Traces of Mercury

12 posts in this topic

I've been hitting some nice 12-14 inch Crappies on a lake.

Caught a couple Walleyes too. As I read some lake info. on the DNR site, it says Mercury has been detected in Walleye and Northerns.

Would you eat fish from this lake?

There usually is a fish consumption advisory on each lake the dnr monitors. Check that out it will tell you how many meals per week are safe and so on. . .

That would depend. What lake are you fishing? wink

Just make sure you watch how many times you eat them per month and so on.

Here is a story on Fox 9's web site today.

MPCA: Mercury Levels in

Fish Rising

Created On: Tuesday, 17 Feb 2009, 5:56 PM CST

ST. PAUL, Minn. - The Minnesota Pollution Control Agency says the amount of toxic mercury in northern pike and walleye has been increasing unexpectedly since the mid-1990s.

The MPCA reported the increase on Tuesday. MPCA scientists analyzed tissue obtained from fish collected from 845 Minnesota lakes over 25 years. The MPCA says the finding is a concern because the mercury in the fish is toxic to humans and wildlife.

Because the trend is statewide, the MPCA says a local source of mercury is likely not responsible.

MPCA scientist Bruce Monson says the cause is most likely increased coal burning in other countries, or factors associated with climate change -- or both.

Minnesota is working with scientists from the other Great Lakes states and provinces. Monson says the hope is to combine data and create a database that will allow officials to look at regional trends.

"While mercury levels in fish declined 37 percent from 1982 to 1992, they spiked back up 15 percent from 1996 to 2006"

-Bruce Monson, PCA scientist.

Although not good.

22% less mercury than pre 1992 levels.

What happened from 92-96? 22% less mercury than pre 92 levels seems suspicious, especially when there is 4 yrs of missing data?!?

      leech, it does sound like an odd concocktion.  but you gotta try it.  225 for 2 hrs, helps if u use thin bacon.

      Man, I can see cream cheese but peanut butter? I may have to give it a go sometime, maybe the bacon will off set the oddness? :eek:  :)

    • Sorry I missed that. The brown and blue wires are the Transmit TX and Receive Rx wires for connection via single cable to NMEA 0183 compatible devices. nmea 0183 is the protocol for compatible devices, computer, plotters, auto piolet, Radar, radio, etc. All of these devices including your GPS can be connected to a single cable. The brown and blue wires allows the sonar to communicate to other devices. Google nmea 0183 compatible devices for a raft of information on what this is.

      My brother, a charter Capitan out of Cortez FL. uses these devices on his boat for off shore fishing up to 100 miles off shore. Nice to have to talk to other Capitan's ship to shore, radar, GPS and  to get back home without running into sunken islands.

       

    • Trump stumped on terrorist quiz as he can't identify the leaders of ISIS and al-Qaeda – but Carly Fiorina shows she knows her Nasrallah from her al-Julani

      • Radio host Hugh Hewitt asked Trump and Fiorina the same questions about terrorist leaders in separate taped interviews on Thursday
      • FIorina answered confidently and Trump seemed flummoxed, confusing 'Quds Forces' with 'Kurds forces'

      I ask the same thing about the other 2 candidates, especially the one that is your favorite.

      That would have been a fine answer.   Unfortunately instead he sat there with his mouth hanging open (figuratively) and looked like a total dolt.   This is the second time he has handled something in an interview poorly.  I guess he feels he needs the exposure but unfortunately he is not especially good at the interview thing.   At the very least he needs to practice deflecting the question.  Perhaps the "nobody especially" but "I prefer to look to American leaders of the past like (Calvin Coolidge, Teddy Roosevelt, Thomas Jefferson, William Calhoun, whoever he wants)" 

      He can't just sit there and and look stupid, which is what he did.    Maybe some role playing in preparation would have helped.   He can't be as ignorant and inept as he has come across in TV interviews.  

      What do you care? I thought he was irrelevant anyway?

       

    • Oh yeah.  I keep forgetting about all that modern computer stuff in cars.   So the computer would notice the tranny didn't shift all the way down as the car stopped?     There goes that theory.   

      And why only after a couple hours of driving?   Some sort of overheating of the transmission fluid?  cooler plugged in the flush process?   

      Here is a question for Carpmaster..... Is it different in the summer vrs winter?   Like you only have to drive 50 miles in summer and 200 in winter?  

      You guys that actually know can feel free to ignore my suggestions if you don't want to waste time answering.
