Extended: Slow Speed Zone South of Nantucket to Protect Right Whales

October 5, 2020 — The following was released by NOAA Fisheries:

In Effect to October 20

NOAA Fisheries announces an extension to the previously triggered voluntary vessel speed restriction zone (Dynamic Management Area  or DMA) south of Nantucket.

This DMA was originally triggered by an August 31, 2020, sighting of an aggregation of right whales and previously extended until October 9, 2020. A  New England Aquarium aerial survey observed an aggregation of whales in this area on October 4. Since the current DMA is set to expire in less than a week we are extending it until October 20, 2020.

Mariners, please go around this areas or go slow (10 knots or less) inside this area where groups of right whales have been sighted.

South of Nantucket DMA is in effect to October 20.

New Videos Put Restitution to Work for Imperiled Coho Salmon

October 2, 2020 — The following was released by NOAA Fisheries:

Coho salmon once supported a wealth of tribal, commercial, and recreational fisheries along the West Coast. Today some populations of the swift silvery fish are nearing extinction. The good news? We can reverse that decline, as biologists and others demonstrate in a new video series that offers hope for California’s endangered fish and wildlife species.

The video series was produced in collaboration with state and federal fish and wildlife agencies with a community service payment made by a real estate development company. The company pleaded guilty in 2016 in a federal criminal case involving the endangered California tiger salamander. In a separate but related case, the owner of the development company agreed to protect a 107-acre ranch in Contra Costa County that provides habitat for endangered species.

The Saving Species Together video series and a supporting website highlight collaborative efforts to recover endangered species including:

  • California tiger salamander
  • San Joaquin kit fox
  • Western snowy plover
  • Southern Oregon/Northern California Coast coho salmon

“When we collaborate, we can make very real progress in protecting these species,” said Bob Pagliuco, a NOAA Fisheries habitat restoration specialist. He worked with Humboldt Redwood Company and Trout Unlimited to build an off-channel pond for juvenile coho in the Eel River Watershed. The coho salmon video tells how a supportive landowner helped return fish to their historic habitat. “The educational campaign launched by these videos is a way to help the public understand how habitat destruction affects species and how we can protect habitats to save these species.”

Video Research Investigates Effects of Shellfish Farming on West Coast Nearshore Habitat

October 2, 2020 — The following was released by NOAA Fisheries:

The underwater video scene is full of life. A school of sinewy fish darts across the screen while a crab rummages along the seafloor. A flatfish, camouflaged like the sandy bottom, doesn’t seem to mind when the crab crawls over its back to approach an oyster.

Scientists from NOAA Fisheries’ Northwest Fisheries Science Center are collecting this video and more like it. They want to assess how marine life uses, and may even benefit from, habitat in and around farms growing oysters and other shellfish. They are teaming up with Microsoft to use computers and artificial intelligence to scan hours of video within seconds for different species of interest.

This particular video reveals the underwater landscape of Hama Hama shellfish farm in Hood Canal, Washington, one of many partners assisting with the study. Other local shellfish growers and the Pacific Shellfish Institute are also taking part.

“We collected the video as one way to assess how fish and invertebrates use shellfish aquaculture habitats compared to areas of the nearshore that don’t have aquaculture,” said Beth Sanderson, a Northwest Fisheries Science Center research scientist. Researchers collected the video over the past several years to assess the way species use, and feed in, different habitat types.

Shellfish farming is one of the most valuable parts of the Northwest aquaculture industry. It generated close to $100 million annually for the regional economy and provides close to 1,500 jobs prior to the pandemic. Shellfish farms occupy more than 25,000 acres in the Northwest. Researchers and managers want to understand how farming practices affect marine life in the shallow and highly productive nearshore waters where oysters and other shellfish grow.

“We’ve seen basically all of the fish you’d expect in the nearshore—herring and other forage fish, varieties of perch and sculpin, juvenile salmon, along with diving ducks, harbor seals and more,” Sanderson said. “There’s an amazing variety of life in the shallows of the Pacific Northwest, and we are seeing for the first time how many of these species use habitats within and near shellfish farms.”

Council OKs At-Sea Monitoring For All NE Groundfish Trips

October 2, 2020 — The New England Fishery Management Council on Wednesday approved a 100% target for the at-sea monitoring of sector-based groundfish vessels, but stipulated that the requirement will be contingent upon federal funding, at least for now.

The council voted via webinar to approve Amendment 23 to the Northeast Multispecies Fishery Management Plan. If the measure is approved by NOAA Fisheries, it could go into effect in early 2022. Under the amendment, the monitoring of fish landed and discarded at sea could be done with either human monitors or video cameras.

The vote capped three years of discussion and months of public hearings on how to best improve groundfish fishery regulation in New England. Environmental groups such as the Conservation Law Foundation charge that strong oversight is needed to maintain a sustainable fishery. Fishermen for the most part have expressed grave concern about the cost, which could be as high as $700 per vessel per day.

The measure as passed states that the monitoring program will be contingent upon full federal funding for the first four years of the program. In year five, the federal funding target would be reduced. A review process was also put in place.

Behind the Scenes of the Most Consumed Seafood

October 1, 2020 — The following was released by NOAA Fisheries:

Shrimp, tuna, clams—the most popular seafood items in the United States are familiar names to both seafood lovers and the occasional consumer. You may have wondered about the environmental impact of consuming more of a popular product.

We’ve got good news: U.S. seafood is sustainable seafood! Thanks to our robust quotas, retention limits, and other management measures, you can be confident that U.S. seafood products were harvested sustainably.

Around 75 percent of the shrimp harvested in the United States comes from the Gulf of Mexico. Three species dominate the catch there: white shrimp, pink shrimp, and brown shrimp. Each of these species currently have population levels above the targets set by scientists.

Federally permitted shrimp fishermen are required to report their landings. They also provide information on fishing effort, including the number of fishing trips they take. The data is used in shrimp stock assessments and to support the sustainable management of red snapper. Depending on the gear they use, shrimpers must also use special equipment that reduces incidental catch, including sea turtle bycatch.

Aquaculture Supports a Sustainable Earth

October 1, 2020 — The following was released by NOAA Fisheries:

The United Nations maintains 17 Sustainable Development Goals that serve as a framework for international cooperation to help people and the planet thrive.

A recent study from the UN shows that aquaculture can improve food security and nutrition by increasing the amount of seafood available for people to eat. If done correctly, aquaculture increases food production, boosts economic growth in coastal and rural areas, and can help keep waterways clean.

Explore how aquaculture fits into the UN’s sustainability goals:

1. Shellfish Beds Help Restore Our Waterways

Shellfish such as oysters, clams, and mussels are not just a beach barbecue staple; they serve an important role in waterways. However, in some areas these shellfish have been largely lost from coastal ecosystems. Restoring and farming shellfish beds allows these bivalves to clean the water as they filter feed, serve as habitats for smaller organisms, and can even help prevent shoreline erosion. Preserving ecosystems, safeguarding biodiversity, and reversing land degradation are significant components of sustainable aquaculture.

Wind Influences Pollock Success in the Gulf of Alaska

September 29, 2020 — The following was released by NOAA Fisheries:

For young Alaska pollock in the Gulf of Alaska, survival may depend on which way the wind blows.

A study conclusively shows for the first time that year-to-year variation in the geographic distribution of juvenile pollock in the Gulf of Alaska is driven by wind. Depending on wind direction, water movement may retain juvenile fish in favorable nursery habitats, or transport them away. Young fish that are transported to less favorable habitats are less likely to contribute to year-class strength— the abundance of adults available to the valuable Gulf of Alaska pollock fishery.

For NOAA Fisheries biologist Matt Wilson of the Alaska Fisheries Science Center, the new study addressed a longstanding question.

“When we began this research, scientists thought that lots of juvenile fish would mean a relatively strong adult year-class. But in some years our surveys found a lot of juvenile pollock, followed by a weak year class. In other years a high number of juveniles grew into a strong year class,” Wilson said. “We undertook this research to better understand why large numbers of juveniles do not always translate into a high abundance of adults.”

Wilson and co-author Ned Laman also observed that the geographic distribution of juveniles was highly variable from year to year. In some summers, a very large proportion of the juvenile population was far southwest of the main spawning grounds.

“In this study we asked: what is the cause and consequence of year-to-year geographic variability in the distribution of juvenile pollock in the Gulf of Alaska?” Wilson said.

The Impacts of Ghost Nets on Coral Reefs

September 28, 2020 — The following was released by NOAA Fisheries:

Ghost nets are silently drifting through the Northwestern Hawaiian Islands, snagging on coral reefs and entangling wildlife. Scientists in the Pacific Islands have observed ghost nets tumbling across expansive coral reef environments. They break, shade, and abrade coral, preventing them from healthy growth. These lost or abandoned fishing nets are a persistent threat that accumulate over time, but we know little about the damage nets inflict upon corals.

In 2018, our marine debris team quantified the damaging effects of ghost nets on coral reefs of the Northwestern Hawaiian Islands for the first time. They found that regardless of net size or algae growth, corals were lost. They recently published their findings in Marine Pollution Bulletin.

The Northwestern Hawaiian Islands stretch for more than 1,243 miles northwest of the main Hawaiian Islands. They contain 124 mostly uninhabited small islands, atolls, reefs, and submerged banks. They are recognized as a UNESCO World Heritage Site and are encompassed by the Papahānaumokuākea Marine National Monument. Within these protected waters, far from human inhabitants, ghost nets are leaving their mark on reefs. But how much of an impact are these nets having on corals?

FB20-059: Seasonal Prohibition on Fishing for or Possession of Blackfin, Vermilion, Black, or Silk Snapper in U.S. Caribbean Federal Waters

September 28, 2020 — The following was released by NOAA Fisheries:

WHAT IS HAPPENING AND WHEN:

NOAA Fisheries reminds fishermen and the public of the annually recurring seasonal prohibition on fishing for or possession of blackfin, vermilion, black, or silk snapper in U.S. Caribbean federal waters.

  • This closure begins at 12:01 a.m., local time, on October 1, 2020, and extends through 11:59 p.m., local time, December 31, 2020.
  • The prohibition on possession does not apply to blackfin, vermilion, black, or silk snapper harvested and landed ashore prior to the closure.

Federal waters in the U.S. Caribbean consists of those waters extending from the three-nautical mile seaward boundary of the Territory of the U.S. Virgin Islands, and the nine-nautical mile seaward boundary of the Commonwealth of Puerto Rico, out to 200 nautical miles offshore.

WHY THIS CLOSURE IS HAPPENING:

This seasonal closure protects blackfin, vermilion, black, and silk snapper when they are spawning (reproducing) and therefore more vulnerable to fishing pressure.
