“…It is well known that the highly dense multilayered disposition of mussels can lead to space and food limitations (Okamura 1986, Fréchette et al 1992, Alvarado and Castilla 1996 and to self-thinning as the individuals grow (Hughes and Griffiths 1988, Fréchette and Lefaivre 1990, Fréchette and Lefaivre 1995, Petraitis 1995, Guiñez and Castilla 1999, Guiñez et al 2005. However, despite that several authors have analyzed ST in mussel populations (Hughes and Griffiths 1988, Fréchette and Lefaivre 1990, Petraitis 1995, Fréchette et al 1996, Guiñez and Castilla 1999, Alunno-Bruscia et al 2000, Alunno-Brusciaet al 2001, Filgueira et al 2008) some aspects of the biomass/massdensity relationships need to be revised.…”
