West Coast Species on the Move as Climate Change Drives Ecological Shifts, Analysis Shows

February 22, 2023 — The following was release by NOAA Fisheries:

All but the most resilient marine species off the West Coast are likely to be vulnerable to climate change, according to a new NOAA Fisheries assessment. It will help inform fisheries management and species protections as the climate changes in the coming decades.

The assessment found that nearly all commercial fish stocks overseen by the Pacific Fisheries Management Council are vulnerable to climate change. Species with complex life histories, long life spans, or of high commercial value are the most vulnerable to the effects of climate change in the California Current.

“We are looking forward, and we see that changes in these species may be the rule rather than the exception,” said Michelle McClure, lead author of the assessment who did much of the work while at the Northwest Fisheries Science Center in Seattle. “The goal is to anticipate the changes and make more climate-informed management decisions, and this assessment should help.”

Scientists are currently documenting the shift of marine species north or into deeper, cooler waters, as they follow their preferable temperatures. Such shifts are likely to become more widespread as climate change continues. Depressed oxygen levels, known as hypoxia, may also become more common and take a toll on bottom-dwelling species. These species cannot move very far or fast to avoid these low-oxygen areas.

Fishermen and Scientists Partner to Fill Critical Data Needs for Bristol Bay Red King Crab

February 22, 2023 — The following was released by NOAA Fisheries:

Tempestuous weather and icy seas make winter research on Bristol Bay red king crab challenging. This winter, crab fishermen are working together with scientists to make it possible.

The Bering Sea crab industry is partnering with NOAA Fisheries’ Alaska Fisheries Science Center and the Alaska Department of Fish and Game to meet a critical need for winter data on Bristol Bay Red king crab. Scientists and fishermen will work together on the month-long field research, set to launch in March. The research responds directly to data requests from the North Pacific Fishery Management Council to inform their management decisions.

“It’s an exciting chance to study this stock in winter,” said study lead Mike LItzow, Alaska Fisheries Science Center. “That’s when people really interact with the stock— the Bristol Bay red king crab fishery and many other fisheries that potentially interact with crab take place in fall and winter. But because of the difficulty of working in the Bering Sea in winter, we don’t have great data then. This is a great opportunity to fill that data gap.”

NOAA releases draft of National Seafood Strategy document

February 17, 2023 — NOAA has released its draft National Seafood Strategy, which will outline how the administration supports the domestic U.S. seafood economy and seafood sector in the coming years.

The strategy, released 14 February, focuses on NOAA Fisheries’ work on managing the country’s marine fisheries “based on sound science.” It also addresses a number of other factors affecting the seafood industry, including the financial viability of the industry, the resilience of coastal communities that depend on fishing, the effects of international trade – and the opportunities it can present, and the importance of seafood as a source of nutrition and food security.

NOAA extends deadline for nations seeking to validate marine mammal bycatch criteria

February 17, 2023 — NOAA Fisheries extended the deadline to evaluate applications from nations seeking to prove their fishing practices meet U.S. standards for marine mammal bycatch.

Nations wishing to send wild-caught seafood products to the U.S. need a comparability finding for commercial fishing operations. Provisions contained within the Marine Mammal Protection Act (MMPA) require fisheries outside the U.S. to meet the U.S. standards on conserving marine mammals.

2 more whales found dead along Atlantic Coast. NOAA says they were likely hit by boats.

February 16, 2023 — Necropsies on two whales found dead along the Atlantic coast this week revealed that both marine mammals showed evidence of vessel strikes.

Both whales, a critically endangered North Atlantic right whale and a humpback, were already beginning to decompose, but preliminary results show internal injuries consistent with the blunt force trauma of a vessel strike, the National Oceanic and Atmospheric Administration said Tuesday.

The deaths are among a flurry of 21 whale deaths along the length of the Atlantic coast since Dec. 3.

While several politicians who previously expressed opposition to — or concerns about — offshore wind energy projects have called for a moratorium on wind activities and an investigation into the whale deaths, preliminary exams show at least five of the 21 whales were likely killed in vessel collisions. Several were too decomposed to be examined.

Third dead whale found miles from offshore wind farm in less than a week

February 15, 2023 — The third dead whale was discovered in less than a week off the southeastern coast of Virginia, miles from Coastal Virginia Offshore Wind (CVOW), one of two operational wind farms in federal waters.

Over the weekend, a critically endangered North Atlantic right whale was discovered washed ashore near Chic’s Beach which is located in Virginia Beach, Virginia, the National Oceanic and Atmospheric Administration (NOAA) confirmed to Fox News Digital on Monday. According to local news outlets, there was no immediate cause of death and the whale didn’t appear to have any entanglement marks.

The discovery of the beached right whale came just two days after a humpback whale was found dead along the shoreline in Cape Charles, Virginia, and five days after a dead humpback whale was found off the coast of First Landing State Park in Virginia Beach.

“There have been 3 large whale strandings in VA over the past week, two humpbacks and more recently a North Atlantic right whale,” NOAA spokesperson Allison Ferreira told Fox News Digital in an email. “We are investigating all of these incidents in collaboration with our stranding network partners.”

Public helps NOAA track turtles around Maui

February 14, 2023 — A turtle known as MA100 has commonly been seen around Kaanapali since 2021. Another known as MA101 is commonly seen around Kihei but was first sighted at Maalaea Bay in 2021.

They’re among the many honu that scientists have been able to track around Maui thanks to the help of citizen scientists who report sightings of the Hawaiian green sea turtles based on special etchings on their shell.

The data collected through the citizen science-driven Honu County project helps staff with the National Oceanic and Atmospheric Administration Fisheries better understand foraging habitats, migration, distribution and the survival status of particular honu across Hawaii.

NOAA recently launched a new online tool to make it easier for folks in the Maui community and statewide to report sightings.

Since the inception of the Honu Count in 2017, nearly 600 people reported 688 sightings of 253 individual turtles. It’s a way for the public to engage in sea turtle research and conservation, according to NOAA.

Wind energy gets scrutiny following whale deaths

February 10, 2023 — Politicians, citizens and some environmentalists are calling for a slow-down or complete halt of wind energy activity off the East Coast as officials examine the cause of a rash of marine animal deaths, but neither action nor an answer appears to be imminent.

In January, the debate landed on the shores of Worcester County with the body of a humpback whale, which immediately led to speculation regarding the cause of its death.

The National Oceanic and Atmospheric Administration is examining samples taken from the whale, but representative Allison Ferreira said that it will take “weeks to months” to receive the necropsy report.

“Given that necropsy reports provide a comprehensive account of the stranding event, ranging from a description of external observations and internal examination findings to the diagnostic results of samples taken, they can take several weeks to months to complete and finalize,” Ferreira said in an email.

A few days later, Ferreira added that preliminary findings from the necropsy indicate vessel strike as the cause of death.

“But we do not know (definitively) if it was struck before or after death,” she said. “Results from samples taken from the whale may help inform this, but we may never know.”

Zooplankton Research Reveals a Glimpse of the Potential Future Northern Bering Sea Ecosystem

February 10, 2023 — The following was released SeafoodSource:

From fish to whales, nearly every predator in the sea eats zooplankton, or eats something that does. Understanding how climate impacts zooplankton can help us predict ecosystem changes to build resilient, climate-ready fisheries and communities.

A new collaborative NOAA Fisheries study looked at northern Bering Sea zooplankton over 17 years (2002–2018) of both cold conditions and unprecedented heat. The research revealed that loss of sea ice resulted in dramatic shifts. Large, high-fat copepods that are important food for many predators dwindled, while small zooplankton expanded in both number and range. This altered prey field may have contributed to ecosystem-wide impacts on fish, seabirds, and marine mammals.

“Zooplankton are near the base of the marine food web. If the base changes, we will see changes higher in the foodweb. There will be species that respond better than others,” said study lead Dave Kimmel, NOAA Fisheries, Alaska Fisheries Science Center EcoFOCI program. “By studying zooplankton we can see what the future ecosystem might look like. That knowledge can help people who make a living on it, or manage it, adapt and prepare.”
