Sumario:The aim of this study was to analyse the effect of high density for Manila clams at the first ongrowing stage under netting in ground plots, in order to establish an economical improvement for clam farming. The intensive clam cultivation was maintained to the competence size at high density (6 000 indiv/m²), when the effects of density on mortality and growth begin. A total of 97 000 units of Manila clams Ruditapes philippinarum (Adamsampersand Reeve, 1850), prefattened in a raft with air-lift (10 mm length), was sown in two batches at different densities: 1) 1 500 indiv/m² in a plot of 22 m ˟ 1,5 m, and 2) 6 000 indiv/m² in a plot of 10 m ˟ 1,5 m. The culture was continued through ongrowing until competence size, which was of 20 mm.
