Book (stand-alone)Report of the Fisheries and Biological Data Preparation Workshop on the Shrimp and Groundfish Fisheries of the North Brazil Shelf Large Marine Ecosystem 2019
Also available in:
No results found.The Fisheries and Biological Data Preparation Workshop for the Shrimp and Groundfish Fisheries of the North Brazil Shelf Large Marine Ecosystem (NBSLME) was held in Bridgetown, Barbados 23-25 October, 2018. The meeting brought together 14 participants including fisheries officers, government organizations and FAO. The main objective of the workshop was to provide training on data preparation for stock assessment purposes and fisheries status/trends monitoring, enhance capacities in fisheries data and statistics collection at the national and sub-regional levels, and review status of data collection for the shrimp and groundfish fisheries of the NBSLME. The current state of the Fisheries and Resource Monitoring System (FIRMS) stocks and fisheries inventories for the NBSLME was reviewed and updated with inputs from participants. Ongoing work on the Data Repository and Decision Support System (DSS) for the Caribbean and North Brazil Shelf Large Marine Ecosystems (CLME+) Project and its application in the NBSLME was presented and discussed. A template for recording fisheries and biological data of key species in the NBSLME for stock assessment purposes was reviewed by participants. Furthermore, for each country and fishery, participants reviewed availability of data including, inter alia, time series of landings and fishing effort, length frequencies and socio-economic information. Additionally, a review was made of the biological parameters (e.g. length-weight relationship, growth, maturity) available for key shrimp and groundfish species in the NBSLME and data gaps identified. Information on genetic studies on shrimp and groundfish species in the NBSLME region served as background for discussion on the stock structure -
Book (series)Life cycle assessment of southern pink shrimp products from Senegal. An environmental comparison between artisanal fisheries in the Casamance region and a trawl fishery based in Dakar. 2009
Also available in:
No results found.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.
