How do you treat a fish wound?

When caring for fish wounds, it is important to be aware of the normal behavior of fish and the anatomy of fish skin. Fish instinctively secrete a glycoprotein compound to heal minor cuts and abrasions.

This compound, known as mucin, helps the skin to maintain a moist environment, prevents infection, and aids in the healing process. If a fish wound is not treated promptly, mucin production can cause the wound to become chronic, ulcerate, or even necrotic.

Once the wound has been identified, the first step is to clean the area. This can be done with a mild soap and warm water.

If the wound is large, it may be necessary to remove the fish and have it professionally treated. If the wound is small, a bandage or wrap can be applied to keep the area clean and protected.

If a fish wound is severe, it may require veterinary attention. In this case, the fish will need to be removed and the wound will need to be cleaned, disinfected, and then treated with a topical solution such as antibiotics or wound sealants.
