Uso de la hormona gonadotropina en la inducción a la reproducción del chame <i> dormitator latifrons </i>

Abstract

The present work reveals the studies related by researchers in the reproduction of the chame fish Dormitator latifrons in captivity, with the hormonal induction of gonadotropin, a hormone that is used in several fish for its induction, demonstrated good results and that nowadays follow it using, among the species we have the chame species of our natural environment, several samples of chame were made, where the saline solution, Salmon GnRHa + domperidone was injected obtaining positive results when getting the sperm release of the species, induction made 100% in 24-48 hours, the correct and standardized use of this hormone ensures oocytes and sperm quality in the first larval stages, a species that lives in tropical and subtropical areas, its diet is detritus, organic matter, plant remains and animals, the chame withstands low oxygen conditions, tolerates high temperatures and salin idad, its meat is desired by its nutritional content, in our country Ecuador the marketing of chame meat has a socio-economic support for coastal communities, is captured in the natural environment and transferred for captivity in juveniles, sexual maturity of reproducers begins at 15 cm in length, its female gonadal development is identified by the yellowish coloration proving to be ready for spawning, with the characteristics described there is interest to increase the use of the technique that would improve the population of the species in the water bodies, generating work and food for the population that needs it.
