Protecting Coastal Blue Carbon through Habitat Conservation

February 8, 2021 — The following was released by NOAA Fisheries:

Coastal habitats like salt marshes, mangroves, and seagrass beds provide us with countless benefits, from nursery grounds for fish to protection from storms. They also play an important role in addressing climate change by removing greenhouse gases like carbon dioxide from the atmosphere and storing them. The NOAA Fisheries’ Office of Habitat Conservation works to protect and restore these important coastal habitats and the climate benefits they provide.

What is Coastal Blue Carbon?

Coastal blue carbon is carbon that is stored in coastal habitats like salt marshes, mangroves, and seagrass beds.

Just like forests on land, coastal habitats capture and store carbon dioxide from the atmosphere, both in plants and in the soil. But compared to forests, coastal habitats do so on a much larger scale. Research shows that mangroves and salt marshes remove (sequester) carbon from the atmosphere at a rate 10 times greater than tropical forests. They also store three to five times more carbon per acre than tropical forests. This is because most coastal blue carbon is stored in the soil, rather than in above-ground plants.

Coastal blue carbon habitats are also sometimes referred to as “carbon sinks,” because they sequester more carbon than they release. They also hold on to it for long periods of time. Carbon found in coastal soils is often hundreds or thousands of years old.

Closure for the Commercial Golden Tilefish Longline Component in South Atlantic Federal Waters on February 10, 2021

February 5, 2021 — The following was released by NOAA Fisheries:

WHAT/WHEN:

The commercial longline component for golden tilefish in federal waters of the South Atlantic will close at 12:01 a.m., local time, on February 10, 2021.  The closure applies to all harvest or possession of golden tilefish with longline fishing gear.

WHY THIS CLOSURE IS HAPPENING:

  • Only golden tilefish longline endorsement holders are allowed to harvest golden tilefish with longline fishing gear.
  • The 2021 commercial catch limit for the golden tilefish longline component is 248,805 pounds gutted weight. NOAA Fisheries predicts this catch limit will be reached by February 10, 2021, and according to the accountability measure, harvest must close to prevent the catch limit from being exceeded.

DURING AND AFTER THE CLOSURE:

  • Golden tilefish harvested with longline fishing gear may not be sold or purchased after the closure. The prohibition on sale or purchase during the closure does not apply to fish that were harvested, landed ashore, and sold prior to 12:01 a.m., local time, on February 10, 2021, and were held in cold storage by a dealer or processor.
  • During the longline closure, a vessel with a golden tilefish longline endorsement may not commercially harvest golden tilefish using hook-and-line fishing gear, and is limited to the golden tilefish recreational bag and possession limits when the recreational sector is open, without regard to where the golden tilefish was harvested (i.e. in state or federal waters).
  • A vessel that does not have a longline endorsement, but has a commercial South Atlantic snapper-grouper unlimited permit, may commercially harvest golden tilefish with hook-and-line fishing gear until the hook-and-line catch limit is reached.
  • The commercial longline component for golden tilefish in federal waters of the South Atlantic will open at 12:01 a.m., local time, on January 1, 2022.

This bulletin provides only a summary of the existing regulations.  Full regulations can be found in the Federal Register or at https://www.ecfr.gov/cgi-bin/text-idx?SID=383bc195ccbeab4fd6bec1c24905df34&node=sp50.12.622.i&rgn=div6.

Surface Slicks are Pelagic Nurseries for Diverse Ocean Fauna

February 5, 2021 — The following was released by NOAA Fisheries:

To survive the open ocean, freshly hatched tiny fish larvae must find food, avoid predators, and navigate ocean currents. Their experiences during these great ocean odysseys have long been a mystery, until now. We have discovered that a surprisingly dense and diverse array of marine animals find refuge in so-called “surface slicks” during early life. To view an immersive, interactive version of this story, check out our story map: Hidden World Just Below the Surface.

Surface slicks are home to the larvae of at least 112 marine fish species, including commercially and ecologically important fish such as mahi-mahi, jacks, and billfish. Serving as makeshift nursery habitats, surface slicks are meandering lines of smooth surface water that collect plankton and shelter-providing debris. They are formed from the convergence of ocean currents, tides, and variations in the seafloor.

“These ‘bioslicks’ form an interconnected superhighway of rich nursery habitat that accumulate and attract thousands of young fish, along with dense concentrations of food and shelter,” says Dr. Jonathan Whitney, a research marine ecologist for NOAA and lead author of the study, published today in Scientific Reports. “The fact that surface slicks host such a large proportion of larvae, along with the resources they need to survive, tells us they are critical for the replenishment of adult fish populations.”

That  larvae hosted in slick nurseries grow up and radiate out into neighboring ecosystems. There, they join adult fish populations from shallow coral reefs to the open ocean to the bottom of the deep sea.

What’s more, many forage (prey) fish, like flying fish, spend their larval and juvenile life stages in surface slicks. “These biological hotspots provide more food at the base of the food chain that amplifies energy up to top predators,” says study co-author Dr. Jamison Gove, a research oceanographer for NOAA. “This ultimately enhances fisheries and ecosystem productivity.”

NEFMC Votes to Submit Groundfish Framework 61 with Universal Sector Exemption for Redfish

February 5, 2021 — The following was released by the New England Fishery Management Council:

The New England Fishery Management Council voted on January 26, 2021 to include a universal sector exemption for redfish in Framework Adjustment 61 to the Northeast Multispecies Fishery Management Plan. If approved by NOAA Fisheries, the exemption would allow groundfish sector vessels to target redfish with 5.5-inch codend mesh within a larger Redfish Exemption Area in the future than was available in the 2020 fishing year.

Following this decision, the Council voted to submit Framework 61 to NOAA’s Greater Atlantic Regional Fisheries Office (GARFO) for review and implementation. The target implementation date is May 1, 2021, the start of the new fishing year.

The Council signed off on all other Framework 61 measures, including 2021-2023 specifications for groundfish stocks based on updated assessment information, during its December 2020 meeting. A recap is available here.

More ships must slow to protect right whales, NOAA says

February 5, 2021 — A detailed analysis shows that speed limits for ships have reduced risk for collisions with endangered right whales, but there are significant gaps in compliance – particularly off U.S. Southeast ports, where burgeoning cargo traffic is on a long-term upswing, the National Oceanic and Atmospheric Administration (NOAA) reported.

Drafted in June and released on 21 January, the NOAA review used automatic identification system (AIS) data to track total vessel transits through the two types of speed limit zones: Seasonal Management Areas (SMAs), frequented by whales at known times of year where ships over 65 feet in length are mandated to make way at 10 knots or less; and dynamic management areas (DMAs), where NOAA issues temporary advisories to mariners to voluntarily observe the 10-knot limit when whales have been reported.

HAWAII: Two of three dead monk seals on Kauai likely died from drowning in lay nets

February 4, 2021 — Post-mortem exams have revealed that two of the three Hawaiian monk seals that were found dead on Kauai’s north shore last year likely drowned in lay nets, wildlife officials said today.

Three seals were found dead separately — in September, November and December — all in the Anahola area of Kauai.

The unusual succession of deaths prompted an investigation by the National Oceanic and Atmospheric Administration Office of Law Enforcement, which was offering a reward of up to $20,000 for information leading to the issuance of a civil penalty or criminal conviction in one or both of these endangered Hawaiian monk seals.

The first seal, a juvenile male identified as RL52, was found dead around Sept. 10 after having just been spotted a week earlier nearby in good condition. The second seal, an untagged, juvenile female, was found dead around Nov. 18.

NOAA now believes the first two seals found in September and November likely died after becoming entangled in lay gill nets, a news release from the state Department of Land and Natural Resources said, based on recent lab test results and information gathered by law enforcement officials.

They should be heading north, but whale and her calf are going south. Scientists worried

February 2, 2021 — The coasts off Northeast Florida, Georgia and South Carolina are the only known spots in the ocean where North Atlantic right whales give birth to their calves. After birth, the mother and calf usually swim north to New England.

But a right whale that recently gave birth to a calf is heading in the wrong direction, according to federal marine scientists.

The 12-year-old adult and her baby were first seen off Amelia Island near Jacksonville on Jan. 21. Scientists with the National Oceanic and Atmospheric Administration are concerned because the pair was next spotted last Wednesday, Jan. 27, much farther south near the Lake Worth Inlet just north of West Palm Beach in South Florida.

“In this case, the pair is heading south, into areas they normally don’t go, making it important for people to be on the lookout for them,” said Allison Garret, spokeswoman with NOAA Fisheries.

Oceana takes government to court again over anchovy limits

February 2, 2021 — Oceana continues to challenge the U.S. government over federal catch limits on anchovy the organization claims ignore scientific advice.

In a statement on Monday, 1 February, the environmental conservation group announced it has filed two legal actions to support what it calls “science-based management” of the northern anchovy stock. The organization has taken NOAA Fisheries to court over anchovy catch limits multiple times over the past few years, and alleged in 2019 that it had failed to protect the anchovy stock in Northern California.

As Warming Oceans Bring Tough Times to California Crab Fishers, Scientists Say Diversifying is Key to Survival

February 1, 2021 — California’s Dungeness crab fishermen have had a rough year. Poor meat quality, endangered whales migrating too close to shore and price disputes with wholesalers kept crab pots on boats for nearly two months. The delays left families without their cherished holiday centerpiece and fisherman without the funds that normally pay their bills the rest of the year.

But as rising ocean temperatures threaten to make fishery closures routine, it will be even harder to count on crab for holiday meals—or livelihoods. Over the past decade, warming sea waters have produced harmful algal blooms that contaminate crab meat with domoic acid, a neurotoxin that can cause seizures, memory loss and other serious symptoms and has been blamed for poisoning and stranding scores of sea lions in California every year. State officials delayed three out of the last six crab seasons to protect public health after an unprecedented multiyear marine heat wave, dubbed “the blob,” hit the north Pacific Ocean in 2013.

The blob precipitated a series of extraordinary events: it caused a massive harmful algal bloom that led to record-breaking domoic acid concentrations, which in turn caused first-of-its-kind closures of the West Coast’s most valuable fishery, from southern California to Washington state. But in doing so, it also set up a natural experiment that researchers harnessed to reveal strategies that could help food-producing communities recover from climate-driven disturbances.

New whale species discovered in the Gulf of Mexico — and it’s endangered

February 1, 2021 — A new species of baleen whale has been identified in the Gulf of Mexico.

Researchers with the National Oceanic and Atmospheric Administration (NOAA) published a paper earlier this month in Marine Mammal Science explaining that a whale previously thought to be a subspecies of the Bryde’s whale is actually a new species entirely.

Bryde’s whales live in the warm waters of the Atlantic, Pacific and Indian oceans and are closely related to the blue and humpback whale.

Patricia Rosel, a research geneticist with NOAA Fisheries who led the study, said genetic data gathered from the newly discovered species in the early 2000s hinted at a divergent evolutionary lineage, but more concrete evidence came after researchers were able to examine the skull of the species that washed up on a Florida beach in 2019.
