Why is King Salmon So Expensive?

Because King Salmon populations are not as abundant as other species of salmon, they tend to be pricier. Their natural habitat, including rivers and oceanic regions, is limited and smaller populations make them less readily available.

Another factor that increases King Salmon costs is its high nutritional value, making it a sought-after choice for health-conscious consumers.

Finally, the methods used to catch King Salmon can also impact its price.

Regulations and quotas imposed on fishing King Salmon populations can limit the overall supply, contributing to the higher cost.

How to Store King Salmon

Proper storage of King Salmon is crucial to maintain its freshness and quality. Here are some guidelines on how to store King Salmon:

Fresh King Salmon

If you plan to use the King Salmon within a day or two, store it in the coldest part of your refrigerator at a temperature of 32°F to 38°F (0°C to 3°C). Keep the fish wrapped tightly in plastic wrap or an airtight container to prevent air exposure and cross-contamination with other foods.

To extend the freshness of fresh King Salmon, place it on a bed of ice in a shallow dish or tray, ensuring the fish is not in direct contact with the melting water. Seal the fish in a plastic bag to prevent direct contact with the ice.

Frozen King Salmon

When storing frozen King Salmon, first rinse the fish under cold water and pat it dry. Wrap the fish tightly in plastic wrap, foil, a freezer-safe, airtight container, or a freezer bag. Remove as much air as possible to prevent freezer burn. Label the packaging with the date and use it within 2 to 3 months for optimal quality.

For longer-term storage, consider deep freezing the King Salmon. Place the wrapped fish in the coldest part of the freezer at a temperature of 0°F (-18°C) or below. Deep freezing preserves the fish's texture and flavor for an extended period, up to several months.

Regardless of whether the King Salmon is fresh or frozen, it's important to follow safe food handling practices. Before storing or cooking King Salmon, inspect it for signs of spoilage, such as an off-putting odor, sliminess, or discoloration. If the fish appears questionable, it's best to discard it to avoid any health risks. Learn how to tell if salmon’s gone bad in our guide.
