Water before feed — watch the pond first

Feed cannot fix water that is already stressing the fish. Low oxygen, a swing in temperature or pH, or a rise in ammonia cuts appetite, conversion, and survival. A short hungry morning is cheaper than a night of dead fish.

What to look at before you feed

• Early morning: surface gasping, unusual colour or smell, dead or listing fish, whether aeration is actually running.
• At feeding: do they come evenly, or do a few grab while the rest hang back?
• After feeding: uneaten pellets, cloudy water, foam.

Log pH, dissolved oxygen, and temperature on the existing water-quality action. Ammonia and nitrite when you have the kits. The log is the system of record — not a memory of “looked fine.”

If oxygen is low or fish are piping, start aeration, hold feed, and find the load: too many fish, too much leftover feed, a failed aerator, or a weather change. Do not add more pellets to “catch up.”

Species and climate set the numbers you treat as a warning. Learn the range your local extension or veterinarian uses for this water and this species.
