For years, environmentalists and watermen have been searching for a way to deal with the Chesapeake Bay's "ghost pots" — derelict crab traps that are too deep to retrieve and too problematic to co-exist with marine life. Though the traps have been abandoned, they continue to ensnare and kill crabs.
A study led by researcher Lisa Kellogg of the Virginia Institute of Marine Science shows that a restored oyster reef can remove up to 10 times more nitrogen from Chesapeake Bay waters than an unrestored area nearby, providing additional evidence that reef-restoration can contribute to efforts to improve water quality in the nation's largest estuary.
Transgenic Atlantic salmon, genetically modified to grow larger and faster than wild-type fish, are capable of hybridizing with wild brown trout, creating offspring that carry modified growth genes and outcompete both wild and GM fish, according to new research conducted by Canadian scientists. The modified salmon is poised to become the first GM animal approved for human consumption in the United States, with the US Food and Drug Administration approaching a decision on the product.
Plans for an experimental aquaculture operation near Mount Desert Island have some local residents up in arms. Supporters of the scheme to raise commercially-harvested clams and oysters see it as a way to stimulate the local economy, with minimal effects on the scenery or the environment. But some locals disagree. And, as Tom Porter reports, they also have questions regarding the partiality of the state when it comes to awarding aquaculture leases.
