| Abstract | The study was an attempt to improve the spawning of Nile tilapia (Oreochromis niloticus) by synchronization. • Chinese carp pituitary gland at 0.10, 0.25 and o.50 mg PG/ 100g breeder, Human Chorionic Gonadotropin at 10, 25 , 50 add 100 10/ 100 g breeder and temperature manipulation were tested. The results showed that 0.10 , 0. 25 and 0 . 50 mg PG/100 g breeder did not induce tilapia to spawn but 25 and 50 lU HCG/100 g breeder successfully induced tilapia to spawn. Temperature manipulation by exposing experimental fish to cold water of 21-22 ํc did not induce tilapia spawning after 1 , 2 and 3 weeks of long term cold treatments. However, a short term cold treatments of 6 hours was successful . The results showed that exposing experimental fish to 6 hour of cold water temperature (21-22 ํc ) consistently gave a significantly higher spawning rate than the control treatment of non-exposure to cold water by about 10-25%. |
