Maximum likelihood tree of Doradidae inferred from analysis of combined 12S, 16S and EF1a (exons + introns) sequence data. Numbers at nodes represent percentage Bayesian posterior probabilities, ML bootstrap (500 pseudoreplicates) and MP bootstrap (1000 pseudoreplicates). This is an unrooted tree; the black star indicates the hypothetical attachment point of the root (see Fig. 7).

The Troutperch, Percopsis omiscomaycus (Walbaum), is so named because of its troutlike appearance with a free adipose fin, but perchlike (Percopsis means perchlike) in having ctenoid scales and spines in the fins (Figs. 20.1 and 20.2). The specific epithet (omiscomaycus) is attributed to an Algonkian language name, which includes the root for the word trout (McPhail & Lindsey 1970).

Maximum likelihood tree of Doradidae inferred from nuclear EF1a intron and exon sequence data. Numbers at nodes represent Bayesian posterior probability percentages, ML bootstrap (500 pseudoreplicates) values, MP bootstrap (1000 pseudoreplicates) values. Nodes without support values represent <50% support obtained by each method (Bayesian, ML, MP). This is an unrooted tree; the black star indicates the hypothetical attachment point of the root (see Fig. 7).

Unrooted maximum parsimony trees of Doradidae inferred from molecular and morphological data. (A) Molecular tree based on 3833 bp of 12S, 16S and EF1a exons + introns sequence data; the black star indicates the hypothetical attachment point of the root (see Fig. 7). (B) Morphological tree based on 95 morphological characters (Higuchi, 1992); the black star indicates the hypothetical attachment point of the root (see Fig. 1). Numbers at nodes are bootstrap percentages based on 1000 pseudoreplicates. Support values <50% are not shown.
