Korte beschrijving Determinatiesleutels | Morfologie | Morfometrie

Merodoras is diagnosed from all other doradids by having midlateral plates with medial thorns directed ventrally in adults, and from all doradids except Physopyxis cristata by having an incomplete lateral line. Merodoras also is diagnosed by the unique combination of the following characteristics: pectoral girdle entirely exposed ventrally, with the opening for the arrector ventralis inferior reduced to a small fossae on anterior edge of coracoid; caudal fin truncate; dorsal-fin spine smooth, without serrae; lacrimal serrated; lateral ethmoid serrated (Ref. 58340)

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.02291 (0.00912 - 0.05752), b=2.83 (2.61 - 3.05), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trofisch niveau (Ref. 69278): 2.6 ±0.1 se; based on size and trophs of closest relatives

Weerstandsvermogen (Ref. 120179): Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
