Fish Disease = Stress Condition + Disease Agent

Stress is the main factor man has the most control over. Many disease causing organisms normally occur in the same environment as the fish. They usually only become a problem when present in significant quantities and/or stress occurs. Therefore, by controlling stress you can help maintain a healthy pond. Prevention is easier than treating your pond for disease.

Some causes of stress are:

  • High ammonia level
  • Low dissolved oxygen level
  • Handling and/or moving fish
  • Poor water quality
  • Crowding
  • Parasites
  • Too high / low water temperature
  • Other toxic chemicals (chloramines, oak blossoms, weed spray etc.)
  • Sharp edges in and around pond
  • Inadequate and improper nutrition
