Why are there all these dead fish in my pond?
Fish kills are common occurrences in the winter and during particularly hot days during the summer. The most common cause is low dissolved oxygen (DO) levels in the pond. Cold weather also causes kills of fish with little tolerance for drops in temperature (e.g. tilapia).
