October 7, 2020 — A group of state researchers in Boothbay Harbor are testing how much force it takes to snap hundreds of pieces of rope apart as they try to identify knot combinations and configurations of fishing line that will help protect whales from life-threatening entanglements.
Since early 2019, the small group of scientists at the Maine Department of Marine Resources have been testing a variety of different types of rope knotted together by putting them under strain with an old hydraulic tensile testing machine. They do their work in a garage bay on the department’s property on McKown Point Road. They have gone through a couple hundred different combinations of used and new rope tied together in various knots, testing each combination 10 times to determine their breaking points. They expect to try more than 900 different configurations in all.
The idea is to come up with a way Maine lobstermen can affordably satisfy federal laws that prohibit fishing activity from harming protected marine species such as North Atlantic right whales, of which only 400 or so remain. Maine lobstermen have been awaiting a new set of federal rules aimed at preventing whale entanglements that would force them to change the gear they use for the third time in slightly more than a decade.
The Department of Marine Resources researchers are hoping to find rope configurations that fishermen can put together from their existing gear, saving them the expense and trouble of replacing all their gear in order to continue harvesting lobster from the Gulf of Maine, which last year generated $485 million in statewide fishing revenue.
