With its white flesh and delicate flavour, ocean perch can be prepared in many ways.
The best cooking methods are grilling and barbecuing, poaching, shallow frying, baking and steaming.

|G;Not subject to overfishing
* Fishing mortality status relates to the level of fishing pressure on a stock – specifically, whether fishing mortality in the year being assessed is likely to result in the stock becoming overfished or prevent the stock from rebuilding from an overfished state. If fishing mortality exceeds either of these thresholds, a stock is considered to be subject to overfishing.
** Biomass status relates to how many fish there are – specifically, whether the biomass in the year being assessed is above the level at which the risk to the stock is considered to be unacceptable. The HSP defines this level as the limit reference point, below which the stock is considered to be overfished.
Scientific name: Helicolenus barathri, H. percoides
- H. barathri: Offshore ocean perch, bigeye ocean perch
- H. percoides: Inshore ocean perch, reef ocean perch, jock stewart
Both are sometimes called coral perch, coral cod, red gurnard perch, red rock perch, red perch or sea perch.
Description: Ocean perch are pinkish-red with poorly defined brown bands on the body (offshore ocean perch) or orange-ish with dark bands on the body and small dark spots on the head (inshore ocean perch). They have a low spineless ridge running horizontally below the eye. Ocean perch have a few series of small spines on the top of the head and along the edge of the operculum (the hard bony flap covering the gills). The dorsal spines are venomous.
Size (length and weight): Depending on species, up to at least 40 cm (offshore ocean perch) or 30 cm (inshore ocean perch) in length and 1.4 kg.
Life span: Potentially up to 60 years.
Habitat: Ocean perch are a benthopelagic species that inhabits flat, hard seabeds on the continental shelf and upper slope. Inshore ocean perch is often found at depths of 80-350 metres. Offshore ocean perch is often found at depths of 250-350 metres.
Prey: Large benthic invertebrates such as squid, small fish (e.g. cardinal fish) and benthic crustaceans (e.g. royal red prawns).
Predated by: Sharks and marine mammals such as seals.
Reproduction: Females reach reproductive maturity at about 5 years of age, with male ocean perch reach maturity at 5-7 years of age. Spawning occurs over an extended period from winter to early summer, in June for reef ocean perch and slightly later for bigeye ocean perch. Spawning is distinctive in that fertilisation and larvae development is internal (i.e. ocean perch are lecithotrophic viviparous). Females produce 150 000‑200 000 eggs per spawning season. Larvae are extruded in floating jelly-like masses when they reach about 1 mm in length. Once extruded, the jelly-like mass dissolves to release the larvae. Inshore ocean perch are thought to retain larvae for longer than offshore ocean perch.
Other notes: Both species are found in Australia and New Zealand but there have been recent conflicting conclusions as to whether they are actually separate species.

The Commonwealth catch of ocean perch is managed by quota. Which means the catch of this fish by commercial fishers is restricted by weight.
Inshore ocean perch and offshore ocean perch are managed under a single total allowable catch, however both species are assessed separately. Catch limits are set every three years and restrict the weight of fish that can be taken by commercial operators.
Commercial fishermen are required to fill in records of their catches, during each fishing trip and when they land their catch in a port. This helps us keep records of how much is being caught.
AFMA decide on the amount that can be caught each year from expert advice and recommendations from fisheries managers, industry members, scientist and researchers.
Offshore ocean perch are caught at depths between 235-1100 metres along the south east coast of Australia with a separate population along the south west coast of Western Australia.
Inshore ocean perch are found on coastal rocky reef from the Queensland/New South Wales border to the south west coast of Western Australia and are caught in depths between 10-425 metres.
Fishers use trawl nets and danish seine nets to catch ocean perch.
Sometimes, bottom trawling can catch unwanted species of fish (not the type of fish the net was supposed to catch). This is known as bycatch and it is monitored by on-board fishery observers who assess the environmental impact of the trawling.
Although it is not physically possible to trawl on reef structures, significant long-term damage can occur if sensitive habitat areas like corals, sponges and seagrass beds are trawled. To ensure these sensitive habitat areas are protected from trawling, management arrangements such as area closures are extensively used.
The danish seine method of fishing has minimal impacts on the environment as it does not come into contact with the seafloor.
AFMA carries out ecological risk assessments (ERA) for all of its major fisheries. The impact of bottom trawl nets on bycatch species and habitats has been assessed as part of the ERA. AFMA mitigates or reduces that impact through its ecological risk management (ERM) strategy. The ERM details a number of management arrangements and strategies which aim to reduce the impact of fishing on the environment. In the Commonwealth Trawl Sector, this includes minimum mesh sizes for otter trawls to reduce the catch of small and juvenile fish, mitigation devices to reduce interactions with threatened, endangered and protected species and spatial closures to protect vulnerable species and habitats.
