Usefulness of heterologous microsatellites obtained from Genypterus blacodes (Schneider 1801) in species Genypterus off the Southeast Pacifc

Population structure and demographic history of Genypterus blacodes using microsatellite loci

“…These loci, used on organisms from Australian waters, did not refute the one-stock hypothesis . Off the Chilean coast, there has only been one study on a Genypterus species using microsatellite loci (Canales-Aguirre et al, 2010). Further, no population genetics studies have been performed to date for G. blacodes, even though it is an economically important species with a wide geographic distribution.…”

Genetic variability in jack mackerel Trachurus murphyi Nichols: New SSRs loci and application

“…Heterologous markers are useful when no species-specifi c markers are available (e.g. Canales-Aguirre et al 2010b). Notwithstanding the usefulness of specifi c microsatellite loci for T. murphyi, those at the population level (as described in CanalesAguirre et al 2010a) could provide more information on the genetic diversity of the species.…”

Nuclear DNA content in the red conger eel Genypterus chilensis (Guichenot, 1881) (Actinopterygii: Ophidiidae)

“…Genypterus chilensis (Guichenot 1881) is an abundant fi sh species distributed along the coasts of the Southeastern Pacifi c Ocean. In Chile the species is distributed from Arica (18ºS) to Archipiélago de los Chonos (47ºS), with a bathymetric distribution between 20 and 150 m. At present, the available biological studies on G. chilensis include parasitism, population dynamics, and temporal variation of the diet, reproductive cycle, and DNA-microsatellite characterization (Vergara & George-Nascimento 1982;Paz 1991;George-Nascimento et al 2004;Chong et al 2006;Chong & González 2009;Canales-Aguirre et al 2010). However, cytogenetic data on G. chilensis are not available and basic aspects such as nuclear DNA content remain unknown.…”
