FOR IMMEDIATE RELEASE

 

Nov. 20, 2013

 

Tallahassee, FL.—Already pressured by a steady loss of habitat, many of Florida’s imperiled and iconic coastal waterbirds are vulnerable to declines in small fish that are necessary for their survival, according to a report by Audubon Florida and The Pew Charitable Trusts.

 

“Fins and Feathers: Why little fish are a big deal to Florida’s coastal waterbirdsexamines the crucial link between birds and the diverse array of small fish that are a critical food source. Declines in the populations of these fish, known alternatively as forage fish, prey fish or baitfish, could threaten imperiled birds such as Brown Pelicans, Roseate Spoonbills, Black Skimmers and Reddish Egrets, according to the report. 

 

“In Florida, our environment is directly linked to our quality of life and our economy,” said Julie Wraithmell, Audubon’s director of wildlife conservation. “This report shows how important baitfish are to Florida’s coastal birds, environment, communities and economy. Fisheries policy must consider the ecological and economic vitality that hinges on these smallest of fish.”

 

Few regulations limit the amount of forage fish such as sardines and herring that are hauled out of Florida’s coastal waters each year. Forage fish are used for bait, food and commercial products ranging from fertilizer to fish meal. Worldwide demand is growing. In 2012, seven main types of forage species, including sardines, scads, herrings, ballyhoo and mullet, accounted for 20 percent of all commercial catch off Florida. Commercial fishermen, for example, caught more than 9 million pounds of mullet that year, mostly for their eggs, which are sold around the world as a delicacy. 

 

Fishery managers can help conserve Florida’s forage fish and its natural resources by accounting for the needs of predators such as seabirds when setting fishing rules in Florida’s coastal waters. Bird conservation efforts historically have focused on other threats such as habitat loss, with less emphasis on ensuring prey abundance and availability. With many birds already pressured by a steady loss of habitat, this report reveals a new and critical conservation gap at a time when leaders can act before it’s too late.

 

The Florida Fish and Wildlife Conservation Commission has drafted species action plans for 60 bird species warranting protection. Among those species are 10 birds that rely on forage fish as part of their diet. Rules and permitting changes to protect these species will be completed in 2014; the plans and rules are slated for final adoption in Spring 2015.

 

The same state agency, which is meeting in Weston today and tomorrow, also has jurisdiction over fishing rules in nearshore waters extending up to 9 miles off the Gulf Coast and up to 3 miles off the Atlantic coast. Although the state has restricted the size and types of some fishing nets that typically snare small fish, a Tallahassee circuit judge ruled last month that the regulations are fundamentally unfair, ordering the state to stop enforcing them. Yet the restrictions—intended to implement a net ban approved by voters in 1994—will remain in effect while the state appeals the decision. 

 

All of these state efforts to protect small fish are critical to coastal wildlife.

 

“Small, nutrient-rich fish are the main course for many birds, marine animals and larger fish such as tarpon, snook  and sharks,” said Holly Binns, who directs Pew’s Southeast ocean conservation work. “It only makes sense to protect the smallest link in the ocean food webs. Investing in protections for forage fish will reap dividends down the line for fishermen, coastal communities, tourists and everyone who enjoys Florida’s birds and environment.”

 

In light of the report’s analysis, Audubon Florida and Pew encourage the state to:

 

·         Account for the forage needs of coastal waterbirds before expanding current forage fisheries or allowing the development of new forage fisheries.

 

·         Ensure sufficient abundance, variety, and sizes of forage fish species to meet the needs of coastal waterbirds and other marine wildlife when setting management limits on forage fisheries.

 

·         Identify and map foraging areas for nesting coastal waterbirds and areas subject to forage fisheries; analyze potential overlap of these areas and activities; and consider conservation and management options to avoid or minimize potential conflicts.

 

·         Protect forage fish habitat such as mangrove and seagrasses, as well as water quantity and quality in the estuaries.

 

 

 

Coastal development in Florida directly harms seagrass beds, mangrove forests and salt marshes, all of which serve as critical nursery habitat for forage fish. Similarly, changes in the quantity, quality and timing of freshwater that flows into estuaries threaten to degrade and diminish the quality of these important places for fish. At the same time, habitat loss and coastal development also pose risks to many of Florida’s bird populations.

 

Yet these birds and fish are crucial to an environment that draws tourists from around the world. Florida’s 2,276 miles of coastline are an international destination for wildlife viewing.

 

Residents and visitors to Florida who watch birds, dolphins, marine turtles and other species had an economic impact of $4.9 billion in 2011 alone, according to the most recent estimate from the state wildlife commission. In addition, the commission found that nearly 1 in 5 Florida residents participate in some form of wildlife viewing. Between 2006 and 2011, the number of people who visited Florida to view wildlife increased 22 percent.

 

“Florida’s birds are a delight for tourists and residents, yet they need help,” Binns said. “The state should recognize the importance of conserving forage fish for the sake of birds as well as other important marine life.”

Wildlife Promise: Artificial Reefs: Restoration Beyond Recreation?

Wildlife Promise

 

 


 

 

Posted: 19 Nov 2013 12:15 PM PST

 

Over the past few decades the five Gulf States have built artificial reefs both inshore and offshore with the aim of enhancing recreational fishing and diving opportunities. State and local governments on the Gulf Coast have expressed interest in creating additional artificial reefs with some of the money from the federal funds resulting from the BP oil disaster.

It is important to make sure these projects are funded appropriately and implemented using the best available science.

 

Artificial Reef Science: Are We There Yet?

 

A number of environmental and economic considerations should be considered when planning and designing new artificial reef projects. Water quality, wave interaction, bottom composition, reef profile, and materials used for construction are just a few things that can influence the effectiveness of these habitats, or potentially cause harm to adjacent habitats.

 

For a more comprehensive look at Gulf State artificial reef programs and key considerations in implementation or management, please take a look at NWF’s new white paper: Artificial Reefs of the Gulf of Mexico: A Review of Gulf State Programs & Key Considerations.

The bottom line is that scientists are still working to unravel the functionality of artificial reefs.  Some experts believe that artificial reefs can function comparably to natural reef communities. Others argue that artificial reefs merely attract existing fish from the adjacent open water habitat, forming more dense fish aggregations.  Only time, and additional research, will tell.

 

Natural Reefs vs. Artificial Reefs

 

Artificial reef projects are designed to enhance recreational fishing opportunities. Reef restoration projects are designed to restore the ecological functions provided by reef systems.  In cases where materials of similar type and size to historical or natural habitats-such as oyster reefs-are placed in nearshore waters in order to help the recovery of related ecological services, the term “artificial reef” is misleading. Because reef restoration projects can restore or replace “natural resources, habitats, or natural resource services” damaged by the Deepwater Horizon oil disaster, they may qualify as an appropriate use of Natural Resource Damage Assessment funding, or even other spill-related resources like the RESTORE Act and the National Fish & Wildlife Foundation Gulf Environmental Benefit Fund.

 

Loss of Human Use?

 

Artificial reefs develop communities of encrusting organisms and thus attract fish, but studies have shown that the communities that develop on artificial reefs remain quite different from those on natural reefs. Because artificial reef projects don’t serve to replace or restore the harm to natural resources, they have a more limited source of appropriate spill-related funding.

These types of projects could help to restore or replace the loss of human use stemming from the Deepwater Horizon disaster:

 

1.      The oil disaster resulted in significant closures of recreational fishing, boating and swimming ground. Scaled appropriately, artificial reefs could help compensate the public for lost access (or “human use”) to the Gulf of Mexico by generating new opportunities for angling, snorkeling, and engaging in other recreational activities.

 

2.      Artificial reef projects intended to restore or replace existing artificial reefs that were harmed during the oil disaster would be a justifiable use under the Natural Resources Damage Assessment process.

 

The Gulf of Mexico is an economic powerhouse and a national treasure. Natural and restored reef habitats can help make it whole again in the wake of the disaster. Strategic and appropriate investment of spill-related funding to restore its use, wildlife habitats, water quality and diversity of ecosystems will pay environmental and economic dividends for generations to come.

Coralations: COURT: Federal Government Must Protect Caribbean Coral Reefs, Better monitoring of fisheries required

A federal district court has ruled that the National Marine Fisheries Service violated the law by allowing fishing for depleted parrotfish and other algae-eating reef fish species without properly monitoring the fishery’s impacts on rare corals that depend on healthy fish populations. The decision came in response to an Endangered Species Act suit filed in January 2012 by Earthjustice on behalf of two conservation groups (CORALations and the Center for Biological Diversity), and Mary Adele Donnelly.  Local counsel for Earthjustice on this case was Miguel Sarriera, who has represented a number of groups battling for environmental protection throughout Puerto Rico.

The court determined the Fisheries Service must do a better job monitoring the effects of commercial fishing on elkhorn and staghorn coral in the U.S. Virgin Islands and Puerto Rico. These coral species are protected by the Endangered Species Act and serve as essential habitat for fish and other marine species.  Parrotfish protect these corals by grazing on algae that otherwise would smother the reef; removing the fish allows the algae to dominate reef systems and deny corals the space needed to grow.

In his decision Senior Judge Salvador E. Casellas ruled that the Fisheries Service’s monitoring plan was invalid because, as a baseline matter, the agency didn’t even know how many parrotfish were present to begin with and in any event had not committed to monitoring the impacts of the fishery on the parrotfish themselves. Under these circumstances, the court concluded the Service had illegally failed to establish  an adequate  procedure for verifying whether its fishing plan was preventing excessive harm to  the threatened elkhorn and staghorn corals.

“In the Caribbean, we have two big industries, fishing and tourism. Healthy coral reefs support both industries, but they have been dying for decades. Local communities are working with fishermen to successfully restore their reefs; farming corals on nurseries and transplanting them to natural reef in small protected areas,” said Mary Ann Lucking, CORALations. “The ruling compels government to revisit the failures of the balanced fishery management approach in general versus an ecosystem based approach, like community designated marine protected areas.”

“We are concerned that NMFS continues to open new fisheries without safeguards for protected species,” said Mary Adele Donnelly. “The court has demanded the Fisheries Service looks before leaping into yet another ecological disaster.”

“We know that corals face increasing threats from climate change and disease. Keeping a healthy, diverse population of algae-eaters on the reef is crucial to keeping coral reefs healthy,” said Andrea Treece, of Earthjustice.

“The corals in the Caribbean are dying – anyone can see it. This decision means that there will be enough parrotfish around for a healthy coral reef that could then become home for even more precious reef wildlife,” said Miyoko Sakashita, oceans director at the Center for Biological Diversity.

Parrotfish eat algae that can otherwise smother coral habitat.  U.S. Caribbean reefs already suffer from excessive algae cover, a situation exacerbated by scooping out the grazing fish necessary to hold back algal growth.  This situation leads to what scientists call a “death spiral” in which the removal of algae-eaters like parrotfish leads to increased algae and decreased coral, which in turn results in fewer fish and other reef creatures.

Not so long ago, elkhorn and staghorn corals were the main reef-building coral species in the Caribbean.  Yet these species have declined by as much as 98-99 percent since the 1970s thanks to stressors including overfishing, disease, and climate change.  As the corals decline, so does quality habitat for fish and other creatures.

Coral-list: Live Streaming Video of Coral Spawning in the Caymans

Dear Coral-List,

I wrote last month about the opportunity to see live-streaming footage of a coral spawning event near Grand Cayman Island via an underwater camera system maintained by the student-based nonprofit Teens4Oceans, local dive center Ocean Frontiers, online marine education organization Ocean Classrooms, and imaging company Wild Goose Imaging. We only witnessed minimal spawning last month, and are happy to share with you that an Orbicella (Montastrea) annularis colony in our viewing area began spawning around 10:07 PM CST last night and we have captured the event on our camera. We had over 3,000 viewers on our website for the show and they spawned right on time!

It is likely the coral will spawn again tonight at 9:15pm-ish MST (10:15pm-ish local time in Grand Cayman), and you can view it along with us, live, at http://teens4oceans.org/index.php/cayman-islands-reef-monitoring-webcam/.

To see footage from last night’s spawning event, watch this video clip, with the action starting around 1:57http://www.youtube.com/watch?v=V-JUWueJ5M8&feature=youtu.be

Cheers,
Erin Sams

Impactiq.org: Financing Sea Grass Restoration with Carbon Credits

Sea grass restoration helps halt erosion and arrest habitat loss. And sea grass meadows may also be one of best carbon investments around.

That suggests an economic model for seagrass restoration projects and a win-win for the oceans – by sequestering carbon, seagrass may slow ocean acidification.

The world’s seagrass meadows have declined significantly over the past century. Combined with mangrove forests, about one-third of the earlier global mass has been lost. Despite its efficiency in sequestering carbon, seagrass relies on slower clonal (versus sexual) reproduction.

In 2008, the Ocean Foundation began funding sea grass restoration projects around the US, mainly to repair damage caused by boats. Carbon sequestration was a secondary consideration for projects, behind erosion-control and habitat-protection.

The foundation found that seagrass, along with mangroves, take up considerable amounts of carbon. Indeed, scientists think that seagrass meadows take in and stores up to twice as much atmospheric carbon per acre than terrestrial forests.

So the foundation offers “Blue Carbon Offsets.” On the foundation’s SeaGrass Grow! website, donors can calculate their carbon footprint and sponsor seagrass planting as an offset. The offsets have raised about $80,000 so far.

For now, the program is voluntary, but the emergence of viable carbon markets in California and elsewhere creates the possibility of an income-generating, self-sustaining model. The foundation has partnered with Restore America’s Estuaries to certify aquatic vegetation carbon protocols, four for mangrove species and one for seagrass (eel grass).

Mark Spalding, president of the Ocean Foundation, says he expects to generate between $250,000 and $750,000 annually in the early years, as the market for such certificates develops. Certification in California is a year or two away, but once accepted, the protocols should meet the European criteria as well, he says.

“We really want to take this endeavor toward a paid offsets model,” Spalding says. “Right now carbon offsets are really associated with terrestrial forests, but the ocean is the number one carbon sink on the planet.”
