August 11, 2022 — In their latest effort to protect endangered right whales, federal regulators have released a plan to increase the use of on-demand – or ropeless – fishing gear, an initiative that includes expanded testing of the new technology.
In an effort to address the two main causes of human-induced whale mortality – vessel strikes and entanglement in fishing gear – the National Oceanic and Atmospheric Administration recently released rules to reduce ship speeds and its “Ropeless Roadmap” to prepare for widespread adoption of ropeless fishing.
The vertical lines that connect strings of traps on the ocean floor to buoys on the surface can get caught on a whale’s fins or in its mouth as it swims, leading to death in some cases. There are fewer than 350 North Atlantic right whales, according to NOAA.
On-demand fishing gear would eliminate the need for the vertical lines in the water until the lobster trap, pot or gillnet is being hauled. Different technologies are under development now. Some include floatation devices that are triggered by an acoustic signal to return the gear or rope end to the surface when the fishing boat returns to collect it. Others use timers to release the rope and buoy to the surface, reducing the amount of time the rope is in the water column. And in a lower-tech option available in some cases, the traps or other gear can simply be removed by a grappling hook. The location of the gear can be communicated to boats above by acoustic signal.
