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

Abstract: Objetivou-se estudar os índices das características produtivas de muçuãs (Kinosternon scorpioides) visando nortear manejos adequados para a sustentabilidade da atividade. Analisou-se 84 acasalamentos, 742 posturas e 1979 nascimentos em cativeiro, determinando-se: a estação reprodutiva e a distribuição dos acasalamentos; a duração do acasalamento; a razão sexual; a duração do período de desenvolvimento do ovo (PDO); a frequência de múltiplas posturas; duração do período de nidificação; a correlação entre tempo … Show more

“…K. scorpioides features diapause and embryonic aestivation (Ewert, 1985, 1991), which directly affects incubation time (Ewert, 1985; Ewert & Wilson, 1996; Rafferty & Reina, 2012). Here it is shown that the incubation period occurs at 129.50 ± 21.73 days (Braga, 2019), similar to several studies carried out in northern Brazil (Costa et al, 2017; Guimarães, Silva, & Palha, 2017). The long Stage 26 (prehatch), observed during 60 days of incubation, demonstrates the presence of embryonic aestivation (Braga, 2019).…”

“…In the Amazon biome, chelonian meat is consumed for subsistence purposes [33]. The most consumed species are the Amazonian turtle, Arrau River Turtle, (Podocnemis expansa), the Tracajá, Yellow-spotted Amazon River Turtle, (Podocnemis unifilis), and the Muçuã, Scorpion Mud Turtle, (Kinosternon scorpioides) [34]. Therefore, handling the carcasses of animals with Leptospira can pose a zoonotic threat.…”

“…One of these animals is the scorpion mud turtle (Kinosternon scorpioides), also known as Muçuã or Jurará, a small semiaquatic freshwater turtle found from Costa Rica to northern Argentina and Brazil. Due to their semiaquatic behavior, these animals may play a critical role in the epidemiology of the pathogen [33][34][35].…”
