“…Nessa cidade foram implementados projetos pilotos de cultivo de vieiras Nodipecten nodosus, mexilhões Perna perna e ostras japonesas Crassostrea gigas (SODRÉ;REZENDE, 2008). O cultivo de moluscos bivalves nesse município ocorre até os dias de hoje, em local abrigado na Ilha dos Cabritos, a 600 m da costa, com profundidade média de 4 m, salinidade média de 35 ppm (± 2), temperatura média da água de 24°C (± 2) e localidade próxima ao estuário (SOUZA et al, 2019). O fortalecimento da atividade de maricultura no município ocorreu em 2014, ano que foi fundada a Associação dos Maricultores de Piúma (AMPI), atualmente composta por 12 famílias.…”

RESUMO Este estudo objetivou verificar a qualidade microbiológica da água e dos mexilhões cultivados pela Associação dos Maricultores de Piúma (AMPI), Espírito Santo, Brasil. Foram realizadas sete coletas de água e mexilhões, mensalmente, entre outubro de 2016 e maio de 2017. Os mexilhões foram coletados nos long lines da AMPI, e em cada mês foram coletados 40 mexilhões Perna perna e 100 mL de água do local. O material coletado foi destinado ao laboratório para a realização das análises microbiológicas em duplicata, número mais provável de coliformes totais (CT) e termotolerantes (Ctt), presença ou ausência de Salmonella sp e número de unidades formadoras de colônias de Staphylococcus aureus. Os resultados mostraram que o número de Ctt nas amostras de água no mês de janeiro estavam acima do permitido pela Resolução n° 357 do Conselho Nacional do Meio Ambiente (CONAMA). Já os níveis de Ctt e Staphylococcus aureus na carne dos mexilhões mostraram-se dentro do limite aceitável pela RDC n° 12 da Agência Nacional de Vigilância Sanitária (ANVISA). Entretanto, foram encontradas bactérias com características do gênero Salmonella sp nos meses de dezembro e março nos mexilhões, impossibilitando sua comercialização e seu consumo. Durante esses meses, a cidade tem alto fluxo de turistas. Por fim, recomenda-se a realização das análises microbiológicas continuamente, principalmente no período do verão, época que tem grande fluxo de turistas no município de Piúma e que registrou presença de Salmonella na carne dos mexilhões e níveis de Ctt na água acima do permitido pelas legislações vigentes.

The removal of shellfish (Perna perna) from de rocky shores for human consumption is a traditional activity in Santa Catarina Island (ISC), Florianopolis, Brazil, constituting a provisioning ecosystem service. This activity is originally linked to fishing and subsistence; however, it acquired commercial purpose after the 1980’s. After the 1990’s, shellfish started to be exploited as seeds for mariculture, increasing pressure on natural stocks. It is fundamental to know the aspects of the extraction of shellfish to manage this resource. This work sought to fill in the gaps in the knowledge on the extraction, the main points being the identity of the actors involved, the location of extraction sites and the legislation relating to the activity. As to describe the characteristics of this activity, a set of interviews took place with key members of the neighboring communities, experts in related fields, and with beach goers in eight locations in ISC. The legislation found covers several of the points required for the management of the activity; however, no indication of supervision by the competent bodies was found, nor the required licenses were issued. The stocks are located on the rocky stretches of the East side of the island and on the more exposed parts of the North shore. The purpose of the mussels affected the capture method: mussels intended for commercialization was extracted by diving while mussels for own consumption were extracted from subaerial shores. All the extractors located were male and lived in Florianopolis, who favor summer months and extract only occasionally. The extractors believe that the amount of available P. perna has decreased, but the change of the source of mariculture seeds from rocky shores to artificial collectors decreased the pressure on said shores, but their rotation methods used are rudimentary. Failures in management, in rotation, in the issuing licenses, lack of supervision, and pollution are the main threats in maintaining the provision of service represented by mussels. This research subsidizes the decision making and serves as bases for other studies on provisioning services of the natural rocky coasts. Keywords: Mussels, Coastal Management, Provisioning services.

Near infrared spectroscopy: a method for the monitoring and management of the commercial exploitation of the brown mussel (Perna perna) in southeastern Brazil

et al. 2023

Perna perna (Linnaeus, 1758) is one of the most commercialized mollusk species in Brazil. The individuals with a shell length of at least 50 mm are considered to be adults and suitable for commercialization and human consumption. However, the lack of control over the size of extracted mussels is a recurrent and worrisome issue, which may compromise the long-term survival of natural stocks. The present study evaluated the potential to differentiate juvenile brown mussels from adult individuals by using Near Infrared Spectroscopy (NIRS). A total of 176 mussels were obtained from Jurujuba and Vermelha beaches, both located in Guanabara Bay, in the state of Rio de Janeiro, Brazil. Spectra were obtained from the muscle group and a specific part of the shell, with the specimens being separated by size (shell length < 50 mm or > 50 mm), following the current Brazilian legislation. The classification of the muscles by mussel size obtained a hit rate of 66.03%, while the hit rate of the shells was 78%. The two groups were also distinguished efficiently when the two localities were analyzed separately. The results reflect the influence of environmental factors on the chemical composition of the P. perna adults from different areas, with a 85.71% hit rate. The results indicate that NIRS is a potentially effective diagnostic tool for the monitoring and management of the commercial exploitation of natural P. perna stocks.
