简单描述

背的软条 (总数) : 17 - 21; 臀鳍软条: 16 - 20. This species is distinguished from its congeners by the following characters: 2-3 supraneural bones (vs. two); no spinous process (hypurapophysis) on the anterosuperior border of the parahypural bone (hypural complex) (vs. present); sagitta otolith oval with strongly crenulated ventral and dorsal margins (vs. elliptical and smooth-lobed margins in A. crassipinnis while elliptical and smooth-dentate in A. ocellatus), rostrum projected with an elongated process (vs. rostrum process short), posterior region of the otolith rounded (vs. straight or flat), the aspect ratio of sagitta otoliths (AR = 0.665) is higher and the differences are statistically significant at P < 0.05 (vs. AR = 0.606 in A. ocellatus and AR = 0.585 in A. crassipinnis), the roundness index is highest with Rd = 0.597 (vs. Rd = 0.545 in A. ocellatus and Rd = 0.543 in A. crassipinnis) (P < 0.05); morphometric index showed higher values in A. mikoljii (0.837) to A. ocellatus (0.767) and A. crassipinnis (0.735): mean head length of A. mikoljii (36.72% SL) is longer (vs. 35.01% SL in A. crassipinnis and 33.26% SL in A. ocellatus), mean diameter of the orbit 9.06% SL is greater (vs. 7.36%SL in A. ocellatus and 7.73% SL in A. crassipinnis), mean pre-orbital depth 14.22% SL is greater (vs. 0.14% SL in A. crassipinnis) but less than 15.91% SL in A. ocellatus, mean snout length 11.53% SL is longer (vs. 5.36% SL in A. crassipinnis and 10.67% SL in A. ocellatus) (Ref. 126783).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = No PD50 data [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02630 (0.01043 - 0.06634), b=3.00 (2.78 - 3.22), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
营养阶层 (Ref.
69278): 3.0 ±0.4 se; based on size and trophs of closest relatives
回复力 (Ref.
120179): 中等的, 族群倍增时间最少 1.4 - 4.4年 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
