      Members Only Fluid Forum View   08/08/2017

      Fluid forum view allows members only to get right to the meat of this community; the topics. You can toggle between your preferred forum view just below to the left on the main forum entrance. You will see three icons. Try them out and see what you prefer.   Fluid view allows you, if you are a signed up member, to see the newest topic posts in either all forums (select none or all) or in just your favorite forums (select the ones you want to see when you come to Fishing Minnesota). It keeps and in real time with respect to Topic posts and lets YOU SELECT YOUR FAVORITE FORUMS. It can make things fun and easy. This is especially true for less experienced visitors raised on social media. If you, as a members want more specific topics, you can even select a single forum to view. Let us take a look at fluid view in action. We will then break it down and explain how it works in more detail.   The video shows the topic list and the forum filter box. As you can see, it is easy to change the topic list by changing the selected forums. This view replaces the traditional list of categories and forums.   Of course, members only can change the view to better suit your way of browsing.   You will notice a “grid” option. We have moved the grid forum theme setting into the main forum settings. This makes it an option for members only to choose. This screenshot also shows the removal of the forum breadcrumb in fluid view mode. Fluid view remembers your last forum selection so you don’t lose your place when you go back to the listing. The benefit of this feature is easy to see. It removes a potential barrier of entry for members only. It puts the spotlight on topics themselves, and not the hierarchical forum structure. You as a member will enjoy viewing many forums at once and switching between them without leaving the page. We hope that fluid view, the new functionality is an asset that you enjoy .

Asian Carp Invasion knockin on the door

Recommended Posts

kevheads

All thats stopping the invasion into the Great Lakes is a electric barrier in the river in Chicago that connects the Illinois river to Lake Michigan.They prefer colder water and spawn up tributary rivers.I would hate to see in 10-20 yrs,this scene along the northshore.

the feds just won't invest the money to put up these barriers. the MN DNR has been pushing for these barriers for years, and their requests just seem to fall upon deaf ears. I don't get it confused.gif

I am aware that some of the electric barriers, though, were having problems with some of the ships enetering the locks, and there were issues of electric shocks.

To me the feds main concern is the shipping. Rec. and commercial is secondary. Ihate to see what the lakes will be like in 20 yrs.

we should do all we can to stop the spread of non-native fish, plants , and all others. ruffy in island lake?

As long as these big boats make money and whine that its too expensive to treat their bilge waters nothing will happen.

Those Asian Carp look like a major pain in the rear! I wonder how long til they get into our harbors? It will happen unfortanetly.

I just dont think the people who dont live around these parts see it as important. If our waters arent important what is?

I'm not sure if Superior is fertile enough to support these carp? Forage may be an issue.

I agree that the Feds (mainly the Army Corps of Engineers) are more concerned with commerce and keeping shipping lanes. Why else would they destroy thousands of miles of fish habitat for dredging shipping lanes, and turning shore banks into conrete retaining walls? There has been some improvement in their practices in recent years, but it is way too little, too late.

At this point I'd be more concerned with these carp getting past pool 4 on the Mississippi and working there way north, even though I don't want bighead or grass carp in Superior either.

I don't really know much about these electric barriers, but wouldn't that prevent the passage of all fish? It's bad enough that there are dams on the river blocking fish passage (walleye, sturgeon, catfish, etc) but wouldn't these barriers also have a negative impact on our native fish?

But yeah, it makes me sick to my stomach to see our waters get infested with a new exotic. I could never imagine what the river would be like without carp, that'd be insane! About the ruffe, I'm actually surprised that they haven't spread out more than they already are. The st. louis is THICK with them!!! Surprisingly it hasn't seemed to affect the walleye/perch fishing...yet.

It's almost to the point you just want to throw your arms up and say,"Just dump every Goddamn species in the world in the Great Lakes and get it over with now." mad.gifmad.gifmad.gif

yeah they do block all fish. In NW MN there has been a huge effort underway to restore Lake Sturgeon to their historical range throughout the Red River drainage, an effort that has involved many dam removals/modifications. With the latest round of invasives, like the asian carp, some fisheries managers have been considering leaving the last few barriers needed for sturgeon recovery, intact, to keep these carp from migrating past them and spreading further.

      Tamarack Island Wilderness Lodge is pretty accommodating. Grassy Narrows Lodge is one of the nicer lodges in my opinion on the Canadian Southern portion. We made a point of stopping at a bunch of locations last year and this is good sized and really nice. At this point it would be my preferred Lodge on that portion of the lake. Both of these are boat into and on an island. Ryan

      any luck there? i've never had luck. hoping to break my unlucky streak soon.

      Good afternoon guys, I live in Burnsville and I was wondering if anyone has had much luck on Crystal Lake for bass and Pike? I've fished it a few times and only caught 2 bass in a total of 8 hours.  Not looking for any specific locations, but any tips would be much appreciated!!!   Live bait? Plastics? Troll cranks for pike? thanks guys, have a great day. Gabe

      There were 5 maybe 6 boats over at the resort Thursday - Sunday. Heard they were doing some hunting too. Pretty quiet on the bay, most of the docks & lifts are out. Probably going to get real quiet after you show up.

      1) Lumen (lm) Lumen is the international(SI) unit of luminous flux, a measure of overall light emitted by a light source. 2) Candela (cd) Candela is the international(SI) unit of luminous intensity, a measure of light emitted by a light source in a particular direction.
      Any given light source will have different luminous intensities in different directions considered.
      [candela = lumen/solid angle] 3) Beam Angle [Unit : degree] Beam angle is the angle between two directions for which the luminous intensity is 50% of the maximum intensity as measured in a plan through the nominal beam center-line. The beam angle of a lamp gives an idea of how the light beam spread away form the beam center. 4) LUX (lx) Lux is the international(SI) unit of illuminance, a measure of light arriving at a surface, 1 lumen per square foot equals 1 foot-candle, while 1 lumen per square meter equals 1 lux.
      [lux = lumen/m2] 5) Color Temperature / Correlated Color Temperature (CCT) A black-Body radiator will have different color when it is heated up to different temperature(in kelvin). The temperature at which the heated black-body radiator matches the color of the light source is the color temperature of the light source. 6) Color Rendering Index (CR) Color rendering index, ranged from 0-100, measures a light source's ability to reproduce the color of various objects being lit by reference light source, black body radiator (CRI=100) 7) Efficacy (lm/W) Efficacy is the efficacy of a light source to convert electricity power to light expressed in lumen output per unit power input (watt)
      [Efficacy = lumen / wattage] 8) Dimming Not all lighting products are designed for dimming function. None-dimming LED lighting product will cause unpredictable result and may affect the life time of the products. The below figure shows the typical input current variation while adjusting the DC voltage input to dimming and none-dimming product.
