To treat, isolate the infected fish with pond salt and vigorous aeration. Reevaluate Your Routine. The majority of common fish diseases can be prevented with routine maintenance such as partial water changes, water testing, filtration, aeration and of course population control.
In ponds fish diseases do not occur very frequently. However, there are a few riskful moments: If you introduce new fish to a pond, it may happen that one of the new fish is sickened for some illness as a result of which it will also infect other fish.
There are more than 100 known diseases and parasites that can infect most species of pond fish and Koi. Koi Diseases are the result of interaction between a host, a pathogen (a disease causing agent, like a bacteria, parasite, or virus), and the environment.
Ornamental fish kept in ponds and aquariums are susceptible to numerous diseases. In most ponds and aquariums, the fish are at high concentrations and the volume of water is limited. This means that communicable diseases can spread rapidly to most or all fish in the pond or tank.
Many pond owners believe that fish diseases are mainly introduced and passed on by sick fish. Fortunately this is very rarely the case and it’s mostly up to you whether your fish keep well and fit. More than 90 % of the diseases are caused by inappropriate living conditions, such as water values and inadequate nutrition!
Although fish diseases can occur anywhere, these problems most often occur in ponds where fish are intensively cultured (catfish ponds) for sale and not in a typical recreational pond environment. Fish diseases can be difficult to diagnose, and treating those diseases in ponds or lakes is generally impractical and costly.
Bacterial diseases are common in all fish and occur most often when environmental conditions, such as water quality, are not favorable. Inadequate oxygen levels in the pond can stress fish and make them susceptible to bacteria infections. These infections are often associated with spring die-offs in fish ponds.
Sick fish should be removed from the pond to a treatment container (e.g., an old wading pool or aquarium), whenever possible, to prevent disease spreading to the other fish. Make an un-iodized salt dip by using Pond Salt (available at your local pond retailer).
