  • Swimbladder morphology and buoyancy of Northeastern Pacific myctophids

    Creator:
    Butler, John Lawton
    Abstract:
    Of the common adult lanternfishes found off Oregon, two species have fat-invested swimbladders (Stenobrachius leucopsarus Eigenmann and Eigenmann 1890 and Stenobrachius nannochir Gilbert 1891), two species have reduced swimbladders (Lampanyctus ritteri Gilbert 1915 and Lampanyctus galis Gilbert 1891), two species have gas-filled swimbladders ((Protomyctophum thomp soni (Chapman 1944)) and (Protomyctophum...

  • The feeding habits of three species of lantern-fishes (Myctophidae) off central Oregon

    Creator:
    Tyler, Harry Raymond, Jr.
    Abstract:
    The feeding habits of the lanternfishes Tarletonbeania crenularis, Diaphus theta and Stenobrachius leucopsarus were studied by analyzing 1,735 stomachs from 54 collections from the slope waters off Newport, Oregon. Forty-one taxa of food items were identified. Euphausiids (Euphausia pacifica), copepods (Calanus spp. and Metridia lucens) and amphipods (Parathemisto pacifica) were...

  • Growth and reproduction of the lanternfish Stenobrachius leucopsarus

    Creator:
    Smoker, William Williams
    Abstract:
    Growth and reproductive patterns of the common lanternfish, Stenobrachius leucopsarus, are described by length frequency analysis, otolith analysis and examination of ovaries. Length frequency analysis, employing the probability paper method of analysis of polymodal distributions, of three and one-half years of monthly midwater trawl collections off Oregon showed that fish...
