Reproducción en cautiverio de vizcaína Curimata mivartii con extracto pituitario de carpa

Abstract: Con el objetivo de reproducir vizcaína Curimata mivartii, ejemplares de dos años de edad (n= 54), mantenidos en estanques en tierra (0,1 pez/m2) fueron inducidos con extracto pituitario de carpa (EPC) (Argent, USA) a razón de 6 mg/Kg de peso para las hembras en dos aplicaciones (10 % y 90% con 12 horas entre aplicación); mientras que los machos fueron inducidos con 4,8 mg/Kg EPC en dosis única. Antes de la inducción hormonal a cada hembra le fue realizada biopsia para verificar su estado de maduración gonadal.… Show more

“…This distance was estimated based on the post-fertilization incubation time of the embryos and larvae collected, keeping in mind the average speed of the river at the time of sampling, which was calculated using a flowmeter (General Oceanics, 2030R). The incubation time for each period and development phase for migratory species was obtained from information available in the literature [35][36][37][38].…”

“…Thus, the presence of embryos and vitelline larvae suggests proximity to a spawning site [47]. When considering that the embryos of potamodromous fish generally hatch 14-20 hours post-fertilization (depending on the water temperature), this suggests that when embryos are being collected, the spawning site is approximately 20 hours away [35][36][37][38] depending on the species, developmental stage, and water speed upstream from the sampling site.…”
