Synopsis (short abstract) Life cycle assessment (LCA) of two Senegalese seafood products exported to Europe has been undertaken based on the functional unit of one kilogram of product (frozen whole shrimps, independent of size) plus the accompanying packaging at the point of import to Europe, i.e. transported by boat to Vigo, Spain. The products are exchangeable on the European market, but the way they reach this market from the fishery over processing is very different. One product is produced through on-board p rocessing on demersal trawlers based in Dakar fishing at sea in FAO fishing zone 34 (eastern central Atlantic), then landed and stored before being exported to Europe. The other product originates in artisanal fisheries in the Casamance River in southern Senegal. Fishing takes place to similar extents by the two fishing methods: Mujas, a fixed trawl set in the deepest part of the river from a canoe, and Félé-félé, a type of driftnet managed by three men in a canoe. The shrimps are land ed and transported to a processing plant in Ziguinchor where they are washed, packed and frozen before land transportation to Dakar, storage and finally shipment to Europe. The three fisheries included (trawl, Mujas and Félé-félé) were shown to have highly different catch compositions. Each fishing method has advantages and drawbacks from a biological point of view, i.e. proportion of discard, landed bycatch and small shrimps in the catch. LCA results showed major differences between the two final products, with regard to resource use and environmental impact, depending on their origin. For the product originating in trawling, fishing was the most important activity in all categories of environmental impact. For the product originating in the artisanal fishery, fishing was the most important activity from a biological point of view. In contrast, processing and storage dominated the two categories: global warming and ozone depletion potential. The main areas to improve regarding these categories in the production chain of the trawled product are the use of fuel and refrigerants on board, while the main areas for improvement in the chain of the artisanal product are the use of energy and refrigerants in the processing plant and the energy source used by the plant. Both on board the trawlers and in the mainland processing of artisanal shrimps, considerable amounts of refrigerants with a high global warming and ozone depletion potential are used to fre eze the shrimp products. In both chains, transportation was found to be of minor importance. Increased traceability and labelling is also desirable to enable active consumer choices between products.

Development strategy during the 196O and 1970s was based on the philosophy that Developing countries lacked improved technology and capital for speeding up their development industrialization was promoted in order to capitalize on the abundant fish resources. However. the anticipated expansion of the economy did not happen and the development approach shifted towards an integrated rural strategy where emphasis is put on the community as a whole to upgrade incomes and the quality of lif e through technical assistance and the active participation of fisherfolk and the community.

With financial assistance from Denmark and Norway, and in collaboration with the Peoples Republic of Benin, the Fisheries Department of FAO is implementing in West Africa a programme of small scale fisheries development,commonly called the IDAF Project.This programme is based upon an integrated approach,involving production, processing and marketing of fish, and related activities;it also involves an active participation of the target fishing communities. This report is e working paper and the c onclusions and recommendations are those considered appropriate at the time of preparation, The working papers have not necessarily been cleared for publication by the government (s) concerned nor by FAO.They may be modified in the light Of further knowledge gained at subsequent stages of the Project and issued later in other series. The designations employed and the presentation of material do not imply the expression of any opinion on the part of FAO or e financing agency concerning the le gal status of any country or territory, city or area, or concerning the determination of its frontiers or boundaries.
