This research was conducted with the aim to analyze the presence of potential pathogenic bacteria in carp that are sold live in supermarkets in the city of Cimahi and to find out the species of these bacteria. Fish samples were obtained from two supermarkets in Cimahi City, Transmart and Superindo. From each supermarket three fish samples were taken once a week and repeated three times. Bacteria were isolated from several parts of the fish body namely body surface mucus, gills, liver, and kidneys. The results of isolation from each target organ were biochemically tested to determine the species of bacteria. Potential pathogenic bacteria found in carp from this research are Aeromonas hydrophila, Aeromonas sobria, Aeromonas schubertii, Aeromonas media, Aeromonas caviae, Aeromonas ecrenophila, Pseudomonas stutzeri, Pseudomonas pseudoalcaligenes, Pseudomonas aeruginosa, Aeromonas caviae, Aeromonas ecrenophila, Pseudomonas stutzeri, Pseudomonas pseudoalcaligenes, Pseudomonas aeruginosa, Plesiomonas shigelloides, Bacillus megaterium, Bacillus thuringiensis, Neisseria mucosa, Citrobacter freundii, Serratia marcescens, Staphylococcus epidermidis, Micrococcus luteus, Enterobacter aerogenes, and Enterobacter sakazakii.

Feed greatly affects the growth and health of fish, however it also functions to increase the value of the color intensity when specific additional ingredients are added. One of the important ingredients, marigold-meal is one of the natural carotenoid sources. This research aims to determine the optimum concentration of marigold-meal in the artificial feed to increase the intensity color of koi fish, specifically the kohaku strain. The method used was an experimental Completely Randomized Design, consisting of five treatments and four replications. Parameters observed were color intensities analyzed using Kruskal-Wallis analysis, if there were significant differences, Z test would be performed. Research results were the color intensity enhancement of koi fish tails and head until the 40th day showed the highest value in the treatment concentration of 0.0% marigold-meal (positive control) with an average score of 8.00 and 10.00. This value was not different from the treatment concentration of 2.0% marigold-meal and concentration 1.5% marigold-meal. However, this value was not significantly different from concentration of 1.5% marigold-meal. The lowest average score on the tail and head was treatment concentration of 0.0% marigold-meal (negative control). The optimum concentration of the addition of marigold-meal resulting the best color intensity increase was in 1.5% concentration of marigold-meal with the color intensity value of 5.97 in the tail and 6.50 in the head of koi fish Kohaku strain.

This study aims to see the condition of hematocrit levels and differential leukosit after immersion in LAB isolated and after in vivo, using Aeromonas hydrophila bacterium. LAB isolated were obtained from the organs of the common carp intestine. The study used a Completely Randomized Design (RAL) consisting of four treatments and three replications. The treatment used was immersion of test fish for 24 hours in several isolates of LAB with a density of 108, namely A: without LAB isolate (control), B: isolate CcB7, C: isolate CcB8, D: isolate CcB15. Immersion was done three times, with a frequency of seven days. Parameters observed included hematocrit levels, leukocyte differentiation and survival rate. The results showed that immersion in LAB isolate CcB15 will enhance the differential leukocytes and hematocrit levels that serve as indicators of carp body resistance, which is shown by high levels of white and red blood cells.
