Glycoproteins histochemistry of the gills of Odontesthes bonariensis (Teleostei, Atherinopsidae)
The histochemistry of glycoproteins (GP) in the mucous cells of the gills of the silverside Odontesthes bonariensis was identified with: (1) oxidizable vicinal diols; (2) sialic acid and some of their chain variants, carbon 7 (7C), carbon 8 (8C) or carbon 9 (9C); (3) sialic acid residues without O‐acyl substitution and with O‐acyl substitution at 7C ...

Evidence of a landlocked reproducing population of the marine pejerrey
AbstractIn South America, the order Atheriniformes includes the monophyletic genusOdontestheswith 20 species that inhabit freshwater, estuarine and coastal environments. PejerreyOdontesthes argentinensisis widely distributed in coastal and estuarine areas of the Atlantic Ocean and is known to foray into estuaries of river systems, particularly in ...

Consequences of temperature and temperature variability on swimming activity, group structure, and predation of endangered delta smelt [PDF]
The effects of water temperature on individual and group movement behaviour in prey fish can affect ecological interactions such as competition and predation, but how variability in temperature influence fish behaviour is less understood.

Post-mortem Fertilizing Capacity of Spermatozoid Chirostoma jordani (Atheriniformes: Atherinopsidae)
Post-mortem fertilization is considered a technique in which semen is extracted from a dead male to fertilize the egg of a living female. Therefore, this technique can be an excellent option in the face of the loss of biodiversity of multiple animal species. The objective of this research is to implement post-mortem assisted reproduction in the charal,

Studies on marine ecosystems rely on the identification of fish prey species of piscivores (fish, aquatic mammals, and aquatic birds) based on their bones and otoliths. The stomach contents of piscivores show predation on marine atherinids of commercial

The structural and ultrastructural features of gonads from endemic Mexican fish have received scarce attention. This study describes the histological and ultrastructural characteristics of the oocyte in Chirostoma humboldtianum. The ovary is asynchronic, and as such, most phases of oocyte development are found in the same ovary. The complete process of
