Study: Genetically modified salmon can breed with wild fish
|
JUNEAU - July 18, 2011 -- A new study of genetically modified salmon shows they can breed with their wild counterparts.
That raises concerns that escaped farmed fish could weaken wild stocks. It’s not an immediate threat to Alaska species, though it could be to commercial sales.

Woods Hole Study: Changes to ocean expected to damage shellfish around world
|
|
July 18, 2011 (CNN) -- Massive global greenhouse gas pollution is changing the chemistry of the world's oceans so much that scientists now predict it could severely damage shellfish populations and the nations that depend on the harvests if significant action isn't taken.
A new study from the Woods Hole Oceanographic Institution in Massachusetts shows that ocean acidification is becoming a very serious problem. The study was published in July online in the journal Fish and Fisheries.
"What the study found was that in the next 10 to 50 years many countries are going to see impacts, particularly countries that are heavily reliant on clams and oysters and mussels, and will not be able to adapt by shifting to other foods or aquaculture methods," said Jackie Savitz, senior scientist and chief strategist for the international ocean conservation and advocacy organization Oceana.

Fishy Science on the Great Barrier Reef

Writing in Quadrant magazine, the Australian journal of ideas, literature, poetry and historical and political debate, Dr.Walter Starck observes that before "the ascendancy of environmentalism, the scientific ideal was an objective, evidence-based, value-neutral search for truth. Basic research, aimed only at better understanding the world in which we live, was pursued with considerable success. Over recent decades, however, basic research in natural history has been largely supplanted by studies predicated on environmental concerns. As a consequence, acquisition of new understanding of the nature and functioning of the natural world has declined. In addition, much of the research into purported environmental problems suffers from bias and distortion arising from adherence to faith-based notions of environmental correctness." Dr. Starck holds a PhD in marine science from the Institute of Marine Science at the University of Miami. He was a pioneer in the study of coral reef biology and the development of undersea technology.
