As V. parahaemolyticus enumerations in this monitoring corresponded to salinity values ≥29 ppt, this latter result is consistent with the observations of previous studies indicating a nonlinear relationship between vibrio populations and salinity over wide ranges (Deepanjali et al., 2005; DePaola et al., 2003), with V. parahaemolyticus densities increasing with salinity up to an optimal point (24–25 ppt) and then decreasing beyond the optimum level (FDA, 2005).
