Biology     Glossary (e.g. epibenthic)

Adults occur in brackish estuaries, river mouths and freshwater creeks (Ref. 2847, 48637, 44894). Found in the lower courses of rivers, often upstream from the tidal zone (Ref. 12693). Young are usually found while wading in rocky creeks near the coast (Ref. 2847). Marketed fresh (Ref. 12693).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.7500   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00832 (0.00406 - 0.01705), b=3.00 (2.81 - 3.19), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic Level (Ref. 69278):  3.3   ±0.55 se; Based on food items.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low to moderate vulnerability (35 of 100) .
