Chlorpyrifos is the most used insecticide in Argentina. Cnesterodon decemmaculatus is a widely distributed, endemic fish from Neotropical America. It attains high densities in the shallow water assemblages of Argentina and Brazil. The aim of this study was to assess the acute toxicity of chlorpyrifos to C. decemmaculatus. The mean 96-h LC50 of three independent determinations was 105.3 (±3.1) µg/L. Sublethal effects were observed. Swimming behavioral changes at each chlorpyrifos expositions were reported. C. decemmaculatus represents a good model for ecotoxicological risk assessment.
