Características produtivas de Kinosternon scorpioides nas fases de acasalamento, postura e eclosão, criados em cativeiro na Amazônia

The aim of this article was to study the indexes of mucua (Kinosternon scorpioides) productive characteristics during copulation, egg laying and hatching, in order to provide an adequate management for the sustainability of the activity. 84 couplings, 742 egg laying and 1,979 births in captivity were analyzed, from which we determined the reproductive season and distribution of couplings; coupling duration; the sexual reason; duration of the egg development period (EDP), frequency of multiple egg laying; duration of nesting period; correlation between nesting time and the number of eggs; the number of viable eggs; the correlation between egg number, weight, length and the descriptive analysis for biometric characteristics and egg weight; duration of the incubation period; the season for births; descriptive analyses of hatchling weight, body measurements and the correlation between variables. The reproductive period is seasonal, concentrating couplings during the rainy season, and the average coupling duration was 00:23:00 h, with sexual reason of 2.38 ± 1.67:1. The EPD was 122.98 ± 45.38 days. Nesting distribution showed a climax tendency between the of June and August. The nesting average was 02:57:00h. The egg viability was 20%. The correlation between biometric characteristics, weight, and the number of eggs laid were positive. The egg biometric results were 34.5 mm long and 18 mm wide, with weight of 7.90 g. The incubation period was 129.31 ± 19.57 days, with births concentrating between the months of September and December. All correlations of biometric characteristics with hatching weight were positive.
