This report is a compilation of five regional reviews that document the global status of tropical rivers and inland fisheries in three continents: Latin America, Africa and Asia. It explores the role of valuation methods and their contribution to policy making and river fishery management.
The parameters a and b of length-weight relationship of the form W = aLb were computed for 122 species from graphs presented in R.van der Elst's "Guide to the Common Sea Fishes of Southern Africa".
The diet of marine animals is usually determined by stomach content analysis. Although partially digested prey fragments can often be identified to species level, it is difficult to estimate the original mass of the prey organism. This information, however, is essential for calculating both the total food intake as well as the relative contribution of each prey item.
A review of case law and other documentation of human rights issues in fishing communities highlights forced evictions, detention without trial, child labour, forced labour and unsafe working conditions, and violence and personal security, including gender-based violence, as key areas of concern. We argue that human rights violations undermine current attempts to reform the fisheries sector in developing countries by increasing the vulnerability and marginalization of certain groups.
This paper presents an evaluation of the 15-week course on Training in Fisheries Planning and Management being offered at the University of Namibia since 1991. This course includes instruction in fisheries technology, fisheries biology, fisheries law and law of the sea, fisheries economics, fisheries sociology, environment impact assessment, planning and management, the logical framework approach to planning and computer literacy. The participats in the course have rated the various elements in a range of 2.9 to 4.7 out of a maximum of 5 points.
South Africa's marine resources are essentially fully exploited and in some cases over exploited. The Government of National Unity has embarked on the ambitious Reconstruction and Development Programme (RDP) to: meet the basic needs; develop the country's human resources; build economy; and democratize the state and society. Although fisheries can only be expected to play a minor role in contributing to RDP, the Programme have a role to play in managing South Africa's living marine resources.
This contribution presents von Bertalanffy growth parameter estimates for 28 species of marine fishes derived from growth curves in R. van der Elst's "Guide to the Common Sea Fishes of Southern Africa".
The promotion of integrated aquacultureagriculture has been achieved through collaborative efforts of the Malawi Government, WorldFish Center (formerly ICLARM) development partners (principally Germany and U.S.A.) and NGOs. The basic principle of integrated agro-pisciculture is to grow fish in waterbodies that are closely integrated into, and intentionally make use of the resource flows of all the diverse activities on a farm.
During the last decade the co-management concept has gained increasing acceptance as a potential way forward to improve fisheries management performance. It has, however, at the same time become increasingly evident that the co-management concept is not clearly defined and means very different things to different people.
