Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:Bearded Silverside occur in loose aggregations in the photic zone and are found in tidepools, rocky reefs, along rocky shorelines and reef margins. Eggs of this species are large and self adhesive. This species has a depth profile of 0-6 m.
Congregatory:Congregatory (and dispersive)

Use and Trade [top]

Use and Trade: This species is used as bait.

Threats [top]

Major Threat(s): There is no directed commercial fishery for this species. It is infrequently collected for use as bait, however this is unlikely to be driving a significant population decline. This species is likely to be undergoing localised declines in areas of coastal development and urban pollution discharge.

Conservation Actions [top]

Conservation Actions: There are no species-specific conservation measures in place, or needed, for this species. However its distribution is likely to coincide with a number of marine protected areas.
