'Fish sludge' from Mowi-owned Northern Harvest's salmon die-off raises environmental concerns

The thick layer of sludge is now sitting at the bottom of Fortune Bay, according to a marine conservationist who observed the cleanup.

As many as 1.8 million farmed fish from Mowi-owned Northern Harvest Sea Farms in Newfoundland may have died, reported The Globe and Mail.

The die-off, according to Northern Harvest, was due to prolonged high water temperatures at some sea sites on the south coast of Newfoundland. Workers are still processing the decomposing waste, as they have been for weeks, producing a pink fish sludge, processed on land then dumped back at sea.

Fisheries unions have stated their concern over the impact of the fish sludge.

The layer of sludge now sitting at the bottom of Fortune Bay is more than 15 meters thick, according to a marine conservationist who observed the cleanup.

Ryan Cleary, current president of the Federation of Independent Seafood Harvesters, is calling for widespread reforms to Newfoundland's aquaculture industry.
