PRESSURE CANNING FISH AND SEAFOOD
Pressure canning is the only safe method for canning fish and seafood.
Only fresh fish should be canned and these should be bled and thoroughly
cleaned of all viscera and membranes when caught, or as soon as possible. To
prevent spoilage, keep fish and shellfish refrigerated or on ice to maintain a
temperature of 4°C (40°F) or below.
Altitude Adjustments
The processing times for pressure canning given in the specific recipes are for
altitudes of 304 metres or below. When processing at an altitude of 305 metres
or above, process at 103 kPa (15 psi). The processing time is the same at all
altitudes.
Canning Recipes: Fish and Seafood
Clams, whole or minced
Keep clams on ice until ready to can. Scrub shells thoroughly and rinse.
Hot Pack: Steam for 5 minutes and open. Remove clam meat. Collect and
save clam juice. Wash clam meat in salted water using 1½ to
3 tablespoons of salt per 4 quarts of water. Rinse.
Cover clam meat with boiling water with 2 tablespoons of lemon
juice or ½ teaspoon of citric acid per 4 quarts. Boil for 2 minutes
and drain. To make minced clams, grind clams with a meat grinder
or food processor. Heat reserved clam juice to boiling.
Pack clams loosely in hot jars, leaving 1-inch headspace. Add hot
clam juice and, if needed, boiling water, leaving 1-inch headspace.
Remove air bubbles. Prepare jar rims. Adjust two-piece lids.
Process at 69 kPa (10 psi), 250 ml jars for 60 minutes and 500 ml jars for
70 minutes. When processing at an altitude of 305 metres or above, process at
103 kPa (15 psi) for the same amount of time.
Fish (salmon, trout, steel-head, and other fish except for tuna)
Remove head, tail, and fins. Wash fish in cold water.
Raw Pack: Split fish lengthwise and then cut into lengths that fit the jar size
being used. Bones can be left in and skin left on, if desired. For
halibut, remove the bones and skin.
