The Cumbria Wildlife Trust has accused the Government of failing to protect and recover the regions most at-risk wildlife and habitats.
The Trust has argued that postponing plans to create a network of "nature reserves" off the coast of Cumbria will leave the Irish Sea open to an environmental disaster.
Two years ago, five areas off of the Cumbrian coast were put forward as potential Marine Conservation Zones, which would restrict fishing and human activity.
Three, including Mud Hole near Whitehaven, have since been declared unsuitable.
Two more, Allonby Bay in northwest Cumbria and West of Walney a few miles out to sea from Barrow, will go up for consultation this year.
The Trust argues that the reserves would not only protect at-risk wildlife, but improve the fishing industry.
"Supporting sustainable fisheries, instead of encouraging overfishing and habitat destruction, would increase fish landings, generate more income and create more jobs in the sector.
Decision-makers need to think of sustainable fisheries as an opportunity for job creation and increasing the value of fisheries rather than an environmental principal that comes at a price to the industry. MCZs are a vital part of this process."
