Asian Yellow Pond Turtle(Mauremys mutica) is native in tropical East Asia,and is a member of the family Bataguridae.Asian Yellow Pond Turtle had been one of the most popular aquaculture species in Asian owing to the high values for view and Traditional Chinese Medicine.The egg-laying behavior of yellow pond turtle has been observed in the condition of artificial environment in this paper. It indicated that the sum of average temperature of per month from February to April was positive correlative with the quantity of eggs laying in April(P<0.05) by analyzing the data of temperature and egg-laying of turtle in statistics from 2001 to 2006.The time egg-laying begins of the turtle population was controlled in those years by the sum of average temperature of per month from February to April.It was detected that the turtle liked to lay eggs in a high mound,36.378±7.140 cm(n=30) above egg-laying site plane.According to the inherent egg-laying behavior of yellow pond turtle,the whole nesting process was divided into six stages: stage Ⅰ meaning selecting nest,stage Ⅱ meaning excavating body pit,stage Ⅲ meaning excavating egg chamber,stage Ⅳ meaning laying egg,stage Ⅴ meaning covering nest,and stage Ⅵ meaning re-entry water.Time taken by turtle for nesting in six stages was analyzed.The result showed that there was no significant relationship between the time taken in stages Ⅰ, Ⅱ,Ⅲ,Ⅴ,Ⅵ and the clutch.But the relationship between stage Ⅳ and clutch size was significant.
