Growing of Larvae of the Caucasian Smooth Newt, Lissotriton lantzi (Wolterstorff, 1914) (Amphibia, Caudata) at Various Temperatures

Abstract

Lantz’s newt, or the Caucasian smooth newt, Lissotriton lantzi, is an endemic species of Caucasian forests. It was included in the Red Data Books of the Russian Federation and Republic of Azerbaijan. The design of a technology for keeping and reproducing this species in captivity will help its conservation. The paper discusses the results of larval growing of Lantz's newt at several temperatures. Newts were obtained from reproduction in artificial conditions. Larvae were grown in double repetition in four temperature regimes, namely: 20.0–24.0°C (21.6°C on average), 23.0–25.5°C (24.7°C), 25.5–29.0°C (27.7°C), and 29.0–32.0°C (31.3°C). The larvae had the highest survival rate at the lowest temperature (100%) and the lowest rate (78% on average) at the highest temperature. The larval development duration before the first young newts came to land was similar at all the temperatures. The average duration of development before metamorphosis was longest at the highest temperature (29.0 –32.0°C). Besides, the newts from this group had the smallest average sizes (total length and weight). The feed costs per metamorph growing were lowest at the water temperatures of 23.5–25.5°C and highest when 29.0–32.0°C. The greatest quantity of feed per weight unit was spent by the newts at the temperatures of 29.0–32.0°C, and the lowest was at the temperature of 23.5–25.5°C. Increasing temperature did not accelerate the larval development. The larvae grown at the highest temperatures had a lowered survival rate, small average sizes and consumed the largest number of feed. The authors recommend growing Lantz's newt larvae in the temperature range of 20–26°C.
