Overview: The restrictions of the access to Moroccan fishing grounds forced the Spanish cephalopod fleet to extend the scope of fishing agreements to other countries, first to Mauritania, from where it extended progressively to southern latitudes (Senegal, Guinea Bissau and Guinea). In these latitudes the cuttlefish species (Sepia spp.) are the main target species, with higher catches than in Mauritanian waters at this moment. Gears utilized by these freezer trawlers can be prepared either with chains (Spanish trawl) or with bobbins in the footrope (Korean trawl). The preservation of catches is frozen, what allows longer trips with an average duration of 50 to 60 days at sea. As said above, the most common cephalopod species exploited in this fishing ground is cuttlefish (Sepia spp.) although octopus catches have considerably increased during lasts years, being even higher than those of cuttlefish

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.

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 cephalopods 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 1 “Freezer, fin-fish and cephalopods 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: 9 % crustaceans 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 70 mm).
  • Vessel-related measures
    Access control: Vessel size (maximum 3 143 GT authorized tonnage per year)
  • Fishing activity-related measures
    Vessel number (3 143 GT authorized tonnage per year) and closed area (out of the fishing area established by the Agreement).

Status and Trends
 
This fishery has suffered a strong decay during the last years. Catches are relatively low and fishing coasts are significantly increasing. These facts make this fishery not profitable at this moment.
