Agonomalus mozinoi: kelp poacher–The Race Rocks taxonomy

This is a very secretive fish that was not identified until the 1970’s, probably due to its elusive and often nocturnal habits. Ryan spotted this one near the end of a dive as it made a quick getaway, resulting in the blurry images.Note the jellyfish Mitrocoma cellulari on the left side.

Scorpaenichthyes marmoratus : Cabezon –The Race Rocks Taxonomy

 

Cabezon:(literally big head in Spanish ) is a benthic fish that lives among the kelp holdfasts and rocky areas, usually very close to the bottom. It is often so confident of its camouflage that it will not move when approached by divers. Note the multi colored eye. These fish will lunge at almost anything that moves on the bottom. Dissections of their stomachs reveal amphipods and small crabs, pieces of kelp (and even rocks they have grabbed when foraging for other invertebrates.)

Cabezon are normally benthic or bottom-dwellers, living among rocks and seaweeds in tide pools. Sometimes they live just below the water’s surface among the marine plants. Their coloration allows them to remain well camouflaged. Their habitat is most likely rocky, sandy and muddy bottoms, living in areas with a depth range of 0 to 200 meters. Moreover, young cabezon feed on small crustaceans like amphipods, shrimp, and crabs. The adults feed on crustaceans, marine worms and mollusks, including clams and abalone. They can swallow a whole abalone and later regurgitate the indigestible shell; therefore, their tropic level is that of a secondary carnivore. In addition, the limiting factors that will affect the development and growth of this population in a certain habitat will be the presence of enough light, temperature and the availability of food and living space

Their maximum length and weight are 99.0 centimeters and 14.0 Kilograms respectively. This organism can be seen in the Eastern Pacific, which covers the areas from Southeastern Alaska to Punta Abrejos, in Central Baja California, Mexico. Race Rocks is located in the centre of this range. In this map we can see the range of this fish.

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.

See Ryan’s Flickr site:

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”…

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 .”

Dogfish are not usually seen by divers but they occur in the waters around Race Rocks. They are often caught by fishermen and released . The captured one above is the first one recorded for the reserve.gullshark1

Sebastes melanops: Black Rockfish– The Race Rocks Taxonomy

Physical description

We frequently see schools of these rockfish hanging about when we are diivng at Race Rocks. As you can see in the video, they remain at a distance as the diver swims into the group. They are a thin bass-shaped fish with few head spines. It is black, blue and black, spotted with grey or blue and grey, with black spots on the backs and dorsal fins.


Global distribution:
It lives in the ocean from the area of Amchitka Island (Auletian Islands) southeast to S. Miguel island and S. Barbara (southern California). We can find it from central California to south eastern Alaska.
Habitat:
It usually lives in mid-water or surface, but it has been captured down to 1.200 feet.
Feeding:
Young fish eat plankton and larvae, old eat mainly fish and zooplankton.

Predators:
Their predators are ling cods, sea lions and pigeon guillemots.
Reproduction:
Females are viviparous. From September to November they store the sperm before fertilizing the eggs. They let go young from January to May, peaking in February off California. One interesting fact: They live in groups of thousand of elements. They are good swimmers, in fact they can move hundred of miles.

Oligocottus maculosus: Tidepool Sculpin–The Race Rocks taxonomy

rmsculpinn

Sculpin image by Ryan Murphy

Sculpin have ability to blend in with their surroundings which is useful in escaping from enemies and in capturing their prey by ambush. The body is elongate, its depth about 10cm. Head somewhat depressed, its length about 6cm. The snout is blunt in profile and It is moderate in size, the upper jaw extending to mid-pupil.
The species is very abundant in tide pools around rocky the rocky shores of Race Rocks. Tide pool sculpins show a definite tendency to return to their home pool if moved. These are very abundant in the tidepools on the north east corner of Great Race Rock. A piece of edible tissue dropped into a pool usually causes a feeding frenzy.
