Why is it on the red list?   Biology

1. The fishery has concerning levels of bycatch of juvenile fish, endangered and threatened albatross, basking sharks and fur seals.

2. New Zealand hoki stocks are declining, and there is no formal rebuilding plan in place.

3. Bottom trawling is highly destructive to benthic ecosystems. Trawling for hoki takes place in sensitive, deep-water habitats such as seamounts.

New Zealand Hoki are found most abundantly between 200 and 600 metres below sea level, but can live at depths up to 1000 metres.

Hoki live up to 25 years and mature between the ages of four and five years.

The largest hoki measure up to 1.3 meters and weigh up to seven kilograms.

Hoki feed on fish, crustaceans and squid.
