It was recorded in all the five selected stations, the presence of four species of Vibrio namely, Vibrio parahaemolyticus, Vibrio cholerae, Vibrio fluvialis and Vibrio alginolyticus whose highest abundance reached 5.65, 6.26, 4.9 and 4.83 log CFU/100 ml respectively. Vibrio cholerae was the most isolated during the study with a frequency of 65%. The abundance dynamics of these germs is strongly influenced by nitrates, salinity, dissolved carbon dioxyde (CO 2) and ammonium ions (NH 4 +). The visualization of corrgram shows high degree of association between studied parameters. We note a coefficient of determination r 2 = 0.50 for the multiple linear regression model for Heterotrophic Aerobic Bacteria (HAB) and a coefficient of determination r 2 = 0.58 for the MLR model for V. cholerae. The physicochemical parameters explain at 43% (r 2 = 0.43) the distribution of the abundances of V. parahaemolyticus, at 45% (r 2 = 0.45) the distribution of abundances of V. alginolyticus and at 26% (r 2 = 0.26) for V. fluvialis. %G English %2 https://hal.science/hal-03865466/document %2 https://hal.science/hal-03865466/file/Tamsa%20Arfao%20et%20all.%20AJMR%202021.pdf %L hal-03865466 %U https://hal.science/hal-03865466 %~ SDE %~ PRES_CLERMONT %~ CNRS %~ LMGE %~ GIP-BE %~ ACL-SVSAE %~ TEST3-HALCNRS
