Abstract

The purpose of this study was to determine the effectiveness of the stimulation of carp pituitary extract on the spawning of climbing perch and also to determine the effectiveness of the use of natural food results from fertilization to climbing perch larval survival. After the granting of pituitary extract increased the diameter of the eggs at the end of treatment A (0.70 mm) = 125 eggs, treatment B (0.70 mm) = 125 eggs, treatment C (0.70 mm) = 135 eggss. While climbing perch without pituitary extract (treatment D) egg at the end diameter there is still a size 0.50 mm = 4 eggs, 0.60 mm = 87 eggs and 0.70 mm = 109 eggs. After mixing climbing perch brood, the treatment A, B and C courtship and spawning occurs as a result of gonadotropin stimulation by the pituitary gland extract. Relative growth rate of climbing perch larvae given natural food reared for 1 month ranged 11208.00% - 6982.61%. Relative growth rate fastest in treatment C fed with 60 liters of filtered with an average relative growth rate 11208.00%. Treatment A and B decreased the relative growth rate, because natural food given limited and may not be used for growth.

Abstract

Extract of the pituitary gland can affect gonadal maturation through control of GnRH and LH release, which hypothalamus releases GtH, and subsequently pituitary gland secretes luteinizing hormone (LH) triggerring steroid hormones on final maturation. The specific objective of this study was to examine the effectiveness and efficiency of the pituitary gland extract for spawning of climbing perch fish. Benefit of this research was as a contribution to the technology development of climbing perch fish hatcheries on peat swamp waters. Usage of pituitary gland extract 0.002 ml/g can speed up the time of ovulation of climbing perch fish 3.77 hours, increase the value of GSI that was 4.72%, and can increase the amount of egg spent on spawning as many as 2915.
