Canning tuna @ home
The general rule of thumb is that 1 pound of fish on the fin will yield approximately 1/2 pint. However you might get more if the fish is larger and also if it is professionally filleted.
If you have other questions you might want to call the OSU Extension Food Preservation Hotline which opened today. It is open M-F from 9 am-4pm through mid October and answered by certified Master Food Preserver Volunteers. The number is 1-800-354-7319. Good luck and enjoy canning tuna.
