Short description पहचान कुंजी | आकृति विज्ञान | मौरफोमैटरिक्स

This species possess a longer body, smaller interorbital space (equal to that of the mouth width which is 0.78-0.82 times the pre-oral length); short caudal fin; differently-proportioned first dorsal fin (interdorsal space, 24.6% to 25.8% of TL); relatively short snout; prenarial length 0.64-0.69 times mouth width and 1.32-1.59 times eye length; denticles wide, tricuspidate, overlapping, and rhomboid; caudal 'bar' present at the fork of the caudal fin; dorsal caudal lobe wide, and a broad rounded tip (Ref. 120195).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00347 (0.00165 - 0.00730), b=3.09 (2.92 - 3.26), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.3 ±0.3 se; based on size and trophs of closest relatives

लौटाव (Ref. 120179): निम्न, न्यूनतम जनसंख्या दुगनी होने का समय 4.5 - 14 वर्ष। (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (49 of 100).
