US sales of plant-based frozen seafood alternatives hit $11.5 million (€10.6 million) in 2022, up 17.1 percent from 2021, according to data from IRI Integrated Fresh and supplied by market research firm 210 Analytics.

Despite the double-digit dollar sales rise, both the number of units sold and the volume sold in 2022 grew at a noticeably slower pace.

"The dollar performance was far better than the unit and volume performance, which means inflation played a role," said Anne-Marie Roerink, CEO of 210 Analytics.
