The fresh fish offering from 3663 has been expanded from 44 lines to 350 in response to increasing consumer demand.
It now provides 60 species of fresh fish and says it can provide every major cut in its range of fresh seafood.
Vanessa Millard, marketing manager at 3663, said: “Fish is a popular menu choice and one that’s soared in favour over recent years. The total foodservice market for fish is worth pound;584m a year, and there has been a 7.5% increase in consumption since this time last year.
From the middle of this month 3663 will be able to deliver fresh fish along with regular food orders, and it can offer next day delivery for orders placed before 4pm.
