Abstract

Extract of the pituitary gland can affect gonad maturation through control of GnRH and LH release, which hypothalamus releases GtH, and subsequently pituitary gland secretes luteinizing hormone (LH) triggerring steroid hormones on gonad final maturation. The specific objective of this study was to examine the effectiveness of the pituitary gland extract for final gonad maturation of climbing perch fish. Benefit of this research was as a contribution to the technology development of climbing perch fish breeding on peat swamp waters. Administration of pituitary gland extract 0.002 ml/g the increase in final total diameter distribution proportion climbing perch fish egg 0.7 mm by 80%, egg nucleus position proportion into germinal vesicle breakdown (GVBD) by 85% and increase the value of GSI that was 4.7%. Keywords : Pituitary gland extract, final gonad maturation.

Abstract

The research implemented in wet labs Department of Fisheries Faculty of Agriculture University of Palangkaraya with the allocation of time of 40 days commencing from February, 27th 2019 to april,7th 2019. This study aimed to the effectivity of ginger (Curcuma xanthorrhiza Roxb) of the survival tilapia (Oreochromis niloticus). The research used a pool tarp that is given nets 12 units with a size of 1x1x1 meters and filled with fish samples as many as 40 fishes/net. Fish samples used are tilapia fish with a size of 2 to 3. The experimental design used is RAL (completely randomized design) with 4 treatments with 3 replications. Treatment A (control), treatment B (addition of ginger 3 g/kg feed), treatment C (the addition of ginger 6 g/kg feed), and treatment D (addition of ginger 9 g/kg feed). The results determine the effect of ginger treatment D (additions ginger 9 g/kg feed) in increase survival rate that was 84.1% and growth relative weight that was 1966.72% and the value feed conversion 3.1. Keywords : Ginger, survival rate, tilapia fish.
