Springtime is crappietime. From Florida to Ontario, anglers eagerly await the arrival of slabs in shallow water. As the spawn approaches, males don their dark courting colors. They bite like tigers, especially after they select a spawning site and begin clearing a nest and defending it. Females can remain edgy, but they often bite carefully presented baits quite well. The fishing is relatively easy, a day on the water often ending with a meal or two of one of the most succulent tastes freshwater offers.

Water temperatures around the upper-50°F to 60°F range begin to bring crappies shallow into spawning areas. Peak spawning activity generally occurs at water temps of 68°F to 72°F for both black and white crappies. In southern waters, spawning may begin in late February, while in the northern tier of the crappie’s range, early June is more typical.

The spawn is a relatively brief and variable period. In smaller bodies of water, the bulk of spawning may occur within about a 2-week window. In huge reservoirs and sprawling lakes, which might encompass slightly different climates between two distant ends of the lake, the Spawn Period could last a month to six weeks. In Lake of the Woods on the Minnesota-Ontario border, for example, crappies in the far southern part of the lake finish spawning while those in the far northern portion are still in prespawn mode.

Crappies generally choose deeper water and thicker cover for spawning than other members of the sunfish family, depth affected by water clarity. In average clarity, crappies generally spawn at about 3 to 6 feet. In muddy conditions, the bulk of the spawn may take place in water less than 2 feet deep. Light penetration down to the depth of eggs provides warmth for optimum development. If the hatch is delayed, survival can be affected, and poor light conditions can interfere with feeding of larval crappies.

Bays, coves, creek arms, and backwaters with ample cover and the right substrates draw the most crappies. In natural lakes, vegetation—cattails, bulrushes, sedges, and lilypads—keys crappie location, and in reservoirs submerged brush and stumpfields are prime.

Nest Building

Nest building by male crappies usually begins as water temperature reaches about 60°F to 65°F. Groups of males move into a reedbed or stumpfield and establish spawning territories. By this time males have turned dark as hormonal changes begin to occur. Females, holding on the perimeter of the spawning area, have usually darkened, although not as dark as males. Females are distinctively plump, bloated with ovaries full of eggs.

Within the larger territory, males sweep nests over substrates made of marl, gravel, or silt, with firmer substrates generally preferred. Nests are 8 to 12 inches in diameter and tend to be circular or oblong. Nests lack the distinctive perfect circle pattern of bass and bluegills, and rarely feature a distinct lip or rim.

As females approach spawning areas, individual males herd them into their territories and eventually over the nest. Spawning pairs bump their abdominal areas together for a few seconds and release eggs and sperm. The dance may be repeated up to dozens of times over the course of a few hours, or the whole spawn for a pair might conclude after only about 20 minutes.

Eggs are adhesive and slightly less than a millimeter in diameter. After spawning the female moves on and can be driven over another nest when she enters the territory of another male. Females might spawn in several nests by the time her eggs are spent. Multi-nest spawning can help ensure continued genetic diversity within populations and that at least some eggs of each female hatch.

If spawning habitat is limited, crappies from different areas of the lake may wash over it in waves. The first to arrive spawn earliest, perhaps in the low-60°F range, and, as other areas of the lake warm at varying rates, more crappies continue to appear and spawn in the same area. This might leave the impression that the spawn is a long drawn-out affair for individual fish, but that isn’t the case. Each individual female generally finishes her duties within a day.

Spawning concludes as females move to post-spawn positions. In a natural lake, weededges along dropoffs usually key location. In reservoirs, crappies move to timber or brush cover along creek channels in major creek arms.

Males guard nests, fanning eggs frequently to keep them oxygenated and clean until they hatch, which can take about 2 days at 70°F but several days at cooler temperatures. Post hatch, males may remain several days to guard the fry eventually moving to deeper cover to group with females. Fry feed on zooplankton in the shallows, ultimately transitioning to open water where they drift for the first summer, continuing to feed on zooplankton and other invertebrates, or even small fish depending on how big the young crappies are.
