Fluke is a common parasite that is found in almost every kind of water. It affects the pond fishes and the problem the fishes face is called skin fluke and gill fluke. These minuscule species attach themselves to the body of the fish, and this is the way they feed themselves from the skin and gill tissue of the fish. This creature is microscopic so you can only find the issue if you scrap a piece of skin from the gill area and check that under the microscope.
You cannot identify a gill fluke in naked eye, as these are barely 3mm in length, slightly longer than the skin fluke. It has a cylindrical body shape and the head has a dark spot. A set of hooks called opisthaptor helps it to attach to the feeder or the koi fish.
Cause of Koi Gill Flukes
The gill fluke problem is mostly caused by the newly brought fishes in the ponds. Sometimes even the birds carry this microorganism when they come to drink water from the water body.
You can find the worm part of the fluke stuck in the skin of the fish and then you need to apply certain kind of drugs to eliminate the ailment. This is a kind of parasite and it stays on the body of the fish until you notice it and omit it by antifungal or antibacterial medicine.
The flukes are not fed on any particular fish for a long time and eventually leave its feeder. At the early stage of life a koi fish may get infected with this parasite.
They cause irritation and inflammation to the part they are stuck, like the gill. The koi starts eating less and feeling lethargic due to the stress, which may later cause serious illness. The problem can grow if the number of flukes gets increasing. Its health will worsen and it will spread this parasite to other fishes of the same pond. So if you realize any strange acting in a single koi of your pond, start looking for reason behind it before it starts spreading.
