Overview: The Spanish freezer shrimper fleet in Guinea-Bissau has oscillated and the number of vessels has been reduced along the years. Thus, in 1987, 37 vessels operated in these waters, this number diminishing until year 1997 with no fishery in the area because of the civil war. The fishery re-started in 1998, with one single vessel. Since then, the number of vessels has oscillated between a maximum of 23 in 1999 and a minimum of 12 in 2006 and 2007. The target species of this fishery is the deep water rose shrimp P. longirostris, which has constituted more than the 70% of the catches in the last ten years. The second species in the catches is the striped red shrimp A. varidens, with 14%. The southern pink shrimp F. notialis only account for the 5%, and the rest of species are represented in very small proportions.

History
 
The shelf of Guinea-Bissau, extended between Cape Roxo and Santa Ana has an extension of approximately 60 miles in its southern area. This constitutes de wider shelf in West Africa, fact that has favored the presence of foreign fleets during decades. Spanish fleet was one the fist established in Guinea-Bissau during the ‘60s. Since1986, part of the Spanish freezer bottom trawl shrimp fleet has operated in the EEZ of Guinea-Bissau with European Community licences for “shrimper trawlers”. There have been several EU-Guinea Bissau Fishery Agreements during this period, with more restrictive conditions for the fishery along the time.

Geo References for: Guinea Bissau

The marine environment of Guinea-Bissau is characterized by one of the largest continental shelves in the region, approximately, consisting of large shallow areas, large river run-off and extensive mangrove forests lining the mainland coastline and that of the Bijagós Archipelago. The coastal areas are characterized by strong currents and occasional strong winds. The Guinea-Bissau ecosystem, located at the southern limit of the Canary Current System and the western limit of the Gulf of Guinea System, is characterized by strong seasonal variations of oceanographic conditions (Berrit and Rebert, 1977). From January to February the continental shelf is marked by upwelling events. Characteristically warm and salty tropical waters dominate from May to June. With the progression of the rainy season, the intrusion of warm, low salinity inner waters tends to dominate. As a result of upwelling events and the input of organic matter from river run-off, primary productivity is relatively high in the area (Berrit and Rebert, 1977). There is a seasonal variability of the ecosystem, including a higher productivity during the dry season (Domain, 1982). The biota have adopted strategies compatible with this variability, as reflected, e.g., in feeding migrations of fish along the coast and the reproductive migration of shrimp into estuaries following the cycle of wet and dry seasons.
Vessel Type
Stern trawlers freezer
Flag State
Spain

Average characteristics during the period 1999-2006 were 27 m length, 113 GRT and 504 h.p.


Catch Handling and Processing Equipment
Freezing. Shrimps are classified onboard in 8 commercial categories depending on their size (from 0 to 8)
Crew
15-18 persons (Spanish. Mauritanian and Senegalese nationalities) (2009)
Fleet segment
Bottom otter trawl targeting crustaceans with minimum 40 mm mesh size

The fleet is exclusively composed of freezer shrimper trawlers, based at the Port of Huelva (SW Spain).
Fishing Gear
Single boat bottom otter trawls

These shrimpers usually alternate the use of outriggers and the classic bottom otter trawl with trawl doors (“baka” type), depending on the target species. Thus, outriggers are used to fish P. longirostris and F. notialis, usually during daylight hauls, while the classic bottom otter trawl with trawl doors is employed for a deeper fishery, especially targeting A. varidens and C. maritae in deep hauls usually made at night.


Seasonality

Management Regime
Fisheries Partnership Agreement between the European Community and the and the Republic of Guinea-Bissau for the period 16 June 2007 to 15 June 2011 (OJ L 342, 27.12.2007, p. 10–75). Management measures of the Spanish crustacean trawlers fishery are included in the current Fishery Agreement between the European Community and the Republic of Guinea-Bissau (OJ L 342, 27.12.2007, p. 10–75) under the fishing category 2 “Shrimp trawlers”.

This fishing agreement expired in June 2011 and has not been renewed.
Management Methods

Conservation and management measures with focus on Effort control (licences system) and catch control

  • Aquatic species-related measures
    Limitation of by-catches: 50% of fishes and cephalopods by fishing trip
  • Gear-related measures
    Gear type (doubling of the cod-end’s netting yarn, whether single or multiple, prohibited; methods or devices may be used to seek to obstruct the mesh of the nets or reduce their selective effect prohibited) and mesh size (minimum 40 mm).
  • Vessel-related measures
    Access control: Vessel size (maximum 1 421 GT authorized tonnage per year)
  • Fishing activity-related measures
    Vessel number (1 421 GT authorized tonnage per year) and closed area (out of the fishing area established by the Agreement).
Related Fisheries - Fishing activity(ies) managed under the same management unit or being ruled by the same fishing agreement

Status and Trends
 
The yields of the target species, P. longirostris, have kept relatively stable during the last ten years. An increase in yields and catches has been detected in 2008.
