I can provide some info. My name is Michael Flinn and I am a professor at Murray State in the Biology Dept. You can reach me by phone at

mflinn(at)murraystate.edu. These are experimental gill nets that are part of an Asian carp study that has been going on at Murray State Univ. for the last year or so. We are netting Asian Carp in several areas of the lake mostly between Ledbetter and Blood River. We are examining their gut contents and determining diet selectivity with the phytoplankton in the lake and the samples collected and Hancock Biological Station on their bi-weekly cruises.
We have been experimenting with the best way to mark these nets. In the winter we didn't have many problems with boaters/fisherman as we were setting the nets relatively deep. Now that the carp have moved up shallow we are having to run them shallow. All of our nets are marked with jugs that say HBS in large letters (Hancock Biological Station) and should have a phone number on at least one jug. We also have a net tag (metal and engraved) on at least one end of the net with name and phone number.
I appreciate the fact that we just can't go setting nets however/wherever we like. The reality is that the last thing we want is to lose a net or have someone cut it up. We have a ton of money invested in the nets. My grad student walked into my office this morning and told me that one of the nets was cut in half and floating on the surface when he got to it Sunday morning. During the summer we tried to avoid weekends in hopes of decreasing possible run-ins with boaters, but now that my students are in class they mostly run nets on the weekends. They typically set them out just before sunset, run them at first light, leave them soak Saturday, run them at sunset, and then run them at first light on Sunday.
We do have research collecting permits and are not bound by the commercial fishing rules. That said, I understand that most anglers/boaters likely expect that if they see a line of jugs they are expecting a net or line that is several feet under the water. Many of our nets are 12 feet tall (deep) and several hundred feet long. When we set the nets in shallow water we typically tie them in the shallow areas so they are compressed in hopes of keeping them out of any props. We have been marking all nets with jugs that have reflective tape on them and have discussed marking the ends with larger buoys that have a tall flag on them (in hopes of increasing visibility).
I expect that with future research on the lake and much of it dealing with asian carp this type of net will become much more common. They are pretty much worthless for anything but carp as they have 5" bar at the smallest opening. We catch a few big catfish as bycatch and few buffalo, grass carp and a few gar that are likely picking at the fish in the net, but that is about it.
I'd be happy to discuss any ideas you have about ways to increase their visibility for boaters etc. I'll discuss ideas with Paul Rister as well.
Again, sorry about the cranks. I spend a lot of time on the lake (fishing for fun and research) and am just trying to figure out what these carp are going to do to the ecology of the lake.
