Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 53.0 cm TL male/unsexed; (Ref. 5723); common length : 25.0 cm TL male/unsexed; (Ref. 12193); max. published weight: 2.4 kg (Ref. 4699); max. reported age: 10 years (Ref. 12193)
Occurs in sand-bottomed and mud-bottomed pools and backwaters of creeks and small to large rivers, and lakes and ponds. Often found in turbid water (Ref. 5723, 10294). Adult feeds on forage fishes such as shad (Ref. 10294). Younger crappie consumes small invertebrates, including microcrustaceans and small insects (Ref. 10294).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01072 (0.00912 - 0.01258), b=3.08 (3.03 - 3.13), in cm total length, based on LWR estimates for this species (Ref. 93245
Trophic level (Ref. 69278
): 4.4 ±0.6 se; based on diet studies.
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (Assuming tm=2-4; Fec up to 140,000).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (29 of 100) .
