Protect Local Shark Populations
Protect our Coastal Shark Population
As the summer fishing season begins, all anglers, sport and commercial, should consider the plight of declining shark populations and the effects that the heavy fishing of them is having on the ecosystem. Fewer big sharks in the oceans mean that bay scallops, oysters and other shellfish may be damaged, tying unlikely members of the marine ecosystem to the same fate. A study by Dalhousie University has found that over fishing the largest predatory sharks, such as the bull, blue, dusky, and hammerhead has led to the rapid expansion of ray, skate, and small shark prey species. Large sharks have been functionally eliminated from the east coast, no longer performing their ecosystem role as top predators. Fewer big sharks mean there are more of the fish they once ate, such as the Cownose ray.
With an average population increase of about eight percent per year, the east coast Cownose ray population may now number as many as 40 million. Cownose can grow to be more than four feet across, eat large quantities of bivalves, including bay scallops, oysters, soft-shell and hard clams in the bays and estuaries they use for habitat in the summer and spring. This increased predation by cownose rays inhibits the recovery of oysters and clams which are already damaged by overexploitation, disease, habitat destruction, and pollution. By 2004, Cownose rays had completely devastated North Carolina’s scallop population, collapsing a centuries-old fishery.
As many as 73 million sharks are killed worldwide each year for the finning trade, and the number is rising. Growing demand for shark fins and meat has led to increased fishing, but a large number are caught accidentally as "by catch" by fisherman after other types of fish. According to Carl Safina of Blue Ocean Institute, 75% of all fish are captured as by catch. The danger for Sharks (and other elasmobranches) posed by increased fishing pressure, is that they are long-lived, slow to mature, and produce few offspring. Aggressive fishing can take a toll much more quickly on sharks than other fish.
Ecologists have long held that maintaining the populations of top predators is critical for sustaining healthy oceanic ecosystems; its organisms are interconnected, and changes at one level have implications at others. An Ecosystem based view of fisheries management states the necessity of protecting species such as sharks as a primary player in the overall health of the ecosystem.
But, sharks are also a protected species. The Shark Finning Prohibition Act was signed into law on December 21, 2000. The Act prohibits people under U.S. jurisdiction from: (1) engaging in shark finning at sea; (2) possessing shark fins aboard a fishing vessel without the corresponding carcass; or (3) landing shark fins without the corresponding carcass. And according to NOAA’s Regulatory Changes in Amendment 1 to the Fishery Management Plan for Atlantic Tunas, Swordfish, and Sharks, several species of pelagic and coastal sharks are protected by Time and Area Closures for commercial vessels with bottom longline gear on board from January through July off North Carolina.
A map of the closed shark areas can be found at: http://www.nmfs.noaa.gov/sfa/hms/images/HMS_Closed_Areas_w_Bathymetry.jpg
Yet, without increased enforcement of existing regulations, big sharks may be fished to extinction. As sportsman, waterman, and stewards of our oceans, it is our duty to protect our Living Marine Resources and report violations. To help engage the public, the NOAA Office of Law Enforcement adopted COPPS (Community Oriented Policing and Problem Solving) as a national initiative, designed to empower communities and individuals to actively participate in their local marine conservation management. The NOAA Fisheries Enforcement Hotline (1-800-853-1964) provides live operator coverage 24 hours a day, 7 days a week for anyone in the United States to report a federal fisheries violation.
I know it’s difficult to worry about the fate of sharks, but losing these top predators is having a devastating effect on our home waters, damaging the already fragile shell fish habitats and sea grass. This summer, a catch and release policy for sharks should be in every angler’s toolbox. Also, be on the lookout for illegal fishing activities. Sharks matter, so please report any and all violations to the NOAA COPS hotline at 1-800-853-1964.

NOAA publishes final rule on IUU Fishing
NOAA Fisheries has published a final rule to define the term "illegal, unreported or unregulated (IUU) fishing", as required by section 403 of the Magnuson-Stevens Fishery Conservation and Management Reauthorization Act of 2006. For purposes of the Act, this final rule defines "illegal, unreported, or unregulated'' fishing as:
(A) fishing activities that violate conservation and management measures required under an international fishery management agreement to which the United States is a party, including catch limits or quotas, capacity restrictions, and bycatch reduction requirements; (B) overfishing of fish stocks shared by the United States, for which there are no applicable international conservation or management measures or in areas with no applicable international fishery management organization or agreement, that has adverse impacts on such stocks; or (C) fishing activity that has an adverse impact on seamounts, hydrothermal vents, and cold water corals located beyond national jurisdiction, for which there are no applicable conservation or management measures or in areas with no applicable international fishery management organization or agreement.

Sharks functionally extinct: from CBC news
The overfishing of large shark species off the eastern seaboard of the United States has upset the balance of marine life, a team of Canadian and U.S. scientists says.
"We're chopping off the top of the food chain," said Julia Baum of Dalhousie University in Halifax, co-author of a study outlining the huge decline in big sharks over 35 years.
Overfishing of several species of sharks, including hammerheads, is causing a dangerous ripple effect through the marine food chain, a new study says.Overfishing of several species of sharks, including hammerheads, is causing a dangerous ripple effect through the marine food chain, a new study says.

Fewer big sharks mean there are more of the fish they once ate, such as the cownose ray.
The population of the rays in Chesapeake Bay has grown by 20 times in 30 years, said Charles Peterson, a professor of marine sciences at the University of North Carolina at Chapel Hill and co-leader of a study published in Science on Friday.
As the rays increase — they may now number 40 million — they have slashed the populations of bay scallops, oysters and soft-shell and hard clams, Baum said. The century-old bay-scallop fishery is now just a memory.
So many sharks have been killed that they are "functionally extinct," which means they can no longer perform their role of controlling middle predators in the marine ecosystem, Baum told CBC News.
The population imbalance shouldn't be a surprise considering the drop in large sharks in recent decades. While they are fished to meet the growing demand for shark fins and meat, the single largest problem is the sharks taken accidentally as "bycatch" by fishermen seeking other species, she said.
As many as 73 million sharks are killed worldwide each year for their fins, and the number is rising rapidly.
The new study, funded by the Pew Institute for Ocean Science, updated a 2003 study by Baum and noted Dalhousie fisheries biologist Ransom A. Myers, who died recently.
The new study concluded that the original estimates of declines in big sharks had been too conservative.
Populations plunge
Now the population of scalloped hammerhead and tiger sharks may have fallen by more than 97 per cent since 1970, while bull, dusky and smooth hammerhead sharks are down by more than 99 per cent.
As the shark populations fell, the fish they once ate boomed and the marine life at the bottom of the food chain — scallops, shrimp, clams — have been ravaged.
The rise of the cownose ray is even affecting the underwater vegetation.
"They're known in the Chesapeake Bay, in their great schools, to excavate and denude large areas of sea grass," Peterson said.
Increased protection for great sharks, including reduced fishing of all shark species and enforcing bans on shark finning, is needed to rebalance the system, Baum said.

Green Peace Pirate Fishing Blacklist
View the Blacklist here
Greenpeace has compiled this database from existing official registries of Illegal, Unregulated and Unreported (IUU) vessels and companies. Industrial fishing vessels and fishery support vessels, including motherships, refrigerated carriers and supply vessels, may be included on the database. The purpose of this blacklisted vessels and company database is to provide a single database tool with convenient search functions for national fisheries administrators, particularly from developing countries, and others to quickly check on the compliance status of foreign vessels trying to unload its catch in port, seeking services in port, seeking a fishing license or to register or flag in a country. It is also hoped that the database will serve as tool for retailers and suppliers to ensure the fish they source do not come from pirate fishing vessels or from companies involved in such activities. At a later stage the database will also hold information of irresponsible fishing vessels and companies that fish without a license or are in breach of management and conservation measures that Greenpeace comes across during it’s time at sea or in monitoring well known ports of illegal fish landings, or is reported from other reliable sources. It is hoped that this information will further assist authorities to deal adequately and in timely and efficient manner with pirate fishing.

VIMS finds worldwide problem with Ocean Seagrass
After more than 30 years of studying Chesapeake Bay seagrasses, Virginia Institute of Marine Science researcher Dr. Robert Orth is well aware that this vital resource is in serious trouble, beset by a host of ills including excess nutrients, turbid water, and a warming climate.
Now, a new study by Orth and an international group of colleagues reveals what may be the most troublesome finding of all: the seagrass problem is global, yet the public remains largely unaware of its scope and significance.
The study, which appears in the December issue of BioScience, was conducted by Orth and 12 other members of the Global Seagrass Trajectories Working Group, part of a national effort to promote the analysis and synthesis of ecological information.

NOAA releases Cooperative Research DVD
NOAA Fisheries has produced a new DVD, In Good Company , that describes recent activities of the Cooperative Research Partners Program. This DVD includes exciting on-the-water footage, as well as interviews with fishermen and scientists who have participated in the program. In recent years, commercial and recreational fishermen have become more involved in fisheries research throughout the Northeast Region, lending their unique perspective and technical expertise to the scientific process. The mission of the Cooperative Research Partners Program is to guide the management of fishery resources in New England by building cooperative relationships among industry, scientists and managers.
Several recent studies are profiled in the DVD. The development of a rope separator trawl allows fishermen to capture healthy populations of haddock, while allowing overfished cod to escape through a specially designed net. Another project is exploring the impacts of bottom trawling in the Western Gulf of Maine, by comparing the quality of seafloor habitat in open and closed areas. An industry-based survey of cod in the Gulf of Maine is evaluating the importance of inshore areas as nursery and spawning grounds. Recreational and commercial fishermen have tagged more than 114,000 cod; these data are being used to assess migration patterns and collect growth information for stock assessments.
Through the Cooperative Research Partners Program, Federal, state, academic, and private partners are working together in real-life settings to set research priorities, collect and analyze data, and discuss scientific findings. Scientists benefit from increased time at sea and the opportunity to gain local knowledge from fishermen, while captains are compensated for the use of their vessel through monetary payments or the sale of their catch. These cooperative projects have demonstrated success in improving relationships and building a foundation of trust in fisheries science.

NOAA Prohibition on Grouper
A seasonal prohibition on fishing for or possession of red, black, tiger, yellowfin, or yellowedge grouper (Grouper Unit 4) in Caribbean federal waters will be in effect from 12:01 a.m., local time, February 1 through April 30, 2007 . Caribbean federal waters are those waters extending to 200 nautical miles offshore from the nine-mile seaward boundary of the Commonwealth of Puerto Rico and the three-mile seaward boundary of the territory of the U.S. Virgin Islands. This prohibition on possession does not apply to grouper that are harvested and landed ashore prior to the closure.
Also, from February 1 through April 30 each year no person may fish for or possess any species of fish, except highly migratory species, within the Grammanik Bank closed area. An annual spawning aggregation of yellowfin grouper has been documented at Grammanik Bank, south of St. Thomas , occurring from about February through April each year. This closure is designed to address overfishing and protect the yellowfin grouper spawning aggregation. The term “fish” includes finfish, mollusks, crustaceans, and all other forms of marine animal and plant life other than marine mammals and birds. Highly migratory species refers to bluefin, bigeye, yellowfin, albacore, and skipjack tunas; swordfish; sharks; white marlin, blue marlin, sailfish, and longbill spearfish.
For more information, read the fishery bulletin.

New England Shellfish Areas Closed due to Red Tide
On October 18, 2005, at the request of the U.S. Food and Drug Administration (FDA), NOAA Fisheries took emergency action to close certain New England waters due to the presence of a toxin that causes paralytic shellfish poisoning. The FDA has recently renewed this recommendation based on current oceanographic conditions and alga sampling data. These data suggest that the northern section of the Temporary Paralytic Shellfish Poison Closure Area should remain closed to the harvest of bivalve molluscan shellfish, and that the southern area should remain closed to the harvest of whole or roe-on scallops. Therefore, a new temporary rule has extended these closures through June 30, 2007. A map of the affected area is available online.
