About blue cod

Blue cod are:

  • bottom-dwelling fish found at depths of up to 150m
  • only found in New Zealand waters
  • more abundant south of Cook Strait and around the Chatham Islands.

Blue cod growth is influenced by a range of factors, including sex, habitat and local fishing pressure. They can change sex from female to male and males are generally larger than females.

Fishing rules for blue cod and other fish species differ around the country and can change. Check the rules for your area every time before you go fishing.

The blue cod fishery

The blue cod fishery is split into 8 fishery management areas. Catch allowances are set differently for each area depending on the health of the fish population and fishing pressure.

 

 

2016 catch allowances (tonnes)

Blue cod are managed under New Zealand's Quota Management System (QMS). By controlling the amount of fish taken from each area, the QMS helps keep fisheries sustainable.

Blue cod (BCO 3) catch per unit effort from 1990 to 2014

Recreational fishers catch most blue cod in BCO 3. In the 2011-2012 fishing year, almost 120 tonnes of blue cod were caught by recreational fishers in BCO 3. Commercial catch averages around 160 tonnes a year.

Blue cod are mostly caught in pots – and stock levels are measured using a method known as "pot catch per unit effort" (CPUE).  The graph shows stock has fluctuated in a narrow band since the early 1990s but has stayed above soft and hard management limits. If stock falls below a soft limit, MPI manages the fishery to rebuild stock. If stock falls below a hard limit, MPI closes the fishery.
