I was out wading around in Lake Riley this morning fishing for bass and I swear I saw at least 20 dead crappies up on shore. I'm just curious if anyone has any insight as to what that might be about? They don't die after they spawn do they? I know at the public beach they just put in that treatment for weeds or whatever but that shouldn't harm the fish should it? And if it does what the heck are they doing? Oh and they weren't concentrated in one area, they were all along a 1 to 2 mile stretch.

for sure they dont die after spawning.. thats pretty much a salmon thing... as for chemicals causing death.. maybe.. it depends on what they were using and in what concentrations... the crappies are probably shallow and spawing.. dumping chemicals on their nests when they are confined to their nests is a nasty business.. and will probably kill the eggs/fry if nothing else...

Are they still spawning? I was wondering that also. When I was out I'd see one here or there right next to shore and it would just sit there. I could get within a foot and they wouldn't budge. I never tried getting any closer because I didn't want to disturbe them but I thought it was strange for sure.

Both sunnies and crappies are spawning right now, as well as guarding their nests. At least the spawn is going on in the twin cities area on the lakes that I've been fishing. THey're bunched up close enough that I took my wife out last night and we were able to sight fish and choose which fish we wanted to catch, and brought home a few for a nice meal of crappies and sunnies. It was a fun time.

Muskies and PIke first, pannies and eyes second, bass and cats a distant third.

Were they smaller fish? Could be anglers using live bait and hooking the fish to deep and not keeping them.

They may not be salmon but every species will have a percentage die off during or after the spawn. Some lakes the die off will be less/more. Water temp/feed/nutrition/oxygen levels will all play a part. You can go on any lake during/after the crappie spawn and find dead fish. Same can be said for gills, eyes, etc, etc.
The spawn is stressful on the fish, a percentage will die off. Lots of depending factors as to what the percentage is but there will be loss.
More than likely those fish died from their spawning efforts.

I read this in some news paper last week (can't rememer which one though). I found this posted on the Wi. DNR website. Not sure if this is related to the dead crappies you saw.

Fish kills
The heavy rains and flooding have added additional organic material to waterways, making conditions ripe for fish kills caused by a bacterial disease called Columnaris.
Columnaris fish kills generally occur throughout the state during May and June each year and should not be confused with the viral hemorrhagic septicemia (VHS) virus which is a new disease feared to be spreading inland from the Great Lakes. Both diseases only infect fish species and are not a health risk to humans. However, people should not eat fish killed by Columnaris or VHS, and should wash their hands if they handle infected fish, because other bacteria that may be harmful to humans start feeding on the dead carcasses.
“The Columnaris bacteria is most prevalent in our lakes after water temperatures reach 65-70 degrees from late May to late June,” says Larry Damman, DNR fishery biologist. The bacteria levels increase after major rainfalls that supply additional nutrients on which the bacteria thrives into area lakes. VHS fish kills tend to occur at temperatures less than 60 degrees.”
Bluegill, crappies, yellow perch and bullheads, already stressed from seasonal spawning activities are most affected by Columnaris. The bacteria erode the fishes’ skin, causing leakage of bodily fluids and a fairly rapid death.
Although Columnaris can appear to produce large scale fish losses in a matter of several days, it usually does not have a catastrophic impact on overall fish populations, according to fishery biologists.
Columnaris was recently found in bluegills, crappies, and other panfish in Dane and Kewaunee counties. As waters warm more fish kills may be expected.
If anglers or landowners have additional questions or see large numbers of dead fish especially non-panfish species like carp, largemouth bass, muskie and walleye, they should contact their local DNR fisheries biologist to investigate the problem.
