Abstract

Mussel farming is an alternative activity exerted by Brazilian families so as to reduce the extraction and pressure  on natural mussel populations. The objective of this investigation was to characterize the distribution of the different seed  sizes of the mussel  Perna perna on a rocky shore of Piúma, Espírito Santo State and to evaluate its use in aquaculture  projects. The study was conducted at Instituto Federal do Espírito Santo–Campus de Piúma, where 16 samples were  analyzed according to four treatments: T1 - origin of the seeds in the shore; T2 - 1 meter below the origin; T3 – 2 meters  below; T4 - 3 meters below, with four replications in a completely randomized design. Heterogeneity in vertical distribution  of the amount of seeds in the ranges 1.5 - 2.4 cm as well as 1.5 - 2.4 and 3.6 - 4.5 cm by weight were observed to occur  through the Shannon-Wiener test. The species by-catch has displayed heterogeneity characteristics.
