Abstract

Water quality plays an important role in aquaponics system. Water chemistry parameter that may affect water quality is total organic carbon. Sources of carbon in the aquaponics system mainly derived from the decomposition of organic matter which derived from artificial feed and plant respiration. The research was conducted to study the reduction of total organic carbon concentration in the aquaponic system and the relation of abundance and diversity of phytoplankton. This research using different amount of ipomoea (Ipomoea aquatica) consist of 10, 20, and 30 rods and control treatments which use without ipomoea. The results showed that all of ipomoea treatments can reduce the amount of total organic carbon concentration in the aquaponics system. This research showed that nutrients cycle in the aquaponics system, especially total organic carbon dissolved in water is influenced by many factors such as plants, fish and primary productivity which determined by the plankton. Furthermore, a positive correlation occurred between total organic carbon concentration of the abundance and diversity of phytoplanktons (r = 0.5925; r = 0.6364). These results can be used for preliminary study of nutrient cycle model in aquaponic system.

Abstract

Aeromonas hydrophila is very potential to be used in vaccines and disease control MAS (Motile Aeromonas Septicemia) caused by the bacteria. However, strains of A. hydrophila bacteria which have high immunogenicity limited. Not to mention, in the field often decrease the pathogenicity of the bacteria as vaccine material resulting in a decrease in the immunogenicity of a vaccine made. Therefore, it is necessary to inventory and collecting strains of A. hydrophila bacteria potentially good that vaccination continuity can be maintained. This study used an experimental method with a completely randomized design (CRD), with treatments such as P1: A. hydrophila vaccine strain GPL-05; P2: A. hydrophila vaccine strain GL-02; and P3: control (PBS), with five replicates.This study aims to assess the potential immunogenicity A.hydrophila bacterial strains as vaccine candidates. Test fish used is African catfish was about 2 months with a length of 10-15 cm and width 15-20 g. The main parameters are observed antibody titer and cross-reaction test, while supporting parameters are parameters of water quality include water temperature, pH, dissolved oxygen. Antibody titer data was analyzed by Analysis of Variance (ANOVA) and Duncan's Multiple Range Test (DMRT) at the test level of 5%, while the data and the results of cross-reaction of water quality parameters observed descriptively. The results showed that the bacteria A. hydrophila strain GPL-05 and GL-02 has a high immunogenicity, thus recommended a candidate vaccine.

Abstract

Patin Siam (Pangasius hypopthalamus) is a freshwater fish which is received considerable attention by public and has high economic value. In process of cultivation, farmers often got problems because of high price of feed. It’s because raw materials feed such fish meal still import from another country. One of the efforts to reduce the use of imported fish meal is using Petek fish meal. The aim of this research was to determine the effect of the use of Petek fishmeal as partial substitution of fish meal. This research used Completely Randomized Design (CRD) with 5 treatments and 3 replications namely treatment A (commercial pellets / control), B (fish meal 75% + Petek fish meal 25%), C: (fish meal 50% + Petek fish meal 50%), D (25% fish meal + 75% Petek fish meal) and E: (0% fish meal + Petek fish meal 100%). Observed variables were absolute growth, daily growth rate, survival rate, and feed conversion ratio (FCR). Data were analyzed by ANOVA and Duncan test. The tested fish were cultivated in aquarium with dimension of 60 x 40 x 40 cm3 for 50 days. Fishes were feed three times a days with feeding rate of 5%. The results showed that the use of Petek fishmeal in feed could increase absolute growth and daily growth rate. The treatment of C resulted in highest absolute growth of Patin Siam and lowest feed conversion ratio. The treatments did not effect the survival rate of Patin Siam.

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.
