Modern reproductive technologies for amphibian biodiversity preservation

Abstract

Breeding of amphibians in captive is one of the modern strategies for biodiversity preservation of batrochofauna. In our article we present the reproductive technologies to obtain the offspring from different amphibian threatened species, which live in zoos, nurseries and in collections of nonprofessionals. In this article we discuss two basic approaches in current reproductive technologies — the employment of gonadotropic hormones and artificial fertilization. Gonadotropic hormons could be used for stimulation of amphibian spawning to obtain already fertilized eggs, as well as for sampling of nonfertilized eggs and sperm that can be further used in artificial fertilization. We discuss the approaches to artificial fertilization both immediately after obtaining eggs and sperm, and in several days (delayed artificial fertilization) or months (adjourned artificial fertilization after cryopreservation).
