DSCN2164a

You can start some good arguments/discussions in a group of anglers by bringing up the subject of color.  Everyone has an opinion on the importance of color in catching fish, and some guys have several opinions.  What I will tell you is that we know that fish can see colors, that is a scientific fact.  It ain’t rocket science, but it is fisheries science.  We even know that different species of fish have different sensitivities to different colors.

Carter Lake Revisited

It has been going on three years since the rotenone renovation of Carter Lake just across the road from the Omaha’s Eppley Airfield.  That was done as part of a major Aquatic Habitat Rehabilitation project.  If you want to review the amount of work done, how extensive the project was at Carter Lake, here are some links that provide more details, http://magazine.outdoornebraska.gov/2010/10/carter-lake-renovation-update/ , http://www.iowadnr.gov/Portals/idnr/uploads/water/lakerestoration/12report.pdf .  Yes, that last link is to a document published by the Iowa Department of Natural …
