Pelagic fish (except for tuna) are landed in Sierra Leone mainly by the artisanal fishermen. The two most important species are Sardinella and Ethmalosa.Deep-sea species are normally exploited by purse seiners of foreign countries. The landings of artisanal fishermen largely comprise Sardinella eba.Landing data for Sardinella landed at Tombo and Goderich, and for Ethmalosa at Tombo, are presented in tabular form. Collection methods are described, with a definition of the unit of fishing effort, and a description of the gear used.The landing data are discussed with particular attention to fishing effort, catch per unit effort, and price per ton

The objective of this short project progress report is to investigate, in a catchment on which earlier nitrate data are available for comparison, seasonality and budgets, in relation to land use, of nitrate inputs, concentrations and loads. Sampling was undertaken from 1984-87 in the River Frome catchment and data on nitrate concentrations analysed.

The objective of this short project progress report is to investigate the possible water quality implications of modern watercress growing practices. Chalk receiving watercourses are usually of high supply, amenity, game fishing and fish farming value. Any headwater pollution load, therefore, needs characterising and quantifying. Two sites of watercress farming were studied in 1986-87 and nutrient levels examined. Different approaches of watercress farmers in Dorset and Hampshire are summarised.

In 1996 a Strategy for the Management of Salmon in England and Wales was launched by the National Rivers Authority setting out objectives for the management of Salmon fisheries. These objectives are to be met through local Salmon Action Plans which are to be produced for each of the 68 principal salmon rivers in England and Wales by December 2003. A consultation document was produced for the river Wyre and released publicly during October 2003. This document: • Determined an egg deposition figure of 1.27 million eggs which would allow maximum gain from the fisheries • Raised a number of issues which are though to limit existing salmon production. • Identified actions which may be undertaken by the Environment Agency and other bodies to improved stocks. The document looks at the issues in the consultation document and also highlights some important changes to historic egg deposition rates following further analysis of the data. Some of the major issues addressed in the plan are: • Severe low flows on specific tributaries • Reduced juvenile production caused by insufficient habitat. • Changes in flow regime resulting in the wash out of gravels and redds. • The impact of man made structures preventing access to suitable spawning areas, and preventing the downstream distribution of spawning gravels.

Fishing communities around the Indian Ocean were severely affected by the December 2004 tsunamis. Programs for rebuilding coastal fisheries livelihoods need to address the pre-tsunami situation that was characterized by overfishing and degraded natural resources. Adopting appropriate strategies to ensure sustainable livelihoods will require community involvement, as well as cross-sectoral, integrated planning and management at ascending government levels. Key recommendations from the WorldFish Center study Sustainable Management of Coastal Fish Stocks in Asia are presented to encourage discussion and debate.
