World’s Most Ambitious Satellite Telemetry Study of Foraging Green and Hawksbill Sea Turtles

September 25, 2019 — The following was released by NOAA Fisheries:

NOAA Fisheries is pioneering what has become the most rigorous satellite tagging study of foraging green sea turtles and hawksbill sea turtles in the world. NOAA researchers Drs. Alexander Gaos, Summer Martin, and Camryn Allen recently returned from their latest expedition to Guam and the Commonwealth of the Northern Mariana Islands (CNMI). When they see a turtle, they free dive and attempt to hand-capture it. Local resident and freediving expert Jessy Hapdei leads the hand-capture effort. He has been involved in the project since its inception.

The most recent survey trip took place in early September 2019. The research team planned the mission to coincide with good weather dates. The eastern and northern coasts of the islands of Guam and Saipan have been impossible to access in the past, because challenging weather conditions persist during much of the year. These areas are important to the regional study of sea turtle movement ecology. The team’s planning efforts were rewarded with six outstanding field days—they captured, measured, and tagged 19 green turtles and two hawksbill turtles. They used flipper tags as well as satellite tags. Satellite tags give information on the fine-scale movements of turtles for several months. Flipper tags can last years or even decades and allow scientists to identify turtles long after the satellite tag has fallen off.

Since 2011, the research team has observed more than 600 turtles. They have hand-captured more than 200 and equipped 125 with satellite tags. Of the turtles equipped with satellite tags, 111 have been green turtles and 14 have been hawksbill turtles.

As bluefin recover, a new fight about how to fish for them

September 25, 2019 — A federal plan that could loosen the rules about fishing for one of the most debated species in the ocean has attracted the attention of fishermen and environmentalists, some of whom fear years of conservation work could be undone.

Preservation of the Atlantic bluefin tuna has long been a subject of international debate, and sometimes discord. The giant sushi fish, which occasionally sell for more than $1 million and often weigh several hundred pounds, are at a fraction of historical population levels but have shown positive signs in recent years.

The federal government is considering some changes to the way the fish are managed. The National Oceanic and Atmospheric Administration has said some of the changes would give fishermen who use longlines, a method of fishing used to catch large fish, more flexibility by increasing their amount of open fishing area, including in the Gulf of Mexico.

The Gulf of Mexico is a critical spawning area for bluefin, and parts of it are closed down to longliners in the spring to protect the fish. Reopening it to fishing could jeopardize the bluefin stock in U.S. waters and beyond, said Shana Miller, senior officer for international fisheries conservation with the Ocean Foundation.

New Seafloor Maps Reveal Habitat Sculpted by Ancient Glaciers

September 24, 2019 — The following was released by NOAA Fisheries:

New seafloor maps show for the first time the course of ancient ice masses. They show how they shaped essential habitat for the western Gulf of Alaska’s abundant fish, seabirds, and marine mammals.

Scientists wove together historical and modern data—from century-old hand-drawn charts to modern multibeam surveys. They created a highly detailed view of the seafloor and its geological features. The results will help scientists better understand the habitat requirements of many species and the oceanographic processes that influence their success.

The western Gulf of Alaska is both ecologically and economically important. Shelikof Strait, a major feature of the region, holds special importance as spawning ground for the Gulf’s biggest stock of walleye pollock. Together with other Alaska pollock stocks, they are the target of the world’s largest fishery. Shelikof Strait is also home to rare species like the mysterious Pacific sleeper shark. Within the Gulf of Alaska bottom trawl survey area, almost half of all sleeper shark occurrences are in Shelikof Strait.

Despite its importance, until now much of the western Gulf of Alaska had not been mapped in sufficient detail to describe the geological features of this vital habitat. To create and analyze new maps, NOAA Fisheries and U.S. Geological Survey scientists teamed up to bring together geographical and geological expertise.

ALASKA: Biomass of snow crab in Bering Sea grew slower than expected

September 24, 2019 — Last week’s Crab Plan Team, an advisory group to the North Pacific Fisheries Management Council, heard some good news about increased biomass of mature male snow crab in the US state of Alaska’s Bering Sea, but the survey showed less than what was predicted earlier this year.

The quota for the Bering Sea and Aleutian Islands crab fisheries will be set by Alaska Department of Fish and Game (ADF&G) in mid-October. Alaska’s crab resources are jointly managed by the National Oceanic Atmospheric Administration’s National Marine Fisheries Service (NMFS) and the ADF&G.

There was a “smaller increase in mature male biomass (MMB) of snow crab than projected, but it is still increasing”, noted stock assessment author Cody Szuwalski of NMFS. He and other scientists recommended one of eight assessment models that would result in a preferred MMB of 111.4 metric tons, with an OFL of 54,900t, 85% higher than last year, to the plan team.

Researching and Rescuing Hawaiian Monk Seals and Green Sea Turtles

September 24, 2019 — The following was released by NOAA Fisheries:

NOAA field biologists returned to Honolulu after 3 months at remote camps in the Northwestern Hawaiian Islands. They researched and rescued some of the most iconic and endangered species in Hawaiʻi—Hawaiian monk seals and green sea turtles.

This year, our field biologists established protected species camps at five atolls:

  • French Frigate Shoals.

  • Laysan Island.

  • Lisianski Island.

  • Pearl and Hermes Reef.

  • Kure Atoll.

Our field teams also conducted population assessment surveys at Nihoa, Mokumanamana (Necker), and Midway Atoll.

NOAA has operated monk seal research camps at all major breeding sites for 36 years. We have maintained French Frigate Shoals turtle nesting records, which stretch back 47 years. Several of the field researchers have been around for decades. They have some of the most consistent sets of eyes and ears in the Papahānaumokuākea Marine National Monument. They are able to observe changes in the ecosystem, improving our response to threats to these important species.

Collins proposes reforms to support Maine lobster industry, protect whales

September 23, 2019 — U.S. Sen. Susan Collins (R-ME) proposed changes to federal reforms that would protect whales and support the Maine lobster industry.

Sen. Collins joined her congressional colleagues from Maine in jointly responding to the National Oceanic and Atmospheric Administration’s (NOAA) call for input to develop modifications to the proposed regulations developed by NOAA’s Atlantic Large Whale Take Reduction Team (TRT).

In a letter sent on Tuesday to the NOAA TRT team, the delegation recommended measures that would help reduce right whale fatalities without threatening the lobster industry, including more Maine-specific gear markings, improved monitoring, support for the Maine Department of Marine Resources’ proposal to preserve the current regulatory exemptions line, and the state’s plan to improve data collection.

Marine heat wave dubbed ‘Blob’ resurges in Pacific; mass deaths of sea life feared

September 23, 2019 — Across vast stretches of the Pacific Ocean extending from Hawaii north to the shores of Alaska, and southeast to near California, a new marine heat wave is underway.

This event is widely referred to as ‘‘The Blob Part Two,’’ or just another ‘‘Blob.’’ The first event, which took place from 2014 through 2016, earned that odd moniker based on its bold red appearance on maps of ocean surface temperatures.

The new incarnation already has caused coral bleaching in the Hawaiian islands and may be tied to strandings of marine mammals along the California coast. If it intensifies and seeps into deeper waters, this marine heat wave could favor another drought in California by altering the jet stream flowing across the Pacific.

Massachusetts meeting could have big consequences for US groundfish harvesters

September 23, 2019 — The financial well being of groundfish harvesters in the Northeastern US could be heavily influenced by a four-day meeting that kicks off in Gloucester, Massachusetts, Monday, the Gloucester Daily Times reports.

Wednesday is the key day, the newspaper advises. That’s when the meeting, held by the New England Fishery Management Council (NEFMC) at the Beauport Hotel, is expected to spend an entire afternoon focused on groundfish, including Amendment 23.

Passed by the NEFMC and approved by the National Oceanic and Atmospheric Administration’s National Marine Fisheries Service (NMFS), Amendment 23 is to improve the accuracy of multispecies groundfish catch reporting data by setting industry-funded minimum coverages.

UMaine Orono receives $1.6M grant for sustainable aquaculture

September 20, 2019 — The University of Maine at Orono received a $1.6 million grant to advance sustainable aquaculture in Maine.

According to a release from the university, Maine Sea Grant researchers at the University of Maine were granted the money from the NOAA National Sea Grant to lead four projects in collaboration with the aquaculture industry, management, and community partners.

“Thousands of Mainers rely on marine industries for their livelihoods, and aquaculture is a promising area for growth,” said U.S. Sens. Susan Collins and Angus King.

According to NOAA fisheries, the United States imports 85% of its seafood, which has resulted in a $14 billion trade deficit- leading to new opportunities in aquaculture to meet demands of seafood consumption.

Feds propose major habitat protections for killer whales

September 20, 2019 — U.S. protections for the waters that a group of endangered orcas call home could soon expand beyond the Seattle area to encompass much of the West Coast, from the Canadian border to central California.

The National Oceanic and Atmospheric Administration issued a proposal Wednesday to increase the critical habitat designation for southern resident killer whales by more than sevenfold under the Endangered Species Act.

Just 73 orcas remain in the Pacific Northwest population, the lowest number in more than three decades. They’re struggling with a lack of chinook salmon, their preferred prey, as well as toxic contamination and vessel noise.

The NOAA proposal calls for an additional 15,626 square miles (40,471 square kilometers) of federally protected habitat that would run from the border with Canada, down south to Point Sur, California.

The designation means federal agencies must ensure that activities they pay for, permit or carry out do not harm the habitat, but it does not generally affect approved recreational or commercial activity such as whale watching and shipping, said Lynne Barre, NOAA Fisheries’ recovery coordinator for the whales.
