Be happy! Eat more sardines!
Seasonal Affective Disorder (SAD) was discovered by Dr. Norman Rosenthal after noticing that his own sluggish mood -- first noticed after moving from sunny South Africa to New York -- improved after exposing himself to bright light. SAD affects about 8 percent of people in wintry New Hampshire but less than 2 percent in Florida. Lack of sunlight may alter sleep-wake cycles by means of nerve signals from the eye to the brain's biological clock (the suprachiasmatic nucleus) with the help of melatonin from the pea-sized pineal gland.Although Iceland's daylight diminishes, due to their near-arctic latitude, from over 9 hours on October 20 to just over 4 hours in December, its SAD prevalence of less than 4 percent is much lower than that of U.S. or European locations with equivalent levels of seasonal darkness. In fact, Icelanders are among the happiest people in the world -- despite their 2008 financial crisis, volcanic eruptions, and the predominant winter darkness. In addition to their helpful social support and encouragement of out-of-the-box lifestyles -- the mayor of the city of Reykjavik, Jon Gnarr, who is also a comedian, as an example -- Icelanders believe that their high consumption of ocean fish and fish oil helps them cope. Oil-rich cold-water fish like salmon, cod, and sardines, fish oil supplements, and some plant-based foods like walnuts contain omega-3 polyunsaturated fatty acids, which research on other mood disorders suggests have an antidepressant effect. We've known for quite a while that eating fish correlates negatively with major depressive disorder.Read complete story here.
RECIPE: Kalamarakia Yemista-Stuffed Squid
If you read my post about the Top Fish competition, then you know that I recently made a stuffed squid dish that landed me in third place. I am pretty proud of that recipe, and I'd like to share it with you.I have served this dish to many friends, and they all enjoyed it. What is difficult about cooking squid is that you either need to cook it quickly or over a very long period of time, making sure that it doesn't get rubbery. The way I prepare it is to bake it quickly, and it doesn't take ages to chew—win win.
The prep for this dish takes about 10 to 15 minutes depending on your knife skills; I usually like a chunky chop, but with the squids being so little, you are going to want to chop everything pretty small.Full recipe and story here
DFG and Partners use Aircraft and Submersible Camera to Count Pacific Sardine
Department of Fish and Game (DFG) pilots and biologists, along with partners, used new technological tools above and below the water to study the sardine fishery.
DFG, in partnership with the California Wetfish Producers Association, flew over Southern California waters in DFG’s Partenavia P68 Observer aircraft to complete surveys for Pacific sardine in coastal waters. Also for the first time, DFG confirmed the aerial identification of the fish from a vessel positioned on the schools, using a submersible video camera. During the August surveys, DFG biologists photographed schools of sardine to capture distribution and abundance.“These surveys will help DFG to manage this sustainable fishery and add to our limited understanding of sardine distribution throughout the Southern California Bight,” said Michelle Horeczko, Senior Environmental Scientist on the Coastal Pelagic Species Project. “Data from these surveys may also be used by West Coast scientists as part of a new effort to look at the full range of sardine data from Canada to Mexico.”Continue reading full story here.
Is Fish Poop Critical To The Ocean?
Professor Deborah Steinberg of the Virginia Institute of Marine Science (VIMS) has dedicated her professional life to investigating crustaceans and their role in the “biological pump,” which is the process by which marine life transports carbon dioxide from the atmosphere and ocean’s surface to the deep sea. This cycle removes the carbon to a depth where it contributes nothing to global warming.
In a new study published in Tuesday’s issue of Scientific Reports, professor Steinberg partnered with Dr. Grace Saba of RutgersUniversity and retrained her focus from crustaceans to small forage fish in order to gain an understanding of their role in this carbon removal process.The research pair collected their data off the coast of southern California on an exploratory expedition aboard the research vessel Point Sur. Building on Steinberg’s knowledge of copepods and other small, drifting marine animals, gleaned from two decades of research, the team wanted to explore whether forage fish like crustaceans played a discernible role in the biological pump through their consumption of photosynthetic surface algae and subsequent release “fecal pellets”.Read full story here.
Eating Fish While Pregnant Halves the Risk of ADHD
The amount of fish a woman eats while pregnant may affect her child's chances of developing attention-deficit/hyperactivity disorder (ADHD). Eating fish twice a week was linked to about a 60 per cent lower risk of a child developing certain ADHD-like symptoms, according to research from the Boston University School of Public Health.But the type of fish eaten is key.Elevated mercury levels, which can occur from eating certain types of fish, such as tuna and swordfish, were also tied to a higher risk of developing ADHD symptoms such as a short attention span, restlessness or being easily distracted.'The really important message is to eat fish,' said assistant professor Sharon Sagiv, the study's lead author.Read full story here.
Fish on Fridays: Omega 3s vs. Mercury - Is Seafood Good For You?
It seems there’s a never-ending see-saw battle in scientific research about certain consumables. Red wine will decrease incidence of cardiovascular disease! No it won’t. Dark chocolate will lower your body mass index! Or not.Seafood is no different. For every report that Omega 3 fatty acids are the fountain of youth, there’s another study warning seafood lovers about looming poison from excessive quantities of heavy metals, especially mercury. But are Omega 3s really that beneficial? And what to make of reports that selenium in fish can counterbalance the negative effects of mercury? And just what the hell is selenium, anyway? What’s the truth about fish?Of course, there’s no black-and-white answer, but I’ll try to sort through a few of the bigger issues and provide a bit of guidance about what to look for at the fish counter to maximize the benefits and reduce your risk.First of all, a disclaimer: I’m an ocean policy wonk, not a doctor, so take all this info with a grain of salt (figuratively, people, watch that blood pressure!) and ask your doctor if you have deeper questions—particularly if you’re pregnant.Read more here
Fishermen Cash In On Giant Demand For Squid
Seeing more restaurants offer calamari on their menus brings a huge smile to Neil Guglielmo's face.The rising popularity of the marine delicacy has helped Guglielmo and fishermen like him in Ventura County rake in more revenue, especially within the past few years.Owner of the Captain Squid company and captain of the 70-foot squid fishing boat the Trionfo, which unloads its catch in the Port of Hueneme five days a week, Guglielmo said the past few seasons have been some of the most profitable years he has seen in his more than 50 years of fishing."The past couple of years have been phenomenal for squid fishing and so far, we're doing really good," Guglielmo said. "A few years ago, we would come back with our catch and fish market (officials) would tell us they already had enough. Nowadays, they get mad when we don't go out."Fishermen throughout the nation saw some of their highest catch numbers in years in 2011. According to a recent report released by the National Oceanic and Atmospheric Administration, the U.S. seafood catch logged a 17-year high last year.Read full story here- vcstar.com
Fishery Management: An Analysis of Fish Stock Assessments
Center for American Progress
Counting Fish 101
An Analysis of Fish Stock Assessments
George Lapointe, Linda Mercer, and Michael Conathan
Science is integral to fishing operations. Without the ability to estimate how many fish exist in the ocean there’s no way to determine how many of them we can catch while allowing the remaining fish populations to stay viable. But fish live in a mostly invisible world beneath the ocean surface, they move around constantly, and they eat each other.
This creates a dynamic population structure that’s incredibly difficult to track, making fish virtually impossible to count. Thus, fisheries scientists—like political pollsters or other statisticians—must rely on imperfect data to make their predictions about the status and health of fish populations.
They take these data—some of which they collect, some of which come from fishermen—and plug them into scientific models which, in turn, create estimates of population health. Because the entire population of a given species is frequently divided into subpopulations known as “stocks,” these estimates are called “stock assessments,” and they form the backbone of modern fishery management in the United States.
These assessments provide an estimate of the current state of a fish population and, in some cases, forecast future trends. This tells us whether fishery management goals arebeing met and indicates the type of conditions to which the fishery will have to adapt in the near future. In an ideal world, scientists would have the resources to provide managers with updated stock assessments for each species every year, but their expense and complexity mean they can only be updated periodically.
Regardless of how frequently they can be updated, strong, science-based stock assessments are the key to future sustainability, not just of the fish but also of the fishing industry. Fishing is an inherently unstable business, yet strong, accurate science can give fishermen a better understanding of whether their resource will remain healthy, and if it does, how many fish they will be allowed to catch. This in turn allows fishermen to make informed business decisions and stabilizes coastal economies.
