| Abstract: | The present paper deals with tha embryonic development on artificial fertilized eggs of Tor brevifilis brevifilis (peters) and the lowest temperature desured during the embryonic developent has been discussed .The fertilized eggs of this fish aze sticky , they are 1.7-1.9mm in diameter and 2.5-2.7mm in eggs expande with water. the yolk movement begins in early blastrula stage.The nean length of newly hatched larva is 6.6mm.At the water temperature of 20.5-23.0℃,the whole preocess of embryonic development losted for 71 hours and 7 minutes. |
