Abstract: Induced breeding of climbing perch, Anabas testudineus (Bloch, 1792) was done in aquaria in the laboratory using carp pituitary extract. An intramuscular injection was given with the single dose of 50 mg and 100 mgkg-1 body weight in males and females respectively. The female brood responded to lay eggs at 8-10 h latency period. The breeding performance and fertilization rate was higher when two males were used for every female. The present study observed fertilization rate of 96 ± 1.41and 84± 1.41 while male and female ratio was 2:1 and 1:1 respectively. The first cleavage began at a 20 min after fertilization. The morula, blastula and gastrula stage was completed at about 4 h, 5 h and 30 min and 7 h and 30 min respectively after fertilization. The details of fertilized eggs, cleavage and developmental stages are documented with photograph. Healthy larvae hatched after 21-22 h.
