Blue, mackerel, salmon, steelhead, trout, and other fatty fish except tuna.

Caution: Eviscerate fish within 2 hours after they are caught. Keep cleaned
fish on ice until ready to can.

Note: Glass-like crystals of magnesium ammonium phosphate sometimes form in
canned salmon. There is no way for the home canner to prevent these
crystals from forming, but they usually dissolve when heated and are safe
to eat.

Procedure: Remove head, tail, fins, and scales. Wash and remove all blood.
Split fish lengthwise, if desired. Cut cleaned fish into 3-1/2 inch
lengths. Fill pint jars, skin side next to glass, leaving 1-inch headspace.
Add 1 teaspoon of salt per pint, if desired. Do not add liquids.

Adjust lids and process following the recommendations in Table 1 or Table 2
according to the canning method used.
