Description: White warehou is the deepest ranging of the three warehou species in New Zealand and is common in southeastern waters and on the Campbell Plateau in the Subantarctics. It is mostly taken as a bycatch in bottom trawl fisheries for hoki and silver warehou.
Ecological concerns: The absence of some basic biological information about white warehou, the absence of a quantitative stock assessment, the unknown stock size, the uncertainty over stock boundaries and the unknown sustainability of recent catch levels. There are also concerns about past mis-reporting of white warehou as silver warehou catches, plus there is no management plan. Bottom trawling causes considerable damage to seafloor communities and, due to white warehou being a bycatch species of other fisheries, it is also associated with the bycatch of seabirds, marine mammals and other non-target fish.
Economic value: White warehou is sold in New Zealand and Asia.
