Abstract

Pacific white shrimpculture is having problems caused by bacteria infection. The cause of  bacteria infection is V. harveyi, it can decrease seed production. Pathogenicity of vibriosis can decrease with inhibition by other types of  bacteria. The aim of the research was to get competitor V.harveyi isolates through identification and challenge test in vitro and in vivo. The result of screening of bacterial isolates were obtained from cultivation supplement products to produced 4 pure isolates with different morphologically colonies and cells. There was one potential isolate could inhibits V. harveyi by inhibition test in vitro. Biochemical test from three different  laboratories were identified that Acinetobacter sp. as competitor to V. harveyi and it was not pathogenic to Pacific white shrimp. Challenge test Acinetobactersp. against V. harveyi on Pacific white shrimp larvae was conducted through three treatments, without given V.harveyi and Acinetobacter sp. As controls; treatment with given bacteria V.harveyi and treatment with given V. harveyi and Acinetobacter sp. The challenge test results showed that treatment with given of V.harveyi and Acinetobacter sp. may decreased V. harveyi density of 6.3x106CFU/mL to 7.5x103CFU/mL which could suspected to decrease pathogenicity of competition number of colonies.

Abstract

Isolate D2.2 is a bacterial isolate with 97% homology level with Bacillus sp. This isolate is a biocontrol bacterium capable of inhibiting the growth of Gram positive bacteria and Gram negative bacteria. The use of biocontrol bacteria is one solution of disease problem in cultivation organism. Prior to being applied to the field, D2.2 isolates need to go through a series of tests, one of which is growth kinetics testing under various environmental conditions, such as different degrees of pH and salinity. This is because environmental factors can affect the rapid growth of bacteria. The purpose of this study was to study the bacterial growth kinetics of D2.2 at different pH and salinity. The growth kinetics was observed by measuring optical density (OD) through a method of turbidimetry using a spectrophotometer at a wavelength of 625 nm to the stage of death. The results showed that the fastest growth rate was found at 20 ppt salinity with 0.179 h-1 and generation time of 5,588 hours. While in all pH treatments, generation time and growth rates achieved all treatments have the same pattern.

Abstract

 Catfish (Pangasius sp.) Is one of the most cultivated freshwater fish, because it is one of the fish that has a high economic value. However, the use of phytopharmaca is used to improve feed efficiency and fish growth. One of the phytopharmaca which can be used as an antimicrobial is temulawak (Curcuma xanthorrhiza Roxb). This study aims to determine the optimal dose of the effect of temulawak extract on artificial feed in increasing feed consumption, efficiency of feed utilization, and growth rate of catfish (Pangasius sp.). The test fish is maintained with a stocking density of 1 tail / l with a maintenance time of 42 days. This study used an experimental method with 4 treatments and 3 replications. The treatments in this study were Treatment A (addition of 0 ml ginger extract), B (addition of 6 ml temulawak extract), C (addition of 12 ml curcuma extract), and D (addition of 18 ml ginger extract). The data observed included absolute weight, crime scene, EPP, SGR, REP, SR and water quality. The results showed that the addition of temulawak extract to artificial feed had a very significant effect on absolute weights, crime scenes, EPP, SGR, REP but did not differ significantly for survival. The optimum dose of addition of curcuma extract to total feed consumption is 11 ml capable of producing a maximum crime scene of 168.1 g, efficiency of feed utilization is 10.5 ml capable of producing a maximum EPP of 70.3% and specific growth rate is 10.8 ml resulting in maximum SGR 2.46% / day

Abstract

Vaname shrimp (Litopenaeus vannamei) is one of the main aquaculture commodities in Indonesia because it has high economic value. But in the aquaculture it is known that there are diseases that cause death in shrimp before harvest time. Vibriosis is a disease caused by the Vibrio parahaemolyticus, bacteria which often attacks shrimp culture. Population control of Vibrio sp. done by giving immunostimulants and vaccines, as well as giving feed plus antibiotics. However, continuous use of antibiotics and improper doses will cause bacteria to become resistant and cause residues in the tissues. This study aims to examine the effect of Avicennia sp. fruit extract in preventing the infection of Vibrio parahae-molyticus in vaname shrimp on a laboratory scale. This study used the experimental method Complete Random Design (CRD), which consisted of five treatments with different concentrations of Avi-cennia sp. fruit extracts and three replications of individuals in the population. The results showed that Avicenniasp. fruit extract Avicennia sp. able to influence the inhibition of the growth of Vibrio parahaemolitycus bacteria and prevent the occurrence of vibriosis disease . This can be seen by the value of Relative Percent Survival (RPS) which is limitited to 50%, can slow down the time of death of the shrimp seen from the Mean Time to Death (MTD), and followed by a high  Survival Rate (SR). The concentration that most affected the treatment was the concentration of 350 mg/l.Keywords: Avicennia sp extract, vaname shrimp, Vibrio parahaemolyticus
