Molecular and biochemical effects of the antifouling DCOIT in the mussel Perna perna

Comparative Biochemistry and Physiology Part C: Toxicology & Pharmacology, 2021
Biological fouling is an unwanted phenomenon that results in economic losses to the shipping industry. To prevent fouling, antifouling paints are used. DCOIT (4,5- dichloro-2-n-octyl-4-isothiazolin-3-one) is a biocide present in many antifouling paint formulations, and is toxic to a wide range of organisms.

Elemental Concentrations in the Shells of the Mussel Perna perna: Discrimination of Origin

Biological Trace Element Research, 2023
The potential use of elemental concentrations and element:calcium (Ca) ratios as indicators of provenance for bivalve mollusks on the Brazilian coast is evaluated herein for the first time. The approach was applied to shells of the mussel Perna perna (target of extractive fisheries) from geographically close areas but under distinct environmental and ...

Morphological characterization of hemocytes of the brown mussel Perna perna: An update

Fish & Shellfish Immunology, 2022
Considering the importance of hemocyte characterization for immunological studies, this work aimed to characterize the hemocyte types of Perna perna mussels combining transmission electron microscopy and flow cytometry with the classical optical microscopy.

Pigment alterations in the brown mussel Perna perna

Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 2008
Potential sex and/or gametogenic stage differences in the metabolism of chlorophyll-a and carotenoids in the brown mussel Perna perna of southern Brazil were studied using high performance liquid chromatography (HPLC). Carotenoids derived directly from diet (phytoplankton) were fucoxanthin plus diatoxanthin (diatoms), alloxanthin (cryptophytes) and ...

First evidence of transcriptional modulation by chlorothalonil in mussels Perna perna

Chemosphere, 2020
Gills are considered a key player in organism defenses against environmental pollutants. Since it is the major site of uptake of waterborne chemicals, the modulation of important cellular defenses is expected in this tissue. Chlorothalonil, a fungicide presented in herbicides and antifouling paints, might be responsible for toxicity in marine biota. In

Vacuum Cooling of Cooked Mussels (Perna perna)

Food Science and Technology International, 2006
Mussels pass through a thermal treatment during industrial processing with hot water or steam and then are pre-cooled before the manual extraction of the meat. This pre-cooling is classically accomplished by the immersion of the cooked mussels in cold water.

210Po concentration in Perna perna mussels: looking for radiation effects

Journal of Environmental Radioactivity, 2008
Twenty ropes with 400 Perna perna mussels seeds (3 cm shell size) were set-up on floating structures at Cabo Frio Island, Arraial do Cabo, approximately 100 km northeast of Rio de Janeiro city. A rope was taken out on a monthly basis, and the shell sizes of 100 seeds were measured.

Biochemical responses in mussels Perna perna exposed to diesel B5

Chemosphere, 2015
In Brazil B5 blend (5% biodiesel and 95% diesel oil) has been adopted as mandatory fuel since 2010 for automotive vehicles. Since little is known about the effects of B5 exposure can promote on antioxidant system of marine biota this study aimed to assess if B5 can generate modifications in antioxidant parameters of mussels Perna perna. To address this

The ionic basis of cardiac activity in the bivalve mollusc Perna perna

Journal of Experimental Marine Biology and Ecology, 2000
The ionic basis of cardiac activity and aspects of excitation-contraction (E-C) coupling were investigated in the isolated heart of the bivalve mollusc Perna perna, using the sucrose-gap technique. The role of the principal ions was established employing artificial seawater, in which specific ion concentrations were modified, and ion channel blockers ...

Response of Fouling Brown Mussel, Perna perna (L.), to Chlorine

Archives of Environmental Contamination and Toxicology, 2003
Perna perna (L.), the edible brown mussel, is very widely distributed in the tropical and subtropical regions and is commonly found in rocky shores. Apart from being a candidate for commercial cultivation, P. perna is also a common pest organism in cooling water systems of coastal power stations.
