Conteúdo:

Growth of Perna perna (L.) mussel seed from different origins (collectors and two natural
stocks) was compared using a culture system near Ratones Grande Island, SC - Brazil. The experiment occured between April and September 1998, with monthly measurements of shell lenght. Mussels from collectors grew faster than mussels from natural stocks (p<0,05). Mussels from collectors reached shell lenght of 71,1 mm in five months of cultivation, with a mean initial lenght of 31,8 mm ± 1,2. At the fifth month 57% of the population from collectors reached the comercial size (7 cm). Observed growth was comparable to the data published. Water temperature and salinity ranged within the optimum of the species. The use of collectors is recommended in order to avoid unsustainable exploitation of the natural stocks.
