With concerns over climate change globally, you might think that the last thing that environmentalists would worry about would be the natural food chain of wildlife; but for the Great Lakes there could be severe consequences posed if the carp manage to enter waterways they’ve been barred from entering.

Bighead carp are one of two non-native species of Asian carp causing widespread concern among Great Lakes advocates. The other is silver carp.

Great Lakes advocates are calling it a “conservation emergency” now that non-native Asian carp have been detected within seven miles of Lake Michigan. They want an immediate closure of locks and gateways leading to the lake in a literally”last-ditch” attempt to keep the fish out.

The fear is that the giant fish will disrupt the valuable Great Lakes sport fishery by outcompeting species at the top of the Lake Michigan food web, consuming the forage fish the established species depend on — and like many of the other 180 non-native aquatic species already in the Great Lakes, causing general ecosystem disruption.

A new report, The Economics of Ecosystems and Biodiversity (TEEB), attempts to bring to the world’s attention the truly great economic value of ecosystems and biodiversity, as well as the benefits of taking these into account when making policies.

The value of the world’s natural ecosystems and biodiversity is something lacking in most economic analyses. Lack of value for what is truly priceless doesn’t just hurt the environment, however. It is also a sort of economic suicide. This new report, hosted by the United Nations Environment Programme and supported by key EU, UK, German, Swedish, Dutch, and Norwegian bodies, attempts to bring all of this to our attention more and show some positive case studies of how taking the environment into consideration can actually save us money.

As the report says: “the failure of markets to adequately consider the value of ecosystem services is of concern not only to environment, development and climate change ministries but also to finance, economics and business ministries.”

Croatia and Hungary signed an agreement yesterday to protect a major biodiversity area that crosses borders along three rivers. The agreement is being called a “Trans-Boundary UNESCO Biosphere Reserve” and has resulted in the World Wildlife Fund (WWF) awarding the two countries with a “Leaders for a Living Planet” award.

The reserve will preserve several endangered species, among other environmental jewels. There is also the possibility of the reserve expanding several times over into neighboring countries in the future.

PacRim Coal’s plan to strip mine coal right through 11 miles of salmon-bearing streams in Alaska would destroy critical wetlands and headwater streams beyond the point of restoration, according to three new studies by scientists.

The salmon fisheries along the Chuit River would be severely damaged, so much so that the researchers say that restoration would be “virtually impossible”.

In a move praised by environmentalists fighting to protect vulnerable species, thousands of restaurants across the UK and Ireland have taken 69 fish off their menus.

The Compass Group, world’s largest contract caterer, is setting an example in addressing fisheries’ sustainability and helping to reduce demand for over-exploited fish. According to today’s Guardian, the 69 species on the Marine Conservation Society’s (MCS) “Fish to Avoid” list will no longer be served at 6,500 outlets across the UK and Ireland supplied by Compass.

Head of conservation at MCS, Simon Brockington, in the same article, praised the company’s decision, calling it a “crucial step in ensuring the long-term survival of vulnerable fisheries.”

Currently, a decision on whether or not to offer “official advice” to consumers on eating ethically is under consideration by the government’s Food Standards Agency. If the agency moves forward with the decision, it will encourage consumers not to buy or eat endangered fish,as well as direct them to the MCS and the Marine Stewardship Council (MSC).

Biologists have known for years that the low numbers of Southern Resident Killer Whales in Puget Sound may be tied to vessel traffic. A new plan for curbing vessel activity may help increase the population of these marine mammals.

New rules regarding vessel traffic have been proposed by NOAA’s Fisheries Service to provide additional protection of the Southern Resident Killer Whales (Orcinus orca). The regulations, if adopted, would take effect as early as May 2010.

According to today’s release by NOAA, the new proposal would curb vessel activity by:

• Prohibiting vessels from approaching any killer whale closer than 200 yards
• Forbidding vessels from intercepting or parking in the path of a whale
• Establishing a half-mile-wide no-go zone along the west side of San Juan Island from May 1 through the end of September, where generally no vessels would be allowed

17 dams recently built on the Mekong River in Southeast Asia are threatening fisheries, destroying a vast ecosystem, and starving millions. And 11 more dams are currently in the planning process.

The dams already in place are blocking fish from traveling upstream to spawn, and the new dams– many of which will sit nearer the river’s headwaters– could threaten the entire river ecosystem. 65 million people currently live and rely upon the Mekong for their sustenance and livelihood, and about 80 percent of their protein intake comes from the river’s fisheries.

Ever stare at the seafood counter and wonder where all that fish comes from? Maybe not, but I do, and a new article in Martha Stewart’s Body+Soul magazine wades through some other issues that might be on your mind - overfishing, fish farming, omega-3s and mercury.

Although the article sugar coats a few things (e.g. wild fish generally being a safe, sustainable option - not true), it contains some good advice. First and foremost, get to know the people that sell you fish. They can be your best ally in making good choices and are often a wealth of knowledge.

Second, don’t be afraid to ask questions like, ‘Where is this fish from?’, ‘Is it farmed or wild?’, etc. This will help steer you in the right direction.

Nine shark attack survivors will lobby the Senate to put new restrictions on fishing for sharks. The current legislation, Shark Fisheries Management Plan, implemented in the late 1990s, and the Shark Finning Prohibition Act of 2000 has failed to prevent thirty-two percent of the sharks and rays that live in the open ocean from being classified as “threatened” this year by the International Union for the Conservation of Nature.

The remarkable recovery of the Atlantic haddock (Melanogrammus aeglefinus), a commercial fish species once in serious decline from over fishing, is described with reference to an article in The Scientist (July 1, 2009) and a discussion of the theorized causes for this fish species’ rebound. Quote from the post:

The decline of commercially valuable ground fish stocks is symptomatic of the global, over-fishing crisis. Perhaps no other region on the globe is more indicative of this crisis than New England [...]
