Response of kutuklin hemaglutinin protein adhesion in koi fish (Cyprinus carpio) infected by Myxobolus sp.

Koi fish (Cyprinus carpio) cultivation is quite easy to maintain if it can look carefully at fish health well. The Difficulty in maintenance due to parasitic attacks is Myxobolus sp., and this parasite is capable of causing death in fish. Treatment of parasites attached to koi fish can be done by giving chemicals such as Pyrethrum. This research aims to determine the reaction of kutuklin hemagglutination adhesin to koi fish infected by Myxobolus sp. The method used is an explorative and descriptive by conducting an In-Vivo test on koi fish. The treatment is, healthy fish without drug as a control, healthy fish with a drug dose of 1 l/g feed, and fish were infected with a drug dose of 1 l/g. Observation is done by taking fish blood plasma in each treatment. The results showed that kutuklin was able to contribute to treating Myxobolus sp. However, it cannot restore such a healthy state. This is indicated by high (up to 1/1024 dilution) in the hemagglutination (HA) test of koi fish blood plasma. So, that kutuklin can be used as an immune suppressor (immunosuppressor).
