‘We’re Facing a Double Whammy’: America’s Hottest Tinned Fish Snack Is Shrinking by Nearly Half Thanks to Climate Change and War in Iran

Tinned fish is having a real global moment. The pandemic-era pantry habit has since turned into restaurants nationwide serving tinned fish straight out of the can. Domestically, sales climbed from $2.3 billion in 2018 to more than $2.7 billion in 2024, and the U.S.’s obsession with sardines specifically is only accelerating: Americans bought $3.52 billion worth of shelf-stable seafood over the past year, and sardines have overtaken salmon as the second-most-popular canned fish behind tuna, as Grubhub reported orders of tinned fish tripled in 2025. The global tinned fish market was worth roughly $10.24 billion in 2024 and is projected to reach $17.97 billion by 2034. Canned sardines are a meaningful part of that worldwide push.
