Ny, nedslående rekord på Fiskeridirektoratet’s årlige opprenskningstokt

På Fiskeridirektoratets årlige opprenskningstokt ble det nok en gang satt rekord i antallet tapte og gjenstående fiskeredskaper som ble tatt opp og fjernet fra havbunnen. Dette på tross av av det ble lagt ned hele 20% mindre innsats enn i fjor. «Vi håper vår PingMe teknologi kan bli et viktig bidrag til bærekraftig fiske ved å hindre tilvekst av spøkelsesfiske», sier salgssjef Andreas Vie Murvold.

Fiskeridirektoratet gjennomfører årlige, havgående opprenskingstokt etter tapte og gjenstående fiskeredskaper, og melder at de nok en gang har satt rekord i antallet som er tatt opp og fjernet fra havbunnen. På årets tokt langs norskekysten og eggakanten ble det i perioden 7. august til 11. september fjernet hele 1637 fiskegarn på 50-1400 meters dyp. I 2023 ble en 20 år gammel rekord slått da de fjernet 1339 garn, men nå bare ett år senere er denne sørgelige rekorden slått med nesten 300 på tross av 20 % mindre opprenskingsinnsats enn i fjor. I tillegg til fiskegarnene ble det på årets tokt tatt opp og fjernet 25250 meter line, ulike typer juksesnører, 16500 meter tauverk, 78 teiner, store mengder vak og anker, samt 8400 meter med snurrevadtau. I tillegg ble det tatt opp over 5000 trålfiskekomponenter og ca. 300 kvadratmeter med notline. Fiskeridirektoratets Miljøseksjon er fornøyde med resultatet av årets tokt, men sier det er urovekkende at det aldri før har stått så mye tapte fiskeredskaper igjen i havet.

Selv om de årlige toktene med fjerning av tapte og etterlatte fiskeredskaper er et svært viktig bidrag for å redusere marin forsøpling og spøkelsesfiske, så har Fiskeridirektoratets handlingsplan mot marin forsøpling som visjon å redusere behovet for opprensking i fremtiden. Dette vil i stor grad være avhengig av gode, forebyggende tiltak for å hindre tilvekst av spøkelsesfiske-utstyr, og her må det største bidraget komme fra fiskerne selv. Ikke bare plikter de å melde tap av fiskeredskap, men også til å gjennomføre egne gjenfinningsforsøk. Slikt arbeid er svært utfordrende og ressurskrevende, fordi garn og fiskeredskap som man mister koblingen til fra overflaten er fullstendig underlagt bølger og havstrømmer. Det betyr at tapt bruk potensielt kan havne langt unna lokaliteten der man mistet det. I tillegg til en svært stor søkeradius, krever det å lete etter noe under vann på stort dyp, fjernstyrte farkoster og redskaper i million-klassen, ofte med spesialtrente piloter. Måten å løse dette problemet på, blir derfor å utvikle tekniske løsninger som setter fiskeren bedre i stand til å finne igjen tapt redskap, og samt å øke bruken av nedbrytbare løsninger i fiskeredskaper. 

«Vi ser at det utvikles stadig bedre og mer solide fiskegarn i nedbrytbare materialer, og at bruken av teiner med råtnetråd heldigvis er økende», sier salgssjef i Ocean Space Acoustics i Trondheim, Andreas Vie Murvold. «Men denne utviklingen tar tid, og det er absolutt ikke alle typer fiskeredskaper som kan produseres i nedbrytbare materialer. Ved å merke fiskeredskapen med en akustisk undervannsbøye fra oss, så kan du få den til å sende posisjonen sin opp til skipet dersom man skulle miste den. Vi har laget disse bøyene små og lette, og de kan enkelt hektes på garnet, nota eller trålposen med en karabinkrok. Bøyene tåler 1000 meters dyp, en rekkevidde på 2 kilometer, og en batteritid på opptil 2 år dersom den mistes. Under aktivt fiske kan bøya også logge temperaturdata som kan bidra til mer presist fiske slik at fiskerne fyller kvoten sin raskere. Dette sparer dem for drivstoff, som igjen er et pluss for miljøet.»

«Vi vet at vår teknologi kan bli et viktig bidrag til å finne igjen fiskeutstyr som har havnet på avveie, og på den måten redusere antallet dødsfeller for dyrene i havet», sier Murvold.

Global fishing industry applauds new ‘pinger’ system as a solution to the problem of locating lost gear

Since its inception three years ago ago by researchers at the Norwegian-based Ocean Space Acoustics (OSAC) the international fishing industry is eager to see the arrival of the ‘PingMe’ system – a scientific system that is set to bring an end to the financial and environmental impacts for fishermen who lose their pots, gill nets and even trawls. As well as giving critical information for the fishery about landing of the gear, temperature and currentinformation, the system provides more efficient fishing operations and season planning.

As well as the major financial loss for a skipper to lose his gear and catch, due to storms or being dragged away by another vessel, the environmental impacts of lost gear acting as ‘ghost fishing’ or seabed thrash has for many years been highlighted for the huge damage to fish stocks that it can cause.

And, as Sales and Marketing Director Petter Pettersen explains, that OSAC sprang out of SINTEF, Norway’s largest research institute: The idea was to find a workable and affordable solution to work towards achieving cleaner oceans but to also aid fishermen to avoid potential costly losses of fishing equipment and giving critical information.

From this high level marine scientific collaboration, and through a lengthy investment in research and development, the ‘PingMe’ was born – a smart tool for tagging gear and objects under water which, with new transponder technology or as a stand-alone (‘plug and play’) system, makes it easy to find and identify lost gear underwater.

The PingMe system can be used for better control during active fishing, by attaching transponders at regular intervals to the gear, better control of where the gear is currently located can make fishing more efficient and profitable. 

Following some delays in development and production due to the global pandemic, PingMe will initially be on the market as an affordable ‘standalone’ system (i.e. sensor and wheelhouse-based signal reader).

System

Already described by many as a ‘game changer’, PingMe consists of a small, user-friendly sensor device or ‘egg’ which is attached to the gear before shooting and, with a software module integrated in the boat’s chart plotter, this device not only acts as a locator and location monitoring system but provides vital data on current water temperature and direction/strength of tidal conditions.

PingMe software allows communication with the transponder to determine location and ID and, as an added bonus, the system’s service can, if chosen, also report location and ID to ‘the ‘cloud’ where the information is also stored and therefore important reporting data of gear that is lost, detected and retrieved gear can be saved.

This not only enables the fisherman to monitor the location of his gear but could, depending on how many users are using the information available, help avoid conflicts with other boats or fisheries who can use the system to ‘see’ where gears are working.

The transponder itself carries both active and passive versions as it lies dormant until pinged upon by a vessel with a PingMe transducer and reflects the sound waves originating from the transducer on the vessel. 

The reflected signal is encoded with a unique identity so that the sounder with PingMe software integrated can identity the transponder and calculate it’s position. This information can be encrypted if the information is to be transferred to the cloud. 

An added bonus of this new product is that the system’s sensor also relays information on water temperature at its location – knowledge that can greatly benefit fishermen when choosing the site for shooting their gear.

Market forces

While initial interest was expressed by many fishermen across Europe, it was when renowned Norwegian gear manufacturer and supplier Morenot, with 33 outlets worldwide, became the registered distributor for PingMe that new avenues began to open up.

Fred Helge Kaald, Marketing Manager for Morenot’s Russian operation says there is much anticipation for the PingMe system, particularly for their crab fisheries in the Bering Sea. And the Icelandic and Faroese crabbing fleets have also expressed an interest.

“Previously the biggest challenge to pot fisheries in colder waters has been that when the seas have iced up and trapped the fishing gear as, once the ice packs begin to move, they drag the fishing gear out of position and traditionally this has caused many problems for fishermen to relocate the gear – the PingMe tool will now do away with this problem,” Mr Kaald commented.

“We had originally hoped to launch this to the market last autumn at NorFish but Covid caused the postponement of all such events – so now we’re hopeful of launching in the coming months,” he said, adding that the benefits and potential of this tool are not limited to pot fisheries.

“There are many long line vessels working in the South Pacific fisheries such as Patagonian Toothfish and the fact that there are stringent criteria attached to this fishery due to environmental concerns, the availability of a device that can ensure the recovery of any lost gear has been welcomed by fisheries managers and participants alike,” he said.

‘A Game Changer’ – Innovative solution to end ‘lost gear’ problems for fishermen to save money and avoid environmental impact

The international fishing industry is set to welcome a new product on the market that will bring an end to both the financial and environmental impacts for fishermen who lose their pots, gill nets and even trawls.

As well as the major financial loss for a skipper to lose his gear, due to storms or being dragged away by another vessel, the environmental impacts of lost gear acting as ‘ghost fishing’ or seabed thrash has for many years been highlighted for the huge damage to fish stocks that it can cause.

As ever, the simplest ideas are always the best and when Norwegian-based Ocean Space Acoustics (OSAC) set about finding a solution, they collaborated with SINTEF, Norway’s largest research institute to work, not just towards achieving cleaner oceans but to also aid fishermen to avoid potential costly losses of fishing equipment.

This collaboration has resulted in the patented ‘PingMe’ – a smart tool for tagging gear and objects under water which, with new transponder technology either integrated with the boat’s sonar or as a stand-alone (‘plug and play’) system, makes it easy to find and identify lost gear underwater.

640,000 metric tons of fishing gear is lost on a global basis annually;

33% of all plastic litter in the ocean comes from the fishing industry;

20% of all fishing gear is lost in the ocean every.

Now reaching the latter stages of development, PingMe will initially be on the market as an affordable ‘standalone’ system (i.e. sensor and wheelhouse-based signal reader) but work is already underway to provide a system that will allow for simple integration of the signal reader into any vessel’s existing sounder. 

How does it work?

In layman terms, PingMe consists of a small, user-friendly sensor device or ‘egg’ which is attached to the gear before shooting and, with a software module integrated in the boat’s existing sounder system, or as a stand-alone system, this device acts as a locator and location monitoring system.

The PingMe software allows communication with the transponder to determine location and ID and, as an added bonus, the PingMe service also reports location and ID to the ‘Cloud’ where the information is also stored and data on lost, detected and retrieved gear is reported to the cloud, some of it automatically. 

This not only enables the fisherman to monitor the location of his gear but could, depending on how many users are using the information available, help avoid conflicts with other boats or fisheries who can use the system to ‘see’ where gears are working.

The transponder itself is passive and reflects the sound waves originating from the sonar – to a range of 1,000 metres. The reflected signal is encoded with a unique identity so that the sounder with PingMe software integrated can identity the transponder and calculate it’s position. This information can be encrypted if the information is to be transferred to the cloud. And, with PingMe’s scheduled online service, you can:

  • Register your own lost gear with associated ID, or
  • Report findings of other lost gears.

An added bonus of this new product is that the PingMe sensor also relays information on water temperature at its location – knowledge that can greatly benefit fishermen when choosing the site for shooting their gear.

PingMe can also be used for better control during active fishing, by attaching transponders at regular intervals to the gear, better control of where the gear is currently located can make fishing more efficient and profitable.

Feedback

Comments from fishermen in Norway suggest a very positive reaction to the PingMe system and, on the west coast of Ireland where harsh sea conditions are common, several lobster & crab pot fishermen are excited at the concept with one particular skipper commenting of the potential reduction in loss of gear as being of ‘huge benefit’.

“When my gear has been out for several days during stormy conditions, my only thought as I go to sea is ‘I wonder how many leaders of pots/traps will I have lost this time?” one fisherman said.

“Before even leaving my home, knowing that my gear is still where I left it, or at least if it has moved, that I will have the ability to go and find it would give me fantastic peace of mind,” he said, adding that a tool such as this which will reduce the major costs that fishermen face in replacing lost gear will be a ‘game changer’ for the industry.

The environmental angle

Fredrik Myhre, a marine biologist and senior advisor in WWF-Norway says ghost fishing through lost or abandoned fishing gear is one of the major killers for fish, mammals, seabirds and invertebrates in the ocean every year. 

“We need to improve our knowledge about the amount of fishing gear that is being lost at sea and at the same time to be more efficient in recovering what is being put into the sea in the first place,” he said, adding that a reporting system for lost fishing gear in combination with a demand for a technology to recover what is being lost will be important tools in order to reduce the horrible damage done by ghost gear worldwide. 

“We all depend on a healthy ocean – and both humans and marine animals are all paying a high price if the problems caused by lost fishing gear are not solved,” he said.
