简单描述 型态特徵 | 形态测量图

背的软条 (总数): 173-222; 臀鳍软条: 164 - 208. Most easily distinguished from N. scolopaceus by its pale color; has more postorbital and preopercular pores. Rectangle formed by the lateral line pores is shorter and higher than in scolopaceus. Resembles N. curvirostris in its pale color but the subcutaneous dark bars are not as evident. May be instantly distinguished from curvirostris by the more numerous postorbital and preopercular pores and the much shorter and higher rectangle formed by the lateral line pores. Has smaller teeth than curvirostris.
最容易用它的灰白颜色与 N. scolopaceus 区分了; 有更眼眶后的与前鳃盖骨孔。 由侧线孔形成的长方形更短与更高超过在 scolopaceus 中. 在它的灰白颜色中与 N. curvirostris 相似,但是皮下的深色横带不是一样明显的。 能立即与 curvirostris 区分了藉由众多的眼眶后的与前鳃盖骨孔与比较短与比较高很多长方形由侧线孔形成了。 超过 curvirostris 有较小的齿。

Estimates based on models

Preferred temperature (Ref. 115969): 6.8 - 7.9, mean 7.4 °C (based on 6 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.6270   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00102 (0.00046 - 0.00225), b=3.06 (2.88 - 3.24), in cm total length, based on all LWR estimates for this BS (Ref. 93245).
营养阶层 (Ref. 69278):  3.5   ±0.5 se; based on size and trophs of closest relatives
回复力 (Ref. 120179):  低的, 最小族群倍增时间4.5 - 14 年 (Assuming tmax>10).
Fishing Vulnerability (Ref. 59153):  Very high vulnerability (90 of 100) .
Climate Vulnerability (Ref. 125649):   (0 of 100) .
