Value sales of shellfish have risen 4.7% year-on-year to £191.5m [Kantar 52 w/e 21 February]. Although volumes are static at 20.6 million kg, usage occasions have increased 2.7% .
As the credit crunch hit, there was a trend for shellfish to be eaten more in the home and less in lunchboxes, said Kantar analyst Michael Vahid.
The evening meal now represents 70% of consumption, up 5% year-on-year, with lunchbox usage falling 31% to 3.7%.
People were starting to understand that shellfish was healthy and not high in cholesterol, said Shellfish Association of Great Britain director Tom Pickerell, adding that the association had 40,000 hits on YouTube for its How To cooking videos.
"Shellfish is low-fat, low-calorie and very filling," he added.
