Abstract

ABSTRACT This research aims to determine the effect of natural  honey to male percentage of betta fish by masculinization. This researchwas conducted at FisheriesBasic Laboratory,  Faculty of Agriculture, Sriwijaya University on January– February 2018. This research  usedcompletely randomized design (CRD) with 5 treatments and 3 replications. The treatment in this research was4 day of betta fish larvae  that submersed in 5 ml/L  natural honey with different immersiontime.The treatmentconsisted of P0 (without natural honey), P1 (12 hours of immersion), P2 (16 hours of immersion), P3 (20 hours of immersion),and P4 (24 hours of immersion). The observed parameters were post-immersion survival percentage, percentage of male betta fish, post- rearing survival percentage and water quality. The result showed the percentage of male betta fish was 47,50 % (P0), 66,35 % (P1), 73,51% (P2), 75,37 (P3), and 85,14 % (P4). Water quality during maintenace were temperature 27,4-28,8 oC, pH 5,3-5,8, DO 3,43-3,59 mg/L and amonia 0’001-0,002 mg/L. Treatment of P4 (24 hours of immersion) indicatedthe best treatment with larval survival percentage andmale percentage were 90.00% and 85.14% respectirely. Keywords : Betta fish (Betta splendens), masculinization,natural honey

Abstract

ABSTRACT Fitoremediation is one of water quality management system by using water plant such as Hydrilla verticillata that is purposed to decrease organic materials. This research was conducted at Laboratorium Dasar Perikanan, Aquaculture Study Program, Faculty of Agriculture, Sriwijaya University,Indralaya on May – July 2016. The research based on a Completely Randomized Design with four treatments and three replications. The treatments were media without H. verticillata (P0), addition of H. verticillata as much as 85 ± 10 g (P1), 110 ± 10 g (P2) and 135 ± 10 g (P3). The parameters were water quality, survival rate and specific growth rate of catfish. The data were analyzed by regressions analysis, analysis of variance and least significant diference test. The result showed that the addition of H. verticillata could improved water quality. The treatment of addition ofH. verticillata as much as 135 ± 10 g (P3) has highest survival rate 95.49 %, spesific growth rate for length 1.53 %.day-1 and weight 5.25 %.day-1. Keywords: Catfish,  Hydrilla verticillata, Phytoremediation, Water Quality
