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.

Over the past two decades, Vancouver Aquarium head veterinarian Martin Haulena has helped develop a precise drug combination to ensure that sea lions can be safely freed, without harming itself or others. (SeaDoc Society photo)

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)

Hustle and Bustle / Pleasure Craft Violation / Census

Posted on by

Weather: 

  • Sky overcast, hazy, steady rain this afternoon
  • Visibility 15 miles this morning, < 2 miles this afternoon
  • Wind 0-10 knots NE
  • Water calm

Boats/Visitors: 

    • A whole boat load of visitors this morning! VP of Pearson College Tyrone, Alum in residence Norbert and friends to advise on our solar panel system, a desalinator consultant (in preparation for the new desalinator!), and an insurance appraiser.
    • Fewer whale watching boats this week, but we have been concerned about the frequent use of flash photography and its possible effects on the wildlife.
    • Greg also made another trip to bring us some water this afternoon.
    • Yesterday we watched a pleasure craft approach the sea lions near our jetty and throw some kind of food at them (some of it hit the sea lions). We were able to capture them scaring the animals, who stampeded into the water. They hovered to take photos and unfortunately pose with their open alcohol. Even more unfortunate, the bait that we saw being thrown at the sea lions previously and perhaps this time as well is not suitable for consumption, as many times it has been treated with formaldehyde.

Ecological: 

  • Many sea lions now, and unfortunately a few that are injured. Aside from the two that we have mentioned previously, we have been finding more fishing hooks scattered around and a sea lion appearing to have a nasty wound possibly caused by an embedded fishing hook.
  • This afternoon we also noticed a sea lion with a propeller inflicted gash on his head. He seemed to be dazed or perhaps concussed due to the injury. Normally the sea lions are skittish and make a ruckus if we get too close, but this one didn’t react to our presence and seemed notably lethargic. We were concerned that he might fall victim to the injury, but approximately an hour later he seemed more alert, reacted to our presence, and seemed to be doing okay.
  • We reported the tagged sea lion to the researchers in California and were excited to hear that they have some information about him and his early life. We hope to be able to share more soon! This little guy has already swum almost 1500 km from his birth place, Ana Nuevo CA.
  • Yesterday there was quite a bit of smoke caused by controlled burning taking place on the nearby DND land. They burned 20 hectares of Gary Oak habitat to protect the species (from invading conifers) and and prevent spread of invasive plants.

Census:

  • 350 sea lions
  • 50 harbour seals
  • 1 elephant seal
  • 40 cormorants
  • 60 adult gulls, and some chicks (they are too hard to see from the lighthouse)
  • 4 geese
  • 20 turnstones

 

More Sea Lion Injuries Due to Fishing

Posted on by

Weather: 

  • Sky partly cloudy, some periods of fog
  • Visibility 1-15 miles intermittently
  • Wind 20-30 knots W – NW
  • Water rough, whitecaps, swells around 1m

Boats/Visitors: 

  • No visitors today, but on Sunday Corey drove us back to Race Rocks with some more water as we were having troubles getting our boat to start.
  • There have not been many whale watching boats but when they are here they often get quite close to the sea lions (within 10m). We can tell when there is a boat present in the reserve by the increase in “barking” and distressed sounds that the sea lions make.

Ecological: 

  • Over the weekend a sea lion was spotted with some fishing line wrapped around its neck. We believe that it could be the same one spotted last year. As it grows it will likely die due to slow suffocation caused by the line. Unfortunately it’s virtually impossible to have someone come to tranquilize and remove the line as the sea lions move on before they can get here. However, if we see it again we will report the injury.
  • Today we found a large fishing hook which must have come loose off of a sea lion. We’ve previously observed sea lions trying to remove fishing hooks from their skin by rubbing against the jetty.
  • There are quite a few sea lions all over the island now. We have been delaying our water sample that we normally take from the jetty to avoid having to chase them off, since when they are startled they climb over each other or rush off of the side of the jetty where the water isn’t very deep. The few that have come near the house don’t seem to be moving around much, just resting and getting away from the crowds.
  • With the return of the sea lions we’ve been getting bitten by little black fleas that we also saw in late spring. They were not a problem while the sea lions were not here, so we’re wondering if the two are connected.
  • Many of the young seagulls have left or are flying very well. A few of the latest hatched are still here, but the mothers are starting to leave them to fend for themselves.
  • We have been spotting the odd young elephant seal hauling out for a few hours before continuing on.
  • We’ve been noticing eagle feathers and dead adult seagulls around the island. Oddly, we haven’t seen the eagles hunting.

Maintenance: 

  • We’ve been needing to do daily fence repairs on the electric fence at the back of the island as the sea lions have been trampling it and breaking the wire and insulators that hold the wire on the posts. Hopefully with some persistence on our part they will learn to leave it alone.
  • Today we also set up the electric fence that runs between our house and the jetty/north island to prevent them from coming up around the infrastructure. They are stinky and destructive if you let them get too close!
  • We are still picking up sharp bits of tin and shingles/tar paper/ misc. litter from around the island. Some of it is from the roofs being redone recently, but a lot of it is older and becoming exposed now that the grasses are dormant for the summer.  Today we filled two buckets in an hour or two of scavenging.

A Foggy Weekend

Posted on by

Weather: 

  • Sky partly cloudy, some thick fog banks passing over us
  • Visibility 5-15 miles, intermittent fog
  • Wind 0-5 knots W
  • Water calm

Boats/Visitors: 

  • Yesterday we had a great team of volunteers come to help remove the rest of the shingles and accumulated rubbish from around the island. We still have some more to go but it’s looking great!
  • Greg showed us how to set up the electric fencing to keep the sea lions off some of the island. Yesterday we set up one at the back of the island and will need to set up the fence near the jetty soon.
  • Today Corey and his family will pop in for a visit
  •  Our friend is going home this afternoon

Ecological: 

  • We spotted the seagull chick that had been attacked (and lost an eye) yesterday and it’s doing well. It is missing an eye now but is learning to fly alongside the others.
  • We saw two orcas pass just outside of the reserve on Thursday
  • The sea lions have started to come further onto the island, and there are more and more each day

Update on Tagged Elephant Seal Cow

Posted on by

T 562 pink

Recently I sent this email to the folks who are in charge of the tagged elephant seal program in the US .” This year we have had three pups born The tag (on this website) for pups born here over the last few years is https://www.racerocks.ca/tag/pup/ This year the first pup belonging to one of your tagged females, pink tag T562 is doing very well. One other one is ok but the last born one has been mauled by one of the mothers and has died. It would be interesting for us to know when this tagged mother was born so that we know her age and origin

***********************************************************************************************

NOTE : The following link is connected to all the posts on this log relating to tagged elphant seals we have recorded at Race Rocks Ecological Reserve over the past 19 years

https://www.racerocks.ca/tag/tagged/

Today we received this information from Garrett Duncan, Farallon Program Biologist at Point Blue Conservation Science. www.pointblue.org  :

The cow you re-sighted with a Pink tag T562 was born on the SE Farallon Island during the 2010-2011 breeding season and hasn’t been seen since. It’s mother’s name in our database was Peggy and she was likely born in the 1998-1999 breeding season in a colony further to the south, Piedras Blancas. She frequented the island every year between 1999 and 2011.
