OVERFISHING AND CORAL KILLING-SPONGES

FROM:  NATIONAL SCIENCE FOUNDATION 
Overfishing of Caribbean coral reefs favors coral-killing sponges
Caribbean-wide study shows protected coral reefs dominated by sponges with chemical defenses

Scientists had already demonstrated that overfishing removes angelfish and parrotfish that feed on sponges growing on coral reefs--sponges that sometimes smother the reefs. That research was conducted off Key Largo, Fla.

Now, new research by the same team of ecologists suggests that removing these predators by overfishing alters sponge communities across the Caribbean.

Results of the research, by Joseph Pawlik and Tse-Lynn Loh of the University of North Carolina Wilmington, are published this week in the journal Proceedings of the National Academy of Sciences (PNAS).

"In fact," says Pawlik, "healthy coral reefs need predatory fish--they keep sponge growth down."

The biologists studied 109 species of sponges at 69 Caribbean sites; the 10 most common species made up 51 percent of the sponge cover on the reefs.

"Sponges are now the main habitat-forming organisms on Caribbean coral reefs," says Pawlik.

Reefs in the Cayman Islands and Bonaire--designated as off-limits to fishing--mostly have slow-growing sponges that manufacture chemicals that taste bad to predatory fish.

Fish numbers are higher near these reefs. Predatory fish there feast on fast-growing, "chemically undefended" sponges. What's left? Only bad-tasting, but slow-growing, sponges.

Overfished reefs, such as those off Jamaica and Martinique, are dominated by fast-growing, better-tasting sponges. "The problem," says Pawlik, "is that there are too few fish around to eat them." So the sponges quickly take over the reefs.

"It's been a challenge for marine ecologists to show how chemical defenses influence the structure of ocean communities," says David Garrison, a program director in the National Science Foundation's (NSF) Division of Ocean Sciences, which funded the research.

"With this clever study, Pawlik and Loh demonstrate that having--or not having--chemical defenses structures sponge communities on Caribbean coral reefs."

The results support the need for marine protected areas to aid in coral reef recovery, believes Pawlik.

"Overfishing of Caribbean coral reefs, particularly by fish trapping, removes sponge predators," write Loh and Pawlik in their paper. "It's likely to result in greater competition for space between faster-growing palatable sponges and endangered reef-building corals."

The researchers also identified "the bad-tasting molecule used by the most common chemically-defended sponge species," says Pawlik. "It's a compound named fistularin 3."

Similar chemical compounds defend some plants from insects or grazers (deer, for example) in onshore ecosystems, "but the complexity of those ecosystems makes it difficult to detect the advantage of chemical defenses across large areas," says Pawlik.

When it comes to sponges, the view of what's happening is more direct, he says. "The possibility of being eaten by a fish may be the only thing a reef sponge has to worry about."

And what happens to reef sponges may be critical to the future of the Caribbean's corals.

Four Commercial Fishermen Indicted in Maryland for Illegal Harvest and Interstate Sale of Striped Bass from Chesapeake Bay

One Charged with Threatening Retaliation and Witnesses Tampering During Investigation

Four commercial fishermen and one company were indicted yesterday by a federal grand jury in Baltimore for a criminal conspiracy involving the illegal harvesting and interstate sale of striped bass on the Chesapeake Bay, announced Robert G. Dreher, Assistant Attorney General for the Justice Department’s Environment and Natural Resources Division, and Rod J. Rosenstein, U.S. Attorney for the District of Maryland.

According to court documents, Michael D. Hayden Jr., his company, William J. Lednum, Kent Sadler and Daniel Murphy engaged in a multi-year conspiracy during which time they harvested tens of thousands of pounds of striped bass on the Chesapeake Bay in violation of Maryland fishing regulations, falsified documents filed with the State of Maryland, and then transported and sold those poached fish in interstate commerce.   In addition, after the investigation of these crimes began, it is alleged that Hayden attempted to manipulate some witnesses’ testimony while trying to outright prevent the testimony and cooperation of others.   In addition, it is alleged that in at least one incident, Hayden threatened to retaliate against another potential witness he believed to be cooperating with investigators.   Hayden was arrested on Sept. 17, 2013, having been charged in a criminal complaint with several counts of witness intimidation and retaliation.

The 26-count indictment charges the defendants with conspiracy, and Lacey Act violations.    These charges carry possible terms of incarceration of five years.   In addition, the witness intimidation/retaliation charges against Mr. Hayden each carry a maximum-term of 20 years in prison.

An indictment is a charging document and all defendants are innocent until proven guilty.

This case is being investigated by criminal investigators with the Maryland Department of Natural Resources, Natural Resources Police and Special Agents from the U.S. Fish and Wildlife Service.   The case is being jointly prosecuted by the United States Attorney’s Office for the District of Maryland and the Environmental Crimes Section of the United States Department of Justice.

FIVE CHARTER FISHING CAPTAINS SENTENCED FOR ILLEGAL HARVESTING OF STRIPED BASS

Five Virginia Charter Fishing Boat Captains Sentenced for Lacey Act Violations
Nolan L. Agner, the last of five Virginia Beach charter fishing boat captains convicted of poaching Atlantic striped bass was sentenced today in federal court in Norfolk, Va.  All five captains – including Agner, Jeffery S. Adams, Raymond Carroll Webb, David Dwayne Scott, and William W. “Duby” Lowery IV – were sentenced for violating the Lacey Act by selling illegally-harvested striped bass, the Justice Department announced.

“As charter boat captains, these men had an obligation to know and follow the laws that protect this natural resource from overharvesting,” said Robert G. Dreher, Acting Assistant Attorney General for the Justice Department’s Environment and Natural Resources Division. “Their illegal poaching of striped bass gave them an unfair economic advantage over law abiding fisherman and irresponsibly posed a threat to this food supply.  “With these sentences, they will pay the price by serving jail time or receiving probation, as well as paying fines, surrendering their captain’s license, or having their operations closely monitored or curtailed.”

In 1984, Congress passed the Atlantic Striped Bass Conservation Act, recognizing that “Atlantic striped bass are of historic commercial and recreational importance and economic benefit to Atlantic coastal States and to the Nation,” and that it “is in the national interest to implement effective procedures and measures to provide for effective inter-jurisdictional conservation and management of this species.”  Since 1990, the Secretary of Commerce has imposed a moratorium on fishing for striped bass within the exclusive economic zone (EEZ), the zone where the U.S. and other coastal nations have jurisdiction over economic and resource management.  The moratorium makes it unlawful to fish for or harvest striped bass in the EEZ.  The moratorium also makes it unlawful to retain any striped bass that were taken in or from the EEZ.

The Lacey Act makes it unlawful for any person to import, export, transport, sell, receive, acquire or purchase any fish or wildlife taken, possessed, transported or sold in violation of any law or regulation of the United States, or to attempt to do so.  Such conduct constitutes a felony crime if the market value of the fish or wildlife is in excess of $350.  Under the Lacey Act, it is a “sale” of fish or wildlife for any person, for money or other consideration, to offer or provide guiding, outfitting, or other services.

Each of the captains, all of whom operated charters out of Rudee Inlet in Virginia Beach, was charged separately on Nov. 8, 2012, with violating the Lacey Act by selling charter fishing trips to harvest striped bass illegally from the EEZ, among other charges.

Today, Agner, captain of the Flat Line, having previously pleaded guilty to violating the Lacey Act, was sentenced to pay a $3,500 fine.  He and his corporation, Agner, Inc., were also placed on three years’ probation with special conditions requiring them to purchase and maintain a Vessel Monitoring System (VMS) device on any vessel that they own or operate for fishing purposes during the term of probation.
 
The other four defendants all previously pleaded guilty to violating the Lacey Act and have been sentenced:

On, April 25, 2013, Scott, captain of the Stoney’s Kingfisher, was sentenced to a $5,600 fine and $1,900 in restitution to the National Oceanic and Atmospheric Administration (NOAA).  Scott was also sentenced to three years’ probation with special conditions prohibiting Scott from engaging in either the charter or commercial fishing industries, anywhere in the world, in any capacity, during the term of his probation.  Scott is prohibited not only from captaining a vessel, but also rendering any assistance, support, or other services, with or without compensation, for other charter or commercial fishermen.

Also on April 25, 2013, Adams, captain of the Providence II, and his corporation Adams Fishing Adventures, were sentenced to three years’ probation with special conditions requiring them to apply for and receive a Federal Fisheries permit, and to purchase and install a VMS device on any vessel that they own or operate during the term of probation.

On May 30, 2013, Lowery, captain of the Anna Lynn, was sentenced to 30 days’ in jail, followed by 12 months of supervised release with the special conditions that Lowery surrender his captain’s license to the U.S. Coast Guard and that he not be eligible for reinstatement of that license.  Lowery is also prohibited from engaging in the charter fishing industry in any capacity during the term of his supervised release.

 On July 2, 2013, Webb, captain of the Spider Webb, and his corporation Peake Enterprises were sentenced to pay a $3,000 fine and $1,000 restitution to NOAA.  Webb and Peake Enterprises were also sentenced to three years’ probation with special conditions requiring them to apply for and receive a Federal Fisheries permit, and to purchase and install a VMS device on any vessel that they own or operate during the term of probation.

This case was investigated by NOAA’s Office of Law Enforcement and the Virginia Marine Police with assistance from the Federal Communications Commission Enforcement Bureau, Norfolk Office.  Assistant U.S. Attorney Stephen W. Haynie of the United States Attorney’s Office for the Eastern District of Virginia and Trial Attorney James B. Nelson of the Department of Justice’s Environmental Crimes Section of the Environment and Natural Resources Division prosecuted the case on behalf of the United States.
