Landing data from 1999 to 2009, considered as an abundance index, remotely sensed thermal data (sea surface temperature, SST from AVHRR Pathfinder V5) and a temporal variable (month) were used to construct the models. The results from this work suggest that high abundance of round sardinella and anchovy was closely related to SST. High abundances of round sardinella and anchovy were associated with different temperature ranges, 21.0 to 25.0 °C and 22.0 to 23.0 °C, respectively. However, temperature corresponding to the highest abundance of round sardinella and anchovy were very close (22.7 °C and 22.3 °C respectively). Indeed, it might exist an optimal temperature window for these two species in Senegalese water might exist. specialized POISSON MARIN ESPECE COMMERCIALE ESPECE PELAGIQUE SARDINE ABONDANCE TEMPERATURE DE SURFACE EFFORT DE PECHE MODELISATION VARIATION SAISONNIERE ANCHOIS SENEGAL ATLANTIQUE 036MILMAR01 040PECHE03 31 2 9-17 2015 0212-5919 https://www.documentation.ird.fr/hor/fdi:010064315 0212-5919 [F B010064315] https://www.documentation.ird.fr/hor/fdi:010064315 https://www.documentation.ird.fr/intranet/publi/depot/2015-03-30/010064315.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2015-03-30 2024-01-05 fdi:010064315 fre
