Precision Seafood Harvesting (PSH)

Precision Seafood Harvesting (PSH)

Starting Out

PSH is the commercialisation phase of nearly ten years of New Zealand research.  Three major New Zealand fishing companies; Aotearoa Fisheries, Sanford and Sealord are investing $24 million between them into the programme with the other half of the funding coming from the Ministry for Primary Industries (MPI), which is matching the industry investment under a Primary Growth Partnership.

The technology has been hailed as the future of commercial fishing.  Driven by the desire within industry to increase the survivability of unintended catch (juvenile fish and by-catch species), and take better care of the fish being caught, PSH does away with traditional trawl nets to allow fish to be landed on boats alive and in perfect condition, while safely releasing undersized fish.  The Modular Harvest System (MHS) technology, that has been designed and tested as part of the Precision Seafood Harvesting programme, represents Stage One of a three-stage development.  The programme will lead to changes in vessel designs and layouts, how we handle fish and get it into the market place.  It’s about future of our seas – helping to ensure our oceans are full of life.

A “new way to fish,” this potential replacement for traditional trawl nets is essentially a large, flexible PVC liner with specifically sized holes along its length that allow undersized fish to escape before they are even brought on board a fishing vessel.

Benchmarks of Success

  • The numbers

The first stage potential survivability rates of the fish being caught are even better than expected – for example:  .The second stage will be to develop and commercialise new on-board fish handling technologies that will maintain these survival rates through the sorting and grading of commercial catch quantities.

  • To market, to market

This technology means the industry can offer more great quality fish to consumers and there are new opportunities for higher end product. It all increases the value of the products on offer and in turn, the value of the industry. The story of how the fish is caught is increasingly important for consumers and this new method is a great New Zealand story, that will potentially change the way the world fishes.

  • Industry recognition

Precision Seafood Harvesting has already won multiple awards for innovation including the Supreme Award and the Innovation in Sustainability & Clean-Tech Award at the 2014 NEW ZEALAND INNOVATOR AWARDS and two major categories at the 2014 KiwiNet Research Commercialisation Awards.The technology has just been named a finalist in the global SeaWeb Seafood Champions Awards.


Next steps

PSH is in the fourth year of a six year commercialisation programme and according to Dave Woods from PSH, “there is plenty of science still to be done.”

Specifically the focus will be on testing new configurations of the fishing technology – using it with different fish species (hoki in particular) and in a greater variety of conditions (deep water).

“PSH is set to be a game changer in the management of sustainable fisheries and growing the value of this important industry,” says Ben Dalton, Deputy Director-General Sector Partnerships & Programmes at MPI.   “PSH has massive potential economic and environmental benefits.”

Steve Tarrant, General Manager at Aotearoa Fisheries Limited says this is a system all kiwis can be proud of.  “This is a great example of New Zealand innovation at its best. We are very proud of what we’ve done so far and we hope as things progress more New Zealanders will get a sense of why we’re so excited about what we have here. This is a revolution in fishing and we are leading the way.”

Key Objective

To increase the value of New Zealand’s commercial fisheries through protection of fish stocks and quality of fish to market.

“This whole process has been an intimate collaboration between the New Zealand Seafood Industry who want to do things better.  This is New Zealand science in action and the industry partners deserve a pat on the back for bringing fishing into the 21st century.”
