A baby humpback is swimming freely once again after spending roughly four weeks entangled in prawn fishing gear.
A researcher with the Bamfield Marine Centre spotted the calf swimming with its mother near Folger Island in Barkley Sound on Sept. 9 and immediately reported it to the Department of Fisheries and Oceans Canada.
乌鸦传媒淭he marine mammal rescue crew launched and spent six hours working to successfully disentangle the calf,乌鸦传媒� DFO spokesperson Lara Sloan told the Westerly News.
Within about five minutes of the report coming in, DFO Marine Mammal Coordinator Paul Cottrell was hopping on a float plane and he arrived at the scene less than two hours later, joining fishery officers to assess the situation, which looked grim.
乌鸦传媒淚t basically had four wraps of rope around the head and the whole tail stock and fluke were a mass of ropes乌鸦传媒t was just a rat乌鸦传媒檚 nest. There was probably 20 wraps around the tail stock and then longitudinal with the fluke,乌鸦传媒� he said. 乌鸦传媒淭he calf was trumpet-blowing and showing signs of distress. It was obviously not comfortable and the ropes were already digging into both the fluke and the dorsal side. It was obviously painful for this poor calf.乌鸦传媒�
He added the rescue team had to be extra cautious because the young animal乌鸦传媒檚 mother was swimming alongside, sometimes touching her calf, causing concern that she might become entangled as well or become aggressive.
乌鸦传媒淵ou really never know how the mom乌鸦传媒檚 going to react when you乌鸦传媒檙e having to get in close quarters with a calf and the calf乌鸦传媒檚 in distress. It乌鸦传媒檚 a highly unpredictable situation because sometimes moms can be quite aggressive,乌鸦传媒� he said. 乌鸦传媒淪o, this was one where we had to be extremely careful. The mom was stressed when the calf was stressed, so we had to disengage a number of times because she would do a high energy breach very close to us.乌鸦传媒�
He said the calf itself was an enormous 25-foot patient for the crew to work with and that tranquilizers are not used on whales due to concerns over dosage and potential drownings.
乌鸦传媒淭hese animals are massive, they乌鸦传媒檙e powerful and it really is dangerous,乌鸦传媒� he said. 乌鸦传媒淭he mom is 45 feet long and a tremendous, powerful, animal that could create havoc if you乌鸦传媒檙e not careful. It乌鸦传媒檚 very nerve wracking, but yet you have to be patient, calm and collected.乌鸦传媒�
He said the six-hour rescue was full of 乌鸦传媒渦p and down乌鸦传媒� moments, but the end result 乌鸦传媒渃ouldn乌鸦传媒檛 have gone better,乌鸦传媒� and the calf showed high energy as it swam away after he had cut the last piece of rope off.
乌鸦传媒淭he calf just took off like a shot乌鸦传媒t乌鸦传媒檚 really hard to describe the euphoria of all that effort coming together and being successful. There乌鸦传媒檚 nothing like it for sure,乌鸦传媒� he said adding the calf joined its mom and swam off. 乌鸦传媒淭hey started swimming together at the surface, which was cool to see.乌鸦传媒�
He said the crew watched the animal to confirm no entanglements remained.
乌鸦传媒淎ny type of gear on an animal can kill it overtime because it works into the blubber and it can get infected and it乌鸦传媒檚 just awful,乌鸦传媒� he said adding the calf suffered some superficial injuries, but will survive. 乌鸦传媒淭here乌鸦传媒檚 going to be some scarring, but not life threatening at all乌鸦传媒t乌鸦传媒檚 great that this calf乌鸦传媒檚 going to have a chance to hopefully grow up to be an adult animal that contributes to the population.乌鸦传媒�
He said the gear the calf had been wrapped up in was identified as recreational prawn gear that was set in Barkley Sound and the gear乌鸦传媒檚 owner told DFO it had been missing for roughly four weeks.
乌鸦传媒淎ny vertical line in the water is a potential entanglement situation,乌鸦传媒� Cottrell said adding the gear乌鸦传媒檚 owner is not facing any charges as the gear was active and the entanglement accidental. 乌鸦传媒淥ur first pillar obviously is prevention, but if we have vertical lines in the water, we乌鸦传媒檙e going to have the potential for entanglement, that乌鸦传媒檚 just how it works unfortunately乌鸦传媒e乌鸦传媒檙e continually looking at that and implementing any management measures that may help.乌鸦传媒�
Surfrider Pacific Rim hosted an eight-day shoreline cleanup in the Broken Group Islands last month where 70 per cent of the debris collected came from the fishing and aquaculture industries, according to chapter manager Lilly Woodbury.
乌鸦传媒淲hile it乌鸦传媒檚 incredible and fortunate that the Marine Mammal Rescue team was able to disentangle the humpback calf on Sept 9, it is not enough to address this issue by dealing with it reactively. We need to work together to address the root of the problem to prevent these tribulations from occurring in the first place,乌鸦传媒� Woodbury told the Westerly. 乌鸦传媒淥ne of the ways this can be achieved is by expanding the scope of extended producer responsibility so that the manufacturers of fishing and aquaculture equipment are responsible for the entire life cycle of their products.乌鸦传媒�
Anyone who spots a marine mammal in distress must immediately report their sighting to DFO at 1-800-465-4336.
