Resumo: The golden mussel, Limnoperna fortunei (Dunker, 1857), has been found in the estuarine regions of South America, including the Patos Lagoon (Brazil), a huge choked lagoon with an estuarine region that is highly unstable chemically. Limnoperna fortunei space-temporal variability in the lagoon’s estuarine region demonstrated the need to evaluate this species’ ability to survive under salinity shocks. A set of experiments was conducted under controlled laboratory conditions. Specimens were tested under salinities of 2, 4, 6, 8 and 12 ppt, and were exposed for periods of 24, 48, 72, 96 and 240 hours. The mussel can survive (90%) up to a salinity shock of 2 ppt for periods of at least 10 days. Considering the influence of climatic and stochastic events and the chemical instability of the Patos Lagoon estuarine region, it’s unlikely that populations could survive for longer periods (more than a year) in this area.

A variabilidade espaçotemporal de L. fortunei na região estuarina desta laguna evidenciou a necessidade da avaliação da sobrevivência desta espécie sob choques de salinidade. Experimentos foram conduzidos em condições controladas de laboratório. Os exemplares foram submetidos a choques de salinidade de 2, 4, 6, 8 e 12 ppt, por períodos de 24, 48, 72, 96 e 240 horas. O mexilhão pode sobreviver (90%) por períodos de no mínimo 10 dias após um choque de salinidade 2. Considerando a influência de eventos climáticos e estocásticos e a instabilidade química da região estuarina da Laguna dos Patos, é improvável que populações possam sobreviver por períodos maiores (mais de um ano) neste ambiente.2012-03-06T03:29:30Z2012-03-06T03:29:30Z2008info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfANGONESI, Luciana Garcia; ROSA, Natalia Garcez da; BEMVENUTI, Carlos Emílio.
