The highest growth items included tuna (59 percent), shellfish (47 percent) and octopus (28 percent), according to data from the Vietnam Association of Seafood Exporters and Producers.
Japan and France were the top markets for crabs, accounting for 91 percent of exports.
Exports to the U.S. also recovered as the country reopened after Covid-19.
Insiders said growth was driven by global demand and the Russia-Ukraine conflict.
But high costs affected production and supply, they said, adding that a shortage of raw material was the biggest challenge for exporters.
