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

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.

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 ...

Elemental Contamination in Brown Mussels (Perna perna) Marketed in Southeastern Brazil

Biological Trace Element Research, 2021
Perna perna mussels, abundant throughout the Brazilian coast, are routinely applied as bioindicators in environmental monitoring actions due to their sessile and filter-feeding characteristics. In addition, they are noteworthy for their food importance, especially for coastal populations.

Physioecology of the mussel Perna perna (Mytilidae) in Southern Brazil

Aquaculture, 2007
Abstract The energy budget or scope for growth in bivalves has been applied to economically important species, in studies on the limits of climactic adjustment for a particular ecological niche. This paper presents the physiological rates of respiration, clearance and absorption efficiency of the marine mussel Perna perna , determined during the ...

Invasive species fouling Perna perna (Bivalvia: Mytilidae) mussel farms

Marine Pollution Bulletin, 2022
Invasive, fouling species increase management costs and reduce mussel growth, which jeopardizes mariculture. We studied the distribution of eight invasive species in Santa Catarina, the leading mussel producer in Brazil. Our goals were to determine their spatial distribution and prevalence on farm structures (buoys, long lines, and mussel socks), as ...

A novel cathepsin from the mussel (Perna perna) (Linne)

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1988
Abstract 1. 1. Proteases from the digestive gland of the mussel Perna perna were subjected to an isolation procedure similar to that used for mammalian thiol cathepsins. 2. 2. A protease was purified by ammonium sulphate fractionation, molecular exclusion chromatography and ion exchange chromatography on CM-Sephadex. 3. 3.

Some haemato-immunological parameters in the mussel Perna perna

Fish & Shellfish Immunology, 1999
The aim of this study was to establish the normal pattern of some haemato-immunological parameters in the mussel Perna perna to serve as a reference for further studies using this species as a biological indicator of environmental contaminants. We investigated the morphology and cytochemistry of the circulating haemocytes of P.

DNA damage in digestive gland and mantle tissue of the mussel Perna perna

Comparative Biochemistry and Physiology Part C: Toxicology & Pharmacology, 2003
Data concerning the susceptibility of DNA to damage by reactive oxygen and nitrogen species and other endogenous compounds produced by physiological stress in marine organisms is lacking, especially in bivalve mollusks. In this article, we analyzed the background levels of lipid peroxidation (malondialdehyde, MDA), 8-oxo-7,8-dihydro-2'-deoxyguanosine ...
