Van Binh Ngo, Dac Chung Ngo


Quasipaa verrucospinosa (Bourret, 1937) is an endemic species of Vietnam. A total of 429 specimens (225 males, 173 females, and 31 subadults) were examined for the relevant data. This species breeds once a year and the breeding season is lasting from August to January, mainly from September to December. The ratio of male/female during breeding season is 1.3/1. The females lay a number of 483 – 968 eggs per clutch (average 795 eggs, n = 30). The relative reproduction is 4 – 6 eggs (average 5 ± 1) eggs per gram of the body weight.
