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

Combination supplementation of probiotic Saccharomyces cerevisiae and MOS prebiotic applications on a laboratory scale had been performed and was able to improve survival rate, growth and immune response of Pangasius sp. against multiple pathogens. The purpose of this research was to test the effects of combination probiotic Saccharomyces cerevisiae and MOS prebiotic administration on growth performance of Pangasius sp. reared in ponds (net cages 1x1x1 m3) on field scale. Fish with initial average weight 2-3 g that has been reared for 30 days was reared in fish pond in stocking density of 80 fishes/m2. This research consisted of two treatments with three replications: K treatment (without synbiotic administration) and P treatment (administration of probiotic Saccharomyces cerevisiae and MOS prebiotic for each 0.2%). The results showed that synbiotic administration was able to improve the survival rate, daily growth rate, feed conversion ratio, feed efficiency and weight gain of Pangasius sp.
