“…Based on the results of the lethal dose test in table 4, the infection of koi fish was carried out through immersion with a bacterial density of 10 7 cells/ml E. tarda for 72 hours or 3 days. This is following the opinion of Narwiyani and Kurniasih (2011) where the mortality rate of the test fish is correlated with the increasing concentration of bacteria infected with the fish. Clinical symptoms that arise in fish infected with E. tarda are reddish lesions on the tail and fins, reduced fish appetite, sluggish movement, and reduced response to given stimuli.…”

The increase in koi fish cultivation can lead to increase risks and caused problems. The main problem is high disease attacks caused by the bacteria Edwardsiella tarda. One of the alternatives to control the disease is immunostimulant treatment with the use of maggot, Hermetia illucens Larvae, known as Black Soldier Fly (BSF). This study aims to report the effect of maggot as a substitute for koi fish feed formulations on the immune system of koi fish infected with E. tarda. This study used a descriptive method, by quantitative approach with the IL-6 and IFN-Ɣ expression through RT-PCR analysis and fish survival rate (%). Identification of E. tarda was carried out by the PCR test method at a molecular weight of 200 bp. The density of bacteria that caused the death of the 50% koi fish population (LD50) for 72 hours was 107 cells/ml. The highest IL-6 expression in the spleen was found in sample C of 28,844 and the lowest in-sample K (+) of 26,096. The highest IL-6 expression in the liver was in sample K (+) of 29,060 and the lowest was in sample D of 25,428. The highest IFN-Ɣ in the spleen was in treatment C, 28,844, and the lowest was in treatment D, 27,219. The highest IFN-Ɣ in liver was sample K (+) of 26,795, and the lowest in-sample C of 25,615. The survival rate of fish in this study reached 30%-100%. The optimal amount of substitution of maggot treatment is 75% (Treatment C) of fish feed.

“…In addition, the absence of clinical symptoms, there was also no mortality or 100% survival in silvers after infection with E. tarda, this could be due to the level of pathogenicity of E. tarda bacteria determined based on the ability of these bacteria to infect non-specific immunity in fish [30] and the level of bacterial pathogenesis based on the degree of compatibility of the host (susceptable host) [31]. In an unsuitable host, even though the bacteria is pathogenic for certain types of fish, it will not produce the same effect as a suitable host [32]. Host match rates can be receptor based [33].…”

Silver rasbora (Rasbora argyrotaenia) is a freshwater fishery commodity that has high economic value. However, fulfilling the demand for silver rasbora still relies on catches from nature, so cultivation is needed. The problem that occurs in the cultivation process is the Edwardsiella tarda infection which causes Edwardsiellosis disease. The purpose of this study was to determine the bacterial viability of E. tarda from silver rasbora after infection with immersion methods. The Total Plate Count (TPC) from blood, liver and kidney was taken from infected fish after 14 days immersion with bacterial suspension. The results showed that E. tarda infection had occurred in the blood, liver and kidneys as indicated by an increasing the density of bacteria in each organ along with the increasing of the concentration of infected bacteria. The highest density of E. tarda bacteria infected in silver rasbora was in the blood and the least was in the kidneys.

“…The observation of clinical symptoms showed that koi fish infected with E. tarda showed several clinical signs, including fast operculum movements, irregular and slow swimming, and bleeding on the skin. Meanwhile, other sources said that goldfish and rainbow celebes infected with E. tarda showed clinical symptoms in decreased appetite (Figure 2), reduced reaction to stimuli, slow swimming, and lesions on the tail and fins (Narwiyani and Kurniasih, 2011).…”

Highlight Research Feeding of maggot flour formulations to koi carp infected with tarda Active compounds contained in maggot Clinical symptoms of koi carp infected with tarda Damage to the muscle and gill tissue of koi carp infected with E. tarda Abstract The problem that fishes farmers often face is disease. Maggot contains a high protein which ranges from 41-42%. Besides that, maggot also has a good effect on increasing the body resistance of fish. While the maggot provision fulfills nutritional need, it’s also expected to boost immunity against bacterial disease. One of which is Edwardsiella tarda, known to infect koi carp (Cyprinus carpio). Feeding of maggot flour at different doses, namely A (25%), B (50%), C (75%), and D (100%) was carried out to determine its effect on the histopathology of the muscles and gills of C. carpio infected with E. tarda. Water quality during the study obtained an average value, namely the temperature ranging from 26-27.5℃, pH 6.5-8.1, and DO 5.2-8 mg/L. Fish infected with E. tarda showed several clinical symptoms, including rapid operculum movement, irregular and slow swimming, and bleeding on the skin. The results of the histopathological analysis showed that in muscle and gill tissue, treatment C (75%) showed the lowest damage value among other treatments with an average score of necrosis 0.93, hyaline degeneration 1.33, and Edema 1.27. Average score of gill tissue damage was 0.9 fusion, 1.3 congestion, 0.9 hyperplasia. Based on this, the provision of maggot flour can be used to prevent infection of E. tarda against C. carpio.
