Season feed plan
An estimate of the feed your stock will need from stocking to harvest: stage by stage, which grade, how many bags, and a week-by-week schedule.
Estimate only. Assumes steady growth, comfortable water temperature and losses spread evenly across the season. Real ponds vary: always feed to what the fish clear in 20–30 minutes, and cut back in cold water or low oxygen.

Oxygen rule for today’s feed
Enter today’s dissolved oxygen to see which rule applies.
- Comfortable5 mg/L or moreFeed the full planned ration.
- Low4 to 5 mg/LFeed about 75% of the ration and watch the fish.
- Very low3 to 4 mg/LFeed about half, run the aerators, and test again.
- Criticalbelow 3 mg/LDo not feed. Aerate now and call your advisor.
General guidance, not a rule for every pond. Species differ — air-breathing catfish cope with lower oxygen, but uneaten feed still spoils the water. If in doubt, ask your advisor or fisheries officer.
Week by week
Expected average size mid-week and the feed that size needs. Re-weigh a sample every two weeks and follow your fish, not the calendar.
