      As amphibian populations continue to decline, both government and non-government organisations are establishing captive assurance colonies to secure populations deemed at risk of extinction if left in the wild. For the most part, little is known about the nutritional ecology, reproductive biology or husbandry needs of the animals placed into captive breeding programs. Academic and zoo scientists are beginning to examine different technologies for maintaining the genetic diversity of founder populations brought out of the wild before the animals become extinct from rapidly spreading epizootic diseases. One such technology is genetic resource banking and applied reproductive technologies for species that are difficult to reproduce reliably in captivity.

    • Icon of Hormonal induction of spawning in 4 species of frogs by coinjection with a gonadotropin-releasing hormone agonist and a dopamine antagonist Hormonal induction of spawning in 4 species of frogs by coinjection with a gonadotropin-releasing hormone agonist and a dopamine antagonist (686.1 KB)
      It is well known that many anurans do not reproduce easily in captivity. Some methods are based on administration of mammalian hormones such as human chorionic gonadotropin, which are not effective in many frogs. There is a need for simple, cost-effective alternative techniques to induce spawning. Our approach offers some advantages over other hormonally-based techniques. Both sexes are injected only once and at the same time, reducing handling stress. AMPHIPLEX is a new reproductive management tool for captive breeding in Anura.

    • Icon of Hormonal Induction of Spermiation, Courting Behavior and Spawning in the Southern Bell Frog, Litoria raniformis Hormonal Induction of Spermiation, Courting Behavior and Spawning in the Southern Bell Frog, Litoria raniformis (138.8 KB)
      We trialled the efficacy of various exogenous hormones to induce spermiation, courtship behavior, and spawning in the ‘‘endangered’’ southern bell frog, Litoria raniformis. This and earlier studies indicate that in the efficacy of hormonal induction in amphibians varies between taxa, hormones, and genders.

    • Icon of Reproduction and Larval Rearing of Amphibians Reproduction and Larval Rearing of Amphibians (593.1 KB)
      Reproduction technologies for amphibians are increasingly used for the in vitro treatment of ovulation, spermiation, oocytes, eggs, sperm, and larvae. Recent advances in reproduction technologies for amphibians include improved hormonal induction of oocytes and sperm, storage of sperm and oocytes, artificial fertilization, and high-density rearing of larvae to metamorphosis. In both research and captive breeding programs, it is necessary to provide suitable conditions for the rearing of large numbers of a diverse range of species. Compared with traditional systems, the raising of larvae at high densities has the potential to produce these large numbers of larvae in smaller spaces and to reduce costs.
