Along these gradients, centrarchids
were generally more abundant in lentic type habitats with lower velocities and greater percentages of silt substrate and vegetation whereas percids were more abundant in shallow lentic habitats such as riffles dominated by cobble and gravel substrate.
The Flier (Centarchus macropterus) is a centrarchid
species largely associated with the southeastern and eastern United States.
Location of infection, % prevalence, mean abundance [+ or -] standard deviation, and range (in parentheses) of infection of parasites from centrarchid
By mapping these measurements onto the centrarchid
family tree, together with data on what each fish eats, the researchers were able to reconstruct how diet and head shape have changed over time.
Body size divergence promotes post-zygotic reproductive isolation in centrarchids
Black-spot caused by Uvulifer ambloplitis (Trematoda) among juvenile centrarchids
in the Piedmont area North Carolina.
We focused on longear sunfish (Lepomis megalotis), the most abundant species of centrarchid
in the Pearl River (Gunning and Suttkus 1990).

In this study, three species of Centrarchid
sunfishes were observed and studied to further learn more about their respective niche in a portion of the Little Harpeth River in Davidson Country, Tennessee.
, cichlids, and cyprinids), and it is possible that D.
In an analysis of stream fish assemblages from 50 undegraded northern watersheds Wang and others (2003) wrote that a diverse assemblage of cyprinids, catostomids, centrarchids
, and percids, like we report in Table 1, existed in warm, wide, gravel-bottomed streams similar to those in our study area.
and percids are about equal in the number of species showing decrease from the past (9) or an increase (7) (Figure 6).
Indices calculated were species richness, number of species of percids, number of species of insectivorous cyprinids, number of species of catostomids, number of species of centrarchids
, number of piscivorous species, number of species of prey, number of families, ratio of number of species to number of families, Shannon's diversity index (Peet, 1974), Hill's evenness index (Peet, 1974), and number of species comprising 75% of total collection.
The seven species of Lepomis and both Micropterus species are centrarchids
