Comprehensive global study confirms restorative aquaculture has positive impacts on marine life

June 25, 2021 — The following was released by the University of New England:

The University of New England partnered with The Nature Conservancy (TNC), the world’s leading conservation organization, on a ground-breaking new study that provides strong evidence that shellfish and seaweed farming are a critical component of regenerative food production.

The comprehensive study has been published in Reviews in Aquaculture at a time when much news of food production focuses on its negative impacts on the environment. Quite to the contrary, the study, titled “Habitat value of bivalve shellfish and seaweed aquaculture for fish and invertebrates: Pathways, synthesis, and next steps,” paints a bright picture of aquaculture’s potential to help satisfy food demand in harmony with ocean health.

Restorative shellfish and seaweed farming offers a sustainable method to meet the nutritional needs of the growing human population, while maintaining and improving the health of the waters, lands, and animals we live alongside. This study is among the first to demonstrate the global potential for regenerative outcomes in aquaculture systems.

“Aquaculture is among the world’s fastest-growing forms of food production and there is a growing biodiversity crisis that already exists in our ocean. It’s critical that we identify ways to develop aquaculture that benefits, rather than harms our ocean, that are based on sound science,” said Robert Jones, Global Lead for Aquaculture at The Nature Conservancy. “This study is game changing in that it clearly shows an opportunity through shellfish and seaweed aquaculture. For the first time, we’re able to put quantifiable global numbers on the benefits these farms can have on marine wildlife.”

New Online Course for Spotting and Reporting Entangled Whales in Alaska Waters

October 3, 2019 — The following was released by NOAA Fisheries:

The foundation of responding to entangled whales is the on-water community. NOAA’s Alaska Marine Mammal Stranding Network depends on recreational and commercial boaters and other ocean users for spotting and reporting entangled whales off Alaska’s coast. That’s one reason NOAA Fisheries has teamed up with The Nature Conservancy (TNC) to develop a new online training course to help them report entanglements.

Most often, fishermen, tour boat operators, and whale researchers are the ones to first report entanglements. The course will prepare them, and others, to report entanglements in Alaska.

Responding to whale entanglements can be dangerous. Only highly trained and experienced teams with the proper equipment should attempt to disentangle whales.

Boaters who come across entangled whales can still help in the response without getting too close. They can collect information and monitor the whale until trained teams arrive. By knowing what information to collect, and taking and sharing photos with the disentanglement team, boaters can help marine mammal responders. These teams have advanced training to understand the extent of the entanglement before mounting a response. This enables them to respond with the right gear.

“Fishermen and other boaters are our eyes on the water,” said Jon Kurland, head of the NOAA Fisheries Alaska Region Protected Resources Division. “Countless times the information they have provided about a whale entanglement has been the key factor in our response network’s ability to locate the animal, assess its condition, and attempt to disentangle it if the conditions are right.”

Blue Planet: The Nature Conservancy unveils $1.6 billion bid to save the oceans

April 17, 2019 — Global non-profit The Nature Conservancy has announced a $1.6 billion plan to help save and restore the world’s oceans by selling “blue bonds” to coastal and island countries.

The Blue Bonds for Conservation initiative will refinance and restructure debt for coastal and island countries, so long as those nations committed to protecting at least 30 percent of their near-shore ocean areas, including coral reefs, mangroves, and other important ocean habitats.

In exchange for enhanced ocean protections, TNC says the Blue Bond will give nations better terms for debt repayment and support with ongoing conservation work.

Gulf of Mexico Oysters are in Trouble, but There’s Hope and a Plan

November 28, 2018 — Oysters in the Gulf of Mexico have seen better days.

Aside from the Deepwater Horizon explosion and oil spill in 2010 — which killed between 4 and 8.3 billion adult oysters, according to NOAA — changes in freshwater flow along the Gulf and sedimentation caused by more frequent storms have taken their toll on the Gulf’s oyster population.

But all hope is not lost. In fact, there’s even a plan, according to a report by environmental organization The Nature Conservancy (TNC).

Compared to historic levels, an estimated 85 percent of the Gulf’s oyster population has been lost, and the impact ranges further than the $100-million-per-year market they provide.

Oyster beds in the Gulf are vital in improving water quality, providing protection from shoreline erosion and serving as a habitat for fish and wildlife.

The impact of waves, boat wakes and storm surge on the Gulf’s shoreline is reduced by oyster reefs. Reefs are also unique in that they can continue to grow to keep up with or even outpace sea level rise, according to an entry in the journal Nature, something hard sea walls can’t do.

Additionally, a single oyster can filter 50 gallons of water in one day. In places like Galveston Bay, a 130-acre reef containing 10 oysters per square meter would be capable of filtering about 260 million gallons of water each day. In comparison, Houston’s 39 wastewater treatment plants combined to filter 252 million gallons per day in 2009, according to Texas Parks and Wildlife.

Gulf Coast Looks to Maintain, Restore Oysters

November 26, 2018 — The oyster dressing is safe this year.

Since the Deepwater Horizon spill in 2010, 4 billion to 8.3 billion subtidal oysters were estimated to be lost across the Gulf coast. Many states are struggling.

Louisiana is the only state producing at a level at or higher than before the spill, according to Seth Blitch, The Nature Conservancy’s Director of Coastal and Marine Conservation in Louisiana.

“Oysters Gulfwide are kind of in a bad spot, but Louisiana is actually sort of the bright spot in terms of commercial production of oysters. Louisiana produces more oysters than any other state in the country, which is good,” Blitch said.

TNC recently released a report on oyster restoration in the Gulf.

According to the report, there’s been about a 50 percent to 85 percent oyster loss throughout the Gulf when compared to historic levels.

The oyster industry pulls about $220 million to Texas, Louisiana, Mississippi, Alabama and Florida. The decrease could affect not only oyster harvesters but restaurants and industries that use the shell, such as using it to supplement chicken feed.
