Helicolenus percoides
Red gurnard perch
Distribution
Temperate Australasia
Description
Differs from local gurnard perches in having three brown bands across the body and fewer spines on the cheek. Adults are most abundant in deep waters on the continental slope, with smaller animals more common on the continental shelf, where they are trawled commercially. Juveniles also sometimes occur on much shallower Tasmanian reefs adjacent to deep water.
Information
Max Size: 47 cm
Sea Temperature Range: 10.4-19.3°C
Depth: 10-750
Habitat Generalization Index: N/A
Also referred to as the SGI (Species Generalisation Index), this describes the habitat niche breadth of the species. Species with values less than 15 are found in a relatively narrow range of reef habitat types (specialists), while those over 25 may be found on most hard substrates within their range (generalists).

Conservation and Rarity
IUCN Status: Not Evaluated
Occurrence: Rare (1.0% of sites)
Occurrence describes how often the species is found on surveys within its distribution. It is calculated as the % of reef sites surveyed by RLS divers across all the ecoregions in which the species has been observed
Abundance: Solitary (1 per transect)
Abundance is calculated as the average number of individuals recorded per RLS transect, where present.
