Aquaculture Research, 2006 Brazilian oyster production has expanded considerably over the past decade, increasing from 55 tonnes in 1995 to 2196 tonnes in 2005 (FAO 2005). In addition to the native oyster species, Crassostrea brasiliana (Lamarck 1819) and C. rhizophorae (Guilding 1828), the Paci¢c oyster, C.

Archives of Environmental Contamination and Toxicology, 2020 Urban waste is a complex mixture of different substances, including microplastics and pharmaceuticals and personal care products. Microplastics have a high affinity for hydrophobic substances. One of these substances is triclosan, a bactericide used in a variety of hygiene products. Therefore, microplastics (MPs) may serve as a vector between triclosan

Marine Pollution Bulletin, 2022 This study investigated the sublethal effects of environmentally relevant concentrations of DCOIT on the neotropical oyster Crassostrea brasiliana. Gills and digestive glands of animals exposed to increasing concentrations of DCOIT were analyzed for biochemical, cellular, and histopathological responses.

Chemosphere, 2018 Exposure of aquatic organisms to polycyclic aromatic hydrocarbons (PAH), such as phenanthrene (PHE), may increase the production of reactive oxygen species (ROS) and cause changes in the biotransformation systems. In addition, changes in water temperature can cause adverse effects in the organisms.

Aquatic Toxicology, 2018 Diesel fuel water-accommodated fraction (diesel-WAF) is a complex mixture of organic compounds that may cause harmful effects to marine invertebrates. Expression of microsomal proteins can be changed by oil exposure, causing functional alterations in endoplasmic reticulum (ER).

Revista Brasileira de Gestão Ambiental e Sustentabilidade, 2023 In this study, we report the association between the pea crab Zaops ostreum (Say, 1817) living in the oyster Crassostrea brasiliana (Lamarck, 1819), collected in an estuarine region of Northeast Brazil. Oysters were collected along the mouth of the Santa Cruz Channel, Barra de Catuama (State of Pernambuco), between 2016 and 2017.

Ecotoxicology and Environmental Safety, 2016 The release of untreated sanitary sewage, combined with unplanned urban growth, are major factors contributing to degradation of coastal ecosystems in developing countries, including Brazil. Sanitary sewage is a complex mixture of chemicals that can negatively affect aquatic organisms.

Molecular identification, phylogeny and geographic distribution of Brazilian mangrove oysters (Crassostrea) [PDF]
Genet Mol Biol, 2010 Oysters (Ostreidae) manifest a high degree of phenotypic plasticity, whereby morphology is of limited value for species identification and taxonomy. By using molecular data, the aim was to genetically characterize the species of Crassostrea occurring ...
