Paris, Thursday.

HUNDREDS of fishermen wielding clubs and firing flares ransacked the

wholesale Paris fish market and blockaded Calais with trawlers today to

demand protection from cheap fish imports.

Over 20 people were hurt as the protesters, infuriated by dwindling

income and disappointed by an emergency aid package, swept across

northern France, attacking supermarkets and throwing tons of fish into

the street.

To appease them before Prime Minister Edouard Balladur visits Brittany

tomorrow, the government ordered Customs officers to reinforce border

controls on fish imports.

The Calais harbour blockade disrupted ferry services to Britain, which

had protested to France earlier in the day about the destruction of a

consignment of British fish.

Police said about 600 fishermen from Brittany, centre of a widening

five-day-old fishing strike, descended on the Rungis market, south of

Paris, before dawn.

They burst through a police cordon and a teargas barrage, destroyed

some 60 tons of fish and overturned police cars.

Eighteen policemen were slightly injured during the hour-long clashes,

police said. Demonstrators said a fisherman suffered a fractured skull

and another was injured in the eye.

''We've got mouths to feed. Our jobs are at stake,'' one fisherman

told market workers who sought to stop him.

''We've got our own problems,' retorted an employee at the market,

which was hit by a similar protest last year. 'Nobody is earning gold

today. I've got no fish for my customers tomorrow.'

Officials said 10 trawlers began blockading Calais today and fishermen

also set up a roadblock at the ferry terminal, searching lorries

suspected of importing fish.

''We've had to divert ferries from Dover. Two ferries of the P&O

company have been sent to Zeebrugge. We've also got another P&O ferry

stranded in the port unable to get out,'' an official said.

Other demonstrators attacked two hypermarkets and a frozen food

warehouse in Calais and Boulogne. A fisherman was hurt in Boulogne as

riot police responded with volleys of teargas.

In Cherbourg, fishermen vandalised a Scottish trawler's cargo, pouring

fuel on 20 tons of mackerel, a harbour official said. They also

destroyed tons of imported and French fish in the Brittany town of

Plerin.
