Ecology

Habitat

Habitat and Ecology

Habitat and Ecology
A small species, to about 126 mm SL. Inhabits rocky areas in depths of about 10-40 m (B. Russell pers. comm. 2008).
In Jurien Bay Marine Park, occurring on deeper more exposed reefs (> 10 m), closely associated with the substrate, among red algae, turfs and ledges (Fairclough et al. in prep). Biological data from a few individuals collected on mid-west coast of Australia suggests protogyny, e.g. differential size range of females and males and sexual dichromatism, coupled with histological analyses of gonads (males contain secondary testes), but not confirmed/conclusive at this stage (Fairclough, D. unpublished data).

Species is common in shallow water in Western Australia (to about 20 m), but tends to be in deeper water (to 40 m) in sponge habitats elsewhere (B. Russell pers. comm.2008).

Justification
Little is known of the population and life history characteristics (limited biological data). However, this species is abundant where studied, is widespread and there are no apparent threats. It is therefore listed as Least Concern.

Population

Population
Presumed continuous distribution in Western Australia. Semi-quantitative underwater visual census (UVC, timed swims) of Hutchins (2001) found A. maculatus to be frequent or abundant at seven locations surveyed between the Houtman Abrolhos Islands (ca 28-29°S, 114°E) and Esperance (34°S,122°E) in Western Australia. Quantitative UVC (measured transects) within the Jurien Bay Marine Park (ca 30-31°S, 115°E) confirmed this species to be relatively abundant at that location, occurring on deeper more exposed reefs (> 10 m), closely associated with the substrate, among red algae, turfs and ledges (Fairclough et al. in prep). Harvey et al. (2004) also found A. maculatus to be abundant over reef habitats at Esperance. The population is probably stable.

Management

Conservation Actions

Conservation Actions
There are no specific conservation measures in place for this species. However, in Western Australia, South Australia and New South Wales, several marine parks have recently been established or are being established within its range and comprise “no fishing” areas. However, those areas typically represent a relatively small proportion of the area of those MPAs. Furthermore, trophic linkages to this species are relatively poorly understood and thus flow on effects of protection afforded to its predators by those “no fishing” zones is unknown.
