Frequently Asked Questions (FAQs)

1. Are Frozen fish fillets healthy?

Frozen fish is just as nutritious as fresh fish, according to the Natural Fisheries Institute. For fish that is properly frozen right after harvest, like our barramundi, the nutritional value, moisture, and taste is completely preserved.

2. Can you cook fish fillets from frozen?

It's true, you don't! You can skip the thawing process altogether and cook frozen fish straight from the freezer. You'll have to add a few minutes to the cook time in your recipe to account for the lack of thawing, but you can poach, steam, bake, broil or grill fish straight from the freezer!

3. Is Frozen fish worse?

"There really is no difference," said Gibbons. "The clock never moves backward when it comes to freshness. If a fish is caught, handled well and frozen immediately, you literally stop the clock. You freeze in the freshness." He adds that nutritionally, nothing is lost when fish is frozen.
