Treating
Ulcers in Koi and Injection Technique |
Subject is a 5
inch butterfly with a huge ulcer from the
dorsal fish back to the caudal fin.
Antibiotics used are Baytril and Amikacin.
Microscopic biopsies were negative for
parasites so I proceeded on the basis that
the fish is suffering from a bacterial
infection.

 This
is a small video of the ulcerated fish
swimming in a bucket of pond water.

Short
video of the fish being injected. In
the video you will see the anal opening (it
just looks like a dark spot in the video).
The tip of the needle is inserted to the
right and slightly forward of the anal
opening.

Note:
I highly recommend that you use anesthetic
to knock the fish out before attempting to
inject the fish! I have many years
experience injecting fish and am able to
hold the fish in one hand and inject with
the other. You can see how I was able
to flawlessly roll the fish over in one hand
in one smooth movement with out dropping the
fish so you the viewer can get a better view
of the actual ulcer.
The above
photos and video were done on Sunday August
30th and returned to the tank it came from.
Salt is slowly being brought up to .3 (3
pounds per 100 gallons). The
salt will help with the osmotic regulation
within the injured fish.
In two days the fish will be removed and new
photos taken so that you can see the healing process. I will make another
thorough assessment of the patient at that time. More videos and pictures
will be posted here.
