Fisheries New Zealand is seeking feedback on proposed measures to mitigate risks to seabirds from data transmission
cables on fishing trawlers.
This feedback will play a significant part in the decision to allow the use of data transmission cables or not,” says
Fisheries New Zealand Director Fisheries Management, Emma Taylor.
“Data transmission cables attached to trawl nets provide information to fishers in real-time about what’s happening
under the water, so they can fish more efficiently and reduce their environmental footprint.”
The use of data transmission cables on trawl vessels was banned in 1992 because of risks posed to seabirds.
“Birds were often attracted to fish waste being continually discarded from vessels, and while attempting to feed, birds
would collide with deployed cables from the stern of vessels.
“In the three decades since the ban on these cables we have developed a better understanding about how to manage the
risks they pose to seabirds. This includes practices to manage fish waste which attracts seabirds, using devices like
tori lines to scare birds away, or bird bafflers that put a barrier between foraging birds and the vessel.”
The proposals to strengthen seabird protection from data transmission cables include:Changes to improve fish waste management practicesAdditional seabird scaring devices, such as bafflers or tori linesMinimising the portion of cables above the waterlineRestrictions on the areas and times of year data transmission cables can be used.
The consultation also seeks feedback on amendments to reporting and monitoring requirements should the use of data
transmission cables be allowed.
In 2022, Fisheries New Zealand consulted on lifting the ban on the use of data transmission cables.
Feedback from this consultation included that mitigation measures to protect seabirds should be reviewed before a
decision on allowing data transmission cables is made.
“If data cables can be introduced with appropriate protections against seabird bycatch in place, the data gathered has
the potential to support innovation and new technology to make fishing more efficient and reduce bycatch and harm to
protected species.
“The consultation is open now, and we encourage everyone with an interest in the use of data transmission cables and
seabird protection to have their say,” says Emma Taylor.
The consultation will run until 5pm on 9 August 2024.
