Resumo: | In the 1960s, with a drop in the king scallop stock, the clam became a substitution resource with productions of over 400 tonnes. The drop in the production until the disruption of the fishery in the 1980s is the combined consequence of the increase of the fishing capacities with an unfavourable populating demographic strategy. Large deposits are fairly rare. In 7 years, only one age group, born in 1971, withstood the fishery. Many age groups of satisfactory abundance, from the end of the 80s on, combined with a total disruption of the fishery for a few years, lead to a recovery of the stock with fishing levels equivalent (today) to those of the 1950s. The clam, though less iconic than the king scallop in the local context, has now been for a number of years the more important species of the Roadstead of Brest in terms of turnover, and thus deserves to be closely looked at.
