To inform the development of alternative livelihoods, the women's traditional alok fishery in the Campo-Ma'an National Park and buffer zone of southern Cameroon were studied over 15 months. Participatory rural appraisal was used to characterise livelihood strategies among 45 households. Thirty-three cultured crops, nine farmed animal species and 65 non-timber forest products, including 31 bushmeat species are cultivated in, or harvested from, the forest. Transport is a major impediment to commercial trade of all local products.
An examination is made of the literature on giant clam (Tridacna ) culture methods induced spawning, larvae, larval and post-larval rearing and socioeconomics. ASFA and the ICLARM library and professional staff collections were used for the search.
The findings are presented of a search conducted on traditional fishing gear design and construction using the ASFA database (1971-90) and the ICLARM Library and professional staff collections.
The wetlands of the Yellow River delta face a situation common in many developing countries where the quest for rapid economic growth brings development to the doorstep of natural ecosystems and threatens their health and survival. This brief examines the several issues relating to wetlands in the Dongying municipality. Can the wetlands in Dongying coexist with the modern development that is creeping towards them? Is there sufficient appreciation that these wetlands are worth caring for?
The chapter begins with an overview of the water system in the Congo Basin, presents a synopsis of select hydrological goods and services, describes the relationship between forests and water resources in large river systems and concludes with a section on the state of knowledge and water resource management in Central Africa.
This paper highlights the importance of fisheries and aquaculture in management of the world’s water resources. It underlines the value of these resources and the critical importance of managing water quantity and quality for fisheries and aquaculture as well as for other human uses. This will require more holistic approaches to water management and the effective governance systems these require.
Issues concerning the promotion of wastewater reuse in aquaculture are re-examined in this article.
A critical first step in understanding vulnerability in inland fishing communities is to move away from classical fishery definitions that consider only the resource and harvest methods and, instead, recognize that fisheries operate across broad domains including the natural resource and its ecosystem, people and livelihoods, institutions and governance systems, and external drivers.
In this study, length-frequency data on Spanish sardine (Sardinella aurita) from northeastern Venezuela were analyzed for the period 1967-1989. Average growth parameters for the von Bertalanffy equation were established as L sub( infinity )= 26.6 cm (TL) and K = 1.26 year super(-1). The number of recruits to the fishing area, estimated from length-structured Virtual Population Analysis, varied from <10 super(8) in the late 1960s to >10 super(9) at the end of the 1980s.
Although the precise origins of visioning are unclear, it is a widely used tool for defining stakeholder aspirations and a vision of the future in the context of a development intervention.
