  abstract = {{T}his study investigates the effects of tidal cycles on the zooplankton community within the {C}otonou {C}hannel, an important waterway connecting the large {N}okou{\'e} {L}agoon to the {A}tlantic {O}cean in {B}enin. {F}rom the determination of zooplankton composition from 25-hour samples collected in {J}uly 2020, alpha diversity indices and abundance were assessed, while relationships between biotic and abiotic parameters were analyzed through {P}earson correlation, analysis of variance, and principal component analysis. {A} total of 66 zooplankton taxa were identified, with rotifers exhibiting the highest species richness (35 taxa), while copepods dominated in abundance (71%). {Z}ooplankton abundance varied significantly, ranging from 2 to 95 ind {L}-1 depending on the tidal phase. {A} negative correlation was found between species richness (r = -0.51, p < 0.01) and increasing salinity (3-37), indicating that higher salinity reduced diversity (r = 0.06, p > 0.05). {R}esilient species like {S}ynchaeta bicornis persisted despite salinity changes. {T}he tidal cycle structurally altered the zooplankton community, with abundance and diversity peaking at different phases, notably higher at high tide (15 ind {L}-1.) {T}hese initial findings underscore the complex interactions between tidal dynamics and estuarine biodiversity, suggesting the need for further research across different tidal and seasonal conditions to inform effective management and conservation efforts.},
