While spending a nice long Memorial Day weekend at our country home we were there to see a literal toad "orgy" going on in our 1 1/2 acre pond. There were more toads than I have ever seen in one place ever.
These looked like the common toad that we often see on the back yard but they were all in the pond doing what comes naturally.

I've read that toads and toad tadpole can cause a fish kill and with the number of toads mating there this weekend I'm concerned about what may happen when the eggs hatch from this seasons mating.

Does any one have any experience with toads causing a fish kill?
Our pond is stocked with LM bass, blue gill, crappie, and perch and has an aeration system running 24 X7 this time of year.

Thanks!
