Resumo: 	Six batches of king scallop juveniles of different origins and obtained either by collection in their natural habitat (Saint-Brieuc, Scotland, Ireland), or by hatchery production in Brest in 1981, 1982, 1983, have been sown, at a size of 3 cm, in the roadsted of Brest between 1977 and 1983. Their growth, strongly linked to the evolution of the temperature, is well-described by a model, including a sinusoidal modulation, by Von Bertalanffy. The growth of the scallops collected in Saint-Brieuc, Scotland and Ireland, differentiates from that of the individuals from their original area and shows similarities with that of the scallops produced in Brest. Consequently, there must be an adaptation of the growth to the environmental conditions of the roadsted of Brest. Hatchery scallops, with an average length of 107 mm and a Von Bertalanffy K of 0.7, show a growth pattern which is similar to that of the natural populations they are from. From a practical point of view, the commercial size (length of 102 mm) is reached two years after the sowing, which makes the king scallop a very interesting species for seabed farming.
