silver warehou, mid-water and commercial

Size
Length: 40–60 cm, Weight: 1–3 kg
Lifespan
10–15 years
Diet
Feeds on salps, crustaceans, squid and small fish. Filters salps from water column using fine gill rakers. Hunts actively for larger prey when available. Feeds throughout water column depths.
Habitat
Mid-water and surface waters from inshore bays to edge of continental shelf. Typically found between 20 and 400 metres depth. Prefers temperate waters with high plankton productivity levels.
Range
Temperate waters around New Zealand from Northland to Campbell Plateau. Most common on Chatham Rise and off east coast of South Island. Also found in southern Australia and Chile globally.
Endemism
Native
Main Threats
Commercial trawl fisheries are primary threat. Bycatch in hoki and squid fisheries impacts stocks. Climate change affects salp populations. No significant recreational fishing pressure. Often caught with blue warehou.
Population
Populations managed under New Zealand's quota management system. Caught mainly as bycatch in hoki fishery. Stock assessments indicate stable populations with sustainable harvest levels. Regular monitoring ensures appropriate catch limits.
Conservation Status
Not Threatened
Sleek and silvery with small dark spots on the upper body. The silver warehou is also called the spotted warehou. The name describes exactly what is seen. It is a close relative of the blue warehou. But it lives in slightly shallower water. A fish that likes the light a little more. The preference is subtle. The distinction is visible. The spots mark the identity. The colour reflects the environment. The diet is salps. Gelatinous barrel-shaped creatures drift through the ocean. They filter plankton from the water. Silver warehou filter salps from the water column. They use fine gill rakers. This is a specialised adaptation for a specialised diet. It gives the flesh a distinctive flavour. The texture is soft. A fish that tastes like what it eats. The connection is direct. The consumer becomes the consumed. The quality is derived from the source. The salp defines the meal. A common sight in fish and chip shops across the country. The Māori name Warehou is shared with the blue warehou. It applies to several other related species. This reflects their importance as food fish. They are not glamorous. They are not expensive. Just good, honest eating. The value is practical. The appeal is universal. It feeds the family. It fills the plate. It does not demand attention. It delivers sustenance. The reputation is solid. Not flashy. Reliable. Populations are managed under New Zealand's quota management system. Silver warehou are caught mainly as bycatch in the hoki fishery. Stock assessments indicate stable populations. Harvest levels are sustainable. The management works. The data supports it. The fishery continues. The balance is maintained. The bycatch is tolerated. The target is hoki. The warehou is incidental. But it is valuable. It contributes to the yield. It supports the industry. A spotted, silvery fish with a taste for salps. It holds down the middle of the fish counter. It feeds families who want a good feed without breaking the bank. That is the silver warehou. And that seems to be enough. The role is modest. The impact is significant. It provides protein. It offers affordability. It remains accessible. The status is secure. The future is stable. It swims on. The spots remain. The silvery scales flash. The net captures it. The shop sells it. The table receives it. The cycle completes. No drama. No scarcity. Just presence. It carries on.
