PENCEGAHAN INFEKSI Aeromonas hydrophila PADA IKAN PATIN (Pangasius sp.) MENGGUNAKAN TEPUNG PACI-PACI (Leucas lavandulaefolia)

Abstract

ABSTRACT

A. hydrophila is a kind of bacteria common found in freshwater fishes. Catfish (Pangasius sp) is one of freshwater fish which can be infected by A. hydrophila. The aim of this research was to know the effect paci-paci (L. lavandulaefolia) powder in feed to prevent A. hydrophila infection in catfish (Pangasius sp.). The research was conducted in Laboratorium Budidaya Perairan, Aquaculture Study Program, Agriculture Faculty, Sriwijaya University. Hematocrite examination was conducted in UPT Klinik Universitas Sriwijaya, Indralaya on April – Mei 2015. The research based on Completely Randomized Design (CRD) with five treatments and three replications were fish fed with addition of Paci-paci powder of 0%, 2%, 4% and 6% for 14 days then infected by A. hydrophila through injection as much as 0,1 ml/tail with density 1.74 x 10⁸cfu.mL^-1. Parameters of this research were prevalence, hematocrite concentration, survival, growth, food convertion ratio and water quality. The result of the research showed that addition of Paci-paci powder in fish ransom could prevent A. hydrophyla infection. Best dosage is treatment P3 (6%) that resulted prevalency 38.80%, survival rate 75%, food convertion ratio 1.14 and had highest growth of fish which is on H1-H14 absolute weight growth and absolutely length is 7.25 g and 1.6 cm. At H16-H30 absolute weight growth and absolutely length is 5.96 g and 1.00 cm.
