Abstract

DIANKHA, Ousmane; SOW, Bamol Ali; THIAW, Modou  and  GAYE, Amadou Thierno. Seasonal variability of sea surface temperature, chlorophyll-a and Ethmalosa fimbriata abundance off the coast of Senegal. RGCI [online]. 2013, vol.13, n.4, pp.491-497. ISSN 1646-8872.  https://doi.org/10.5894/rgci421.

The seasonal variability of Ethmalosa fimbriata abundance off Senegal Coastal Waters was investigated using an observation sea surface temperature (SST) and chlorophyll-a (Chl-a) concentration from PATHFINDER and SeaWiFS satellites’ data of 1999-2009. The results showed that the variability of E. fimbriata landings in Senegalese waters is related to environmental changes. The seasonal fluctuations of E. fimbriata landings off Senegal Coastal Waters seemed to be governed by the combined effect of SST and Chl-a. However, SST better explains the seasonal variations of E. fimbriata landings than Chl-a, when they are used separately.

Keywords : Chlorophyll-a; Ethmalosa fimbriata; Sea surface temperature; Senegal.
