Species Development state Trait Primary Data Secondary Data
Pomoxis annularis Egg Incubation time Adults of both species spawn for 6–8 weeks during late spring through early summer, exhibiting similar reproductive strategies as males build nests in the littoral zone (0.2- to 0.8-m depth) and then provide nest defence to incubating eggs (2–4 days) and embryos (i.e., yolk-sac larvae, 2-6 days). 4.0 days
Pomoxis annularis Larvae Initial larval size In a compilation by Auer (1982) of 99 freshwater species (including 22 families) native to the Great Lakes basin, mean length at hatch was 6.24 mm; white crappie was the smallest species 6.24 mm
Pomoxis annularis Larvae Sibling intracohort cannibalism Potential predators of larvae are numerous, including earlier-hatched larvae, such as cannibalistic Pomoxis spp. larvae, or limnetic walleye and yellow perch, as well as otherlimnetic adults such as white crappie. Cannibalism
Pomoxis annularis Larvae Full yolk-sac resorption Adults of both species spawn for 6–8 weeks during late spring through early summer, exhibiting similar reproductive strategies as males build nests in the littoral zone (0.2- to 0.8-m depth) and then provide nest defence to incubating eggs (2–4 days) and embryos (i.e., yolk-sac larvae, 2-6 days) 112.0 °C * day
Pomoxis annularis Larvae Onset of exogeneous feeding Growth of first-feeding larvae (<10 days old) increased with total zooplankton biomass (r2 = 0.64). 10.0 °C * day
