Fish Diseases and Parasites
Fish are constantly exposed to a wide variety of diseases and parasites that occur in surface waters. Fish are subject to infection by disease-causing viruses, bacteria, and fungi. Fish are also parasitized by tapeworms, trematodes (grubs), nematodes (roundworms), leeches, and lice. Most of these organisms normally occur at low levels in farm ponds and in limited numbers on the fish. Some parasitized fish in a pond are not unusual. However, large numbers of infected fish are cause for concern since slow growth, sterility, stunted populations, and massive fish kills may result from extensive diseases and parasite infestations.
Fortunately, fish diseases and parasites seldom reach epidemic levels, and sudden, large fish kills in farm ponds are rarely caused by diseases or parasites. Fish suffering from diseases or parasites usually die slowly, a few fish each day. Only in severe cases when fish are in poor condition, starving, crowded, injured, mixed with wild fish, or stressed by rough handling, low oxygen levels, high temperatures or chemical toxins, do diseases and parasites become a serious problem.
Some early warning symptoms of fish suffering from disease or parasite infections are:
Discoloration, open sores, reddening of the skin, bleeding, black or white spots on the skin
Abnormal shape, swollen areas, abnormal lumps, or popeyes
Abnormal distribution of the fish such as crowding at the surface, inlet, or pond edges
Abnormal activity such as flashing, twisting, whirling, convulsions, loss of buoyancy
Listlessness, weakness, sluggishness, lack of activity
Loss of appetite or refusal to feed
Fish exhibiting any unusual form of behavior should be closely examined for external signs of disease or parasites. Infected fish usually show visible sores, discoloration, bleeding, swollen areas, lumps, popeyes, small black or white spots, or other abnormal growths on the head, body, and fins. Sick fish look and act abnormal.
There are few practical methods for treating diseased or parasitized fish in natural pond, lake, or stream waters. Sick fish can be effectively treated in hatcheries and aquariums under controlled conditions. However, in natural waters it is almost impossible to eradicate a disease or parasite without draining, drying, and disinfecting the pond bottom soil and destroying all the fish. Therefore, pond owners should make every attempt to prevent fish diseases and parasites from becoming a problem by:
stocking only healthy fish from disease-free commercial hatchery stocks
excluding all wild fish from the pond
preventing the transfer of fish from other ponds, lakes, or streams
following the stocking recommendations to avoid overcrowding
preventing fertilizer, animal waste, or pesticide runoff into ponds
not overfeeding pond fish
