Scientists find early facial features on ancient fish

Scientists have found the most primitive creature to have had a face like humans, and there’s definitely something fishy about it.

This first face belongs to the newfound species Entelognathus primordialis, “primordial complete-jaw,” an armored fish that plied the seas nearly 420 million years ago. Related fish from that period had simple jaws made mostly of cartilage. But Entelognathus had a complex jaw, knit together from many bony plates like those found in the jaws of humans and dogs and thousands of other living animals with backbones. That strangely modern jaw — stuck on an otherwise primitive body — gives it what could be called the earliest known modern face.

“This is like finding the nose of a space shuttle in a hay wagon from the Middle Ages,” paleontologist Xiaobo Yu of Kean University in New Jersey, one of the researchers responsible for the new find, says via e-mail. The new fish is also contributing to a major upheaval in scientists’ understanding of the base of the family tree that spawned rattlesnakes and guppies and penguins and, eventually, Homo sapiens.

The first Entelognathus fossil was unearthed in China in 2010, but it was not until scientists had chipped away at the specimen in the lab that they realized they were onto something very weird. Their new fish looked like a placoderm, an ancient swimmer girded in homegrown armor made of bony plates. The fish, described in this week’s issue of Nature, had small, almost immobile eyes and a flat forehead. And then there was its lower face: a jigsaw puzzle of interlocking bones a lot like humans. It’s a homely ancient fish with a supermodel’s bone structure.

Federal Agencies including Park Service Drop Private Certification Requirements for “Sustainable Seafood”; Will use NOAA FishWatch

WASHINGTON (Saving Seafood) September 25, 2013 — Both the National Park Service (NPS) and the General Services Administration (GSA) have changed their “sustainable seafood” guidelines to focus on data from NOAA FishWatch instead of third-party ratings and certifications from the Marine Stewardship Council (MSC) and the Monterey Bay Aquarium’s Seafood Watch program.

The GSA, a federal agency that supplies food to other government agencies, has updated their “Heath and Sustainability Guidelines” to be in accordance with NOAA’s federal sustainability data. Previously, the guidelines instructed vendors to “only offer fish/seafood identified as ‘Best Choices’ or ‘Good Alternatives’ on the Monterey Bay Aquarium’s Seafood Watch list or certified by the Marine Stewardship Council.”

The Agency’s seafood sustainability standards are modified in the guideline’s footnotes. Footnote 44 and footnote 44* indicate a clear change from their previous policy:

44. Examples of “Best Choices” do not imply government endorsement of these standards. Only endorsements made directly by governing agencies (e.g., USDA, FDA) should be considered government endorsements.

44.* The NOAA FishWatch Program defines sustainable seafood as “catching or farming seafood responsibly, with consideration for the long-term health of the environment and the livelihoods of the people that depend upon the environment.” Verifying the health and sustainability of U.S. and international fisheries is not always simple. Domestic fisheries are managed by State and Federal agencies under legally established fisheries management plans. International fisheries are managed under sovereign laws and international treaties. Guidance on how to make sustainable seafood choices is found on the NOAA FishWatch site at: www.fishwatch.gov/buying_seafood/choosing_sustainable.htm.

FDA says US, imported seafood has no radiation risk from Fukushima

SEAFOOD.COM NEWS by John Sackton Sept. 23, 2013 – In a September update on food safety issues related to the Fukushima nuclear disaster, the FDA declared that there is no public health concern for the U.S. They said that the same holds true for imported seafood, including seafood from Japan. For example, in a study that detected very low levels of cesium in bluefin tuna caught off the coast of California, the FDA says these levels were 300 times lower than the level that would even trigger an investigation to see if there was a public health concern. In short, although some specific radioactive isotopes may be detected from time to time, the FDA says that these levels are so low as to provide no issue whatsoever for public health.

Their full statement is below:

To date, FDA has no evidence that radionuclides from the Fukushima incident are present in the U.S. food supply at levels that would pose a public health concern. This is true for both FDA-regulated food products imported from Japan and U.S. domestic food products, including seafood caught off the coast of the United States.

Consequently, FDA is not advising consumers to alter their consumption of specific foods imported from Japan or domestically produced foods, including seafood. FDA continues to closely monitor the situation at and around the Fukushima Dai-ichi facility, as it has since the start of the incident and will coordinate with other Federal and state agencies as necessary, standing ready to take action if needed, to ensure the safety of food in the U.S. marketplace.

Import Alert # 99-33, which instructs FDA field personnel to detain foods shipments from Japan if the food is likely to contain radionuclide contamination, remains active. In addition, FDA tests for radionuclides as part of its routine surveillance, through the toxic elements in food and foodware monitoring program and through its Total Diet Study.

On top of the information obtained from its testing of imported and domestic foods, FDA stays current on radiation monitoring efforts by other U.S. Government agencies, including the environmental radiation monitoring program (RadNet) conducted by the Environmental Protection Agency (EPA). Additionally, the Agency consults on a formal and informal basis with experts from government, academia and the private sector on radiation safety issues. FDA scientists also keep abreast of scientific publications and reports from both private and public scientific institutions, including oceanographic research institutions. For example, a study published in 2012 in the Proceedings of the National Academy of Sciences (PNAS) reported finding very low levels of Cesium in Pacific Bluefin tuna caught by recreational fisherman off the coast of California in August 2011. FDA reviewed this study and determined that the levels of cesium were roughly 300 times lower than levels that would prompt FDA to investigate further to determine if there were a health concern.

Small fish bring big menu opportunities

Despite their reputation as oily, smelly, fatty and usually packed in a tin, there’s lot to like about anchovies, sardines and smelt. They’re extremely flavorful, loaded with healthy omega-3s and abundant in our oceans. And while small fish are found most often on menus in Caesar salads, atop pizzas or inside sushi rolls, lately more chefs are using them in appetizers or entrees.

According to Datassential MenuTrends, 21 percent of all restaurant menus feature at least one variety of small fish, an increase of 2 percent since 2009. They can be found most often at fine-dining restaurants, where 36 percent of menus feature a small fish. Anchovies, appearing on 19 percent of menus, are the most common small fish offered by restaurants.

Their rarity on menus, along with and their distinct flavor, is precisely why chef Joe Realmuto loves to put anchovies, sardines and smelts on the menu at Nick & Toni’s East Hampton and Nick & Toni’s Café in New York City.

Fishermen now the “right hand” of marine research

Bycatch reduction, gear recovery and direct-seafood marketing are among the topics currently addressed through collaborative research with commercial and recreational fishermen.

Other projects examine rockfish populations within the Rockfish Conservation Areas; yellowtail movement patterns in Southern California, and spawning populations of night smelt along the North Coast.

All of the projects are unique in that fishermen are in some way directly involved with the research. They may have initiated the project’s basic concept, or they may be helping to collect data. In some cases, they are also helping analyze it. The unifying theme is that both anglers and commercial fishermen are engaged in work that often, previously has been isolated within academic or management circles.

California Sea Grant supports this innovative research through our partnership with the non-profit Collaborative Fisheries Research West, funded by the California Ocean Protection Council. California Sea Grant Extension specialists are lead investigators on several of the projects, as well.

The 12 projects listed below include both large, multi-year grants, with awards ranging from $206,000 to $242,000 plus matching funds, and mini grants, with awards at or below $25,000 plus matching funds.

VIDEO: Dr. Ray Hilborn on Federal Fisheries Management and Magnuson-Stevens Reauthorization

WASHINGTON (Saving Seafood) — September 17, 2013 — Last Wednesday, Dr. Ray Hilborn, of the University of Washington School of Aquatic and Fishery Sciences, testified before the House Committee on Natural Resources during a hearing on the reauthorization of the Magnuson-Stevens Fishery Conservation and Management Act. Following his testimony on Capitol Hill, in which he adhered to the Congressional hearing’s five minute time limit, Dr. Hilborn sat down with Saving Seafood’s Executive Director Bob Vanasse for an in-depth discussion of his recommendations, and to give his presentation in full.

Dr. Hilborn explains how an emphasis by fisheries managers on eliminating overfishing has led government agencies to ignore other important aspects of the Magnuson-Stevens Act, which mandate the protection of fisheries resources alongside concerns for the socio-economic well being of fishermen and their communities.

Dr. Hilborn aruges that  that the U.S. has largely “solved” the problems surrounding overfishing and that underutilization of the resource should be of greater concern to fisheries managers.

The video begins with Dr. Hilborn’s evaluation of U.S. fisheries policy under the Magnuson-Stevens Act, his recommendations for the reauthorization, and concludes with a question and answers.

Ocean acidification, the lesser-known twin of climate change, threatens to scramble marine life on a scale almost too big to fathom.

NORMANBY ISLAND, Papua New Guinea — Katharina Fabricius plunged from a dive boat into the Pacific Ocean of tomorrow.

She kicked through blue water until she spotted a ceramic tile attached to the bottom of a reef.

A year earlier, the ecologist from the Australian Institute of Marine Science had placed this small square near a fissure in the sea floor where gas bubbles up from the earth. She hoped the next generation of baby corals would settle on it and take root.

Fabricius yanked a knife from her ankle holster, unscrewed the plate and pulled it close. Even underwater the problem was clear. Tiles from healthy reefs nearby were covered with budding coral colonies in starbursts of red, yellow, pink and blue. This plate was coated with a filthy film of algae and fringed with hairy sprigs of seaweed.

Instead of a brilliant new coral reef, what sprouted here resembled a slimy lake bottom.

Isolating the cause was easy. Only one thing separated this spot from the lush tropical reefs a few hundred yards away.

Carbon dioxide.

In this volcanic region, pure CO2 escapes naturally through cracks in the ocean floor. The gas bubbles alter the water’s chemistry the same way rising CO2 from cars and power plants is quickly changing the marine world.

In fact, the water chemistry here is exactly what scientists predict most of the seas will be like in 60 to 80 years.

That makes this isolated splash of coral reef a chilling vision of our future oceans.

Movement of marine life follows speed and direction of climate change

Scientists expect climate change and warmer oceans to push the fish that people rely on for food and income into new territory. Predictions of where and when species will relocate, however, are based on broad expectations about how animals will move and have often not played out in nature. New research based at Princeton University shows that the trick to more precise forecasts is to follow local temperature changes.

The researchers report in the journal Science the first evidence that sea creatures consistently keep pace with “climate velocity,” or the speed and direction in which changes such as ocean temperature move. They compiled 43 years of data related to the movement of 128 million animals from 360 species living around North America, including commercial staples such as lobster, shrimp and cod. They found that 70 percent of shifts in animals’ depth and 74 percent of changes in latitude correlated with regional-scale fluctuations in ocean temperature.

“If we follow the temperature, which is easier to predict, that provides a method to predict where the species will be, too,” said first author Malin Pinsky, a former Princeton postdoctoral researcher in ecology and evolutionary biology who is now an assistant professor of ecology and evolution at Rutgers University.

“Climate changes at different rates and in different directions in different places,” he said. “Animals are basically being exposed to different changes in temperature.”

The researchers compiled survey data collected from 1968 to 2011 by American and Canadian fishery-research centers and government panels. The surveys recorded surface and bottom temperatures, as well as the complete mass of animals in nine areas central to North American fisheries: the Aleutian Islands; the eastern Bering Sea; the Gulf of Alaska; the West Coast from Washington to California; the Gulf Coast from Louisiana to Mexico; the Northeast coast from North Carolina to Maine; the coast of Nova Scotia; the southern Gulf of St. Lawrence; and the Atlantic Ocean east of Newfoundland.

Details of the surveys revealed that sea creatures adhere to a “complex mosaic of local climate velocities,” the researchers reported. On average, changes in temperature for North America moved north a mere 4.5 miles per decade, but in parts of Newfoundland that pace was a speedier 38 miles north per decade. In areas off the U.S. West Coast, temperatures shifted south at 30 miles per decade, while in the Gulf of Mexico velocities varied from 19 miles south to 11 miles north per decade.

Animal movements were just as motley. As a whole, species shifted an average of 5 miles north per decade, but 45 percent of animal specific populations swam south. Cod off Newfoundland moved 37 miles north per decade, while lobster in the northeastern United States went the same direction at 43 miles per decade. On the other hand, pink shrimp, a staple of Gulf Coast fisheries, migrated south 41 miles per decade, the researchers found.

New Website Brings to Light State’s Rich Coastal and Ocean Data Inventory

SACRAMENTO, Calif. – Today the Ocean Protection Council (OPC) and the California Department of Technology launched the California Coastal Geoportal. The goal of the Coastal Geoportal is to help users learn about coastal and marine environments by facilitating the discovery and distribution of geospatial data layers. The data is accessible through the California Geoportal, the state’s go-to resource for geospatial information.

“California’s wealth of ocean and coastal information is now easily available,” said California’s Secretary for Natural Resources and Ocean Protection Council Chair John Laird. “This will lead to smarter decision-making at all levels of government as we plan for the future of our coastal communities.”

The new Coastal Geoportal provides state agency staff and the public with a user-friendly website for finding high priority coastal and marine datasets, such as aerial photos, marine protected areas, and coastal habitats, with links to the data sources. Users can view the data on a map using the Coastal Viewer, share maps, and overlay multiple data layers to see what is happening on our shoreline and out in our ocean. The Coastal Geoportal also includes a list of tools and resources where one can discover other related data holdings and tools, including the NOAA Sea Level Rise Viewer and California’s ocean observing data. This increased access to datasets will improve the use of scientific information in coastal and ocean resource management decision making.

“Today’s technology brings us many new ways to share information about the ocean and coastal environments; it allows us to collaborate with the public to achieve the goal of protecting our marine ecosystem for the future of California,” said California Lieutenant Governor and Ocean Protection Council Member Gavin Newsom. “The launch of the Coastal Geoportal is a solid step towards embracing this new technology and meeting that goal.”

The Coastal Geoportal was developed by the OPC and the Department of Technology with significant input from the California Coastal and Marine Geospatial Working Group, other state agency staff, and nongovernmental partners. This was done in response to AB 2125 (Ruskin, 2010), which directed the OPC to increase access to scientific information.

Sam Rauch, NOAA acting administrator for fisheries, testifies about 10 year rebuilding timeline

SEAFOOD.COM NEWS [seafoodnews.com] Sept 12, 2013 – In Congressional testimony on Monday, NOAA Acting Assistant Administrator for Fisheries Sam Rauch responded to the latest NRC report calling for more flexibility in stock rebuilding timelines. A portion of his comments are below:

“We`ve heard concerns from stakeholders that the 10-year rebuilding timeline may be arbitrary and too restrictive.

In response to these concerns and similar concerns expressed by Members of Congress, in 2011 NOAA commissioned the National Academy of Sciences` National Research Council (NRC) to conduct a comprehensive evaluation of success in stock rebuilding and identification of changes made to fisheries management in response to rebuilding requirements. NOAA asked the NRC to study seven topics related to rebuilding to help us and the Councils better construct efficient and effective rebuilding plans.

The NRC rebuilding study was released on September 5, 2013. We are thankful for the in-depth and forward looking review provided by the NRC, and at present we are carefully analyzing the report`s details. The timing of the report fits nicely with our work to revise National Standard 1 Guidelines. Since the guidelines were last updated in 2009, a number of issues regarding the application of the guidelines have been identified by stakeholders and managers, and these issues may warrant revisions. An Advanced Notice of Proposed Rulemaking was published on May 3, 2012 to solicit public input, and several report findings reflect possible revisions to the guidelines similar to those currently being considered by NMFS. At this time, NMFS would like to acknowledge a few aspects of the report:
