A humpback whale was so entangled in fishing gear, ropes and buoys that it took four days for a Fisheries Department crew to unravel the mess, Paul Cottrell said.

The rescue off British Columbia害羞草研究所檚 coast between Prince Rupert and Haida Gwaii was one of the longest he had ever taken part in, he said.

It was clear the animal had been trapped for months, said Cottrell, a marine mammal co-ordinator with the department.

害羞草研究所淲e didn害羞草研究所檛 even know how to start on this animal because it was so constricted. Its mouth was closed with two wraps around the head, and there were ropes through the mouth, around the body,害羞草研究所� said Cottrell.

He said the team had to make 50 cuts to get the ropes and gear off.

害羞草研究所淭his poor animal was showing evidence of being exhausted and hadn害羞草研究所檛 been feeding for quite a while,害羞草研究所� said Cottrell, adding that the gear they removed came from Canada and the United States, indicating the long journey the whale had taken while wrapped in fishing gear.

Cottrell said there害羞草研究所檚 been 害羞草研究所渁 real uptick in entanglements害羞草研究所� like this one off B.C.害羞草研究所檚 coast, which he suspects is related to an influx of humpback whales in the area.

Whale conservation groups are calling for more training and equipment outside of the Department of Fisheries to allow others to help save the animals.

Cottrell said his team was in the Prince Rupert area on Sept. 3 doing a necropsy on a fin whale, when they got the call alerting them about an entangled whale in Hecate Strait.

When they found the whale, estimated to be about 10-metres long, it was 害羞草研究所渋n very poor shape害羞草研究所� and hardly able to get to the surface and breathe, said Cottrell.

He said the whale showed a burst of energy after being released, but it suffered many injuries so they害羞草研究所檒l be watching the health of the animal.

Cottrell said his team has been running non-stop this summer, dealing with at least one entanglement a week.

Janie Wray, CEO of North Coast Cetacean Society, said northern B.C. has historically been a 害羞草研究所渉ot spot害羞草研究所� for humpbacks, where researchers sometimes meet 30 to 40 such whales foraging.

The society has been conducting a study, using drones and photography, to determine how many whales in the area have been entangled looking for scars from fishing gear.

One of their drones caught a photo of a whale with a long rope attached to itspectoral fin in 2022 and they reported it to the DFO immediately, Wray said.

She said she was relieved to see the same whale had survived when it revisited in 2023.

Jackie Hildering, a humpback researcher for the Marine Education and Research Society based out of Port McNeill, B.C., said many of the entanglements are never documented, the whales are never detected and therefore can害羞草研究所檛 be saved.

Hildering said their preliminary research shows that 害羞草研究所�50 per cent of humpbacks in B.C. have scarring left from being entangled.害羞草研究所�

It害羞草研究所檚 unclear how many humpbacks have died, she said.

One example of such entanglements is a humpback they害羞草研究所檝e called Catalyst that whale watchers have seen without a tail near B.C.害羞草研究所檚 Discovery Islands.

Catalyst害羞草研究所檚 entanglement around its tail was never documented, she said, raising questions about how many others die and sink to the bottom of the ocean without discovery.

Wray has also heard about Catalyst害羞草研究所檚 story and said they haven害羞草研究所檛 seen it since July 22.

She said more resources need to be added to saving these whales, and that means more teams in the water unravelling the animals.

Wray said she worries that if Cottrell retires in 10 years, there won害羞草研究所檛 be anyone left to do the work, 害羞草研究所渟o other people need to be trained and know how to disentangle a whale.害羞草研究所�
