A study on the factors affecting the hatching success of river terrapin (Bat Agur affinis) egg in artificial pond
The Batagur affinis is southern river terrapin, a type of turtle under the Batagur family found in Malaysia, Indonesia, and Cambodia. In Malaysia, this species is found in large river with noticeable number in Perak, Terengganu and Bukit Penang, Kedah River. The Batagur aifinis considered threaten a...
