Dietary exposure to polycyclic aromatic hydrocarbons (PAHs) may pose serious threats to human health. However, within the Caribbean, quantitative assessments regarding the risks associated with dietary PAH exposure remain sparse. This study investigated PAH presence in edible biota from the Caroni Swamp and quantitatively assessed the potential health ...

Analysis of the inflammatory reaction induced by the catfish (Cathorops spixii) venoms
Toxicon, 2007Cathorops spixii is one of the most abundant venomous fish of the southeastern coast of the State of São Paulo, and consequently causes a great part of the accidents seen there. The accidents affect mainly fishermen, swimmers and tourists and are characterized by punctiform or wide wounds, erythema, edema, pain, sudoresis, indisposition, fever, nausea,

Biologia reprodutiva dos bagres marinhos Genidens genidens (Valenciennes) e Cathorops spixii (Agassiz) (Siluriformes, Ariidae), na Baía de Sepetiba, Rio de Janeiro, Brasil [PDF]
Revista Brasileira De Zoologia, 1999 The reproductive cycle of the marine catfishes Genidens genidens Valenciennes, 1833 and Cathorops spixii Agassiz, 1839 in the Sepetiba Bay, was assessed by an annual period of sampling from October 1993 to September 1994. The fishes were caught by standardized otter trawl and environmental parameters of temperature, salinity and transparency of water ...

Cathorops spixii (Pisces) gill study through Scanning Electron Microscopy
Proceedings, annual meeting, Electron Microscopy Society of America, 1990The scanning electron microscope is very useful for the detail three-dimensional external understanding of structures, such as fish gills, that present varied aspects according to systematic position or to adaptations to the environment. Cathorops spixii lives near to muddy bottom, in brackish water, and was collected from the Paranaguá bay in the ...
