"While a genetically engineered salmon is almost certainly safe to eat, the government should pursue a more rigorous analysis of the fish's possible health effects and environmental impact, members of a federal advisory committee said yesterday."

"The first genetically modified animal could move one step closer to the U.S. market on Monday, when a federal advisory panel makes its recommendation on whether such food -- a salmon -- is safe for consumers to eat."

"Decades of overfishing have deprived the food industry of billions of dollars in revenue and the world of fish that could have helped feed undernourished countries, according to a series of studies released on Tuesday."

"The federal government declared in April that basking sharks in the Pacific Ocean are a 'species of concern,' which means the government doesn't yet have enough information to say the giant fish is threatened or endangered, but it might be."

The Atlantic bluefin tuna, one of the wildest of wild fish, is in decline. Paradoxically, aquaculture scientists say a recent breakthrough in captive breeding of the fish may help save it.

"The world should safeguard coral reefs with networks of small no-fishing zones to confront threats such as climate change, and shift from favoring single, big protected areas, a U.N. study showed."

"Oxygen levels fell significantly in deep-sea areas of the Gulf of Mexico contaminated by oil plumes from the BP spill. But although researchers found a 20% decline in dissolved oxygen, the drop was not steep enough to create biological 'dead zones' that some scientists feared might form in the wake of the BP disaster." Those were the findings of a government study.

"U.S. health officials are set to rule on whether a faster-growing, genetically engineered fish is safe to eat in a decision that could deliver the first altered animal food to consumers' dinner plates."

"After years of declining sockeye numbers and a struggling fishing industry, the Pacific Salmon Commission last week said it now expects 25 million sockeye will return to the Fraser River this year -- more than double its earlier forecast and the best run since 1913."

"Chesapeake oysters are a succulent treat that for centuries have been loved almost to extinction.  But some scientists and business people are making headway in bringing back the bivalve, for the sake of oyster lovers and the bay."
