Rescue staff determined the plastic band cut the protected animal’s neck approximately two inches

A Steller sea lion is recovering after being disentangled from a piece of plastic that cut its neck approximately two inches.The male sea lion, weighing approximately 500 kilograms, was reported to the Vancouver Aquarium marine mammal rescue centre team after it was seen near Sooke with a plastic packing band wrapped tightly around its neck.Rescue staff, along with officers from Fisheries and Oceans Canada and a veterinarian from the SeaDoc Society, joined forces Monday at the Race Rocks Ecological Reserve to rescue the animal, which is protected in Canada as a species of special concern under the federal Species at Risk Act.

Since Race Rocks is made up of rough terrain and has strong currents, it took hours of jockeying positions for Martin Haulena, the head veterinarian at the aquarium, to dart and sedate the sea lion. Haulena did this from a distance using an air-powered dart containing immobilization agents.

The sea lion entered the water after being darted, which Lindsaye Akhurst, manager of the aquarium’s rescue centre said is a common response. Then, with the help of Race Rocks Eco-Guardians in the lighthouse acting as “eyes in the sky,” the team was able to spot the sea lion in some kelp and remove the plastic band that had cut into the animal’s neck approximately 2 inches.

Once the sedated sea lion was located in the water, the rescue team discovered that while the top of the plastic band was still slightly mobile, the bottom, or ventral portion, had cut into the animal’s neck approximately two inches. (SeaDoc Society photo)

A release from Ocean Wise said “the depth and severity of the wound indicated that the plastic had been there for some time.”

Team members tagged the sea lion’s flippers so if there are further reports about it rescuers will be able to identify the animal.

To date, rescue centre staff have rescued over 20 entangled sea lions.

B.C. surveys have documented hundreds more entangled sea lions in recent years, the release said, with some of the worst plastic offenders being ghost gear, including nets and ropes, and discarded trash such as the plastic packing bands used in packaging and shipping, which ensnare animals.

Not only are plastic items uncomfortable for marine mammals, Akhurst said, but the sea lions continue to grow while the plastic around them does not, which sometimes results in death.

Akhurst said Ocean Wise is working with the Fisheries and Oceans Canada on a stronger disentanglement program that specifically targets pinnipeds, a group that includes seals, sea lions, and walruses.

In late fall, a multi-day outing is planned that will focus on this problem on the west coast of Vancouver Island.

Sea Lion Rescued from Plastic Entanglement

Posted on by

A team comprised of the DFO and Vancouver Aquariums Marine Mammal Rescue (MMR) came out to Race Rocks on September 16th to help the entangled sea lions we’ve spotted over the last few weeks. Leaving from Pedder Bay at 0900, they arrived in two RHIBs at the reserve shortly after. After observing the struggling animals over the last while and communicating information with MMR, they were a welcomed sight.

Right away we spotted three possibly entangled sea lions from the lighthouse (unfortunately none of these three being the animals we photographed previously). We then landed the team of vet techs and veterinarian Marty at the jetty to assess the situation. It was decided that one of the sea lions resting by the water between the guest house and the helicopter pad was our best rescue candidate.

Marty and a videographer from Vancouver Aquarium approached over the helicopter pad from the direction of ‘Camera 5’. They got into position and a shot was taken, but the tranquilizer dart bounced and the sea lion fled into the water.

From the lighthouse we were able to follow its movements and keep the team apprised by radio. There was uncertainty about whether or not it received a partial dose of the tranquilizer as it floated in strange positions/patterns. Moving around Race Rocks to the water beside the solar panel/generator building, it hauled out again and another shot at it was lined up from one of the boats. The angle wasn’t quite right, and it again fled into the ocean and couldn’t be spotted. It was around 1400, and everyone took a break to have some food.

After this, everyone considered calling it off as it was getting late and we couldn’t locate the animal. At the last moment, with both boats ready to head back to Pedder Bay, it was spotted from the lighthouse (resting on the rock mound on the NW point of Great Race Rock)! Tranquilizing was attempted from water, but the dart bounced again and landed in the water and was recovered. Here’s a short video of that:


After that, it ended up too far from the water to try another shot by boat, so in a final effort the one boat landed Marty and the team again while the other stayed on the water to support. With no cover available between him and the animal, Marty had no choice but to crawl about one hundred feet in order to take the shot.

We were able to capture the following footage of the sea lion being darted, going into the water, and then after a tense 20 minutes during which a pod of transient orcas appeared in the reserve (who sometimes eat sea lions), it was found! The team proceeded to cradle the animal between their vessels and remove the plastic band. Then, they injected a reversal drug to reverse the tranquilizer before letting it go.

Everyone was relieved to have successfully helped an animal in need. We have suggested that future disentanglement efforts might have a better chance if extended to overnight stays in the guest house, and perhaps coordinated and executed in a more timely manner in relation to the animal sighting(s). This time we were unable to find the original animals that we had previously spotted, since it took quite a while to organize the rescue attempt. A big thank you to everyone who came to help this sea lion and teach us about their work!

Thanks to the rescue team, one more sea lion has a better chance of survival! (vet Marty holding the dart gun and dart used to tranquilize the sea lion)
