摘要: Perna perna (Linnaeus, 1758) is the main marine bivalve mussel yielded commercially in Brazil. In spite of this, scientific data very scarce regarding its productivity tropical shallow waters. The Condition Index (CI) used worldwide mariculture to assess animal health, harvest time, and yield. this study, authors CI results from nine different methods season effect on also evaluate potential yield three southern Brazilian bays. were for comparison seasonality mussels reared Sampling was carried out monthly within two 4-month periods, December 2008 August 2009. show a trend seasonal effects results. winter months showed highest lowest values. Between bays, higher values detected animals at Sepetiba Bay, followed by Guanabara Bay Ilha Grande Bay. We suggest that (that considers ratio between soft tissue wet weight total length) should be fishermen, since formula able detect differences sites more easily applied.
