Between October and November 2020, substantial progress was made in direction of achiveing the ob- jectives of the amphibian captive breeding at ASA associate Mitsinjo analysis heart. In whole, there are at the moment greater than 150 terraria occupied with 11 widespread species and 1 Critically Endangered species. All frog species are lively and are in breeding season. Even in captivity, all captive bred have tailored to this season.

Over the previous two months, we now have additionally produced a brand new era of the Golden Mantella Frog (Mantella aurantiaca). By the top of Novem- ber, we now have saved 45 egg clutches, with 300 tadpoles already within the water. These shall be reintroduced into the wild between March and April, 2021.

Species monitored in captivity 90% of these people beforehand caught within the wild are outdated and wish

to be modified within the subsequent few years to forestall mortality. Although some species bred with decrease fertil- ity charges throughout this breeding sea- son, all of the captive species are once more chosen for husbandry through the use of/ enhancing new technics. They’re primarily based on the tree Frog, the highest hill species and, after all, the Golden Mantella Frog, which have been ready for the subsequent launch. With regard to the subsequent generations, we now have discovered some clutches from F2, however these aren’t fertile. When this occurs, Mitsinjo’s technician discover a method to enhance this F2 husbandry to supply F3 for the assorted frog species stored within the heart.

The success of captive breeding relies on with the ability to present the requirements for the species. Reside meals cultures, comparable to insect manufacturing, play essential roles for these amphibian species. We expanded the manufacturing of our residing meals cultures each week. We’d additionally like to enhance different residing meals husbandry cultures comparable to termites, isopod and different insect (larvae), since these could be the very best meals sources for some frog species, as talked about in our earlier article within the Frogress Report.

Issues and issues

Monetary assets are a few of the best wants to enhance our actions and personnel who’re accountable for the captive breeding program. Since 2011 till now, we now have not obtained recommendation, technical sup- port or subject coaching from the ASG Madagascar. Furthermore, it has additionally turn out to be troublesome to obtain permits from the Malagasy authorities.


We are going to current these issues to all stakeholders, for the soundness of the captive breeding program in Madagascar, which is the primary of its sort.
