Yes — small amounts of plain, fully cooked fish are safe and provide protein and omega-3s. Keep it occasional and unseasoned.
Keeper's noteA flake of plain cooked salmon now and then is a healthy treat. Avoid canned fish in brine (salt) and anything battered or fried.
What to watch out for with fish
Cooked fish is a safe, nutritious animal protein for parrots, and oily fish like salmon add beneficial omega-3s. The cautions are practical: fully cooked only (never raw), no salt or seasoning, bones removed, and modest portions. For larger species, mercury accumulation in big predatory fish is a reason to keep it occasional rather than frequent.
How to serve it
Plain, fully cooked, deboned; no salt or oil.
Small amounts occasionally; prefer low-mercury fish.
