The paper by Alvarez et al. (2011) describes the use of a hydrodynamic numerical model to study the dispersion and sedimentation of particles at 2 points in Bahía Anegada (Argentina). This study is aimed to study the role of Crassostrea gigas as an invasive species. It is concluded that the particles liberated at those points do not represent a risk to the adjacent littoral zone. We consider that the article lack an adequate presentation of objectives, methods, and over the entire hydrodynamic model is not well validated. These factors undermine substantially the conclusions obtained.

Key words:   Numerical modeling, lagrangian tracers, validation
