  1. We talk about blaming the commercial industry for bringing certain AIS such as Zebra Mussels into the state to start with, and it all does start with them for many AIS (i'm talking ballast water in these large barges in the Great Lakes), but once that occurs than it is a multitude of other vectors that further spreads the AIS more regionally, and for zebra mussels it's all boats, not just fisherman, and its water equipment (especially docks and lifts that stay in the water for long periods of time in these infested waters). If you've been on Minnetonka lately and pulled up any milfoil, you can see that it is covered in zebra mussels both large and small, and that appears to be the biggest risk of infestation for a new water body, aquatic plants with zebra mussels attached hitchhiking on a boat or trailer. There have been two instances already this month in Minneapolis, inspectors at Lake Harriet stopped two sailboats that came from Minnetonka, one had zebra mussel shells in the sailboat, while the other had vegetation attached to the trailer which had zebra mussels on them. To me, the steps of cleaning off our boats and trailers of vegetation, removing the drain plug and draining the water to the best of our ability is really pretty simple and doesn't cause me too much heartache. The bait law to me still stinks, as many people don't stick their bait bucket in the water, how does one verify if the water came from the lake or tap, and so on..... Also, the larger amount of water, the higher the risk of zebra mussel veligers being present, which is why the ballast tanks of wake board boats is a concern, but seriously, one gallon of water in a bait bucket, I would say the odds of a zebra mussel veliger being present is pretty low, but the odds of a veliger actually surviving a re-introduction into a new water body is next to 0. Veligers have a mortality rate of 95% under normal conditions in a water body, they are fragile, and introducing very few in a new water body with lots of dilution, the chance of those veligers gaining foothold is low enough for me not to have the law in place. I think ultimately, no matter how many laws you have, there are always going to be a small subset of people that are ignorant and don't care about the law. I think most people try to do the right thing and do what they can.
  2. I feel like every new idea on AIS prevention focuses on stickers, our boats are going to be completely covered in stickers!
  3. Zebra Mussel Veligers, which are microscopic and one of the reasons behind the law on transporting water, have not been found to be present in the cold, winter months. Veligers typically first start appearing in late May early June, and usually disappear by October. Zebra Mussels have certain water temps that are most desirable for reproduction, which in Minnesota typically has been late spring to early fall. The DNR is performing some research this winter to help support these observations, water samples from various lakes in MN will be tested this winter for veligers. However, adult zebra mussels are still alive in the winter and could be attached to aquatic plants, so you still should not transport aquatic plants. It it against the law to transport aquatic plants year-round. Here is the law in Minnesota Statutes 84D.10. Subd. 4. Persons transporting water-related equipment. (a) When leaving waters of the state a person must drain water-related equipment holding water and live wells and bilges by removing the drain plug before transporting the water-related equipment off the water access site or riparian property. ( Drain plugs, bailers, valves, or other devices used to control the draining of water from ballast tanks, bilges, and live wells must be removed or opened while transporting water-related equipment. © Emergency response vehicles and equipment may be transported on a public road with the drain plug or other similar device replaced only after all water has been drained from the equipment upon leaving the water body. (d) Portable bait containers used by licensed aquatic farms, portable bait containers when fishing through the ice except on waters designated infested for viral hemorrhagic septicemia, and marine sanitary systems are exempt from this subdivision.
  4. The Minnehaha Creek, I know for sure if you go through Big Willow Park in Minnetonka and follow the path down to the creek, there are tons of crayfish in there hiding by the rocks, as of last week there was still some standing water in there.
  5. This is an absolute horrbile year for Eurasian Watermilfoil, it is bad everywhere. The mild winter with little snowfall started the growth really early, its usually never this bad in June.
  6. Mallardnwalleye: Just remember that those rates you mentioned for control of native plants such as Coontail, Narrowleaf Pondweed and Sago Pondweed are for large area/whole lake treatments. Not every treatment area would qualify as that, and individual home treatments would not qualify. The rates to control plants in small areas are much higher. To correct one thing, the rate in which Aquathol K controls Coontail in large areas is 2 to 3 ppm. It's really all about contact time, the longer the contact time, the lesser dose it takes to have some impact on plants. For Curlyleaf Pondweed, there is typically no need to worry about native plant impacts because treatments are generally done before natives are up and growing like you mentioned, however this year may be different and I could see how some natives could be affected, but they generally always rebound later in the year or the next year. Curlyleaf can never be eradicated, but it can be controlled to smaller, more manageable areas.
  7. The goal with early season Curlyleaf treatments is to treat the Curlyleaf before the natives are present. These treatments are low-dose, early season treatments. Typically 0.5 ppm to 1 ppm Aquathol K is used, and at that rate the chemical has no effect on other native plants. For the majority of other pondweeds, you need to use at least 2 ppm. Now, if you were to get a rediculous amount of contact time, which typically does not happen, than it may affect some natives. But once again, on a normal year, most natives are not actively growing when treatments occur. This year is much different, there are other natives up but the treatments should not affect them very much.
  8. Thats great if the small lakes you live near have good water quality and no major issues with invasives, there are many lakes that do not have an association and are just fine. But, overall, I would suggest if a lake has an association, there is a reason for it, whethere it is a popular fishing/recreation lake, has invasive species problems, or the lakeshore homeowners just decide to be proactive in caring for the lake. Every lake is different and has different needs. Nitrites and nitrates are not the nutrients of worry in a lake system, for algae growth and aquatic plants it always comes down to Phosphorus and Nitrogen, with Phosphorus often being found in excess leading to increased algae and plant growth. A lake ecosystem is much different than an aquarium. A lot of pollution and excess nutrients are caused from humans, so unfortunately it takes humans to correct these mistakes.
  9. Get educated before you make assumptions, Curlyleaf Pondweed is a contributor to poor water quality. Since it has a uniqe life cycle (dyes off mid summer), when it dies it realeases excess Phosphorus into the water column, often giving way to nuisance algae blooms. It has been proved, that when coupled with other best management practices, and when combined with cleaning up other areas of the watershed, that water quality can be improved greatly. So control of curlyleaf pondweed does benefit the lake water quality. Eurasian Watermilfoil control can be beneficial in certain situations. Lakes with good water clarity and other native aquatic plants can benefit from treatments. The goal in these situations is to reduce the Eurasian, with the hopes that the natives will overtake the area. While you may never be able to completely eradicate the milfoil, it can be reduced to smaller, less nuisance areas. Eurasian Watermilfoil control in other lakes with poor water quality the goal becomes to reduce the size of nuisance (matting) milfoil in areas that are used for recreation. In my opinion, most Lake Associations (not all) have very good intentions on improving water quality and use-ability for their specific lake. They undertake and fund many water quality projects, fish stocking, lake clean ups and other projects that benefit everyone that uses the lake. I am not part of a lake association, I do not live on a lake, but I am a fisherman and I am an Aquatic Biologist.
  10. I don't think it really effects fishing directly, are you saying you never have a bad day fishing when there are no orange signs visible. I think because you can see the orange signs, people get into the mind set that it is going to effect fishing, so it becomes a mental thing. The herbicides are EPA approved and do not affect fish directly. Things that can effect fish from these treatments are the possibility of a loss of habitat, or decrease in oxygen from mass die offs of weeds. Just my thoughts.
  11. Come on guys, you are being rediculous and giving fisherman a bad name. Get educated. The DNR will never win, either they do too little and people complain, or they try to get something done and people complain. I'm glad they are at least trying to be somewhat proactive, hopefully its not too little too late. If we have a chance to reduce the spread of AIS, why not do it. Prevention techniques cost WAY LESS than management techniques, and what they spend on these prevention techniques are far better than the consequences we would deal with the alternative. Think of all the impacts AIS can cause, noted that some AIS are worse than others. A lot of these impacts wont be seen right away, but by the time our kids are adults, they could have to deal with the real consequences. AIS can impact tourism thus affecting the local economy, it can impact fishing in many ways that may not be seen right away, in can impact recreation users, for example zebra mussels can plug cooling intakes on motors causing overheating. Zebra mussels can also litter beaches and the lake bottom with sharp shells, it takes a few years for zebra mussel populations to really explode. Minnetonka is getting worse and worse. If we ever get Hydrilla, that is far worse than milfoil and can give us less useable area in a lake. Google Hydrilla, look at the pics of what it can do. By far the worse AIS in my opinion. You are never going to be able to say you can completely stop the spread of AIS 100%, but if you can at least reduce the chances significantly i'm all for it.
