MAINE: As gulf waters warm, could quahogs be the next big shellfish product?

August 20, 2021 — A new research project is trying to determine whether a species of hard-shell clam, quahogs, can thrive in enough abundance off Maine’s coast to make for a new business opportunity.

The Brunswick office of Manomet, an environmental research nonprofit headquartered in Plymouth, Mass., is partnering with the University of Maine and the Bigelow Laboratory for Ocean Sciences in East Boothbay to study the presence of quahog DNA in the water column.

Determining the level of DNA is considered useful to understanding to what extent the clams are making themselves at home in the gulf.

The study of DNA in this context is called “eDNA” or “environmental DNA,” Marissa McMahan, a senior fisheries scientist with the Brunswick branch of Manomet, told Mainebiz.

Robotic Floats Provide New Look at Ocean Health and Global Carbon Cycle

August 18, 2021 — Microscopic marine life plays a fundamental role in the health of the ocean and, ultimately, the planet. Just like plants on land, tiny phytoplankton use photosynthesis to consume carbon dioxide and convert it into organic matter and oxygen. This biological transformation is known as marine primary productivity.

In a new study in Nature Geoscience this week, MBARI Senior Scientist Ken Johnson and former MBARI postdoctoral fellow Mariana Bif demonstrated how a fleet of robotic floats could revolutionize our understanding of primary productivity in the ocean on a global scale.

Data collected by these floats will allow scientists to more accurately estimate how carbon flows from the atmosphere to the ocean and shed new light on the global carbon cycle. Changes in phytoplankton productivity can have profound consequences, like affecting the ocean’s ability to store carbon and altering ocean food webs. In the face of a changing climate, understanding the ocean’s role in taking carbon out of the atmosphere and storing it for long periods of time is imperative.

“Based on imperfect computer models, we’ve predicted primary production by marine phytoplankton will decrease in a warmer ocean, but we didn’t have a way to make global-scale measurements to verify models. Now we do,” said MBARI Senior Scientist Ken Johnson.

By converting carbon dioxide into organic matter, phytoplankton not only support oceanic food webs, they are the first step in the ocean’s biological carbon pump.

Phytoplankton consume carbon dioxide from the atmosphere and use it to build their bodies. Marine organisms eat those phytoplankton, die, and then sink to the deep seafloor. This organic carbon is gradually respired by bacteria into carbon dioxide. Since a lot of this happens at great depths, carbon is kept away from the atmosphere for long periods of time. This process sequesters carbon in deep-sea water masses and sediments and is a crucial component in modeling Earth’s climate now and in the future.

Fish councils prepare for climate change

August 16, 2021 — The New England Fishery Management Council is joining other East Coast marine management councils to plan for a future marked by the continuing detrimental impacts of climate change.

The project, called East Coast Climate Change Scenario Planning, is a response to the accelerating and debilitating impacts on fish stocks and marine habitats caused by the effects of climate change.

“No one knows for sure what the future holds, but a continuation or acceleration of climate change has the potential to strain our existing fishery management system and alter the way fishermen, scientists, and the public interact with the marine environment,” the NFMC stated. “Scenario planning is a way of exploring how fishery management may need to evolve over the next few decades as climate change becomes a bigger issue.”

The other organizations participating in the initiative are the Mid-Atlantic Fishery Management Council, the Atlantic States Marine Fisheries Commission, NOAA Fisheries’ Gloucester-based Greater Atlantic Regional Fisheries Office, the Northeast Fisheries Science Center and the South Atlantic Fishery Management Council.

The Northeast Regional Coordinating Council, which consists of leadership from the MAFMC, NEFMC, ASMFC, GARFO, and NEFSC, will be the primary decision-making body for the initiative, with the addition of South Atlantic representatives.

Record Salmon in One Place. Barely Any in Another. Alarm All Around.

August 16, 2021 — This summer, fishers in the world’s largest wild salmon habitat pulled a record-breaking 65 million sockeye salmon from Alaska’s Bristol Bay, beating the 2018 record by more than three million fish.

But on the Yukon River, about 500 miles to the north, salmon were alarmingly absent. This summer’s chum run was the lowest on record, with only 153,000 fish counted in the river at the Pilot Station sonar — a stark contrast to the 1.7 million chum running in year’s past. The king salmon runs were also critically low this summer — the third lowest on record. The Yukon’s fall run is also shaping up to be sparse.

The disparity between the fisheries is concerning — a possible bellwether for the chaotic consequences of climate change; competition between wild and hatchery fish; and commercial fishing bycatch.

“This is something we’ve never seen before,” said Sabrina Garcia, a research biologist with the Alaska Department of Fish and Game. “I think that we’re starting to see changes due to climate change, and I think that we’re going to continue to see more changes, but we need more years of data.”

The low runs have had ripple effects for communities along the Yukon River and its tributaries — the Andreafski, Innoko, Anvik, Porcupine, Tanana and Koyukuk Rivers — resulting in a devastating blow to the people relying on salmon as a food staple, as feed for sled dogs and as an integral and enriching cultural tradition spanning millenniums.

Climate Change Scenario Planning: Input Needed to Prepare for an Era of Uncertainty in Ocean Conditions and Fisheries

August 11, 2021 — The following was released by the New England Fishery Management Council:

On the East Coast of the U.S., some species of fish are already experiencing climate-related shifts in distribution, abundance, and productivity. No one knows for sure what the future holds, but a continuation or acceleration of climate change has the potential to strain our existing fishery management system and alter the way fishermen, scientists, and the public interact with the marine environment.

In order to begin preparing for this new era of uncertainty, management bodies along the entire Atlantic seaboard have teamed up to launch a project called East Coast Climate Change Scenario Planning. Scenario planning is a way of exploring how fishery management may need to evolve over the next few decades as climate change becomes a bigger issue. Here is the introductory brochure.

Climate change ‘double whammy’ could kill off fish species

August 10, 2021 — New research suggests that fish like sardines, pilchards and herring will struggle to keep pace with accelerating climate change as warmer waters reduce their size, and therefore their ability to relocate to more suitable environments.

The study, published in Nature Climate Change, also provides the first evidence to counter the scientific theory that decreased movement will result in more species, by suggesting the opposite is true. This means many species will also be less able to evolve to cope with warmer temperatures, increasing their risk of dying out.

Professor Chris Venditti, an evolutionary biologist at the University of Reading, and co-author of the study, said: “Warming waters are a double whammy for fish, as they not only cause them to evolve to a smaller size, but also reduce their ability to move to more suitable environments.

“Our research supports the theory that fish will get smaller as oceans warm under climate change, but reveals the worrying news that they will also not be able to evolve to cope as efficiently as first thought. With sea temperatures rising faster than ever, fish will very quickly get left behind in evolutionary terms and struggle to survive.

“This has serious implications for all fish and our food security, as many of the species we eat could become increasingly scarce or even non-existent in decades to come.”

The study, led by the Center for Advanced Studies in Arid Zones (CEAZA) in Chile and the University of Reading in the UK, used statistical analyses of a large dataset of globally distributed fish species to study their evolution over the past 150 million years. The study provides first solid evidence of how historical global temperature fluctuations have affected the evolution of these species.

It focused on Clupeiforms — a highly diverse group of fish found all over the world, which includes important species for fisheries, such as anchovies, Atlantic herring, Japanese pilchard, Pacific herring, and South American pilchard. However, the findings have implications for all fish.

Fish have thus far only had to deal with a maximum average ocean temperature rise of around 0.8°C per millennium. This is far lower than current warming rates reported by the National Oceanic and Atmospheric Administration of 0.18°C per decade since 1981.

Gulf of Mexico ‘dead zone’ has grown larger than Connecticut

August 9, 2021 — A “dead zone,” or an area of low to no oxygen, in the Gulf of Mexico has grown larger than Connecticut, creating an uninhabitable environment for some commercial marine life, and scientists are saying the sparse amount of tropical activity has played a role.

An hypoxic zone, also referred to as a dead zone, is formed when excess nutrients such as nitrogen and phosphorus from agriculture and sewage from cities and farms upstream wash into the Gulf. Algae then feeds on these nutrients during the warmer months, and when that algae dies and sinks to the Gulf’s floor, the bacteria that then eats away at the large tangled masses depletes the oxygen in the surrounding water.

The resulting area of low oxygen is called a hypoxic zone, or a dead zone as it becomes unable to support marine life, and it forms in the Gulf every year. Not only can it harm local wildlife, but it can also financially impact fisheries.

Hypoxic waters have been found to alter fish diets, growth rates, reproduction, habitat use and availability of commercially harvested species such as shrimp, according to the National Oceanic and Atmospheric Administration (NOAA).

Now, fisheries along the coast of Louisiana will have to deal with a larger-than-average dead zone.

“Basically half of the Louisiana coast for several miles, many miles off shore, the oxygen was too low to support the occurrence of penaeid shrimp, which is one of our biggest economic fisheries in that area,” Dr. Nancy Rabalais, professor at Louisiana State University and LUMCON, and also the principal investigator, told AccuWeather. “So that area was basically lost as available and suitable habitat to those shrimp. How that’s going to convert to catches in money in the next month or so, I can’t really say.”
