Wondering how long it takes for the eggs to hatch after being fertilized?
Romans 6:23
Well,,,, I have been told 3 to 7 days. I guess dat is close enough. Craig,,,, de bad news. How quick do de white perch hit de nest. If cover is not there, which predator fish does the most harm after the hatch? <*)}}}><

Chatt,
Since white perch feed upon eggs of other fishes, they basically prey upon the eggs as soon as the eggs are deposited by the female. Egg predation is one way that white perch have a direct negative impact on sportfish populations. I've seen white perch that had their stomachs FULL of walleye eggs at Cheney Reservoir during the walleye spawn.
What predator eats the most crappie after the hatch would probably be determined by the available predator densities in the particular lake. All predatory fish will feed upon smaller fish, no matter the species. Walleye eat young crappie and adult crappie eat young walleye. If smaller fish are in front of larger fish and the larger fish can catch them and eat them, then they probably will! Saugeye have proved successful in reducing overpopulated crappie densities through predation in some of our Kansas State Fishing Lakes and improving the quality of the crappie population. This however requires special management of the saugeye to reach and maintain densities at which increased predation will result. Again, the saugeye doesn't target only crappie but they will eat what is available and what is most easily caught.
In lakes where saugeye don't exist, largemouth bass may be the species responsible for providing the most predation upon crappie. Or it could be numerous other fishes. It just depends on what species share the lake with the crappie.
As long as we're askin....how long do the bucks stick around the nest to guard after the females have deposited? And, am I correct that the females will go to mid water depths (5-9fow) to rest up and feed before heading to summer river patterns?
Males will stay on the nest until the fry disperse (6 to 8 days after fertilization).
Post spawn movements can be influenced by many factors and may vary from year to year within the same water body. Currently in Kansas some of our reservoirs are still very low and water temperatures are roughly a month behind normal. Post spawn movements this year will likely be quite different than a 'normal' year.
