A Carp Anglers Group Fishing social will be on June 23rd in Coon Rapids. If you enter the park from the Coon Rapids side (Egret Blvd), take a left from the parking lot and drive towards the picnic shelters. Take a right at the first stop sign and park in the lot. We will be fishing in the stretch or river behind the picnic shelter/playground. Start time can be before 7am and you can fish into the evening if you want. There will be medals for the 3 largest fish captured.

Some Common Misconceptions about Carp
BY EVAN CARTABIANO - B.S. M.S & MATTHEW HOWARD
CARP CAUSE THE TURBIDITY OF THE WATER TO BE HIGH (CARP MAKE THE WATER MUDDY).
The answer to this question is that it depends on what the physical characteristics of the water are. In smaller ponds with a silt substrate, Common Carp can cause a noticeable impact on turbidity if high enough concentrations of fish are reached (Barton and Kelton 2000). However, Fletcher et al. (1985) found “no association between high carp densities and high turbidity” in several larger water bodies and concluded that hydrologic changes were to blame and water level fluctuation reduced the amount of water plants, further exacerbating the issue. This would be applicable to many of the larger reservoirs and rivers in the USA.
Looking at everything as a whole, Common Carp can cause a increase in turbidity in some systems if that system has a substrate that is conducive to be suspended in the water column. The existence of Common Carp is not the only factor of making the water muddy, and wind and sediment type (Lougheed et al. 1998), as well as boat traffic (Anthony and Downing 2003) are all significant factors that often produce huge effects on water clarity regardless if Common Carp are in the water or not. The effects of boat wakes in particular are striking, with up to a 50% increase in turbidity over up to 56% of the lake (Anthony and Downing 2003). In general, hard substrates such as gravel produce significantly less turbidity than clay or silt (Crivelli, 1983).
Another consideration is eutrophication. Eutrophication is an excess in nutrients, especially Nitrogen (N) and Phosphorus (P), in a body of water that ultimately leads to a surge in algal growth. These algal blooms can cause incredibly destructive effects such as increased turbidity and asphyxiation through oxygen crashes. Eutrophication can occur through a variety of sources; human activity is the main source. Run-off water from agricultural land (or lawns) containing fertilizers that are rich in nutrients are a large cause, as well as large urban areas, sewage and industrial discharges (Ansari & Gill, 2013).
CARP RUIN THE NESTS OF SPAWNING BASS AND THIS CAUSES A PROBLEM.
Do carp eat bass eggs? Wolfe et al. (2009) conducted an experiment in which Largemouth Bass were stocked into a controlled environment, both with and without Common Carp. The results showed that juvenile bass stocked into enclosures containing common carp survived at a higher rate than bass that were stocked without Common Carp. The experiment was then repeated with older juvenile bass and the results were the same. The bass had a higher survivability in the presence of Common Carp. The study also found that during the experiment, Common Carp were observed feeding in the clay bottomed enclosures but egg predation on largemouth bass eggs appeared to be minimal or absent, perhaps as a result of male bass guarding the nests. Male bass also fan the nest with their tails to prevent the accumulation of silt over the eggs (Wolfe et al. 2009). These findings indicate that Largemouth Bass can successfully spawn with Common Carp with little or no negative effects. The findings also indicate that carp pose little or no risk to the survivability of largemouth bass young.
CARP EAT ALL OF THE WEED WHICH DAMAGES SPAWNING SITES FOR THE BASS.
The impact of Common Carp on aquatic vegetation is varied with some studies finding an no impact (Drenner et al. 1997, Fletcher et al. 1985) and others finding one (Crivelli, 1983). It is worth noting some aspects of Largemouth Bass biology as well. Bass nests are typically found in shallow water in substrates such as sand, soft mud and gravel (Roberge et al. 2001; Moyle 2002; McPhail 2007). Largemouth Bass often nest next to weeds or other structure, but do not nest on weeds.
CARP OVERTAKE A WATER CAUSING PROBLEMS WITH OTHER SPECIES.
Carp overtaking a water is never a good thing, just like it is never good for Largemouth Bass to take over a water, or Crappie to take over. The result is a stunted population and reduced fish condition, growth rate and maximum size - and poor fishing. How this impacts other species depends on many factors, and which species interaction is examined. While Common Carp do not feed on other fish or fish eggs intentionally, Common Carp can, at high densities, increase the turbidity of the water, at least in shallow silt bottom ponds (Breukelaar 1994; Roberts et al. 1995). This can impair the feeding on sight feeding predators such as Largemouth Bass or Pike and result in decreased growth rate of these species. It is worth noting however that Common Carp eggs are preyed upon by many smaller species (Bajer et al. 2012), which in turn provide food for the predatory species.
There are a huge number of studies on Common Carp, looking at many aspects of biology, ecology, and cultivation. Many studies conducted in both the USA and Australia have been conducted with the ultimate goal of Common Carp eradication in mind. Like with any other fish species, Common Carp can causes issues in some situations and under these situations management is required.
However, under many, perhaps most, situations Common Carp have little or no effect on other species and other factors are the cause of undesirable environmental conditions. The points discussed here are a small part of the topic and are simply a starting point for a larger work that is in progress.

By Rick · PostedThe Minnesota Department of Natural Resources has confirmed zebra mussels in McCarron Lake in Ramsey County. A person trained in invasive species detection found six zebra mussels near the public access. A DNR survey found six additional zebra mussels north and south of the public access. In both cases, the zebra mussels were attached to rocks and muskgrass in 1 to 3 feet of water. Ramsey County staff conducted a targeted search and confirmed a lakewide zebra mussel presence. Whether or not any invasive species has been confirmed in a lake or river, Minnesota law requires boaters and anglers to: Clean watercraft and trailers of aquatic plants and prohibited invasive species. Drain all water by removing drain plugs and keeping them out during transport. Dispose of unwanted bait in the trash. Some invasive species are small and difficult to see at the access. To remove or kill them, take one or more of the following precautions before moving to another waterbody: Spray with high-pressure water. Rinse with very hot water (120 degrees for at least two minutes or 140 degrees for at least 10 seconds). Dry for at least five days. People should contact an area DNR aquatic invasive species specialist if they think they have found an invasive species in a waterbody where it has not already been confirmed.

By Rick · PostedThe Minnesota Department of Natural Resources invites the public to an open house to learn about updating the master plan for the David Dill-Arrowhead State Trail in St. Louis and Koochiching counties. The open house will be from 6-8 p.m. on Sept. 4 at the Cook Community Center, 699 3rd Ave. S.E., Cook. The main parking lot and building entrance are along Gopher Avenue. Visitors to the open house can review information, ask questions and submit comments. The David Dill-Arrowhead State Trail is about 125 miles long, stretching from an intersection with the David Dill-Taconite State Trail, just east of Tower, northwest to an intersection with the Blue Ox Trail, just south of International Falls. The current master plan was written in 1980 and revised in 1983. The trail is primarily managed for snowmobile use, but other uses such as hiking, biking, horseback riding and skiing are permitted in certain areas. Written comments may also be submitted by emailing [email protected], using the online comment form or sending via US mail to Joe Unger, DNR Parks and Trails, 500 Lafayette Road, St. Paul, MN, 55155. The DNR will accept written comments through Sept. 18. More information can be found on the David Dill-Arrowhead State Trail webpage. Discuss below - to view set the hook here.
By Raven77 · PostedDisappointing. Had a mushroom/Swiss burger there last week. Small, dry, overcooked with a small dab of what looked like mushroom shavings. Wife had a salad with grilled chicken that was tough as shoe leather. I was really hoping for better as our cabin is close and we enjoy eating out.
By BobT · PostedWas out on Osakis yesterday evening on some midlake humps using 1/4oz jigs with leeches in the hopes I could find a few cooperative walleyes. I was getting pestered by what I thought were perch stealing my leeches. I'm a slow learner so it took too long for me to finally downsize my presentation until my dozen leeches were nearly gone. I finally downsized to 1/8oz digs and caught fish. It was 10" sunnies that were stealing my bait. Once I figured that out, I grabbed my crappy/sunny rod with a flu-flu jig and proceeded to have a pretty good time catching sunnies. I had a container of crawlers with me and just cut them up to tip the jig. Kept five for a meal but could have easily filled out. They were near the bottom in 18' of water.
By Surface Tension · PostedFishHawk and Depth Raider are your choices as Sub Troll and Canon are no longer manufactured. If you don't have any of the above your relying what you see on your sounder and for speed your looking at the blow back or the timing of the thump from a Flasher. Interpreting speed at the ball this way is a guessing game but it works along with varying your speed. It might not tell you a precise speed but you should be slowing and speeding up not matter what method for speed your using. If you set your speed at 2.5 and stick there all day your probably won't boat as many fish as if you were coming in and out of 2-3 MPH all day. Would speed and temp at the ball be useful, absolutely. Wouldn't it be nice to know that fish hit at 75' down in 45 degree water at 2.8 MPH. Maybe you it was on a speed up or down when it hit too.
By Wishin4Walleyes · PostedWent out of agate in 2 harbors on Saturday from about 8 am to 2 pm after missing the last couple weekends (family vaca). Tough bite. Had 1 short strike on the rigger at 50' with a spoon and 1 screamer hit a tail dancer long lined on a board (must've been a pretty good sized steelie as I've never seen a board disappear behind the boat like that before). Unfortunately it came unpinned. 0 for 2 in 6 hrs of fishing. Tried depths from 20 to 70, tried plugs, spoons, flies, etc. Talked to another gent at the dock and they managed 14. Really love hearing that when you come off defeated and someone out in the same area doing mostly the same things lights them up. Looking at getting a fishhawk x2 to try and find the thermocline and get on the fish faster. Anyone have experience with the down temp/speed devices on the market and are they a must have like I've heard from some?
