This species follow the r selection theory i.e. low cost for reproduction, short lived fish, large number of offspring at a time, low offspring survival and no parental care; thus they are sensitive to climate fluctuation which impact their pelagic habitat. A monthly data base started from 1995 to 2011 have been compiled by the CRODT mixing landing site sampling with some data collected in situ using fisheries research vessel. The relationship between LT and LF is linear and appear as consistent, which allow future integration of other basis using different metric for fish individual size. From this basis, we analyse the change in individual fish size spectra, their sex ratio, maturity stage and gonadal somatic index as well as the condition factor. The change, are scrutinized per size class and geographical location associated to different pelagic habitat in Senegal. specialized AFRIQUE DE L'OUEST SENEGAL ATLANTIQUE 034BIOVER01 040PECHE PREFACE-PIRATA-CLIVAR Tropical Atlantic Variability Conference, Cape Town (ZAF), 2015/08/25-27 68 [s.l.] IRD 2015 https://www.documentation.ird.fr/hor/fdi:010091472 [F B010091462] https://www.documentation.ird.fr/hor/fdi:010091472 https://horizon.documentation.ird.fr/exl-doc/pleins_textes/2024-08/010091472.pdf IRD - Base Horizon / Pleins textes 2024-07-11 2024-08-07 fdi:010091472 fre
