August 5, 2021 — To cut down the chances of whale entanglement with fishing gear, researchers and developers are testing technology that would eliminate the need for the vertical lines that run between lobster traps on the seafloor and buoys bobbing on the surface.
Lobstermen are facing tighter restrictions to help with the recovery of the endangered North Atlantic right whales and so-called “ropeless” fishing is seen as one of the potential ways to ease that burden.
Traditionally, lobstermen have a buoy on the surface to mark their string of traps on the ocean floor, and they are connected by a vertical line. Ropeless fishing would ditch the persistent vertical line that sits in the water.
“We’re in a place where we’re still testing and doing research to see how much this can be part of the solution,” said Zack Klyver, the science director at Blue Planet Strategies. With his company, Klyver is working with gillnet fishermen and is looking for Maine lobstermen who might be interested in testing out the technology. “We’re actively looking for lobster fishermen that want to be pioneers, that want to see if this can be part of the solution.”
There are currently two main types of ropeless fishing. One is a trap-like cage that has a rope stowed inside. A lobsterman can trigger the release of the buoy, bringing the rope to the surface. The second type includes a lift bag in the trap. It blows up like a balloon on demand, bringing the trap along with it.
