  abstract = {{T}he presence of harmful microalgae in aquaculture sites represents a risk for production and human health, so surveillance of these species is relevant for early warning of harmful algal blooms. {H}ere we examine the monitoring results of potentially toxic phytoplankton in {P}eruvian coastal sites associated with the cultivation of {A}rgopecten purpuratus and natural banks of other mollusks. {W}e evaluated the density, frequency, temporal and spatial distribution of these species, as well as blooms occurred from 2011 to 2019. {R}esults showed that the most abundant species was {H}eterosigma akashiwo, and the most frequent ones were {P}seudo-nitzschia delicatisima and seriata complexes. {T}he majority of blooms were caused by {H}. akashiwo (21 events) and {D}inophysis acuminata (19 events). {C}anonical correspondence analysis revealed the preference of dinoflagellates to warmer sea surface temperatures and more stable conditions (indicated by low wind velocities) than {P}seudo-nitzschia species. {G}eneralized additive models ({GAM}s) indicated that wind velocities > 3.7 m s-1 and {E}l {N}in similar to o conditions favor {P}seudo-nitzschia species while warm temperatures (> 20 degrees {C}), weaker winds (< 3.7 m s-1), and cold periods associated with {L}a {N}in similar to a promoted higher densities of {D}. acuminata complex. {A} recent increasing trend in the density of {D}. acuminata was observed. {T}his information is useful to understand the dynamics of potentially toxic species in upwelling regions.},
