We may receive a commission on purchases made from links.

Coastal states are typically spoiled with delicious seafood options, while other regions get by with what's available, but Costco levels the playing field somewhat. The big box store has long been a destination for seafood aficionados with its plethora of fresh and frozen ocean fare. Still, even the most devoted fish fans want to see something new from time to time, and Costco manages to keep its choices from getting stale with brand-new offerings every year.

Granted, the membership warehouse has whiffed on some seafood items in the past, and a few seafood options are not worth buying at Costco. But these new additions in 2026 have been generally well-received, and the fact that they are still available indicates folks are still lining up to buy them. Judging from some customer comments on these products, that won't change anytime soon. Whether you stop by in person or have them delivered to your door, these fresh catches are worth considering for your next meal if you've ended up in a seafood rut. Prices vary regionally, so use the prices listed below as a guideline for roughly how much these premium eats will set you back.

Say goodbye to disappointing lunches with this trio of flavorful poke bowls that take only minutes to prepare.

Just thaw the tuna and mix in the sauce pack for instant seafood gratification. If you're feeling ambitious, this 12-pack of poke bowl kits would be perfect for tuna nachos, tacos, or sushi rolls.

Although they're begging to be the star of a crunchy taco, the fish fillets would work equally well in a tasty wrap or paired with spicy chipotle slaw for a quick dinner.
