Abstract
The 22nd annual Chatham Rise trawl survey was carried out 2–26 January 2013. In total 123 stations were completed - 89 core (200–800 m) phase 1, 2 core phase 2 and 32 deep (800–1300 m). The estimates of relative core biomass were hoki 124 112 t (c.v. 15.3%), hake 1793 t (c.v. 15.3%) and ling 8714 t (c.v. 10.1%). Estimated biomass of orange roughy in core and northern deep strata was 2 776 t (c.v. 32.4%). Acoustic indices of mesopelagic fish were lower than in 2012.
