Bayesian length-weight: a=0.02512 (0.01226 - 0.05148), b=2.96 (2.79 - 3.13), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic level (Ref. 69278): 4.1 ±0.60 se; based on food items.

Daya lenting (Ref. 120179): sedang, Waktu penggandaan populasi minimum 1.4 - 4.4 tahun (K=0.18-0.28).

Fishing Vulnerability (Ref. 59153): High vulnerability (57 of 100).

kategori harga (Ref. 80766): Very high.
