Cauliflower Coral Could Be Listed as Endangered

September 25, 2018 — Officials say endangered or threatened species protection may be warranted for cauliflower coral across its entire range — not just Hawaii.

The Hawaii Tribune-Herald reports the National Marine Fisheries Service issued last week its 90-day finding on a March petition seeking Endangered Species Act protection for the coral.

The coral, Pocillpora meandrina, is found in Hawaii and on most shallow reefs in the Indo-Pacific and Eastern Pacific. It has been devastated by habitat changes, disease and predation, lack of protection and other natural man-made factors.

The Center for Biological Diversity, which raised the petition, says in Hawaii alone, there was a 36.1 percent drop in coverage from 1999-2012.

Hawaiian Coral is considered for federal protection

September 20, 2018 — Hawaiian cauliflower coral is one step closer to federal protection under the Endangered Species Act, according to the first review released on Wednesday by the National Marine Fisheries Service of a manufacturing sponsor of the Center for Biodiversity.

Nickname cauliflower, Pocillopora meandrina is often pink, green or cream-colored and is characterized by its branching colonies. Called Ko? A on Hawaiian, the coral is rich in rocky reefs throughout the Indo-Pacific and East Pacific.

“Information presented in the production and other readily available information in our files shows that the most important threat to P. meandrina throughout its assortment at present and in the future, and to the coral columns in the Indo-Pacific region, such as P. meandrina is a part off, marine warming and subsequent warming-induced coral bleeding and mortality, says the report.

Between 2014 and 2015, cauliflower coral was one of many species affected by severe bleeding events, in which single-cell organisms called zooxanthellae that live inside the coral structure and give that pigment expelled. Zooxanthellae can resettle in the coral, other times the organism dies.

Subsequent investigations of Hanauma Bay on Oahu in 2016 recorded evidence of bleeding in 64 percent of P. meandrina colonies, while 1.3 percent were “affected by total post bleaching mortality”. On the western coast of Big Island, 49.6 percent of all living corals were leaks lost.

“Corrosion protection ultimately needs to reduce global temperature increases by drastically reducing fossil fuels. Cauliflower coral is also threatened locally through land-based contamination, sedimentation and physical disturbance caused by human activities, “says the Center for Biological Diversity in a Press Release.

Expanded protection of coral reefs in Gulf of Mexico may not be ready for approval until 2020

September 13, 2018 — A plan to expand the network of federally protected coral reef systems in the Gulf of Mexico may not be ready for approval by the Trump administration until early 2020, officials said Wednesday.

That means about five years will have passed since officials first began discussing in 2015 expanding the Flower Garden Banks National Marine Sanctuary, located about 100 miles off the coast of Galveston.

The sanctuary designation, which prevents over fishing and harassment of marine life in the area, currently stretches across 56 square miles, or three banks. In May, the sanctuary’s advisory council approved a proposal that would expand that area to 206 square miles, or 17 banks.

But officials have identified some potential tweaks. For example, the new plan actually would eliminate some of the protected area around Stetson Bank, one of the three current banks.

“There has not been a final decision how proceed,” sanctuary Superintendent G.P. Schmahl said during a Wednesday advisory council meeting, adding that officials likely would adjust the Stetson Bank boundaries.

According to the Flower Garden Banks website, there are several more steps to go in the process. For example, the National Oceanic and Atmospheric Administration, which oversees the 13 federally designated national marine sanctuaries, still must ask the Department of Interior to analyse the plan to understand how it will impact energy and mineral resource development.

Gulf’s deep-sea coral granted new protections by federal regulators

July 3, 2018 — Federal fisheries regulators have approved a plan granting new protections to some of the Gulf of Mexico’s oldest and most fragile stands of deep-sea coral.

The Gulf of Mexico Fishery Management Council unanimously voted to designate about 480 square miles as Habitat Areas of Particular Concern, a status that would make them a priority for conservation and scientific study. The protected areas are broken up into 21 sites, most off the Louisiana coast.

The council’s designations have been submitted to the National Marine Fisheries Service for review. Final approval is expected after a two-month public comment period.

Environmental groups had been lobbying for the protections for years. The Pew Charitable Trusts, which gathered 16,000 signatures in support, called the council’s decision “a major milestone” for critically important marine habitat.

Marine heatwaves are getting hotter, lasting longer and doing more damage

June 1, 2018 — On land, heatwaves can be deadly for humans and wildlife and can devastate crops and forests.

Unusually warm periods can also occur in the ocean. These can last for weeks or months, killing off kelp forests and corals, and producing other significant impacts on marine ecosystems, fishing and aquaculture industries.

Yet until recently, the formation, distribution and frequency of marine heatwaves had received little research attention.

Long-term change

Climate change is warming ocean waters and causing shifts in the distribution and abundance of seaweeds, corals, fish and other marine species. For example, tropical fish species are now commonly found in Sydney Harbour.

But these changes in ocean temperatures are not steady or even, and scientists have lacked the tools to define, synthesize and understand the global patterns of marine heatwaves and their biological impacts.

At a meeting in early 2015, we convened a group of scientists with expertise in atmospheric climatology, oceanography and ecology to form a marine heatwaves working group to develop a definition for the phenomenon: A prolonged period of unusually  at a particular location for that time of the year. Importantly, marine heatwaves can occur at any time of the year, summer or winter.

Scientists: Climate change could punish fish habitats targeted for conservation

May 8, 2018 — Aquatic preserves created to protect sea life from Australia to the ocean off Mayport stand to lose huge numbers of fish as oceans warm in coming decades, researchers reported Monday.

The report in the journal Nature Climate Change concludes many of more than 8,000 places labeled as marine protected areas will be overtaken by effects of climate change without major reductions in carbon-dioxide releases worldwide.

“There has been a lot of talk about establishing marine reserves to buy time while we figure out how to confront climate change,” said Rich Aronson, a researcher at the Florida Institute of Technology in Melbourne who co-authored the report with seven other scientists. “We’re out of time and the fact is we already know what to do: We have to control greenhouse gas emissions.”

Marine protected areas have grown mostly unnoticed over a generation, spreading to include big chunks of Florida’s coastline. The Oculina Bank, for example, a stretch of deep coral reefs near Vero Beach, was just a “habitat area of particular concern” when the South Atlantic Fisheries Management Council attached a label to it in 1984. Rules against anchoring and fishing for snapper and grouper were added in the 1990s, then in 2000 the size more than tripled and new restrictions were added.

New England Council adopts coral protection plan

February 28, 2018 — ELLSWORTH, Maine — After years of debate, the New England Fishery Management Council last month took final action on new rules aimed at protecting deep-sea coral from damage by fishing gear.

Meeting in Portsmouth, N.H., the council adopted its Omnibus Deep-Sea Coral Amendment and voted to submit the document to the National Marine Fisheries Service for review and approval.

Last June, the council adopted three coral protection zones in the Gulf of Maine. They are the area around Outer Schoodic Ridge southeast of the Schoodic Peninsula, the area around Mount Desert Rock, and the Jordan Basic Dedicated Habitat Research Area. This zone is roughly 40 square miles and located 50 miles offshore where the sea floor rises in a “bump” to a depth of about 208 meters or about 682 feet.

At its January meeting, the council approved a 600-meter (1,969-foot) minimum depth “broad zone” for the continental slope and canyons south of Georges Bank. Once the NMFS accepts the amendment, this entire zone — with one exception — will be closed to all fishing with any kind of bottom-tending gear, including both mobile equipment such as trawls or dredges dragged behind a boat and fixed gear such as traps, pots and gillnets. The council exempted gear used in the small but growing the Atlantic deep-sea red crab fishery.

The 600-meter minimum depth broad zone was one of several options considered by the council during its deliberations, Known as “Option 6” in the Coral Amendment, it was the council’s preferred alternative for protecting the continental slope and canyons prior to extensive public hearings last year. The council postponed taking final action last June so it could consider a proposal put forward by a coalition of environmental groups.

Known as “Option 7,” that proposal covered more of the ocean bottom, including shallower areas with depths ranging between 300 meters (984 feet) and 550 meters (1,804 feet). It, too, would have banned mobile gear but not fixed gear.

Deep-sea coral habitat south of Cape slated for protection

February 6, 2018 — The New England Fishery Management Council voted last week to protect deep-sea coral from the effects of fishing across a large stretch of ocean located about 100 miles south of Nantucket.

“The main reason why the council wanted to take this action and protect them from fishing is they are long-lived and very sensitive to disturbance. They can easily be broken and take a long time to recover,” said Michelle Bachman, who works for the council and is the group’s habitat plan development committee chairwoman. “We know they have a special ecological connection to other species like invertebrates and fish.”

Once approved by the National Marine Fisheries Service, the 25,153 square miles of ocean will join a 38,000-square-mile coral protection area off the Mid-Atlantic, and another protected area off the Southeastern U.S. covering, in total, nearly 100,000 square miles of the Atlantic continental shelf ecosystem.

Deep sea corals are found all over the world at depths of between around 130 to 10,000 feet. Most occur at between 1,000 and 2,600 feet, according to what Florida State University researcher Sandra Brooke told The Pew Charitable Trusts. They exist in a twilight – sometimes pitch black – world where photosynthesis isn’t possible. Northern coral don’t form reef structures, but include individual “plants,” fans, trees, that can be brightly colored, 10 feet across and live hundreds to thousands of years, growing slowly.

“Although the council could have chosen stronger protections, the measure marks a major expansion of coral habitat shielded from dredging and dragging,” said Peter Baker, who directs ocean conservation efforts in the Northeast for The Pew Charitable Trusts.

Few fishermen set pots or tow nets or dredges where coral live on the steep canyon walls that descend from the table top of Georges Bank, but even an accidental jostling by a lobster or crab pot or line or a misplaced tow could cause irrevocable damage. Fishermen told the council they didn’t tow gear below 1,600 feet; the measure protected coral below the 2,000-foot contour established by the New England council last week. The lone exemption was for the red crab fishery, which has relatively few participants, said Bachman.

NOAA: GARFO Releases 2017 Year in Review Report

February 2, 2018 — The following was released by NOAA Fisheries: 

The Greater Atlantic Regional Fisheries Office is proud to announce the release of our third annual Year in Review report.

In 2017, we continued to work toward our goals of sustainable use of living marine resources, conservation of the habitats upon which these resources depend, and the protection of endangered species and marine mammals.

In this report, we highlight some significant advances in conservation, such as finalizing the deep sea coral protection zones in the Mid-Atlantic, multiple successful projects to help fish get beyond barriers in rivers to spawn, and the designation of Atlantic sturgeon critical habitat. We helped save hundreds of sea turtles that had been trapped in the Gulf of Maine when water temperatures dropped, and we made good progress this year developing a system for storing fishery dependent data in a single database, which will greatly streamline the analysis of fish catches.

None of these accomplishments is ours alone. One of the keys to GARFO’s success is the dedication and commitment of our many partners. Indeed, one of the accomplishments of which we are most proud is our continued efforts to improve collaboration with our partner institutions.

We hope you will enjoy reading this short summary of GARFO’s highlights for the fiscal year 2017.

Marine biologist from the Meadowlands is restoring Florida’s coral

June 30, 2017 — Marine biologist David Vaughan and his team are reproducing coral in the lab and transplanting it along the coasts of Florida in a race against time as reefs are dying at an alarming rate. What would normally take 50 years to grow, his team can do in two or three years.

A former Rutherford resident, “Dr. Coral” earned his master’s at Farleigh Dickinson University in Rutherford and Ph.D at Rutgers in New Brunswick.

Vaughan studied Meadowlands’ ecology and grew algae to sustain shellfish at the Jersey Shore before embarking on an ambitious Florida coral reef restoration.

“At the time, we were just understanding the value of Meadowlands wetlands, but not the submerged Meadowlands,” Vaughan said.

Recruited to work for Mote Marine Laboratory in Florida, Vaughan taught clam aquaculture. His attention to coral grew as the disappearance of reefs progressed with climate change. Understanding coral’s complexity is key to addressing its plight.

Coral is a plant, animal, microbe and mineral, Vaughan notes.

“Coral is an animal that has a plant inside its tissue and microbial quality on outside, producing calcium carbonate,” Vaughan said. “It’s highly intolerant to temperature changes, needs to be in 72 to 78 degrees.”

As temperatures rise, the plant living inside coral starts to produce oxygen faster. The algae produces oxygen faster, coral gets lethargic because it can’t get rid of excess oxygen fast enough.
