  abstract = {{F}rench {M}editerranean lagoons are frequently subject to shellfish contamination by {D}iarrheic {S}hellfish {T}oxins ({DST}s) and {P}aralytic {S}hellfish {T}oxins ({PST}s). {T}o predict the effect of various environmental factors (temperature, salinity and turbidity) on the abundance of the major toxins producing genera, {D}inophysis and {A}lexandrium, and the link with shellfish contamination, we analysed a 10-year dataset collected from 2010 to 2019 in two major shellfish farming lagoons, {T}hau and {L}eucate, using two methods: decision trees and {Z}ero {I}nflated {N}egative {B}inomial ({ZINB}) linear regression models. {A}nalysis of these decision trees revealed that the highest risk of {D}inophysis bloom events occurred at temperature < 16.3 degrees {C} and salinity < 27.8, and of {A}lexandrium at temperature ranging from 10.4 to 21.5 degrees {C} and salinity > 39.2. {T}he highest risk of shellfish contaminations by {DST}s and {PST}s occurred during the set of conditions associated with high risk of bloom events. {L}inear regression prediction enables us to understand whether temperature and salinity influence the presence of {A}lexandrium and affect its abundance. {H}owever, {D}inophysis linear regression could not be validated due to overdispersion issues. {T}his work demonstrates the tools which could help sanitary management of shellfish rearing areas.},
