Other ULT Frozen-Onboard Products Besides Tuna, we also use ULT temperatures to freeze other species onboard the fishing boat. Although these species don’t require ULT temperatures to retain sashimi quality, we know that the faster you freeze a product, the fresher it is. Freezing any fish at -76°F results in exceptional quality frozen seafood products. Swordfish |
