Post-mortem Fertilizing Capacity of Spermatozoid Chirostoma jordani (Atheriniformes: Atherinopsidae)

Genetics of Aquatic Organisms, 2023
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,

Sex determination in fish: Odontesthes spp. (Atherinopsidae) as experimental models [PDF]

, 2015
The sex of the offspring is the result of a unique process leading, in a binary fate, to the development of male or female characteristics. In this context, the aim of the present work is to present atherinopsid fish as excellent models to study sex ...

Otolith and vertebral morphology of marine atherinid species (Atheriniformes, Atherinopsidae) coexisting in the southwestern Atlantic Ocean

Ciencias Marinas, 2010
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

Oocyte structure and ultrastructure in the Mexican silverside fish Chirostoma humboldtianum (Atheriniforme: Atherinopsidae)

Revista de Biología Tropical, 2007
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

Intraspecific karyotypic variation in the silverside fish Chirostoma humboldtianum (Atheriniformes: Atherinopsidae)

Hidrobiológica, 2016
Within its genus, Chirostoma humboldtianum is one of the species with the widest distribution, inhabiting lake and pond environments along the Lerma-Santiago basin in the Mexican Plateau. Although the species is of great ichthyological, economic, and cultural relevance, factors related to human activity such as habitat loss, pollution, overfishing, and
