ANALYSIS - The US Environmental Protection Agency (EPA) is using its Clean Water Act to try to prevent permanently mine waste from being disposed into Alaskas Bristol Bay watershed, home to the world's largest wild salmon fishery, writes Lucy Towers, TheFishSite Editor.

This decision puts on hold attempts to build the Pebble Mine, which would be North America’s largest open pit gold-copper mine.

The EPA’s action is not a final decision to block the mine. But while the review occurs as authorised by section 404c of the Clean Water Act, the US Army Corps cannot take any steps to grant permits.

“We're thrilled the EPA is taking this important step to protect the world's greatest wild salmon fishery, and the communities that depend on it,” said Earthworks executive director Jennifer Krill.

Sri Lanka has begun its first offshore aquaculture operations, according to the country's Daily Mail. Local company Oceanpick installed the first sea cage in China Bay, Trincomalee and now barramundi production is well under way.

Millions of scallops have died in Canada near Qualicum Beach, British Columbia, due to the increasing acidity of the ocean. More carbon dioxide produced from fossil-fuel burning operations is being absorbed by the ocean thereby increasing acidity levels of the water.

Since 2009, more than 10 million young scallops have died at the Island Scallops farm, reported CBC news.

The Danish government has unveiled a new aquaculture strategy with a focus on greener technologies for fish farm production and increased export of resource-efficient recirculation aquaculture systems (RAS).

Denmark has proved that it is able to increase production of fish while at the same time reducing the environmental impact. It is a success that must be shared both in Denmark and on export markets.
