NOAA Fisheries proposes habitat protection for threatened corals in Northwestern Hawaiian Islands

December 5, 2023 — NOAA Fisheries has proposed a rule to designate critical habitat for five threatened reef-building coral species in the Pacific Islands region. This rule refines an earlier proposal in 2020 for Endangered Species Act-listed Indo-Pacific coral species following the inclusion of new data and information received from the community during the previous public comment period.

“Pacific coral reefs play an important role in shoreline protection, while also supporting the local economy and serving as biodiverse ecosystems,” said Dawn Golden, assistant regional administrator for NOAA Fisheries Pacific Islands Regional Office. “Despite facing threats – including temperature rise and pollution – designating critical habitat aims to minimize the impacts of these threats and promote coral resilience.”

Under the Endangered Species Act, NOAA Fisheries is proposing to designate areas containing habitat characteristics where Acropora globiceps, A. retusa, A. speciosa, Euphyllia paradivisa, and Isopora crateriformis reproduce, disperse, settle and mature. These include select locations in the waters around 16 islands and atolls.

From Fishermen To Rugby Players, Climate Change Has Become A Fact Of Life In Fiji

February 17, 2022 — When Shahadat Ali was learning how to fish, he was taught to put the smaller fish back into the ocean. But the quality, size and amount of fish have decreased so dramatically that he now has to keep every fish that swims into his net.

“Times are hard — it’s a struggle,” said Ali, who lives on the outskirts of Nasinu, the most populous town on the island of Viti Levu in Fiji.

Ali’s 72-year-old uncle, Iqbal Shah, has been fishing since he was a teenager and has seen the ocean he loves change drastically over his lifetime.

“In one week we used to catch 300 to 400 kilograms, sometimes 500 kilograms, but now if you fish one week, you can’t hardly get about 100 kilograms (220 pounds),” Shah said. “It is very hard.”

Bleached reefs still support nutritious fish, study finds

January 21, 2022 — Escalating ocean temperatures stemming from climate change are devastating the world’s tropical coral reefs. In response to the stress, corals, which are animals, sometimes unceremoniously jettison the algae that live within them. That expulsion drains the color from the reefs in what’s known as bleaching. In the severest cases, it can kill the coral, which need the algae to provide them with nutrients, oxygen and waste management.

At the same time, millions of people in the tropics eat fish that live on these reefs. And today, the widespread bleaching of tropical reefs, which is expected to continue as the Earth heats up, has thrown into question how those fisheries and the communities that depend on them for sustenance will respond.

Now, a new study published Jan. 6 in the journal One Earth has found that in certain circumstances, critical nutrients for human development found in reef fishes remain available even after mass bleaching has occurred.

“An important message here is that climate-impacted reefs can still provide some important ecosystem services, and therefore should still be considered in management plans and conservation,” said Camille Mellin, a quantitative ecologist at the University of Adelaide in Australia, who was not involved in the study.

The race to rescue Florida’s diseased corals

August 30, 2021 — On any given day, aquarist Sara Stevens whips up a slurry of plankton, amino acids and other powdered nutrients to feed a voracious group of rescued corals. Using a turkey baster, she blasts the cloudy concoction over each colony made up of thousands of individual organisms called polyps, watching as their tiny tentacles slowly extend and envelop the meal. For the especially carnivorous ones housed at the Butterfly Pavilion in Westminster, Colo., she hand-feeds them full-bodied krill.

This ritual is just one part of the painstaking care Stevens and other aquarists across the country have been giving to a group of corals rescued from disease-ridden waters in Florida. Their future depends on it.

Since 2014, a mysterious illness known as stony coral tissue loss disease has plagued Florida’s reef tract, killing off nearly half the state’s hard corals, whose rigid limestone skeletons provide the architectural backbone of the largest bank reef in the continental United States. By 2018, it became clear that without drastic intervention, these corals would face imminent localized extinction.

“We couldn’t sit back and watch these corals disappear,” said Stephanie Schopmeyer, a coral ecologist from the Florida Fish and Wildlife Conservation Commission.

To save them, scientists devised a plan to remove the most vulnerable species from their natural habitat and create a land-based gene bank that would serve as a modern day ark for the animals. They knew that to succeed, time was of the essence and collaboration was key. What followed was an unprecedented effort, in which dozens of federal and state organizations, universities, zoos and aquariums joined forces to rescue thousands of Florida’s endangered corals.

HAWAII: Marine debris team joins the Papahanaumokuakea Marine Debris Project to remove fishing nets from coral reefs

August 30, 2021 — NOAA and the Papahanaumokuakea Marine Debris Project partner to remove derelict fishing nets from coral reefs across the Papahanaumokuakea Marine National Monument.

Scientists and divers from NOAA’s Pacific Islands Fisheries Science Center are teaming up with divers from the Papahanaumokuakea Marine Debris Project for a 30-day mission to remove marine debris from the islands and atolls within the Papahanaumokuakea Marine National Monument.

The team departed Honolulu on the M/V Imua on Tuesday. We expect the ship to return with more than 110,000 pounds of derelict fishing gear and other marine debris at the end of September.

The 2021 marine debris removal mission will focus on surveying for and removing marine debris from coral reefs and coastal environments. They will be working on Kamole (Laysan Island), Kamokuokamohoali‘i (Maro Reef), Kapou (Lisianski Island), Kuaihelani (Midway Atoll), Holaniku (Kure Atoll), and Manawai (Pearl and Hermes Atoll).

‘Sticky questions’ raised by study on coral reefs

August 12, 2021 — A new UBC study on the impact of climate change on coral reefs is raising sticky questions about conservation.

It found coral in more polluted and high traffic water handled extreme heat events better than a more remote, untouched reef.

The new study, conducted with researchers from the Republic of Kiribati’s Ministry of Fisheries and Marine Resource Development, focused on two atolls in the Central Pacific, located 59 kilometers apart.

“Because of El Niño-Southern Oscillation, which causes ocean temperatures to fluctuate along the equator from year-to-year, these coral reefs experience heat stress more often than reefs in other parts of the world,” says the study’s lead author Sara Cannon, a Ph.D. student at UBC’s Institute for the Oceans and Fisheries and the department of geography.

ASMFC Releases Update to Profiles of State Artificial Reef Programs and Projects

July 8, 2021 — The following was released by the Atlantic States Marine Fisheries Commission:

The Atlantic States Marine Fisheries Commission announces the release of the Update to ASMFC’S Profiles of State Artificial Reef Programs and Projects. This document provides a summary for each state’s artificial reef program and features highlights that have occurred since the release of the first edition of this publication in 1988. Since then, many Atlantic states have expanded their programs; deployed a variety of artificial reefs using best management practices for construction, materials, and siting; and have monitored sites for use – both by fishers and divers, as well as by marine life.

Artificial reefs have been used for centuries to enhance fishery resources and fishing opportunities by creating habitat for fish and invertebrate species through the use of man-made materials. They also provide underwater structures for SCUBA divers and facilitate reef-related research. Artificial reefs are typically constructed from dense materials, such as decommissioned ships and barges; concrete and steel demolition debris; and dredge rock. When properly constructed and strategically sited, artificial reefs can enhance fish habitat and total biomass, increase access to quality fishing grounds that benefit coastal economies, and provide managers with another option for the conservation and management of fishery resources.

The publication identifies more than 335 permitted artificial reefs spanning 11 Atlantic coast states. It also provides a brief history of each program; highlights specific projects; provides details on state funding; and includes maps of reef locations. Over the past 30 years, artificial reef programs have implemented new technologies to designate sites, mapped existing materials, and evaluated established reef habitats. There are many examples of state programs collaborating with universities to study reef impacts, as well as examples of partnerships across state agencies, with the federal government, and with NGOs and private companies to secure reefing materials. Update to ASMFC’S Profiles of State Artificial Reef Programs and Projects is available at http://www.asmfc.org/files/Habitat/ArtificialReefs/ASMFC_Profiles_StateArtificialReefPrograms_Projects_July2021.pdf.

Large-scale coral restoration beginning in Florida Keys National Marine Sanctuary

April 20, 2021 — The following was released by NOAA:

In the spirit of this year’s Earth Day theme “Restore our Earth,” NOAA and partners are beginning a three-year effort to outplant more than 60,000 fragments of nursery-raised coral at Eastern Dry Rocks Sanctuary Preservation Area off the coast of Key West, Florida. This is the first large-scale endeavor dedicated to Mission: Iconic Reefs, the unprecedented effort to restore seven coral reefs within Florida Keys National Marine Sanctuary.

“Outplanting at this unprecedented scale is one of many immediate actions needed to address the rapid decline in our treasured coral reefs,” said Ben Friedman, acting NOAA Administrator. “The Florida Keys has become a world leader in coral restoration with new techniques for addressing threats and accelerating coral growth, thanks to an unprecedented collaboration between NOAA, our partners, and a community of stewards.”

Eastern Dry Rocks contains a concentration of bank reef habitats that are ecologically and economically important to the Florida Keys. The elkhorn and staghorn corals that are being transplanted across more than nine acres include a high number of distinct genetic strains representing the historical diversity found on these reefs, and genotypes that have exhibited the highest survival and growth rates. Practitioner partners that will assist in the outplanting grew the corals in their respective nurseries over six to eight months.

NOAA and the National Fish and Wildlife Foundation awarded a $5 million grant through the National Coastal Resilience Fund to the National Marine Sanctuary Foundation, in partnership with Mote Marine Laboratory & Aquarium and Coral Restoration Foundation™ to restore Eastern Dry Rocks. The grant is the largest one-time investment since the initiative was announced in December 2019.

Scott Winters, CEO of Coral Restoration Foundation, said “Coral Restoration Foundation has already begun a massive expansion of our Coral Tree Nursery in Key West to support the restoration of Eastern Dry Rocks. Since January 2021, we have now replenished the site with more than 1,085 genetically diverse staghorn and elkhorn corals and are well on our way to hitting our target of 7,350 by the end of the year. Knowing that we are not doing this alone, that this work is part of a much larger, coordinated effort, gives us a renewed sense of hope for the future of the Florida Keys.”

“We are excited to press forward with the application of Mote’s innovative science-based coral restoration of genetically-resilient corals on such a broad scale at Eastern Dry Rocks,” said Michael P. Crosby, Mote Marine Laboratory & Aquarium President & CEO. “Mission: Iconic Reefs is one of the largest reef restoration efforts in the world, and the collaborative efforts of Mote, NOAA, and our partners is unprecedented in this field. Florida’s Coral Reef is vital to our environment and economy, so Mote will continue to maximize our restoration efforts in support of Mission Iconic Reefs whenever possible.”

In later stages of the project, students and faculty of College of the Florida Keys will also help reintroduce thousands of herbivores, like the Caribbean King Crab, to the site to serve as natural grazers that help sustain a healthy ecosystem.

“In many ways, Eastern Dry Rocks serves as a test case for the other six Iconic Reef sites—from research and development on grazers to refinement of methodologies for maintenance and preparation,” said Sarah Fangman, Florida Keys National Marine Sanctuary Superintendent. “Lessons learned from Eastern Dry Rocks will form the basis for standard operating procedures and implementation plans of future Iconic Reef sites.”

Informed by years of research, successful trials, and expertise from dozens of coral scientists and restoration practitioners, NOAA believes this scientific and collaborative restoration plan will put Florida’s reefs on track for recovery and demonstrate how restoration can support a vibrant, sustainable, local economy and help buffer communities from coastal storms. The reef track in the Keys attracts millions of visitors per year, accounting for more than $2 billion of economic impact.

“Florida Keys’ iconic reefs, including Eastern Dry Rocks, are the basis for thriving ecosystems underwater and the critical tourism economy on dry land,” said Kris Sarri, president and CEO of the National Marine Sanctuary Foundation. “This project will transform how we approach coral restoration.”

U.S. coral reefs’ health assessed for the first time on a national scale

November 11, 2020 — The following was released by NOAA:

Coral reefs in both the Pacific and Atlantic oceans received a “fair” score in the first-ever condition status report for U.S. coral reefs released by NOAA and the University of Maryland Center for Environmental Science (UMCES) today. While the overall scores were “fair,” the report highlights coral reefs are vulnerable and declining. This is the first time coral reefs in all U.S. states and territories have been assessed using standardized monitoring data, creating datasets that offer a baseline of coral health on a national scale.

The U.S. Coral Reef Condition Status Report was developed by NOAA’s National Coral Reef Monitoring Program and UMCES’s Integration and Application Networkoffsite link using data collected between 2012 and 2018. The scores are denoted as “very good,” “good,” “fair,” “impaired,” and “critical.” The report was based on four categories when assigning a score: corals and algae abundance, reef fish populations, influence of climate on coral reefs, and human connections to reefs.

“Considering the more than $3.4 billion in annual economic benefits of coral reefs, these reports and the policy actions that they will inform are critical to our American Blue Economy,” said retired Navy Rear Adm. Tim Gallaudet, Ph.D., assistant secretary of commerce for oceans and atmosphere and deputy NOAA administrator.

Coral reefs near higher density human populations are degraded, which is likely due to local stressors including land-based sources of pollution and damaging impacts from fishing.

“To conserve and restore coral reefs, we need to understand the overall condition of these  ecosystems,” said Jennifer Koss, director of NOAA’s Coral Reef Conservation Program. “This report represents a snapshot of reef condition and is a great resource for communities and decision-makers throughout the nation. We hope the report starts a dialogue about the various factors and potential solutions to the threats affecting coral reefs.”

Greatest among the threats to coral reefs is climate change, according to the report. Warmer, more acidic seawater is negatively affecting coral reefs globally, no matter how remote they are.

“These status reports clearly show the impacts people are having on coral reef ecosystems,” said Heath Kelsey, director of UMCES’s Integration and Application Network. “Our work in the Pacific and Atlantic Oceans shows a dire outlook for coral reef ecosystem health, from warming ocean waters, fishing, disease, and pollution from the land. Of all of these, climate change is the single biggest threat to shallow water coral reefs in the U.S., and worldwide.”

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?
