Evidence of Alternative Splicing as a Regulatory Mechanism for Kissr2 in Pejerrey Fish. [PDF]
Front Endocrinol (Lausanne), 2018 Kisspeptin receptors are G-Protein-Coupled Receptors that regulate GnRH synthesis and release in vertebrates. Here, we report the gene structure of two kisspeptin receptors (kissr2 and kissr3) in pejerrey fish. Genomic analysis exposed a gene structure with 5 exons and 4 introns for kissr2 and 6 exons and 5 introns for kissr3.

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 ...

Occurrence and control of Chilodonella spp. in pejerrey Odontesthes bonariensis [PDF]
Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2011 O presente trabalho teve por objetivo relatar a ocorrência e controle de infecção parasitária por Chilodonella spp. em alevinos de peixe-rei (O. bonariensis). A Chilodonella spp. é um ciliado que parasita tegumento e brânquias de peixes, podendo ocasionar grande mortalidade.

Main diseases of pejerrey (Odontesthes bonariensis) in central Argentina [PDF]
Pesquisa Veterinária Brasileira, 2006 Argentina's central region includes an important area covered by shallow pampean lakes and dams. In these environments, fishing of pejerrey Odontesthes bonariensis Valenciennes, 1835 (Pisces, Atherinopsidae), the most important fresh-water fish of the country, is a relevant social activity and also a considerable economic resource.
