On a related note, do you ever fish with a walleye spinner rig or a death roll hook with a pinched crawler? They're probably the most popular way to troll where I live, and folks have been debating for years why the heck walleyes eat them. Now I think I know. The shad die off every year in the winter in monumentally large numbers. Although only a small percentage survives the winter, they reproduce at unbelievable rates, grow like crazy all spring (while being eaten by everything in the water as well as the birds above), then die off in the next winter. The cycle keeps repeating itself. Apparently the bottom of the reservoirs are just loaded with dead shad, which decompose very slowly in the depths. Every big push of water shoves their dead bodies farther downstream, so fish are used to hanging out by the main current and eating rolling, dead shad that drift along the bottom ... looking a lot like a walleye spinner rig or a death roll hook with a pinched crawler.
This stuff interests me as much or more than Nebraska football, if that's believable. I invest a lot of time, money, and energy in trying to outsmart animals with brains the size of peanuts.
