Overview: The fishery targeted the deep water rose shrimp P. longirostris, which constituted the 57% of the catches during the period 1998-2007. A. varidens accounts for the 10%, while a mixture of other crustaceans does it for the 26%. Finfish and cephalopods only constituted the 6%, both together. These shrimpers used to alternate the use of outriggers and the classic bottom otter trawl with trawl doors (“baka” type), depending on the target species. Thus, outriggers were used to fish P. longirostris usually during daylight hauls, while the classic bottom otter trawl with trawl doors was employed for a deeper fishery, especially targeting A. varidens in deep hauls usually made at night. This Spanish shrimp fishery in Guinean waters was closed in 2008, at the end of the Agreement for the period 2004-2008. Last fishery agreement, signed in 2009, does not include this type of fishery

History
 
The Spanish shrimper fishery started in Guinea in 1995. It continued until 2008, through fishing agreements between the Republic of Guinea and the EU. The fleet was quite reduced, with a maximum number of 10 vessels in 2004. These vessels operated intermittently in Guinean waters, usually sharing EU licences with other countries as Guinea Bissau, Senegal or Mauritania.
Fishing Activity
Type of production system: Commercial; Industrial   

Fishery Area
Climatic zone: Tropical.   Bottom type: Soft bottom.   Depth zone: Shelf (50 m - 200 m); Slope (200 m - 1000 m).   Horizontal distribution: Neritic.   Vertical distribution: Demersal/Benthic.  

Geo References for: Guinea

The Guinean EEZ is located in the inter-tropical zone and it is subjected to the existence of two main seasons that depend on the winds and rainfalls regimes (Morize, 1997). The Guinean continental shelf is seasonally impacted by several processes that contribute to its enrichment. On one hand, the north western area is influenced by waters from the Mauritanian-Senegalese upwelling system, induced by different water masses supplied by the Canary Current and the trade winds, that leads to a high biotic production during the dry season. This upwelling is very active in the North from January to May, but weakens from June to November. On the other hand, the coastal area is influenced by terrigenous supplies transported by rain, after being reshuffled or not in the mangroves (Morize, 1997; Colomb & Le Fur, 2002; Diallo et al., 2004). Both enrichment processes contribute to a high biological diversity and important biomasses of plankton, invertebrates and commercial fishes (Diallo et al., 2004). The great extensions of mangrove areas, the rain intensity and the alternation of the dry and rainy seasons are the main factors contributing the concentration of great fish richness in the coastal fringe between 0 and 12 miles (Domain, 1989; Fontana and Morize, 1995).
Resources Exploited

West African geryon - Gulf of Guinea
Other resources: Stock of deep water rose shrimp Guinea Bissau-Guinea, aristeidae, plesionika shrimps
Vessel Type

Flag State
Spain

Average characteristics during the last years of the fishery (period 1999-2006) were 26 m length, 99 GRT and 403 h.p.
Catch Handling and Processing Equipment
Freezing. Shrimps were classified in commercial categories (from 0 to 8), depending on their size.
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 was 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 were used to fish P. longirostris usually during daylight hauls, while the classic bottom otter trawl with trawl doors was employed for a deeper fishery, especially targeting A. varidens and C. maritae in deep hauls usually made at night.
Seasonality
All year long, some vessels combining with other fishing grounds
Trip Duration
30-90 fishing days

Legal definition
Shrimp trawlers
Management Regime
Last legal definition was the Fisheries Partnership Agreement between the European Community and the Republic of Guinea for the period 1 January 2004 to 31 December 2008 (OJ L 127, 29.04.2004, p. 31-32). Management measures of the Spanish shrimp fishery were included in the Fishery Agreement between the European Community and the Republic of Guinea-Bissau (OJ L 127, 29.04.2004, p. 31-32) into the fishing category “shrimp trawlers”.
Management Methods

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

  • Aquatic species-related measures
    Limitation of by-catches: 15% of finfish and 10% cephalopods of the total catches
  • Gear-related measures
    Mesh size (minimum 40 mm).
  • Vessel-related measures
    Access control: Vessel size (1 500 GRT per month, averaged over the year for Spain)
  • Fishing activity-related measures
    Access by nationality, licences (renewable licences, for periods of 3, 6 or 12 months), vessel number (1 050 GRT per month, averaged over the year for Spain) and closed area (in waters into 10 nautical miles from the coast-line).

Status and Trends
 
The fishery was closed at the end of the Agreement in 2008. The last fishing agreement signed with Guinea in 2009 does not contemplate this fishery.
