| An area located between the Mont-St-Michel Bay and Jersey was monitored from 1984 to 1985. Limpet densities have been evaluated through quantitative sampling and underwater video. At the same time, some planktonic samplings have enabled the monitoring of the evolution of larval abundances. Maxima, planktonic and benthic density areas superpose each other. Moreover, the study of the populations shows that the number of young colonies is increasing, thus clearly indicating that Crepidula fornicata populating is booming in the Norman-Breton gulf. |
