Abstract

The effect of glycerol at the TSB media on Aeromonas hydrophila bacteria viability was studied. The purpose of this study was to obtain the best glyserol concentration in TSB as storage media for Aeromonas hydrophila bacteria. The completely randomized design with one factor was used for four treatments and three replications, i.e., TSB media added glycerol 10%, 15%, 20% and 25%. The stage of this research included media preparation, preliminary test, glycerol preparation, inoculation on kryotube, and test bacteria inspection. The test results showed the highest bacteria growth capacity was found on bacteria stored in TSB that was added with glycerol under concentration of 15%, namely 5.77 x 107 CFU/ml and the lowest one in TSB that was added gluserol 25%, experiencing total death on 56th day. The largest percentage of bacteria viability during storage was obtained on 15% glycerol increment, accounting for 0.01015%, and the lowest one was found on 115% glyserol increment, namely 0%. The aeromonas hydrophila bacteria storage with using glycerol concentration for 10%, 15%, 20% and 25% on temperature -20o C during 56 days did not cause to be occured mutation and change the bacteria charactristics. Percentage of suitable bacteria on mother T (0) was 100%.

Abstract

This study was conducted commencing on October 8, 2013 until December 7, 2013, at the hatchery Faculty of Agriculture, University of Islam Riau Pekanbaru. This study aimed to determine the effect of probiotic viterna on artificial feed on fish growth Mystus nemurus. This study used a completely randomized design with 4 treatments: P0 without treatment (control), P1 addition of probiotic viterna 2 cc/kg of feed, P2 4 cc/kg of feed and P3 6 cc/ g of feed. Fish samples used are fish seed baung 2 months old with an average weight of 3.0 g and 6.0 cm long. The container used in this study is the cage net with a size of 1 x 1 x 1.2 (m) 12 units. Analysis of data using analysis of variance with 5% confidence level. The results showed that the addition of probiotic treatment viterna the best feed in the treatment of 6 cc/kg of feed and the addition of probiotic viterna no significant effect on the growth of the absolute weight, daily weight growth rate and feed conversion rate baung fish.
PENGARUH PEMBERIAN HORMON TIROKSIN (T4) DENGAN PERENDAMAN TERHADAP PERTUMBUHAN DAN TINGKAT KELULUSHIDUPAN BENIH IKAN GURAMI (Osphronemus gouramy Lac) Oki Kurniawan; T Iskandar Johan; Jarod Setiaji

Abstract

The objective of this research was to examine the effect of giving tyroxin hormone (T4) with soaking on growth and survival of gouramy seed (O. gouramy Lac). The research was conducted at the Hatchery Faculty of Agriculture Riau Islamic University Pekanbaru from October to November 2009. Method used was experiment. Treatment consisted of P1 (without tyroxin hormone), P2 (0.3 mg/3 l water), P3 (0.9 mg/3 l water) and P4 (1.5 mg/3 l water). The resuts showed that the highest absolute growth weight was found on P4 of about 1.11 g, the highest absolute growth lenght on P4 of about 0.93 cm, and the highest daily speed growth on P4 of about 2.9%. The survival rate was found to be 100% for the whole treatments. The variation analysis was obtained that the use of tyroxin hormone with different dosages had no significant effect on growth rate of weight and lenght for gouramy seed.

Abstract

Meniran (PhyllanthusniruriL) solution test for the treatment measures of Clariasgariepinus which was infected by bacteria Edwardsiellatarda was conducted. The purpose of this study was to find the effective concentration of the solution meniran for prevention of red spot disease (edwardseliosis) that infect catfish. The completely randomized design with 4 treatments and 3 replications was used. The treatment was worked by soaking in a solution with meniran concentrations of 3,000 ppm, 5,000 ppm, 7,000 ppm and without being given meniran solution as a control. The average of meniran solution inhibition against bacteria at concentration of 50,000 ppm of 14.3 mm, concentration of 25,000 ppm of 12 mm, concentration of 10,000 ppm of 8.7 mm and concentration of 5,000 ppm of 6 mm. Meniran L D50 concentration test of 40,000 and 60,000 on the 24-hour immersion caused death by 10%. The highest survival rate was found at a concentration of 7,000 ppm as 86.67%.

Abstract

This study aimed to investigate the effect of the hormone thyroxine (T4) on the survival and growth of fish seed jambal conjoined. The method used was experiment with completely randomized design with one factor and four treatments. The observed parameters were the absolute weight growth of fish seed jambal, the total length growth, the growth rate of daily weight percentage, and survial rate. The treatment consisted of P1 (without the hormone thyroxine), P2 (soaking with hormone thyroxine at a dose 0.2 mg / 2 liter), P3 (soaking with hormone thyroxine at a dose of 0.6 mg / 2 liter), P4 (soaking with hormone thyroxine at a dose of 1.0 mg / 2 liter). The observation results showed that the best dosage was found on soaking treatment with hormone thyroxine 1.0 mg/2 liter. On that treatment, the growth of the absolute weight of jambal siam fish seed reached 7.04 g, the absolute length growth of 3.07 cm, the growth rate of daily weight percentage of 15.91% and survival rate of 100%.
