Influence of salinity on the physiological conditions in mussels, Perna perna and Perna viridis (Bivalvia: Mytilidae).
Perna genus was introduced to Venezuela, but nowadays, Perna perna and Perna viridis coexist and are commercially exploited from their natural beds. The aim of this work was to determine the effect of salinity on the physiological conditions of these species by studying RNA/DNA and Protein/DNA ratios. The organisms were collected from natural beds at La Esmeralda, Sucre State, Venezuela, and ac...
متن کاملEffect of zinc and benzene on respiration and excretion of mussel larvae (Perna perna) (Linnaeus, 1758) (Mollusca; Bivalvia).
The presence of pollutants in the ocean may affect different physiological parameters of animals. Oxygen consumption and ammonia excretion were evaluated in D-shaped larvae of mussels (Perna perna) exposed to zinc sulphate (ZnSO(4)) and benzene (C(6)H(6)). When compared to the control group, both pollutants presented a significant reduction in oxygen consumption. A reduction in the ammonia excr...
متن کاملTemporal genetic differentiation in cultured and natural beds of the brown mussel Perna perna (Mytilidae).
Perna perna is the most important cultivated mussel of Santa Catarina, Brazil, sustaining an important economic input for many local families. Natural stocks of P. perna are depleted by the extraction of adults and seeds for consumption and culture. The aim of the present study was to use the microsatellite locus pms-2 to study the variation of the genetic composition and diversity between natu...
متن کاملMucus Secretion Responses to Various Sublethal Copper (II) Concentrations in the Mussel Perna perna
The purpose of this study was to evaluate the use of mucus production as a biomarker. This was done by exposing the mussel Perna perna to various sublethal concentrations of Cu. Mussels are effective as a bioindicator species as they accumulate Cu in their tissues. Differences in mucus production rates were evaluated at different Cu concentrations. The findings of this study indicate that incre...
متن کاملPopulation dynamics of the nonindigenous brown mussel Perna perna in the Gulf of Mexico compared to other world-wide populations
Texas Gulf of Mexico populations of the marine mytilid Perna perna (Linnaeus, 1758) were sampled monthly on Fish Pass Jetty (FP) (27°41’ N) from September 1993 to February 1995 and Mansfield Pass Jetty (MP) (26°34’ N) from March 1994 to June 1995 within 1 yr of initial colonization. Population density and mussel size distributions allowed identification of annual cohorts. Mean individual tissue...
