The first step to koi parasite identification is taking a mucus sample or scrape. A mucus sample is examined under a microscope to correctly identify the exact parasite/s affecting your koi, so that the right treatment can be administered swiftly, saving time and money.
Taking a mucus sample/scrape is a simple task that all koi keepers will have to do at some point. It’s easy and quick, though can be daunting for beginner koi keepers. Done correctly, it poses very little risk to the koi.
You will at least need some basic pieces of koi handling equipment to safely take a scrape. A good quality net, bowl, and possibly a koi sock will be required. You will also need a plastic card (points card, fuel card, bank card etc), microscope slides and cover slips. It’s good to own a quality microscope, though borrowing from a friend or koi club, or bringing a sample in to our shop is an option.

Now you have your sample, it’s time to examine the mucus under the microscope!
