Abstract

High concentration of ammonia is one of major problem in common carp (Cyprinus carpio) culture. It was caused by high stocking density and excessive feed. Molasses is biologicaly and economicaly considered as one of the safest way to increase the water quality. The aim of the research were to understand to effect of different molasses concentration which was applied in probiotic on the water quality, growth and survival rate of cammon carp. The research used five treatments namely (A) 0 g/Lmolasses, (B) 2,4 g/Lmolasses, (C) 4,8 g/Lmolasses, (D) 7,2g/Lmolasses, (E) 9,6 g/L molasses. Data of temperature, pH, DO and daily growth rate were analyzed by using Kruskal-Wallis nonparametric test, while the ammonia and survival rate were analyzed descriptively. The results showed that (1) molasses treatment on the application of probiotics provides influence on the afternoon temperature, pH and dissolved oxygen (DO) in the morning and afternoon, concentration of ammonia and survival rate (2) based on the stability of temperature, pH and DO in the morning and the afternoon, concentration of ammonia, growth and survival rate of carp higher than the other. The concentration of 2,4 g/L molasses was considered as the best treatment.

Abstract

Common carp (Cyprinus carpio) is one of the consumption fish which has high economic value. However, the efforts to increase carp production obstracted by diseases such as furunculosis by A. salmonicida. So that we have to consider the disease prevention method which safer such as probiotic. The aims of this research were to know effect of the time administrations of probiotic on non-specific immune responses and to know the best time administration of probiotic on non-specific immune responses of common carp injected by A. salmonicida. The research was conducted from August to October 2011. The research used three treatments (without administration of probiotic, administration of probiotic once every day, and administration of probiotic once every five days) with four replications. Data of total leukocyte and percentage of differential leukocyte were analyzed by using ANOVA, while RPS and water qualities were analyzed descriptively. The results showed the time administrations of probiotic showed a real impact on improving non-specific immune responses characterized by increased total leukocyte in carp, administration of probiotic once every five days resulted better non-specific immune responses, which had been seen from the highest total leukocyte and the highest RPS after being injected by A. salmonicida.

Abstract

Common carp (Cyprinus carpio) is one of freshwater fish that growing very rapidly as a commercial fish. One of the factors that influence growth of common carp is water quality. Zeolite klinoptilolit were applied as filter in aquaculture water quality management. Zeolite was used to improve water quality, especially the consentration of ammonia. Zeolite works exploit the ability ion exchange of Na+ and K+, which is a cation that can be exchange serves to neutralize poisons in metabolism. The aim of this study are to know additional amount of zeolite that give the best result for decrease ammonia consentration at common carp culture. The experimental by used completely randomized design with 4 treatments.. The treatments were with addition zeolite of treatment B = 150 g; C= 300 g; D = 600 g, and treatment A without the zeolite addition. The results showed that the addition zeolite of 600 grams as a chemical water filter at common carp culture gave the best result for decrease ammonia concentration had a different effect on the concentration of ammonia was maintained for 60 days (P<0.05). However, the addition of zeolite as a water filter did not give different effects on absolute growth, daily growth rate, and survival of common carp (P>0,05).
