Description synthétique Clés d'identification | Morphologie | Morphométrie

First dorsal fin is absent, pelvic fin reduced (Ref. 44253). Full number of second dorsal, anal and pectoral fin rays is attained about two months after fertilization. Body wall is translucent (Ref. 101247). Scales are absent (Ref. 101248).

Adults ascend rivers in the spawning season without feeding, and dies after spawning. Adults retain larval characteristics, a major factor contributing to its neotenic characteristics is the delayed development of the thyroid system (Ref. 101248). Caught for food.

Life cycle and mating behavior Maturité | Reproduction | Frai | Œufs | Fécondité | Larves

Females spawn in nests under stones (Ref. 101248). The egg clusters are cared for by a male until hatching (Ref. 101248).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00589 (0.00317 - 0.01093), b=2.98 (2.82 - 3.14), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Niveau trophique (Ref. 69278): 3.3 ±0.4 se; based on size and trophs of closest relatives

Résilience (Ref. 120179): Haut, temps minimum de doublement de population inférieur à 15 mois (Preliminary K or Fecundity.).

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

Catégorie de prix (Ref. 80766): Very high.
