There were eighteen females (76± 4 g) and thirty-six males (35 ± 5 g) injected by Anabas testudineus and Cyprinus carpio male pituitary extract with three level dosages 5, 10, and 15mg kg-1 of fish body weight to find out the effect of donor and dosage of pituitary extract on ovulation and hatchability of climbing perch egg. Nested design with two factors and three replications used in this research. The data were analyzed by analysis of variance (anova),Honestly Significant Difference (HSD), and regression. The result of this research has find out the range of latency time from 09,17 to 12,17 hours, fecundity from 9497 to 16668 eggs 100-1 g, fertilization rate from 90,00 to 98,80 %, incubation time from 20,10 to 21,45 hours, and hatching rate from 87,78 to 97,47 %. The result of anova indicate that pituitary gland extract donors have not effect (P > 0,05) on latency time, fertilization rate, incubation time, and hatching rate, but has effect (P < 0,05) on fecundity. The dosages of pituitary gland extract have not different (P > 0,05) on the incubation time, but have significantly different ( P <0,01) on latency time, fecundity, fertilization rate, and hatching ate. HSD test showed that climbing perch pituitary extract at the level of 10 mg kg-1 body weight is the best treatment.Regression analysis showed that the optimal dosage of climbing perch and common carp pituitary extract on hatching rate are 11,50 mg kg-1 and 12,47 mg kg, respectively.Keywords: ovulation and hatchability
