I thought this might spark some good conversation, as well as quell my interest. I know in my lifetime the channel cat population in the missouri has changed, and even more so in the last 5 years or so. I hear the older fellas talk about it also, the so called good old days. The blues and flatheads are thriving these days, so why not the channels. Could it be the influx of bigheaded carp eating the fry. If so then why are we not seeing a trend down with the other species of catfish. I know the MDC has been doing extensive flathead studies with the tagged fish, as we have caught 5 tagged fish this summer alone in our area. I would like to hear the population numbers from flathead studies, I believe the flathead numbers are increasing fairly quickly now that commercial fishing for cats is not allowed. Could this possibly be a contributing factor to channel cat populations declining? Another perspective to view is; besides in lakes, are there any rivers that truly hold great numbers of channels, as well as trophy size flathead, and blue populations, all in one environment. I don't mean in certain sections of the mississippi where channels are strong, and not the others, but one section where all 3 seem to strive in great numbers and size. Is there a correlation between the three as far as; can all three reach trophy potential without impacting the success of one of the others. I don't know the reasons; what do you fellas think?
