MFish chief executive John Glaister measures hoki in the wet lab on RV Kaharoa.

In the acoustics lab: voyage leader Richard O’Driscoll explains survey procedures.

NIWA’s 28-metre RV Kaharoa recently conducted a six-week acoustic survey of spawning hoki in Cook Strait. This involved nine sub-surveys or ‘snapshots’ of the main spawning ground. The survey was the twelfth in a time-series of acoustic estimates of hoki abundance in Cook Strait, and the results are vital to establish the status of the Cook Strait fishery. During one leg of the trip, MFish chief executive John Glaister proved himself a dab hand in the wet lab.
