Abstract
During November 2006 on a 500 m long experimentally placed ''Christmas tree'' rope collector for juvenile mussels (Mytilus galloprovincialis Lamarck, 1819) placed the previous year a significant number of juvenile fan mussels (Pina nobilis Linnaeus, 1758) were observed. Live juvenile individuals (N=322) of P. nobilis with shell length from 17 to 93 mm were found in two sampling events. All juvenile fan mussels were found exclusively on deeper parts of the mussel rope. Observed population density was from 6 to 43 individuals per meter of the rope collector. The 120 smallest juveniles of P. nobilis were separated for the purpose of monitoring the growth rate in suspension, and the remaining juveniles were placed in the natural environment.
