Water Color and Populations

Could it not also be possible, that Black Crappie fry have a different diet, and are not impacted as much ??
I've also heard that the lakes went thru a couple of years of drought conditions, and that may have impacted the spawns of those years.
The "grass/water weeds" are also supposed to be making a comeback, and that bodes well for the Black Crappie (which prefer weeds/clear water ... think Canadian border area and Florida ;) )
White Crappie do prefer murky/warm waters, and Black Crappie prefer clear/cooler waters ... so maybe the changing conditions of the lakes has more to do with the domination change, than other factors ?
... cp :cool:
You are right CP. There are several reasons for the water clearing up here on Ky. Lake. You mentioned Zebra Mussels. Un fortunately my industry (tow boats) and pleasure craft are primarily responsible for the introduction of the Zebra Mussel into the lakes. They attach themselves to the hulls of boats & barges and get a piggyback ride to other river systems. They are also found in ballast water. They are a problem.
Anytime you introduce a non-native species into an ecosystem you are asking for trouble! It takes decades for that system to evolve and adjust to the new addition to the family.
The weeds are coming back too. They made an attempt to keep them out a few years ago but they are on the way back. I for one welcome them but your pleasure boaters and skiers don't like them much. :D They act like a filter and sift out sediment and cause it to settle around the weed beds. That’s one of the ways they get their nutrients.
You are also right that for the last few years the water flow has been down. The age of the lake has also contributed to the clarity. Most of the soil has long since washed off the banks & exposed rock causing less muddy runoff. Many farmers have changed their practices and gone to no-till as well as CRP/Set aside programs. All of these are contributes to the change.
As for the fish population... Anyone who thinks that the crappie population in these lakes is in great shape is kidding themselves or just don't know what it used to be like.
BadBrad mentioned in his last post about the abundance of crappie in the "old day". He was right. I was there. I can remember my granddad & I fishing in Ky. Lake for years and if we didn't catch 150 or 200 BIG crappie a day he thought the fishing was slow! :eek: Unfortunately many of our parents and grandparents thought that the fishing would last forever. We know better today.
There used to be no limit. Then they imposed a 60 fish limit, then 30, then 30/ 10 inch, now 20 / 10 in. Folks the horse is already out of the barn! You can say what you want to about how great the new limit is but you'll see 10 or 15fish limits in a few years. When they set the limit at 30/ 10 inch fish I told my dad that it wouldn't be but a few years and they'd drop it to 20. It was a no brainer. I spend between 120 & 150 days a year chasing these fish & I see the changes first hand. The new limit alone WILL NOT fix the problem!
With today's fishing pressure, boats, technology, movement studies, lures, poles, books, videos, etc... A poor'ol crappie don't stand a chance.
Sooner or later they're gonna see how much crappie mean to the local economy and get serious about the problem. It chapps my fanny! You let 1 Elk die and KDFW is jumping thru their butt to see what happened and try to head off a problem. The crappie around here have made millions of dollars for this state over the years and all they can do is slow the leak!
Folks I hate to sound so negative but sometimes the truth hurts!
BTW I don't claim to have all the answers. My tax dollars and licence fees are suposed to pay for people to figure it out.
No Pole Restriction For Me

I agree. A pole restriction would not be popular with the spider riggers. :(
