Key Facts

  • New Zealand deepwater trawl fisheries catch multiple species of oreodories, which are a group of long-lived, slow growing and deep-sea fish that are vulnerable to overfishing.
  • There is serious concern some stocks are overfished in NZ.
  • Oreodories are caught using deep-sea bottom trawlers, which damage deep-water habitat that supports slow growing communities (such as corals). These affected habitats are extremely sensitive to disturbance and could take centuries to recover.

The name ‘oreodory’ refers to a group of species that can live to over 100 years, are slow-growing and tend to inhabit deep-water areas. New Zealand fisheries catch multiple species of oreodory, which are managed together rather than as separate species. This can make it challenging to identify if there are issues in the stock of a single species. Little is known about their biology, and little investment has been made by either country into updating out-of-date stock assessments or filling the gaps for unmeasured stocks.

Oreodories are both targeted by commercial fishing operations and caught as bycatch in fisheries targeting orange roughy.

There are serious concerns that some stocks in NZ are overfished, or being fished too heavily.  Fishery managers have responded by setting cuts to the amount of catch allowed in some areas to take some pressure off stocks; due to the species’ long life history, it is unclear whether these management measures will be successful in supporting the rebuilding of these populations.

Oreodories are caught using deep-sea bottom trawlers over seamounts.  Research has identified that deep-water marine habitats support species that are generally slow growing and highly sensitive to disturbance, in particular, deep-water corals. Recovery from the impacts of trawling on deep-sea habitats could take centuries.
