Actinopterygii (ray-finned fishes) > Perciformes
(Perch-likes) > Centrarchidae
Etymology: Lepomis: Greek, lepis = scaled + Greek, poma = gill cover, operculum (Ref. 45335, 79012); gibbosus: gibbosus from gibbous, or like a full moon, referring to body shape (Ref. 1998).
Environment / Climate / Range
Freshwater; brackish; benthopelagic; pH range: 7.0 - 7.5; dH range: 10 - 15; potamodromous (Ref. 51243). Temperate; 4°C - 22°C (Ref. 1672), preferred ?; 50°N - 30°N
North America: New Brunswick in Canada to South Carolina in the USA; Great Lakes, Hudson Bay and upper Mississippi basins from Quebec and New York west to southeast Manitoba and North Dakota, and south to north Kentucky and Missouri. Widely introduced. Several countries report adverse ecological impact after introduction.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 40.0 cm TL male/unsexed; (Ref. 5723); common length : 9.9 cm TL male/unsexed; (Ref. 12193); max. published weight: 630.00 g (Ref. 4699); max. reported age: 12 years (Ref. 72493)
Adults inhabit vegetated lakes and ponds, as well as vegetated pools of creeks and small rivers (Ref. 5723). They feed on small fishes and other vertebrates (Ref. 1998), as well as fish eggs (Ref. 2058). An introduced species in Europe which avoids swift waters and occurs in estuaries with a salinity up to 18.2 ppt (Ref. 59043). Reported in Europe to prey on a wide variety of invertebrates (Ref. 59043). Considered undesirable catch (Ref. 30578).
Males build the nest on very shallow waters near the shore. The pair then swims in a circular path over the nest and eggs and sperm is released in intervals. The male guards the eggs for about 7 days (Ref. 93240) and the young (to about 11 days after hatching), then prepares the nest for another spawning with the same or different females (Ref. 1998). In European waters, each male may spawn with several females in one nest and guard the nest until abandoned by larvae (Ref. 59043). Produces up to 1000 eggs (Ref. 1672).

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01202 (0.00940 - 0.01538), b=3.10 (3.05 - 3.15), based on LWR estimates for this species (Ref. 93245
Trophic Level (Ref. 69278
): 3.3 ±0.1 se; Based on diet studies.
Resilience (Ref. 69278
): Medium, minimum population doubling time 1.4 - 4.4 years (tm=2; Fec=600-5000).
Prior r = 0.46, 2 SD range = 0.21 - 0.99, log(r) = -0.78, SD log(r) = 0.39, Based on: 6 tgen, 1 tmax, 1 Fec records
