POTENSI KULIT BUAH MANGGIS (Garcinia mangostana L) YANG DICAMPUR DALAM PAKAN UNTUK MENINGKATKAN KETAHANAN TUBUH DAN KELULUSHIDUPAN IKAN LELE DUMBO (Clarias gariepinus) TERHADAP PENYAKIT Motile Aeromonas Septicemia

Abstract

This research was conducted on 12^th May until 23^rd July 2015 held at Parasite and Fish Disease Laboratory. The aims of this research was to determine the potency of mangosteen pericarp (G. mangostana L.) in feed to increase immunity of African catfish (C. gariepinus) on Motile Aeromonas Septicemia disease seen from the hematology parameters. The treatments were addition of mangosteen pericarp in feed with different concentration i.e : Kn (without mangosteen pericarp), Kp (without mangosteen pericarp and injected using A. hydrophila), P₁ (addition mangosteen pericarp 2 g/kg of feed and injected using A. hydrophila), P₂ (addition mangosteen pericarp 4 g/kg of feed and injected using A. hydrophila) and P₃ (addition mangosteen pericarp 6 g/kg of feed and injected using A. hydrophila). Fish were maintained for 60 days. After 60 days treatment the fish were intramuscularly infected with A. hydrophila with density of 10⁷cell/ml in a dose of 0,1 ml/fish. The best results showed that addition mangosteen pericarp in P₃ treatment after challenged with A. hydrophila significantly different on haematocrit levels (22,94%), total leukocytes (104,83×10³ cells/mm³), phagocytic activity (64,80%), and survival rate (100%). Total eritrocytes were not different significantly between treatment with 2,04×10⁶ cells/mm³.
