Biology     Glossary (e.g. epibenthic)

Occurs in impoundments and rivers. Prefers clear-flowing waters over sandy or rocky substrates. An omnivorous bottom feeder. Diet includes water fleas, snails, plankton, small mussels, insects, small fish, algae and detritus. Breeds in spring through to midsummer after the first substantial rains of the season. Migrates upstream to spawn over suitable gravel beds (Ref. 7248).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Breeds in flowing water therefore must ascend the rivers to spawn in gravel beds. Eggs are laid in a shallow saucer-like nest which is constructed in the gravel by a female (or perhaps male) using the snout and caudal fin. Eggs are covered with gravel after fertilization. A 45 cm female carries 30, 000 eggs.

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01122 (0.00533 - 0.02363), b=2.98 (2.81 - 3.15), based on LWR estimates for this Subfamily-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.1   ±0.42 se; Based on food items.
Resilience (Ref. 69278):  Low, minimum population doubling time 4.5 - 14 years (K=0.13-0.27; tmax=12).
Vulnerability (Ref. 59153):  Moderate vulnerability (39 of 100) .
Price category (Ref. 80766):   Unknown.
