Report: Climate change threatens food fish in Northeast

We continue to witness fall out from environmental changes brought on by our collective failure to better use and protect our natural capitol.  Today, we threaten, with over development, many fragile eco-systems.  Yet, today we also are turning the destructive ship around and remediating our damage.

Seafood is a wonderful staple of our food supply and quality of life here in the Northeast.  As stated below we can better protect our oceans and rivers.  Our quest to bring the ecological system back in balance around a robust but clean green economy is the paramount issue of our generation and all future generations.



PORTLAND, Maine (AP) — Fish and shellfish that humans rely on for food and that are important to the economy are on a list of Northeastern marine species considered most vulnerable to climate change, a federal government report released Wednesday and published by the journal PLOS ONE said.

The study ranged from Cape Hatteras, North Carolina, to the Gulf of Maine and is the first "multispecies assessment" of the vulnerability of marine fish and invertebrates to climate change, the National Oceanic and Atmospheric Administration said. A series of similar assessments will follow in other regions of the U.S.

NOAA's report assigned a "climate vulnerability score" to 82 Northeastern fish and shellfish species. It listed types of scallop and quahog and the Atlantic salmon as the most vulnerable in the region, as well as eastern oysters, a $175 million fishery in 2014. Also, certain types of herring, a vital part of the ocean's food web and commercially important as bait, were found to be highly vulnerable to climate change.

Lead author Jon Hare, a NOAA oceanographer based in Rhode Island, said scientists found that most of the species they studied will be affected by climate change in some way.

In addition, Hare said, "Those effects are going to continue into the future. We've seen impacts in the past, but this study provides support for the idea that those changes are going to continue."

The 82 species represent every commercially managed marine fish and invertebrate species in the Northeast; the list also includes some popular recreational marine fish and all marine fish listed or under consideration for protection under the Endangered Species Act.

Changing ocean conditions impact marine animals' reproduction, predation and ability to grow. Hare said researchers studied how vulnerable the species are to changes in the ocean's temperature, acidity, salinity and other features.

Also among their findings were:

—About half of the 82 species studied are either highly vulnerable or very highly vulnerable to climate change. About half will likely be negatively affected by climate change and 20 percent will be positively affected by it. The impact on others appears to be neutral, Hare said.

—Some already challenged species such as winter flounder are at risk. Winter flounder have declined from a 15.3 million pound fishery in 2001 to 4.4 million pounds in 2015.

Peter Baker, director of Northeast U.S. oceans for the Pew Charitable Trusts, said the report should be a motivator for fishing managers to protect more ocean habitat and preserve marine species.


"We can better protect the ocean habitat where fish find food and shelter and reproduce," he said.
