deep-sea perch, rarely surfaces alive

Size
Length: 25–35 cm, Weight: 300–600 g
Lifespan
15–20 years
Diet
Small fish, squid and crustaceans. Hunts near the seafloor using a large, spiny head. Uses its large eyes to detect prey in low light. Feeds most actively at night. Swims with a slow, hovering motion.
Habitat
Sandy and rocky bottoms in coastal waters from 20 to 200 metres depth. Prefers areas with mixed substrate and moderate currents. Often found near rocky reefs, drop-offs and submarine canyons.
Range
Coastal waters of the North and South Islands from Northland to Stewart Island. Most common on sandy and rocky bottoms of the continental shelf. Also found in southern Australia and the Southwest Pacific.
Endemism
Native
Main Threats
Bycatch in bottom trawl and set net fisheries is the primary threat. Habitat damage from bottom trawling on rocky reefs. Slow reproduction makes populations vulnerable. No targeted commercial fishery exists in New Zealand waters.
Population
Populations are considered stable across most of the range. Caught as bycatch in snapper, tarakihi and other bottom-dwelling fisheries. Quota management limits total bycatch. Better species-specific data is needed for accurate stock assessments.
Conservation Status
Not Threatened
A member of the scorpionfish family, armed with venomous spines on its dorsal, anal and pelvic fins. The scarpee looks unremarkable. It is a pinkish-orange fish with a large spiny head and big eyes. But touch those spines and you will regret it. A sting causes intense pain, swelling and numbness that can last for hours. The defence is effective. The warning is physical. The consequence is immediate. Pain is the teacher. Memory is the lesson. Caution is the result. Despite this defence, the firm white flesh is highly regarded. In fish shops, scarpee is often called sea perch or Jock Stewart. These names hide its venomous nature. The consumer is unaware. The risk is concealed. The label is generic. The reality is sharp. Handling requires care. The injury is painful. The meat is prized. The paradox is commercial. The danger is real. The reward is culinary. The balance is delicate. The Māori name Pohuiakaroa reflects its association with rocky reefs and deep water. Several similar species live in New Zealand waters. All possess venomous spines. The distinction is taxonomic. The danger is shared. The appearance is similar. The caution is universal. The knowledge is traditional. The name is specific. The habitat is defined. The depth is significant. The scarpee hunts near the seafloor at night. It uses those large eyes to detect prey in low light. Small fish, squid and crustaceans form the diet. A slow, hovering motion characterises its movement near the bottom. It waits for something to drift past. The spiny head is not just for defence. It helps the fish wedge itself into crevices during the day. The morphology is multifunctional. The structure provides shelter. The strategy is passive. The survival depends on concealment. Populations are considered stable. Better species-specific data is needed for accurate stock assessments. The scarpee is caught as bycatch in bottom trawl and set net fisheries. It targets snapper, tarakihi and other bottom-dwelling species. A venomous fish with good eating. A paradox of the deep shelf. The capture is incidental. The value is hidden. The management is reactive. The data is sparse. The future is uncertain. No one told it otherwise.
