Biologia     Glossário (p.ex. 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).

Ciclo de vida ou comportamento de acasalamento Maturities | Reprodução | Spawnings | Egg(s) | Fecundities | Larvas

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 based on models

Índice de diversidade filogenética (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00933 (0.00422 - 0.02065), b=3.01 (2.82 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Nível Trófico (Ref. 69278):  3.1   ±0.42 se; based on food items.
Generation time: 8.2 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.
Resiliência (Ref. 120179):  Baixo, tempo mínimo de duplicação da população 4,5 - 14 anos (K=0.13-0.27; tmax=12).
Fishing Vulnerability (Ref. 59153):  Moderate vulnerability (39 of 100).
Categoria de preço (Ref. 80766):   Unknown.
Nutrients (Ref. 124155):  Calcium = 95.8 [63.6, 169.1] mg/100g; Iron = 1.51 [1.02, 2.14] mg/100g; Protein = 18.4 [17.6, 19.1] %; Omega3 = 0.694 [0.335, 1.511] g/100g; Selenium = 29.9 [13.5, 63.4] μg/100g; VitaminA = 36 [16, 88] μg/100g; Zinc = 1.17 [0.87, 1.58] mg/100g (wet weight);
