Bluegills fight terrorism

SAN FRANCISCO, California (AP) -- A type of fish so common that practically every American kid who ever dropped a fishing line and a bobber into a pond has probably caught one is being enlisted in the fight against terrorism.

San Francisco, New York, Washington and other big cities are using bluegills -- also known as sunfish or bream -- as a sort of canary in a coal mine to safeguard their drinking water.

Small numbers of the fish are kept in tanks constantly replenished with water from the municipal supply, and sensors in each tank work around the clock to register changes in the breathing, heartbeat and swimming patterns of the bluegills that occur in the presence of toxins.

"Nature's given us pretty much the most powerful and reliable early warning center out there," said Bill Lawler, co-founder of Intelligent Automation Corporation, a Southern California company that makes and sells the bluegill monitoring system. "There's no known manmade sensor that can do the same job as the bluegill."

Since September 11, the government has taken very seriously the threat of attacks on the U.S. water supply. Federal law requires nearly all community water systems to assess their vulnerability to terrorism.

Big cities employ a range of safeguards against chemical and biological agents, constantly monitoring, testing and treating the water. But electronic protection systems can trace only the toxins they are programmed to detect, Lawler said.

Bluegills -- a hardy species about the size of a human hand -- are considered more versatile. They are highly attuned to chemical disturbances in their environment, and when exposed to toxins, they experience the fish version of coughing, flexing their gills to expel unwanted particles.

The computerized system in use in San Francisco and elsewhere is designed to detect even slight changes in the bluegills' vital signs and send an e-mail alert when something is wrong.

San Francisco's bluegills went to work about a month ago, guarding the drinking water of more than 1 million people from substances such as cyanide, diesel fuel, mercury and pesticides. Eight bluegills swim in a tank deep in the basement of a water treatment plant south of the city.

"It gave us the best of both worlds, which is basically all the benefits that come from nature and the best of high-tech," said Susan Leal, general manager of the San Francisco Public Utilities Commission.

New York City has been testing its system since 2002 and is seeking to expand it. The New York City Department of Environmental Protection reported at least one instance in which the system caught a toxin before it made it into the water supply: The fish noticed a diesel spill two hours earlier than any of the agency's other detection devices.

They do have limitations. While the bluegills have successfully detected at least 30 toxic chemicals, they cannot reliably detect germs. And they are no use against other sorts of attacks -- say, the bombing of a water main, or an attack by computer hackers on the systems that control the flow of water.

Still, Lawler said more than a dozen other cities have ordered the anti-terror apparatus, called the Intelligent Aquatic BioMonitoring System, which was originally developed for the Army and starts at around $45,000.

San Francisco plans to install two more bluegill tanks.

"It provides us an added level of detection of the unknown," said Tony Winnicker, a spokesman for the city's Public Utilities Commission. "There's no computer that's as sophisticated as a living being."

They are not in the main basin, they are in a tank fed by same water, besides water gets treated before getting to town, think at Lake Mead....

      Spring turkey hunters hoping to bag a tom during the first two weeks of the season have until Friday, Jan. 26, to apply for a lottery permit. The season runs from April 18 to May 31 and is divided into six hunt periods, A through F (see table below). Hunt A and B licenses for firearms hunters age 18 and older are limited in availability and assigned via lottery drawing. Turkey lottery applications cost $5 and can be purchased online at mndnr.gov/licenses, by phone at 888-665-4236, or in person from a license agent. Successful applicants will receive a postcard in the mail by mid-February and can purchase their hunting license starting March 1. Firearms licenses for hunts C, D, E and F are not lottery-limited and will be available for purchase over-the-counter beginning March 1. All licensed turkey hunters can participate in Hunt F if they have an unused tag from one of the earlier hunt periods. Archery and youth hunters (under 18) are exempt from the lottery and may purchase a spring turkey license valid during all hunt periods, including hunts A and B. Surplus lottery licenses from hunts A and B, if available, will be sold over-the-counter starting in mid-March. Visit mndnr.gov/hunting/turkey for more information about turkey hunting in Minnesota. 2018 Spring Turkey Hunt Periods
      Hunt A: April 18 – 24
      Hunt B: April 25 – May 1
      Hunt C: May 2 – 8
      Hunt D: May 9 – 15
      Hunt E: May 16-22
      Hunt F: May 23-31 Discuss below - to view set the hook here.

      Youth and adults can learn to hunt turkeys this April with experienced volunteers who will cover safe hunting techniques, how to call-in turkeys, hunting tactics and field dressing a bird. “We teach the skills and techniques that allow new turkey hunters to become lifelong hunters,” said Mike Kurre, learn-to-hunt program coordinator with the Minnesota Department of Natural Resources. “This has been a successful program and as a bonus, we love hearing how former participants go full circle to teach others how to hunt.” Participants can apply through Monday, Feb. 12. The hunts are Saturday, April 21, and Sunday, April 22, and provide opportunities to access locations that may otherwise be closed to hunting. “We get volunteers from the National Wild Turkey Federation and this is the 16th year we’ve cooperated for these hunts,” Kurre said. “Over the years we’ve introduced more than 5,000 people to these hunting experiences. We also work with the Minnesota National Guard to get military adults and their families into turkey hunting.” Details about how to apply and costs to participate are available at mndnr.gov/turkeyhunt. A pre-hunt orientation is required and all participants will need to have a valid firearms safety certificate or its equivalent. Youth must be accompanied by a parent or guardian. Overall participation in the hunts is restricted by the number of volunteers and private lands that are available. Anyone interested in providing turkey hunting land for the mentored youth hunts should contact the Keith Carlson, Save the Habitat Save the Hunt coordinator for the National Wild Turkey Federation in Minnesota at kcanoka@comcast.net.   Discuss below - to view set the hook here.

      Gov. Mark Dayton has proclaimed Jan. 20-28 as Snowmobile Safety Awareness Week in Minnesota. This an opportunity for the Department of Natural Resources, volunteer safety instructors, the Minnesota United Snowmobilers Association (MNUSA) and its 250 member snowmobile clubs to join together to recognize the importance of safe, responsible snowmobiling. “It’s a fun and exciting activity, but snowmobilers should always remember to make safety a top priority,” said Conservation Officer Bruce Lawrence, DNR recreational vehicle coordinator. “They should also always use common sense and keep a clear head when riding.” Here are some other key safety points: Snowmobiling and alcohol don’t mix – don’t drink and ride. Smart riders are safe riders – take a snowmobile safety training course. Always wear a helmet and adequate clothing. When night riding slow down – expect the unexpected. Know before the ride  – always check local trail and ice conditions. Cross with care. Know risks and be prepared – make every trip a round trip. One is the loneliest number – never ride alone. Ride safe, stay on the trail – respect private property. To legally ride a snowmobile in Minnesota, residents born after Dec. 31, 1976 need a valid snowmobile safety certificate. Options for both classroom and online classes can be found at http://www.dnr.state.mn.us/safety/vehicle/snowmobile/index.html People can find Minnesota snowmobiling events and activities on the MNUSA webpage: https://mnsnowmobiler.org/get-involved/mnusa/events.

      Hi Wanderer, I am going up this weekend too.  Glad the weather will be warm! I will try a different pit this time, but had good luck last year.  I hope the fish will be active and hungry.
    • IceHawk
      Thanks Rick! Jeff hope to make it always a good time and laughs when you get a group of great people together. I usally do more jaw jacking  then fishing at these things but for me its just as much fun 
    • Rick
      I will donate a few goodies. I will send it to @Tom Sawyer if he messages me his address.
    • IceHawk
      Lol! Smurfy  Its not as easy to identify areas like the old days the ice towns in Mertens bay and in front of Steils old house on cedar island aren't there like years of past but she's still the same chain that you grew up on. And IMO better than when we wee younger.
