Some Real Data - More to be thankful for....
A new study from the University of Plymouth's School of Biological and Marine Sciences (in the UK) has found that aquaculture can actually improve the area and associated species - just what Marsden has observed at his scallop farms. Lobstermen have told him that they feel the lobsters are benefiting from his sites.
Here are some quotes from the study:
"A new study from the University of Plymouth suggests that, in addition to helping meet global fish consumption demands, offshore aquaculture farms could potentially benefit the wider marine environment.
The study, recently published in the Aquaculture, Fish and Fisheries, was led by a team of researchers and Ph.D. candidates from the University of Plymouth’s School of Biological and Marine Sciences. The research is among the first to explore the environmental impact of offshore mussel farms and focused on Lyme Bay, which is located off the south coast of England and is the largest one in Europe...."
"There were also marked increases in the number of European lobster (Homarus gammarus) and edible crab (Cancer pagurus), both species that are commercially important in Lyme Bay but were not expected to be found in this area as it is highly degraded from years of bottom towed fishing.
“Over the past 15 years, we have consistently shown that a ban on bottom-towed fishing has had positive effects on the environment,” said Dr. Emma Sheehan, project lead and the study’s senior author. “This study has given us the first ecological evidence that offshore mussel farming can deliver similar benefits on degraded seabed habitats.”
And here is the whole study:
