish.

Length-weight relationships of fishes from tributaries of the Volta River, Ghana: Part II and Conclusion

Slopes and intercepts of length-weight relationships obtained from 37 populations from the rivers Oti, Pru and Black Volta in Ghana were compared using a one way analysis of covariance with fixed effects. Although no significant differences were obtained from this analysis, an ANOVA comparing the magnitudes of mean condition factors (Wx100/SL3) found 9 out of 37 populations significantly different at the 0.05 level. A two-way nested ANOVA using all populations combined, however, did not yield any significant differences between the three rivers.

A global protocol for monitoring of coral bleaching

Coral bleaching and subsequent mortality represent a major threat to the future health and productivity of coral reefs. However a lack of reliable data on occurrence, severity and other characteristics of bleaching events hampers research on the causes and consequences of this important phenomenon. This handbook describes a global protocol for monitoring coral bleaching events, which addresses this problem and can be used by people with different levels of expertise and resources.

Genetics of flesh quality in fish

Genetic improvement has led to substantial increase in productivity in farmed animals and in tropical fin fish, this is evident in tilapia. The GIFT (Genetically Improved Farmed Tilapia) strain of Nile tilapia (Oreochromis niloticus) has been developed by the WorldFish Centre (formerly known as ICLARM), Norwegian Institute of Aquaculture Research and national research partners from Philippines (1988-1998) and from Malaysia (2000- present).

Feasibility of adopting aquaculture without detriment to existing farming practices: a case of Bangladesh farming systems

Integrating agriculture aquaculture that would draw inputs from on farm sources is viewed as a viable option to improve the productivity, income and resource use efficiency of existing farms in Bangladesh. To assess the existing resource availability, use pattern and efficiency before introducing new aquaculture technology within the existing farm systems, a survey of 330 pond operating farm households was conducted in six selected unions from two thanas (subdistricts) of Bangladesh.

Developments in the breeding of cultured fishes.

The controlled breeding of finfish for culture is reviewed with special refer-ence to recent developments and persistent problems. Freshwater species are at present cultured on a much larger scale than brackishwater and marine species which have potential for aquaculture in arid and semi-arid lands. A reliable supply of fish seed for freshwater farming can usually be produced from captive broodstock whereas coastal aquaculture still depends largely on collection of seed from the wild.
