Tiaki – New Zealand launches a new method for harvesting premium seafood

Fishing the Tiaki way replaces traditional trawl nets with modular harvesting systems, a more sustainable way of fishing producing higher quality seafood.

When fishing in-shore species; Tiaki caught fish are brought on board alive, swimming in the water and in pristine condition. There is also the potential for an undersized or unintended catch to be returned to the sea with a much higher survivability rate.

When used to harvest deep water species such as Hoki, the new technology is reducing the damage to the fish, increasing the quality and adding significant value to the catch.

Tiaki is the latest stage in the six-year Primary Growth Partnership between the Ministry for Primary Industries and three of our commercial fishing companies - Sanford, Sealord and Aotearoa Fisheries – representing a combined investment of 48 million dollars. The partnership was launched in 2012.

Ministry for Primary Industries Director-General Martyn Dunne says even though it is still being trialled Tiaki has already demonstrated huge potential.

“A lot of the industry players around the world are looking in at New Zealand and thinking this is wonderful.”

“What it is going to show to consumers in New Zealand and around the world is that we value our provenance story, we value the sustainability of our fishing stocks, and we have a story that we can tell the world of how these fish have been caught sustainably. The programme has around two years left to run, but we are seeing truly exciting progress.”

Programme manager for Precision Seafood Harvesting Dave Woods says there is increasing demand from consumers to be more connected to where their food comes from and the methods used to harvest it meant the commercial fishing industry needed to transform.

“This is a changing world, people are demanding to know where their seafood comes from and they are demanding that we care for the stocks of fisheries that we fish. We have to rise to that challenge and we have to use every available technology to do that.”

And that technology is not only working below the sea, Tiaki caught fish will come with its own traceability app meaning consumers can quickly find out more about where and how their fish was caught using their smartphone.

It has taken 10 years of New Zealand research and four years of trialling the technology on board boats to get to this point.

Precision Seafood Harvesting technology was developed by Plant & Food research, a crown research institute based in Nelson.

The team of 14 scientists, led by Alistair Jerrett, set themselves high goals in developing new ways to fish with the overall objective for PSH of improved survivability rates for unintended catch.

“The best case scenario is always release at depth, that juveniles are not even brought on board. But equally important is increasing survivability rates for those that are.”

Senior scientist Suzy Black says the commercialisation project still retains a strong element of innovation and development work.

“The great thing about this work is that we are learning more and more about the behaviour of fish – and it is very different from species to species.”

“With cameras on the nets we can see what is going on below the surface, and compare the number of juvenile fish coming on board the vessel with the number of fish actually interacting with the net.”

“Alongside this we are working on the handling systems on board, changes to vessels and the regulations around how we fish.”

Market potential

Tiaki caught fish is tipped to be a big earner and marks a move by the three companies involved towards value over volume.

CEO of Sealord Steve Yung says capitalising on the demand domestically and worldwide for premium seafood is important for industry.

“The bulk of NZ’s fish is exported so export is the lifeblood of industry here.”

“The quality of the Tiaki caught fish is really going to give us the opportunity to set New Zealand apart from the rest of the world and give us a competitive advantage, particularly in the markets of Asia.”

“In terms of the resource we have in New Zealand, it’s limited. The Tiaki brand and technology will allow us to take advantage of the fact that it is a limited resource that we care for, that we catch sustainably, and that we can add value to.”

The Government set a target of doubling the value of New Zealand’s primary industry sector exports to 64 billion dollars by 2025, and it is hoped Tiaki caught fish will make a significant contribution towards that.

Precision Seafood Harvesting on Ocean Bounty

Screen-Shot-2017-07-07-at-4.14.45-PM

Three’s Ocean Bounty series has featured Precision Seafood Harvesting on two of their episodes. This episode of the programme follows Moana fisherman Sam Hayes and his crew on the Jay Debra as they use Precision Seafood Harvesting to produce high quality, fresh fish. This is a great watch to see how the PSH technology works and the changes it’s driving for the New Zealand seafood industry.

Precision Seafood Harvesting in New Zealand Series

Screen-Shot-2017-07-12-at-11.24.44-AM

Seafood New Zealand have put out a mini documentary series on New Zealand’s seafood industry. Precision Seafood Harvesting features in the episode on innovation. It’s a first look at the new onboard handling systems we’re using to improve the quality of our fish and increase the survivability of fish we return to the ocean.

Watch the episode featuring our technology here. 

The teams of skippers, fishers, scientists and inventors behind the new Precision Seafood Harvesting fishing technology say they’re very pleased PSH has been approved for commercial use in the deep water Hoki, Hake and Ling fisheries.

The Precision Seafood Harvesting System (PSH) technology is the first non-mesh commercial fishing innovation to be approved for use in New Zealand following changes to the fishing regulations last year. The technology has been developed to help fishing vessels add-value to deep-water fish species that are landed on-board in better condition. 

PSH Programme Manager, Dave Woods, says six years of trials with these deep-water species, show that when using the PSH technology the fish are in much better condition and quality when they’re landed.   This is possible as the fish are held in conditions of very low velocity water flow and this is the biggest difference compared to normal mesh-based trawl designs. “Importantly fish that do go through the escapement holes underwater have a better chance of survival than if they go out through traditional trawl mesh.”

Woods, who has been with the programme since it started in 2012, says the new way of fishing will mean New Zealand can sell a higher proportion of the highest-grade fish.

“We can get a higher value because the fish aren’t damaged.  For hoki, that means more product at the higher end of the quality cascade, such as skinless fillets or whole chilled hoki, and less volumes of the lower end products like B-grade fillet blocks, mince or fishmeal.” 

Precision Seafood Harvesting is a $44 million, 7-year Primary Growth Partnership (PGP) between MPI and three fishing companies, Moana New Zealand, Sealord Group and Sanford Limited to develop new fishing technology based on science from Plant & Food Research. The investment is split between MPI and the three fishing companies.

“This is the first innovation of its kind in 100 years of commercial fishing that has been approved for commercial use.  It has taken six years to get to the point where we could even submit this alternative design for approval because the historical regulations were about mesh nets.” 

“We hope this is a step change for innovation in the way we fish.  To do this we have had to test and prove every aspect of the new designs because they are so new and different and this has never been done before.”

Wood says the approval is just a first step for PSH, which is working to get commercial approval for other species. It also gives confidence to the support teams around the project that they can build on it and grow the support industry.

“PSH isn’t just creating a new way to fish, it’s creating whole new industry opportunities around this innovation like manufacturing and supporting the new fishing gear and new vessel designs.”

“This approval also starts to build a foundation for regional development in terms of manufacturing for new prototypes of this technology.  Until we had commercial approval it has been difficult to justify the capital investments required to scale-up the manufacturing capabilities.  This was due to the uncertainties of an experimental technology that didn’t have regulatory approval – now we’ve got the first approval it will open up commercial opportunities for manufacturers.”

“The next step will be the innovation that we expect from our skippers and fishermen over the next 10 years through increasing usage of this new technology. The learning curve and innovation curve from now will be exciting.”

“While the team is focused on completing the work we need to get approval for other species, including inshore species like snapper.  We’re also working on the exit planning needed for 2019 when the PGP programme ends.  

“The world is watching this technology.  There’s been a huge amount of amazing kiwi IP and expertise built up through this programme and we need to make sure we’re able to utilize all of it when this new technology is fully commercialised. ENDS

Transforming Bulk Seafood Harvesting by Producing the Most Authentic Wild Fish

The Primary Growth Partnership ended in March 2019 having achieved much. Key concepts and 6 project workstream results are summarised and further papers will cover technical and policy/regulatory developments. The gear will be commercially available worldwide in 2022 and be underpinned by this independently peer reviewed information.

Key Concepts

  • Well-managed fisheries increase value through improving productivity, quality and efficiency rather than increasing volume. From being a frozen, commodity fishery, the New Zealand Hoki fishery has learnt how to preserve inherent, natural qualities.
  • Trawling is economically efficient bulk fish harvesting and has relied upon collecting exhausted fish in the cod-end. Fish are physically damaged and highly exercised i.e. every uncontrolled interaction is a potential deficit.
  • New Zealand fish physiology scientists collaborated with leading seafood companies and the government in the Precision Seafood Harvesting (PSH) Primary Growth Partnership (PGP) to develop technologies to harvest key commercial fish species in minimally damaged, minimally fatigued condition to enable the quality potential to be realised for rested harvested fish.
  • They envisaged and developed a modular harvest system (MHS) to match the internal waterflow velocity with key species’ swimming speed. MHS fish could surface alive, neither injured nor stressed and smaller fish and unwanted species, including megafauna, could escape or be released and survive. Being rested, the muscle/raw protein material quality is significantly improved which dramatically increases higher value product options.
  • This MHS is in commercial operation in New Zealand deepwater fisheries and under trial in inshore fisheries.
  • It could significantly transform bulk harvest fisheries worldwide.
