Wed 19 Feb 2020:1931 Earthquake Commemorative Lecture Unlocking the secrets of the Hikurangi subduction zone

Have you ever wondered about that sleeping giant that lies beneath Hawke’s Bay, known as the Hikurangi subduction zone? Dr Laura Wallace will discuss the results of scientific studies that reveal what the subduction zone is currently up to, include the latest on the “slow-motion earthquakes” that occur regularly in the Hawke’s Bay and Gisborne regions, and what we have learned about them by placing monitoring instruments on the seafloor. Laura will also assess the earthquake and tsunami potential of the Hikurangi subduction zone, and describe a number of recent international and New Zealand-led missions aimed at better understanding our sleeping giant.

Dr Laura Wallace is a geophysicist at GNS Science in Lower Hutt, with a joint position at the University of Texas. Much of her scientific career has focused on investigating New Zealand’s largest fault, the Hikurangi subduction zone. She is currently leading a multi-national effort to better understand the hazards it poses.

Evolution of fish harvesting technology has focussed on minimising cost and optimising extraction selectivity, i.e. minimising unwanted catch. Because of the sustainable limits of the fishery, our fishing industry is now at the point where increased value can only come from maximising fish utilisation. To achieve this we must be increasingly sophisticated about how we manage and harvest our limited resources. Fishing technology has evolved to the point where we are able to control many aspects of the harvesting process; but where to apply the control to maximise fish value?
 
From our research in the 1990s on King salmon (a model species for understanding the effects of harvesting on post-harvest quality), we developed a new fish-centric, quality-focussed, rested harvesting process. We applied the same approach to NZ’s largest wild fishery (hoki).
 
Development of a Modular Harvesting System (MHS,  which replaces the conventional gear of a trawl), focussed on delivering low-damage, low-fatigue capture of wild fish and the unharmed escape and release of unwanted catch. Commercialisation of this technology has been at the centre of the Primary Growth Partnership-funded Precision Seafood Harvesting (PSH) programme.
 
This presentation will look at the background, underlying principles and development of the technology, and how fish-focussed industrial fishing technology is not only feasible, but great business.
