(Bloomberg) --

French maritime minister Annick Girardin has called for an investigation into the alleged dumping this week of 100,000 dead fish off the country’s Atlantic Coast by a Dutch-owned trawler. 

The environmental activist group Sea Shepherd released footage showing the carpet of floating carcasses covering an estimated 3,000 square meters (32,300 square feet). 

The spill of blue whiting, a species used to produce fish fingers and other products and which is subject to quotas, was said to have been caused by a break early Thursday in one of the the trawler’s nets. The industry group that represents the vessel’s owner reported it as a “fishing incident.” 

Campaigners with Sea Shepherd France, though, disputed what the Pelagic Freezer-Trawler Association called a “very rare occurrence.” 

The environmentalists said it appeared the fish had been dumped in a bid by the vessel’s operators to discharge a type of catch it didn’t want to process, a practice banned under EU rules. 

Virginijus Sinkevicius, the European Union Commissioner for environment, oceans and fisheries, echoed France in calling for an “exhaustive” inquiry.
