Growth and histopathological effects of chronic exposition of marine pejerrey Odontesthes argentinensis larvae to petroleum water-soluble fraction (WSF). [PDF]

Ambio, 2012
The water-soluble fraction (WSF) of petroleum contains a mixture of polycyclic aromatic hydrocarbons, volatile hydrocarbons, phenols, and heterocyclic compounds, considered deleterious to aquatic biota. Marine "pejerrey" Odontesthes argentinensis (Teleostei: Atherinopsidae) has a great commercial importance in local fisheries and a high potential for ...

Presence of trace elements in the silverside Odontesthes argentinensis

Marine Pollution Bulletin, 2017
The silverside Odontesthes argentinensis is an economically significant resource for commercial fisheries in South America. We evaluated the presence of trace elements in the stomach content and fish tissues (muscle and otoliths) of O. argentinensis. In addition, we assessed the presence of trace elements in its prey (zooplankton) and in seawater in a ...

Biological traits and growth patterns of pejerreyOdontesthes argentinensis

Journal of Fish Biology, 2012
This study assesses for the first time the relationship between annual cycles of different biological indices with growth patterns of a marine pejerreyOdontesthes argentinensispopulation near its southern‐distribution boundary in North Patagonia. The reproductive period is between September and November evidenced by an increase in the gonado‐somatic ...

Alterations in the Gill Filaments and Secondary Lamellae of Cirrhinus mrigala Exposed to “Nuvan,” an Organophosphorus Insecticide

Journal of Histology, Volume 2014, Issue 1, 2014., 2014
The alterations in the epithelium of the gill filaments and the secondary lamellae of the gills of Cirrhinus mrigala, on exposure to “Nuvan,” have been explored in the present investigation using light and scanning electron microscopy. The fishes were exposed to two sublethal concentrations, 5 mg/L and 15 mg/L, of “Nuvan.” The changes are more rapid ...
