Adults inhabit small, clear streams with rocky bottoms usually covered with dense mats or clumps of algae (Ref. 28731). This species produces small pyriform eggs, laid on the undersurfaces of stones in freshwater streams. Newly hatched larvae are small (0.12-0.13 cm in notochord length) and poorly developed. These migrate downstream to the sea shortly after hatching at dusk, where they develop as pelagic larvae for 2.5-5 months. Pelagic larvae may potentially disperse to distant islands before migrating to freshwater streams when they reach 1.3-1.4 cm standard length (SL) where they grow further and reproduce (Ref. 95104).

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=0.01122 (0.00514 - 0.02450), b=3.04 (2.87 - 3.21), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Generation time: 0.7 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.

Resiliens (Ref. 120179): Hög, lägsta populationsfördubblingstid mindre än 15 månader (tm=0.5; tmax<2;).

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