Acoustic research breakthroughs could help inform conservation efforts

By Summit Voice

FRISCO — Breakthrough software is enabling scientists to better analyze humpback whale songs. For the first time, researchers have provided the a detailed description linking humpback whale movements to acoustic behavior on a feeding ground in the Northwest Atlantic.

“We have monitored and acoustically recorded whale sounds for years, and are now able to ‘mine’ these data using new computer software applications and methods, “ said Sofie Van Parijs, who heads the passive acoustics group at the Woods Hole Laboratory of NOAA’s Northeast Fisheries Science Center.

SUMMIT COUNTY — California’s drift gillnet fishery may be classified as one of the most deadly to marine mammals, the National Marine Fisheries Service said this week, announcing its proposed list of fisheries classifications in the Federal Register as required by the Marine Mammal Protection Act.

According to federal biologists, more than three sperm whales die inadvertently each year after being entangled in the drifting nets along with other non-target species like sharks, turtles, dolphins and sea lions. The loss of sperm whales isn’t sustainable considering the small overall population, according to the proposed listing. (more…)

SUMMIT COUNTY — With pirate fishing continuing to decimate global fish stocks, Interpol’s Environmental Crime Programme, with support from The Pew Charitable Trusts, the Norwegian Ministry of Foreign Affairs and the Norwegian Agency for Development Cooperation, is launching a major investigation aimed at curbing illegal fishing.

Illegal, unregulated and unreported fishing costs the global economy up to $23 billion a year, according to a study published in 2009 in the peer-reviewed journal PLoS One. Coastal communities, legal commercial fishing interests and the marine environment pay the price when illegal fishers exploit weak laws, poor information-sharing across jurisdictions and a shortage of monitoring and enforcement resources, particularly in developing countries.

A new analysis shows where China catches its fish.

By Summit Voice

SUMMIT COUNTY — Illegal fishing is a persistent problem, but it appears that China has elevated it to a new level, catching about 12 times more fish than it formally reports to the United Nation’s Food and Agriculture Organization, an international agency that keeps track of global fisheries catches.

Overall, Chinese fishing boats catch about US$11.5 billion worth of fish from beyond their country’s own waters each year according to a new study led by fisheries scientists at the University of British Columbia.

“China hasn’t been forthcoming about its fisheries catches,” said Dirk Zeller, a senior research fellow with UBC’s Sea Around Us Project and the study’s co-author. “While not reporting catches doesn’t necessarily mean the fishing is illegal … we simply don’t know for sure as this information just isn’t available,” Zeller said, explaining that there could be agreements between China and other countries that allow unreported fishing.

Biodiversity: More protection for manta rays?

CITES considering new regulations on international trade

FRISCO — With many hark and ray species threatened with extinction as a result of directed fishing and unintentional fisheries bycatch, the United States, Brazil, Ecuador, and more than 30 other countries have proposed to list several shark and ray species under the Convention on International Trade in Endangered Species.

CITES is meeting this week in Bangkok to consider global conservation policy and will consider regulations on international trade for the oceanic whitetip shark, porbeagle shark, three species of hammerhead shark, and two species of manta ray. Another species, the freshwater sawfish, is proposed for up-listing to a status that prohibits commercial international trade completely.

Pressure on the species is driven by the high demand for their fins, meat and gill rakers — used in shark fin soup and other dishes.

Conservation groups acknowledged U.S. leadership on the issue, explaining that many sharks and rays need more protection to survive.

“We commend the leadership of the United States and other government sponsors in requesting these essential measures to control and monitor international trade in these shark and ray species, and we implore other governments to vote in their favor,” said Dr. Cristián Samper, president and CEO of the Wildlife Conservation Society. “These taxa have suffered alarming declines from unregulated or insufficiently regulated fisheries and are in high demand for international commercial markets. There is a desperate need for trade controls to manage that demand and its impact on these vulnerable fishes.”

The proposals under consideration will significantly increase the number of sharks and rays that are regulated under CITES: currently, only a few of shark and ray species—the whale shark, basking shark, great white shark, and seven sawfishes—are listed. In order to be adopted, the proposals need approval from two-thirds of the governments voting.

“CITES listings for these species would help put controls on an international trade that threatens many shark species and the livelihoods that depend on them,” said Dr. Elizabeth Bennett, vice president of WCS’s Species Program and leader of the WCS CITES delegation.

Unlike many bony fish species, most cartilaginous fishes are long-lived, late-to-mature, and produce few young, making them vulnerable to over-fishing and their populations slow to recover once depleted.

“Demand for shark fins—the prime ingredient in shark fin soup— and gill rakers from manta rays is driving legal and illegal shark and ray fishing beyond what is sustainable, with estimates of tens of millions of animals killed annually to supply these trades, “said Dr. Rachel Graham, director of WCS’s Gulf and Caribbean Sharks and Rays Program. “Listing under CITES will provide a much-needed framework to monitor and regulate these heavily traded and highly sought-after species.”

WCS is committed to saving sharks and rays as part of a global commitment to promote recovery of depleted and threatened populations of marine species, halt the decline of fragile marine ecosystems, and improve the livelihoods and resilience of coastal communities throughout the world’s oceans.

 

Oceans: NOAA report flags illegal fishing by 10 countries

The foreign fishing vessel Marshalls 201 runs from the U.S. Coast Guard Cutter Walnut in September 2006 while still in U.S. waters. After the vessel was stopped and boarded, U.S. Coast Guard personnel determined the Marshalls 201 did not possess the proper permits to fish within U.S. waters and contained approximately 500 metric tons of tuna on board. The vessel and catch were seized and escorted to Guam for prosecution. The owner pled to one count and paid a penalty of $500,000.

Upcoming talks aimed at spurring compliance with treaties

By Summit Voice

SUMMIT COUNTY — As many global fish populations plunge due to unsustainable fishing practices, including illegal catch that ends up in U.S. grocery stores, the federal government  last week announced some small steps to try and curb those practices.

Last week, NOAA submitted a report identifying 10 nations whose fishing vessels engaged in illegal, unreported, and unregulated fishing, or had ineffective measures to prevent the unintended catch of protected species in 2012: Colombia, Ecuador, Ghana, Italy, Mexico, Panama, the Republic of Korea, Spain, Tanzania, and Venezuela.

The U.S. will soon start consultations with those countries to encourage them to take action to address unauthorized fishing and bycatch by their fishermen. Mexico was also identified for ineffective management of the bycatch of North Pacific loggerhead sea turtles, which travel between Japan and Mexico through Hawaiian waters, and are endangered under the U.S. Endangered Species Act.

All 10 nations identified in this year’s report had vessels that did not comply in 2011 and/or 2012 with conservation and management measures required under a regional fishery management organization.

“As one of the largest importers of seafood in the world, the United States has a global responsibility and an economic duty to ensure the fish we import is caught sustainably and legally,” said Sam Rauch, deputy assistant administrator for NOAA’s Fisheries Service. “We look forward to working with these nations to encourage their compliance, and we will continue to work with our partners to detect and combat illegal practices.”

“NOAA’s international fisheries work is critical to the economic viability of U.S. fishing communities and the protection of U.S. jobs,” said Russell Smith, NOAA deputy assistant secretary for international fisheries. “This is about leveling the playing field for fishermen around the world, and IUU fishing represents one of the biggest threats to the U.S. fishing industry. Seafood is a global business, and U.S. fishermen following the rules should not have to compete with those using illegal or unsustainable fishing practices,” Smith said.

According to NOAA, unauthorized and illegal fishing undermines international efforts to sustainably manage and rebuild fisheries and creates unfair market competition for fishermen who adhere to strict conservation measures, like those in the United States. Illegal fishing can devastate fish populations and their productive marine habitats, threatening food security and economic stability. Independent experts have estimated economic losses worldwide from illegal fishing at between $10 billion and $23 billion annually.

All six of the nations identified in the previous 2011 Biennial Report to Congress (Colombia, Ecuador, Italy, Panama, Portugal, and Venezuela) have addressed the instances by taking strong actions like sanctioning vessels, adopting or amending laws and regulations, or improving monitoring and enforcement. Each of these six nations now has a positive certification for their 2011 identified activities. However, a nation positively certified for action taken since the last report may be listed again as engaged in IUU fishing if new issues are identified, as is the case in this report.

If a nation fails to take appropriate action to address the instances of illegal fishing or bycatch activities described in the report, that nation’s fishing vessels may be denied entry into U.S. ports, and imports of certain fish or fish products from that nation into the United States may be prohibited. The United States is second only to China in the amount of seafood it imports. NOAA’s latest figures showed that 91 percent of the 4.7 billion pounds of seafood consumed in the United States in 2011 was imported.

66 coral species to get Endangered Species Act protection

Primary threats all linked to greenhouse gases and global warming

FRISCO — Federal scientists say that at least 66 species of coral in the Caribbean and Pacific are in danger of going extinct because of threats linked to global warming caused by greenhouse gas emissions.

Announcing a proposal to list those species under the Endangered Species Act, the National Oceanic and Atmospheric Administration identified 19 specific threats including rising ocean temperatures, ocean acidification, disease, ecological effects of fishing, and poor land-use practices. NOAA scientists said three of the major threats — rising ocean temperatures, ocean acidification, and disease — are all directly or indirectly linked to greenhouse gas emissions and a changing climate.

In the Pacific, seven species would be listed as endangered and 52 as threatened. In the Caribbean, five would be listed as endangered and two as threatened. Two other Caribbean species — elkhorn and staghorn corals — would be reclassified from threatened to endangered. (more…)

Biodiversity: Crucial meeting for bluefin tuna conservation

Environmental groups urge strict catch limits

By Summit Voice

SUMMIT COUNTY — This week’s meeting of the International Commission for the Conservation of Atlantic Tuna could be crucial for some species, as the group, gathering in Morocco, will decide on on  future bluefin tuna catch limits.

Bluefin tuna are already under extreme pressure from overfishing, and some countries — notably Spain — are pushing for higher, unsustainable catch limits. Conservation groups, including the Center for Biological Diversity, are calling on the delegates to put a cap on bluefin tuna fishing to preserve and restore the species in the Atlantic Basin.

Researcher document recovery in coral reef ecosystems of Dry Tortugas National Park

By Summit Voice

SUMMIT COUNTY — Focused and collaborative conservation efforts can pay off in coral reef ecosystems, federal biologists say, reporting that they’ve documented a resurgence of reef fish and corals in the Dry Tortugas National Park, located about 70 miles west of Key West.

NOAA established the Florida Keys National Marine Sanctuary in 2001, consisting of 151 square nautical miles of protected marine habitat. To monitor the progress of this protected area, which had suffered from overfishing and other environmental changes, the Cooperative Institute for Marine and Atmospheric Studies funded a marine census to examine how the ecosystem was responding after seven years as a protected area.

“We are very encouraged to see that stocks have slowly begun to recuperate since implementing ‘no-take’ marine protected areas in the region,” said Jerry Ault, chief scientist on the project and a professor of marine biology and fisheries at the University of Miami’s Rosenstiel School of Marine and Atmospheric Science. “We are currently crunching the data collected to see what adjustments may need to be made to help guide future management decisions to address the issues of biodiversity protection, restoration of ecological integrity, and fishery management.” (more…)

Marine resources still being degraded and exploited at an unsustainable rate

By Summit Voice

SUMMIT COUNTY — Listening to official government sources about the state of the world’s oceans is one thing, with a steady stream of “good” news often highlighting new marine reserves and the recovery of fisheries.

But on the whole, world leaders have made only “pitiful” progress in their promises to  protect global oceans from overfishing and other threats, according to the Zoological Society of London, which is hardly a hotbed of radical environmentalism. In fact, there has been little progress in meeting critical conservation goals in the past 20 years, the scientists wrote in a  study published June 15 in Science.

The researchers compared goals established at the World Summit on Sustainable Development in 2002. At the meeting, 192 countries agreed on targets for protecting vulnerable species and marine habitats and managing fishing sustainably in national waters.

Ten years on, none of these targets have been met, and in some cases the situation is worse than before, said the researchers with the zoological society, hardly known as a hotbed of radical environmentalism. (more…)
