Spain Bottom trawl octopus and cuttlefish fishery - Senegalese watersThe Senegalese EEZ is dominated by several cyclonic gyres, including the Guinea Dome at 10ºN, 20ºW, driven by the North Equatorial Counter Current (Tomczak and Godfrey, 1994). Because the cyclonic rotation induces upwelling (doming of the thermocline), these features are more productive than the surrounding waters. The productivity of the Senegalese waters is high during winter, as a result of river run-off after the rainy season, localized upwelling, and cyclonic eddies retaining productive waters. Around May, the hydrographic conditions off Senegal become less favourable, with SST rising towards ca. 25ºC, stratification of surface water, and decreasing food availability (Zeeberg et al., 2008). The upwelling starts on the Senegalese continental shelf inducted by trade winds from November to January. Then, it extends from the North to the South coast, with a maximal intensity in March-April. Along the North coast, the upwelling localizes around Saint Louis, being extremely coastal and with maximal intensity in December-March. This marked seasonality of upwellings and the latitudinal displacement through the Mauritanian and Senegalese coasts produce important changes in the structure of the biological communities. In short periods (weeks), the system can alternate from a warm equatorial phase to a cold subtropical phase, this deriving in an alternated dominance between tropical and templates communities (Meiners, 2007).

Management Regime
Council Regulation (EC) No 2323/2002 of 16 December 2002 on the conclusion of the Protocol setting out the fishing opportunities and the financial contribution provided for by the Agreement between the European Economic Community and the Government of the Republic of Senegal on fishing off the coast of Senegal for the period from 1 July 2002 to 30 June 2006 (OJ L 349, 24.12.2002, p. 46–65). Management measures of the Spanish cephalopods bottom trawl fishery in Senegalese waters were included in the Fisheries Agreement between the European Community and the Republic of Senegal. After the end of the last Agreement (OJ L 349, 24.12.2002, p. 46–65) the Spanish fisheries in Senegalese waters were closed. Management measures described below are those included in this last Fishery Agreement.
Management Methods
Conservation and management measures with focus on Effort control (licences system) and catch control.
