  abstract = {{T}he study of the distribution of eggs and fish larvae between cold ({M}ay end of upwelling season) and warm ({N}ovember beginning of upwelling season) seasons along the {S}enegal-{G}ambia maritime zone was carried out using ichthyoplankton data. {T}he data were collected between 0 and 50m depth using a multinet of 80 ?m mesh during ecosystem cruises aboard the {N}orwegian vessel {F}ridtjof {N}ansen in {N}ovember 2011 and {M}ay 2012. {T}he sampling scheme consisted in oblique tow, and covered the continental shelf of {S}enegal-{G}ambia area. {I}n laboratory, 36 samples were analyzed and the fish eggs and larvae were identified by microscopy to the family and counted, using appropriate identification keys. {A}nalysis of eggs abundance shows dominance of {S}paridae with 14% and low abundance of {M}yctophidae (4%) and {C}lupeidae (3%) during the warm season ({N}ovember). {C}onversely, {M}yctophidae eggs were dominant in the cold season ({M}ay (45%)) followed by {C}arangidae (34%). {F}ish larvae were dominated by the {C}lupeidae (52%), followed by the {M}yctophidae (19%) in warm season ({N}ovember). {I}n {M}ay (cold season), the larvae of these two families were still dominant, but with higher proportions for {M}yctophidae (29%) and lower for {C}lupeidae (23%); {S}paridae larvae were also fairly well represented (19%). {A}t the spatial level, during the warm season, an area of high eggs concentration was founded between the south of the {C}ap-{V}ert {P}eninsula and the {G}ambia. {D}uring the cold season, two areas of high concentrations were observed, located off {K}ayar and off the mouth of the {C}asamance {R}iver, respectively. {O}n one hand, an area of high larval concentration was identified at the mouth of the {C}asamance {R}iver in {N}ovember. {O}n the other hand, during the cold season, high concentrations were noted off the entire study area, with higher concentration off the {C}ap-{V}ert peninsula. {T}he study allowed, within its limits, the spatial and temporal location of critical habitats, where environmental conditions are more favorable to the retention of eggs and larvae as well as for their feeding. {S}uch results are of relevant interest for conservation of resources and fisheries management.},
