Abstract

The presence of vibrio bacteria in the breeding pond is one of the important factors that affect the activities of vaname shrimp breeding. Vibrio sp. bacteria in waters can cause losses if the number is above the threshold that should be. The high abundance of Vibrio sp. bacteria in the cultivation environment is an indicator that shows the potential for disease that can reduce the growth rate and survival of shrimp. The purpose of the study was to determine the abundance and dominance of vibrio bacteria in vaname shrimp breeding ponds using the TPC (Total Plate Count) calculation technique. The methods used include bacterial sampling, preparation of tools and materials, making bacterial culture media (NA and TCBS), dilution, bacterial inoculation, and calculating the number of bacterial colonies. The results of the calculation of bacterial abundance showed that there were 9 breeding ponds with different abundances. The highest abundance was found in pond BV1 with a total bacterial value of 9.6 x 105 CFU/ml. Meanwhile, the highest vibrio dominance was found in pond BV4 with a percentage of 43.69%.

Abstract

Eel (Anguilla sp.) is a leading freshwater fish commodity. In the intensivesystem, high stocking density results in high production costs. Maggot meal isan alternative raw material that has complete nutritional value such as fishmeal but is cheaper. The purpose of this study was to determine theeffectiveness of substituted fish meal with maggot meal on the growth andsurvival rate (Anguilla bicolor) Elver phase. The method carried out in thisstudy used an experimental method with a completely randomized design(CRD) consisting of 4 treatments and 3 replications with a combination of fishmeal and maggot meal, P0: 100% TI and 0% TM, P1: 80% TI and 20% TM,P2: TI 60% and TM 40% and P3: TI 40% and TM 60%. The results of rearingfor 60 days showed a significant effect on absolute weight growth, specificgrowth rate, and yield, while the yield had no significant effect on absolutelength growth, feed conversion, and survival. The results of the water qualityparameters of the media are temperatures ranging from 24 °C -29,8 °C, pHranging from 5,14-7,7, DO ranging from 2,4 mg/l – 5,1 mg/l and ammoniaranging from 0 ppm – 0,01 ppm.
