Genotoxic and mutagenic effects of chlorothalonil on the estuarine fish Micropogonias furnieri (Desmarest, 1823)

Environmental Science and Pollution Research, 2021
Chlorothalonil is a fungicide widely used in agriculture as well as an active ingredient in antifouling paints. Although it causes toxic effects on non-target organisms and can accumulate in fish tissues, little is known about its sublethal effects.

Pectoral fins of Micropogonias furnieri: a histochemical and ultrastructural study

Fish Physiology and Biochemistry, 2008
The myotomal fibres of the pectoral fins of white croaker (Micropogonias furnieri) have been studied using histochemical techniques and transmission electron microscopy (TEM). Succinic dehydrogenase (SDH) for mitochondria, periodic acid Schiff (PAS) for glycogen, Sudan Black for lipids and myosin-adenosintriphosphatase (mATPase) pre-incubated at ...

Mucous Cells in Micropogonias furnieri gills: Histochemistry and Ultrastructure

Anatomia, Histologia, Embryologia, 2001
The characteristics of the mucous cells located in the gills of the fish Micropogonias furnieri were investigated. Using histochemical procedures that included methods for localization and characterization of glycoproteins (GPs), no differences were detected between the mucous cell contents ...

Ultrastructure and Histochemical Study of Glycoconjugates in the Gills of the White Croaker (Micropogonias furnieri)

Anatomia, Histologia, Embryologia, 2005
SummaryThe ultrastructure of the primary and secondary lamellae of gills was investigated in a marine teleost, the white croaker. The following cells were identified and briefly described: pavement cells, mucous cells, mitochondria‐rich cells and rodlet cells. These cell types are present throughout the length of the lamellae. They are studied by means

The Mucosa of the Digestive Tract in Micropogonias furnieri: A Light and Electron Microscope Approach

Anatomia, Histologia, Embryologia, 2008
SummaryThe histomorphological aspects as well as the histochemical content and distribution of glycoproteins (GPs) in the mucosa of the digestive tract of the white croaker Micropogonias furnieri were studied. The buccopharyngeal cavity and the esophagous showed a squamous stratified epithelium with mucous cells.

Population structure and ontogenetic habitat use of Micropogonias furnieri in the Southwestern Atlantic Ocean inferred by otolith chemistry

Fisheries Research, 2021
Abstract The whitemouth croaker Micropogonias furnieri is a demersal sciaenid fish widely distributed in Atlantic coasts and estuaries from Mexico to Argentina. In the South Atlantic (33°- 41 °S), there are two stocks: Rio de la Plata (RDP) and El Rincon (ER), respectively.

Metazoan parasites as biological tags for stock discrimination of whitemouth croaker Micropogonias furnieri

Journal of Fish Biology, 2010
Examination of 248 adult specimens of whitemouth croaker Micropogonias furnieri from five localities along the Brazilian coast revealed 8735 parasites belonging to 41 metazoan species. Samples from Ceará to Bahia and Rio de Janeiro to Santa Catarina showed a high level of correct assignation (92 and 87%, respectively) and cross assignation (i.e. almost

Gonadotropin-releasing hormone in two perciform fishes: Micropogonias furnieri and Pagrus pagrus

Fish Physiology and Biochemistry, 2001
Gonadotropin-releasing hormone (GnRH) molecular variants were characterized by gradient reverse phase high performance liquid chromatography (RP)-HPLC) from brain extracts of two perciforms with economic importance for Argentina and Uruguay. RP-HPLC fractions were tested in radioimmunoassays (RIAs) with both poly-specific and specific antisera.

Effect of direct electric current on microbiological quality of white croaker (Micropogonias furnieri)

Food Microbiology, 2005
White croaker (Micropogonias furnieri) were submitted to a direct electric current post-mortem and stored refrigerated at 4°C for 16 days. Flesh and surface of electrically treated fish exhibited higher mesophilic bacteria counts than controls on the 3rd and on the 6th day of storage, respectively.
