Marr, Italy's largest foodservice marketer and distributor with €1.25 billion ($1.6 billion) in revenues in 2011, said it predicts a 'tricky situation' for the country's seafood business.

Increasing fuel costs and stiff competition for seafood supplies from emerging markets such as China, India and Thailand make it hard to predict the future of Marr's seafood division, said the company's investor relations representative Antonio Tiso.

Seafood sales are a key part of Marr, accounting for a third of its revenues in 2011.

"The seafood division is an important part of Marr's business," Tiso told IntraFish.
