description ABSTRACT: In this study we describe the early stages of development of Bryconamericus caucanus under laboratory conditions. Mature females (mean weight 8.12 g) received two intraperitoneal doses of Carp Pituitary Extract (1st dose of 0.5 mg / kg at time 0 and 2nd dose of 5 mg / kg 12 h later), and mature males received a single dose of 0.5 mg / kg at the time of the 2nd dose to the females. Extrusion of eggs was performed at 152.25 Accumulated Thermal Units. Eggs of B. caucanus were yellow, round shaped, non-adhesive, and the perivitelline space after hydratation was moderate. Hatching occurred 28 h 20 min after fertilization (21oC, 594.3 Accumulated Thermal Units). The morphological features of the egg and early embryo of B. caucanus were similar to previous reports in other members of the Tetragonopterinae, but the embryonic development was particularly long in this species

Hembras maduras (peso promedio de 8,12g) recibieron dos dosis intraperitoneales de extracto de hipófisis de carpa (1a dosis de 0,5 mg/Kg en la hora cero y 2a dosis de 5 mg/Kg en la hora 12). Asímismo, los machos maduros recibieron una única dosis de 0.5 mg / kg en la 2a dosis de las hembras. Se llevó a cabo desove en seco a 152,25 grados-hora luego de la aplicación de la 2a dosis hormonal. Los huevos de B. caucanus eran amarillos, redondeados, no adhesivos y el espacio perivitelino luego de la hidratación fue moderado. La eclosión se registró 28 h 20 min después de la fertilización (594,3 grado-horas a 21oC). La respuesta positiva a la hipofización y las características morfológicas del huevo y del embrión de B. caucanus fueron similares a los reportes previos en otros miembros de la subfamilia Tetragonopterinae, siendo el desarrollo embrionario de B. caucanus particularmente prolongado.COL00665614application/pdfengSociedad Chilena de AnatomíaTemuco, Chilehttp://creativecommons.org/licenses/by-nc/2.5/co/https://creativecommons.org/licenses/by-nc/4.0/info:eu-repo/semantics/openAccesshttp://purl.org/coar/access_right/c_abf2Embryonic Development of Bryconamericus caucanus (Characidae: Tetragonpterinae) under Laboratory ConditionsDesarrollo embrionario de Bryconamericus caucanus (Characidae: Tetragonpterinae) en condiciones de laboratorioArtículo de investigaciónhttp://purl.org/coar/resource_type/c_2df8fbb1https://purl.org/redcol/resource_type/ARThttp://purl.org/coar/version/c_970fb48d4fbd8a85info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionSelección ArtificialSelective BreedingCharaciformesPecesFisheshttp://aims.fao.org/aos/agrovoc/c_39781http://aims.fao.org/aos/agrovoc/c_2943Int.
