Краткое описание определительные ключи | морфология | морфометрия

колючие лучи спинного плавника (общее число) : 16; членистые (мягкие) лучи спинного плавника (общее число) : 9 - 10; колючие лучи анального плавника: 6 - 7; членистые (мягкие) лучи анального плавника: 8 - 9; позвонки: 26. This relatively elongated species which reaches more than 12 cm TL, is distinguished from all species except A. kaaygua in having a modal count of 12 pectoral fin rays; differs from A. facetus, cf. facetus, and guarani, by having modally 6 C1 gill rakers; differs facetus in not having an upwards directed mouth and a longer dorsal fin scale cover, covering bases of 7-8 last spines (vs. only 2-3). The same as A. kaaygua, it has yellowish ground color, but without the red corners of caudal fin (present in kaaygua, and also differs by being much less deep-bodied. Distinguished from all its congeners by pink to red dominant males (Ref. 74689).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.1   ±0.4 se; based on size and trophs of closest relatives
устойчивость к внешним воздействиям (Ref. 120179):  средний (среднего размера), минимальное время удвоения популяции 1.4-4.4 года (Assuming Fec<1000).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
