Short description
Morfologi | Morfometri
Mjukstrålar i analfenan: 9 - 11. Distinguished from its congeners by having posterior extremity of maxilla irregularly serrated; opercle, subopercle, interopercle, cleithrum and postcleithrum serrated. Differs further by the following combination of characters: posterior border of maxilla reaching anterior border of orbit; 4 (occasionally 3) predorsal bones; no supernumerary spine on first dorsal pterygiophore; 4th or 5th dorsal fin spine longest; 15-17 pectoral fin rays; 9-11 anal fin rays; 44-48 caudal fin rays; procurrent spur absent (Ref. 55324).

50 = 0.5312 [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).
Trofisk nivå (Ref.
69278): 3.5 ±0.1 se; based on size and trophs of closest relatives
Resiliens (Ref.
120179): Hög, lägsta populationsfördubblingstid mindre än 15 månader (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
