Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Anal spines: 0; Vertebrae: 145 - 159. Snout long; eye diameter 2-2.5 times in snout length; posterior nostrils much closer to eyes than to anterior nostrils; mouth very large; teeth generally large and conspicuous (Ref. 4832). Head broader, interorbital about 8 times in head; lateral-line pores before anus 44-47; dorsal-fin rays before anus 66-78; vertebrae 145-159 (Ref. 9830).

Occurs from the littoral zone to the upper bathy-benthic region (Ref. 9942, 11230). Inhabits soft bottoms (Ref. 11230), also found in estuaries. Sometimes enters freshwater environment (Ref. 9987). Feeds on small bottom fishes and crustaceans. Captured and cultured for fishery in Japan. Marketed mainly fresh (Ref. 7238). Also used as bait for shark fishing (Ref. 2872). Also caught by bag (dol) nets. Used in Chinese medicine (Ref. 12166).

Estimates based on models

Preferred temperature (Ref. 115969): 11.6 - 23.2, mean 17.4 (based on 401 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00437 (0.00171 - 0.01116), b=3.07 (2.85 - 3.29), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.4 ±0.67 se; based on food items.

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Tmax=15; K=0.19-0.33; Min Rel Fec=153).

Prior r = 0.57, 95% CL = 0.37 - 0.85, Based on 3 data-limited stock assessments.

Fishing Vulnerability (Ref. 59153): High vulnerability (62 of 100).

Climate Vulnerability (Ref. 125649): Very high vulnerability (85 of 100).

Price category (Ref. 80766): Very high.
