Bunnell, D.B., González, M.J. and Stein, R.A., 2003. Zooplankton biomass enhances growth, but not survival, of first-feeding Pomoxis spp. larvae. Canadian Journal of Fisheries and Aquatic Sciences, 60(11), pp.1314-1323.
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 |
