Abstract: The present study was carried out to know the artificial breeding of Ompk pabda, Heteropneustes fossilis and Pangasius hypophthalmus using pituitary gland (PG) from June to August 2014, in the hatcheries in Jessore region. Brood stock of Pangus, Shing, and Pabda was developed in the hatchery. A total of 10 hatcheries were included in the study. Brood fishes were reared in the brood rearing pond by providing artificial diet for good health and full maturation. Brood fishes were injected with PG in different months June to August. Both male and female were injected with PG. In Pabda, Shing and Pangus first PG dose was applied at 8-10, 30-35 and 1-2 mg PG/kg of body weight of females respectively. After 1st PG dose of Pabda, Shing, and Pangus (6 hours later) female were treated with 2nd doses at 10-12, 60, 8-10 mg PG/kg of body weight, respectively. At the time of second dose of female, the males were also treated with single PG dose. The males of Pabda, Shing and Pangus were treated with 8-10, 30-35 and 1-2 mg PG/kg body weight respectively. It was observed that the female and male brood fishes eject eggs and milt within 12-14 hours respectively. Ovulation occurred in Pabda, Shing, and Pangus naturally after, 6-7 hours. The fertilized eggs of Pabda, Shing and Pangus were hatched within 22-24 hours. The temperature, pH, dissolved oxygen and transparency ranged from 22-34 0C, 6-8.5, 5-7.5 ppm and 22- 32 cm of the water of brood rearing ponds respectively. The average spawn production and body weight of female Pabda, Shing and Pangus were 11500/kg and 120/gm, 21000/kg and 130/gm, 44500/kg and 3.5/kg, respectively. The average fertilization, hatching and survival rate of Pangus (80%, 73% and 64%), Shing (73%, 68% and 58%) and Pabda (78%, 65% and 60%) respectively. The male and female ratio was maintained as 1:2 for each fishes.
