In other words, you can determine when spawning will begin and end, and therefore postulate when it might peak, by calculating the number of hours between sunrise and sunset on a given day.Anglers also should remember that crappie almost invariably nest in shallow coves protected from wind and wave action. Finding areas with these characteristics is the key to finding crappie beds. Nests often are near a log or other large object over a bottom of sand, fine gravel or interwoven plant roots. The depth where nests are found can vary considerably, from less than 1 foot to as much as 20 feet. But most will be in 1 to 5 feet of water.Several nuances of the spawn may not be readily apparent. One is the fact that the biggest crappie often are in deeper water when smaller males are first preparing nest sites. For this reason, it's smart to try fishing deeper areas away from shallow-water beds, sometimes as deep a 7 to 15 feet. Nebraska researchers examined whether crappies display spawning-site fidelity at Sherman Reservoir, a 2,850-acre Nebraska irrigation impoundment known for good fishing. They captured crappies in trap nets from 5 coves in May and marked them with color-coded tags over several years. Adult crappies demonstrated cove fidelity within and among spawning seasons. Over 80 percent of tagged fish were captured in the same cove during the same spawning season, and over 70 percent were recaptured in subsequent years in the same cove. The researchers concluded that crappies sought specific coves in which to spawn, even when similar coves and substrates were available nearby. Another fact to remember is that spawning activity is spread out over a period of time. Female crappie don't all lay eggs at the same time, and an individual female may deposit eggs in batches over a period of two weeks. This assures successful reproduction and provides anglers outstanding shallow-water fishing opportunities for an extended period.
It’s good to see science I participated in. This was a great study. Nic Fryda, now a Wildlife Biologist, has the authorship and at the time was getting his grad degree. I along with many others assisted with daily operations and it was eye opening to see the field results first hand. Very good science indeed.
"Indeed, the single biggest reason we're not catching fish spring, summer, winter, or fall is that there are no fish where we're fishing."
