Code Division name Percentage
34.1.1 Morocco coastal 7.6%
34.1.3 Sahara coastal 7.5%
34.3.1 Cape Verde coastal 10.1%
34.3.3 Sherbro 7.5%
34.3.4 Western Gulf of Guinea 10.9%
34.3.5 Central Gulf of Guinea 15.2%
34.3.6 Southern Gulf of Guinea 15.6%
Clupeoids and other pelagic fishes dominate catches in the two northern coastal divisions. Significant catches of molluscs, mainly cephalopods.
Division 1.3 - Sahara coastal
Division 3.3 - Sherbro
Catch trends in three central divisions are still influenced by the fluctuations of clupeoids but coastal and demersal fishes begin to have a greater importance.
Division 3.4 - Western Gulf of Guinea
In two remaining coastal divisions, all the groups of species are fairly well represented. Maybe this is a sign of more varied and stable marine ecosystems, which have supported a more steady rise of catches throughout the last 30 years, although the distribution and abundance of important fishery resources have varied (Koranteng,1999).
Division 3.6 - Southern Gulf of Guinea
