Tab. 2. Results of non-parametric significance test (Kruskal Wallis test) from measures and counts that showed significant differences on averages among the Bryconamericus lethostigmus populations. The B. lethostigmus populations are represented as: ARA = Rio Araranguá; MAM = Rio Mampituba; FOR = Rio Três Forquilhas and MAQ = Rio Maquiné.| Measurements and counts | Kruskal-Wallis chisquared | p-value | Different populations |

|---|
| Pelvic-fin depth | 10.478 | 0.01491 | ARA x FOR |
|---|
| Pectoral-fin length | 10.41 | 0.01538 | ARA x MAQ |

| Pectoral-fin depth | 9.6833 | 0.02146 | ARA x FOR |
