Entangled Sea Lion gets rescued at Race Rocks
The rope had his right flipper ensnared, and it was caught on a rock leaving him tethered on the island
On December 13, 2009, Ecoguardian Ryan Murphy reported to DFO that a sea lion on Middle Island was entangled in ropes. (See Ryan’s comments below) The ropes were snagged so it could not leave the rock. A rescue was mounted by DFO and the Marine Mammal Rescue Centre of the Vancouver Aquarium on December 16. This was the first time a sea lion had been successfully released from such an entanglement.

Harlequin Ducks abundant
See Ryan Murphy’s harlequin images on Flickr
“’tis the season for Harlequin ducks here at Race Rocks. The particularly fine weather has emboldened the main group that spends most of its time on the east side of Great Race Island and they have been spending time around the jetty and on the west side of the island as well. Group size ranges from a single pair to more than twenty, with thirty or more individuals in the reserve the past couple of days.” Ryan Murphy-Ecoguardian Race Rocks.
“Harlequin Up/Down
Not sure when I’ll capture a moment like this again. Usually Harlequin ducks dive together or in close succession, but here one bird is popping to the surface as another one begins its dive.” Ryan Murphy
Ryan also took this photo today for a Northern sealion census: click several times for a very large image where individuals can be examined.
Slash returns.. early December
‘2009-12-02’, ‘Elephant Seal’, 1, ‘Our long-time viewers will be happy to know that Slash has returned to Great Race Island. His other preferred haul out in the reserve -Middle Rocks) is still densely packed with Steller sea lions. Slash is looking hefty, having put on weight during his time away from Race Rocks in preparation for the breeding season due to start soon!’, ‘Ryan’, ’11:31:30 ,
Acipenser transmontanus: white sturgeon
In this amazing picture, Ryan captured the spray of blood from the sturgeon as the northern sealion takes a bite. This is a first record we have for sturgeon in the Race Rocks Ecological Reserve. These images were taken by Ryan Murphy on the evening of March 2, 2009.

For confirmation of the identity of this fish, we contacted Lisa Spaven of DFO in Nanaimo and she helped us get in touch with a number of Canadian and American specialists in Sturgeon. There were some initial considerations that it may be a Green Sturgeoon but as the following conversation indicates, they have settled on the White Sturgeon:

Hi Troy
White or green?

From Troy Nelson: Director of Science
Fraser River Sturgeon Conservation Society
” I have looked at the pics of the sturgeon at Race Rocks and think it
may indeed be a white. Although darker/tinted coloration is present, I think this may be partially caused by the low sun and color of the sunset (see the pinks in the water behind the fish in the last pic).Most notable is the lack of a dark stripe on the bottom side of the sturgeon, anterior of the pectoral fins. There is one shot of the bottom of the sturgeon and this section looks devoid of any dark stripe.I have attached pics of a confrimed green sturgeon (from the Albion Test Fishery); note the dark stipe that ends in an “arrowhead” shape on underside of the upper body. I have copied Olaf Langness (WA DFW) who works with green sturgeon; he may be able to confirm if the Race Rocks sturgeon is a green (or white) in 10 seconds or less”.

From Chris Wood
“Thanks Troy, I was expecting it to be a green sturgeon in that location, but in one
picture, there seemed to be a (too?)close spacing of lateral scutes
between the pelvic and anal fin. We’ll see what Olaf says”…

Olaf Langness Fisheries Biologist (Washigton State Department of Fish and Wildlife)
“Thanks Troy for sending this to me.
I would say your assessment is correct. I think the Race Rock sturgeon was a white sturgeon. Besides your comments about the lack of a belly stripe, I also think the lateral scutes look small and plentiful, more that of white sturgeon than green sturgeon. As to the pink coloration, I agree that some of that may be the result of time of day when the photo was taken, but also would not be unusual for a sturgeon under stress to pink up on the lighter belly area, and even to darken slightly on top. Furthermore, there are way more white sturgeon identified in the surrounding waters of Race Rocks (off southern tip of Vancouver Island, in the Straits of Juan de Fuca) than green sturgeon, based on tagging studies and commercial or recreational landing reports. As you know, white sturgeon are being attacked this time of year, just below Bonneville Dam on the Columbia River. Many of these fish are mature adults, taken by large Steller (Northern) Sea Lions. The more prevalent California Sea Lions are smaller than the Stellers, so they tend to go after salmon and mostly leave the sturgeon alone. While we have been authorized to kill up to 85 California Sea Lions a year, the Steller Sea Lion is listed under our Endangered Species Act. So our marine mammal hazement program is focused on reducing predation on spring chinook salmon, and limited on what can be done to control the predation on sturgeon. This is of great concern to sturgeon managers in Washington and Oregon, especially due to the sea lions targeting of the spawning broodstock .”

Mammal Census
Jan 9, 2004: Over 250 Northern Sea Lions ( many juveniles) on middle rock only today- One large male elephant seal there also and one on Great Race – ( On the lawn near helipad- check on the robotic camera ) Several bald eagles on the rocks.
Sealions that seemed to be ‘fishing’ together,
Good Evening
TEMPERATURE: Max. 9.5 ºC »» Min. 3.9 ºC »» Reset 6.8 ºC
MARINE LIFE: Watched a group of 5 or 6 Northern Sealions that seemed to be ‘fishing’ together, since most of the action took place under the water it is only conjecture but 4 good sized fish were brought to the surface within seconds. Other marine animals are known to work together to corral fish so it is not too surprising that sealions might as well. There are still fish balls but are small and short lived with fewer birds.
HUMAN INTERACTION: There were 14 Ecotour boats,1 research boat( the Drifter) 3 sail boats, 1 Dive Charter and 2 pleasurecraft in the MPA today.

LGL does contract for DND on Blasting
Good Evening
TEMPERATURE: Max. 7.9 ºC »» Min. 5.0 ºC »» Reset 6.7 ºC »» Rain 0.8 mm
MARINE LIFE: The California Sea Lion with the injured hind flippers is still hauled out on the dock and keeps to it’s self. The poor animal is most likely in pain- looks quite thin, probably not able to manouever too well to catch it’s food.
HUMAN INTERACTION: 6 Ecotour boats, LGL observers boat. The Second Nature made two trips, one about noon With Garry and his class then again with Garry, Scott and Don to work on Camera # 2 system.
MARINE LIFE: (Reported by Garry Fletcher) I had the opportunity to be at Race Rocks twice today. On first arriving at 11:45 AM it was obvious that the DND had been conducting their explosions on Bentick island. We have gotten used to the sealions building up their numbers over the past few weeks. The main island to the East of the House , and the whole northeast front have been covered with animals throughout the daytime. The major concentration however has been on the middle island, which if you have been checking on camera 1 these days has been covered with a mass of bodies. By 11:45 today most of these areas were bare.. only a few brave individuals had crawled back up on the rocks we will see tomorrow how many have returned, but if it follows the patterns of other years, their numbers will start to taper off if the harassment continues. This year the DND has decided to check out our allegations of harassment of these endangered species — yes that is the category the Northern Sea Lions now occupy in Canada. A contract has been let to the consultants of LGL to survey the effect of disturbances, so they have had observers in the tower on the two occasions of blasting this fall. Today the result was obvious. The irony does not escape one that this is an ecological reserve, an MPA and even that does not protect endangered species in Canada.. For a video of the effect of a blast on the behaviours of the birds and mammals at Race Rocks, go to one I recorded on October 7 – its in the marine mammals archive at: http://www.racerocks.com/racerock/archives/viddndblast.htm

Injured Northern Sealion
Good Evening
TEMPERATURE: Max. 12.7 ºC »» Min. 7.7 ºC »» Reset 9.9 ºC »» Rain 0.4 mm
MARINE LIFE: There is a Northern Sea Lion on the middle rock with a large raw looking wound on it’s back. Have not seen the goose that appeared to have a damaged wing, must have flown back to the mainland. Only a 3 degree drop in the temperature but the air is damp and feels much more like fall. The Sea lions are very quiet today, not as many birds today either. Did hear at least 2 Black Oyster Catchers vocalizing several times around 2 a.m. last night, I wonder what they are up to in the dark.
HUMAN INTERACTION:There were 8 Ecotour boats and 5 pleasurecraft through today.

MARINE LIFE: California Sea Lion hauled out in group of about 80 ( 11 Northern ) has a brand # 823 and a yellow front flipper tag # 925.The Sea Lions are still being disturbed by boats approaching too close especially along the east tip of North Rocks and along the north shore of Gr. Race. They are very used to us coming and going along the dock, in fact there are 3 that particularly like the last step on the dock as a haul out spot and often stay put as we come alongside in the boat.Unfortuately the mess they leave behind does not always wash away with the high tide! Four Black Oyster Catchers spent several hours along the east ridge but were very quiet and did not see any of them feeding, mostly resting on one foot with bills tucked under their wings.
HUMAN INTERACTION: There were 11 pleasurecraft, 2 dive boats ( 1 charter, 1 milatary dive club ) also the LGL crew via zodiac – preparing for monitoring the DND blasting exercises tomorrow.
