IT, The ornamented blenny was first taken in British Columbia waters April 20, 1912, at Snake island near Departure bay. This was a small male specimen and it is now in the fish collection of the Pacific Biological Station. Four other individuals were obtained in May, 1934, south of \anaimo on the reef at False narrows. An examination of the gill filaments of this species disclosed the fact that their structure was similar to that of Chirolophis polyactocephalus, therefore the genus should be known as Chirolophis instead of Bryostemma. This is a small species found tinder rocks in the intertidal zone. It is strikingly marked and one of the handsomest of the blennies. Range northern California to strait of Georgia. Decorated blenny Chirolophis polyactocephalus (Pallas) 1811 Body elongate, moderately slender, compressed. Head short, blunt; mouth terminal, small, oblique; lips thick; teeth on jaws, small; gill membranes united, free from isthmus; gill filaments thin, plate-like, bearing on each side series of numerous leaflets.

Scales: c}rloid, small, embedded. Cirri: numerous, high, plumose, fleshv, covering top of head, extend- ing backward to first 4 to 8 spines of dorsal fin. Colour: pale brown, with white to cream markings; light areas on upper half of body, irregular to almost pent- agonal with dark centres; white bars in series on lower half of bodv; dark band extending downward from eye to lower margin of cheek, thence backward, prominent; black bars on dorsal, anal and caudal fins prominent, on pectoral fins, faint; on pelvic fins, dusky white. Length to 16% inches. Distinguished by the numerous plumose cirri on the top of the head and ex- tending onto the first 4 to 8 spines of the dorsal fin, the anal fin with 1 spine and 44 to (il rays and the general coloration. The decorated blenny was first taken in British Columbia waters in No- vember, 1890, at Alert bay, by 'Mr. Spencer. This was a specimen 141 ; inches in 178 length, deposited in the Provincial Museum at Victoria and recorded in 1891 by Ashdown Green as Chirolophus polyactocephalus. In 1903 D. S. Jordan and J. O. Snyder described Bryostemma decoratum and expressed the opinion that all specimens previously referred to as Chirolophus or Bryostemma polyactocephalus, taken on the northeastern shores of the Pacific ocean, should be considered as Bryostemma decoratum. In 1942, P. J. Schmidt pointed out that the peculiar structure of the gill filaments of this species were of the nature of those described by Swainson for the genus Chirolophis, hence the scientific name should be Chirolophis polyactocephalus (Pallas). Individuals have also been secured in the following localities: Juan de Fuca strait, English bay, Burrard inlet, Stuart island, Alert bay and Prince Rupert harbour. The species has been secured at depths ranging from 10 to 50 fathoms. Range Puget sound to northwestern Alaska. Saddled blenny Pholis ornatus (Girard) 1854 Body elongate, moderately slender, compressed. Head small, compressed ; mouth terminal, small, oblique; teeth small, conical; gill membranes broadly united, free from isthmus.

Pholis (»luaus (Girard) 1854 pectoral small, length about half that of head ; caudal, rounded. Lateral line; absent. Scales: cycloid, very small. Colour: olive green to brown on dorsal surface; yellow, orange or red on ventral surface; dark bar across head behind eyes; dark bar downward from eye; dusky bars in series across sides of body; black markings in series along base of dorsal fin "V" to "U"-shaped, enclosing dark green or brown areas darker than body colour; orange sometimes on pectoral, anal and caudal fins; light green with series of white bars on anal fin in some specimens. Length to 12 inches. Distinguished by the series of "V" to "U"-shaped black markings along the base of the dorsal fin and the presence of the minute pelvic fins thoracic in position each with 1 spine and 1 ray. The saddled blenny was first recorded from British Columbia waters in 1861 from Vancouver island by A. Günther as Centronotus nebulosus on the basis of 3 specimens collected by Lieut.-Col. Hawkins of H.M.S. Plumper. The 179 species was listed in 1898 by J. Fannin as Muraenoides ornatus on the basis of an inclividual in the Provincial ^^Iusetn. (Man}^ of the records of Pholis ornatus may be confused with the followinl; species, Pholis laetus, because of the fact that over a considerable period of years the two species were considered identical and were recorded as P. ornatus.) The first definite locality record from these waters is that of a single individual taken in 1885 in Houston Stewart channel by Dr. G. M. Dawson and recorded in 1920 by B. A. Bean and A. C. Weed. Specimens have been taken at Fort Rupert, Union bay, Departure bay, Burrard inlet and Victoria. The saddled blennv occurs frequently near the mouths of streams on muddy bottoms at depths between 10 and 20 fathoms although it is found occa- sionally in the intertidal zone. It feeds upon small crustaceans and molluscs. Range northern California to southeastern Alaska. Bracketed blenny Pholis laetus (Uope) 1873 Body elongate, moderatelv slender, compressed. Head small, compressed; mouth terminal, s,nall, oblique; teeth small, conical; gill membranes united, free front isthmus.

Length to 10 inches. Distinguished by the series of bracket-shaped black markings along the base of the dorsal fin and the presence of the minute pelvic fins thoracic in position each with 1 spine and I ray. The bracketed blenny was first taken in British Columbia waters in 1903 by the Albatross as follows: June 23, at ('mon bay; June 2-5, at Fort Rupert; July, at X7etlakatla near Port Simpson. These specimens were recorded in 1907 by B. XV. Evermann and E. L. Goldsborough as Pholtis ornatus, although figuring Pholis laetus. Re-examination of the collections from these localities by Dr. L. P. Schultz revealed the presence of P. laetus as indicated above, and P. ornatus 180 at Union bav and Fort Rupert. The bracketed blennv is common along the coast in shallow water, being found frequently in the intertidal zone, around seaweeds and rocks, in tide-pools and occasionallv down to 30 or 40 fathoms. It has been taken in Burrard inlet, Departure bay, Aootlca island, Atassett inlct and Prince Rupert. harbour and apparently is more conmion northward.

Copyright © 2005 by the Alaska Department of Fish and Game Faunal Assemblage Structure on the Patton Seamount (Gulf of Alaska, USA) Gerald R. Hoff and Bradley Stevens ABSTRACT: Epibenthic and demersal assemblages of fish and invertebrates on the Patton Seamount in the Gulf of Alaska, U.S.A., were studied in July 1999 using the Deep Sea Research Vehicle Alvin. Faunal associations with depth were described using video analysis of 8 dives from 151 to 3,375 m. A cluster analysis applied to the observations suggests three benthic faunal communities based on depth: 1) a shallow-water community (151–950 m) consisting mainly of rockfishes, flatfishes, sea stars, and attached suspension feeders, 2) a mid-depth community (400–1500 m) also consisting of numerous attached suspension-feeding organisms such as corals, sponges, crinoids, sea anemones, and sea cucumbers and fish such as the sablefishAnoplopoma fimbria and the giant grenadier Albatrossia pectoralis both of which were aggregated over a relatively narrow depth range, and 3) a deep-water community (500–3,375 m) consisting of fewer attached suspension feeders and more highly mobile species such as the Pacific grenadier Coryphaenoides acrolepis, popeye grenadier C. cinereus, Pacific flatnose Antimora microlepis, and large mobile crabs Macroregonia macrochira and Chionoecetes spp.

  • Market Update
    MIXED PROGRESS IN 2008 ALASKA FLATFISH FISHERIES When the North Pacific Fishery Management Council (the Council) cut the 2008 Bering Sea pollock quotas by 28%, it supplemented the total all-species quota in the Bering Sea with major increases to quotas of various flatfish species. Although these flatfish species command lower prices than pollock or Pacific cod, the Council felt increased flatfish quotas could somewhat offset quota holders for the lost pollock revenue. Here is a table showing the 2008 quotas of several major Alaskan groundfish species: ALASKA GROUNDFISH TOTAL ALLOWABLE CATCH (TAC) 2007-2008 all figures in metric tons (MT) % 2007 2008 change Species BSAI GOA Total BSAI GOA Total Total Pollock 1,413,010 68,307 1,481,317 1,019,010 60,180 1,079,190 (27.1%) Pacific cod 171,000 52,264 223,264 170,720 50,269 220,989 (1.0%) Yellowfin sole 136,000 136,000 225,000 225,000 65.4% Arrowtooth flounder 20,000 43,000 63,000 75,000 43,000 118,000 87.3% Northern rock sole 55,000 55,000 75,000 75,000 36.4% Flathead sole 30,000 9,148 39,148 50,000 11,054 61,054 56.0% Alaska plaice 25,000 25,000 50,000 50,000 100.0% Atka mackerel 63,000 1,500 64,500 60,700 1,500 62,200 (3.6%) All other species 87,315 95,693 183,008 112,915 96,823 209,738 14.6% Total 2,000,325 269,912 2,270,237 1,838,345 262,826 2,101,171 (7.4%) Notes BSAI Bering Sea / Aleutian Islands area GOA Gulf of Alaska area Stalled yellowfin sole fishery Despite the quota increases, trawlers in Alaska have yet to fill their pollock shortfall with flatfish, due mainly to a slow start to the yellowfin sole fishery.

Buser, B.Sc. Fairbanks, Alaska May 2014 v Abstract The sculpin subfamily Oligocottinae is a group of 17 nearshore species and is noteworthy for the fact that it contains both intertidal and subtidal species, copulating and non- copulating species, and many species with very broad geographic ranges. These factors, as well as the consistency with which the constituent genera have been grouped together historically, make the Oligocottinae an ideal group for the study of the evolution of a reproductive mode known as internal gamete association (IGA), which is unique to sculpins. I conducted a phylogenetic study of the oligocottine sculpins based on an extensive molecular dataset consisting of DNA sequences from eight genomic regions. From the variability present in those sequences, I inferred phylogenetic relationships using parsimony, maximum likelihood, and Bayesian inference. Results of these phylogenetic analyses show that some historical taxonomy and classifications require revision to align taxonomy with evolutionary relatedness.

  • BC Page1 BC Ferries Departure Bay Passenger Facilities
    BC Ferries Departure Bay Passenger Facilities | Nanaimo, BC Clive Grout Architect Inc. This BC Ferries’ project consists of a 28,000 sq ft building which includes ticketing and arrivals hall, baggage pick up and drop off, departures/arrivals corridor, retail shops, food court, washrooms, waiting lounge and escalator connection to the ship’s load/unload gangway. The project also includes an exterior courtyard and children’s area. Retail and food facilities are accessible to both foot and vehicle passengers. Wood was an excellent choice for ceiling and exterior fascia material as the architects desired to introduce a signature material to the landside facilities symbolic of the land and mountains of coastal B.C. as a contrast to the experience of the sea on the ships. In creating an image for the new passenger facilities, the architects selected the warmth and comfort of wood expressed on the ceiling, leaving the floors for utilitarian finishes and the walls for full glass to integrate visually with the spectacular setting on the edge of the water. The dramatic shape of the building and its roof, dictated by the site planning constraints, is enhanced by the prominence of the wood panels. The architects took two key steps to ensure the long-term durability of the fir veneer in coastal B.C.’s sea air and rain environment. The fascias are designed to slope sharply from the edge, keeping them out of the line of the direct rain. The entire assembly was initially rigorously and successfully tested by Forintek Canada for boiling water emersion, dry peel and room temperature delamination, giving the client and architect confidence in the application.
