Biology     Glossary (e.g. epibenthic)

Live close to the sea bed over sandy substrates. Occur in the surf zone of beaches and quiet waters of bays and sandbanks. Are trawled in offshore waters to at least 55 m and possibly deeper. Juveniles may be found in shallow water off white sand beaches, together with accumulations of dead seaweed in the surf zone during spring and summer in Western Australia. Move into shallow waters in large schools during full moon (Ref. 6205). Feed mainly on crustaceans, amphipods, decapods, mysids and copepods. Juveniles consume mostly copepods (Ref. 6223). Oviparous (Ref. 205), and are multiple spawners with asynchronous development (Ref. 12343).

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

S. bassensis is a multiple spawner and spawns asynchronously during the breeding season (Ref. 12343).

Estimates based on models

Preferred temperature (Ref. 123201): 15.2 - 20.5, mean 17.8 °C (based on 100 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00851 (0.00366 - 0.01979), b=3.07 (2.86 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.3   ±0.47 se; based on food items.
Generation time: 4.2 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (K=0.26-0.29).
Fishing Vulnerability (Ref. 59153):  Moderate vulnerability (37 of 100).
Price category (Ref. 80766):   Very high.
