    Notes: [Auszug] AN examination of hyperfine structure in the visible lines of the Ga II spectrum with a Fabry-Perot interferometer has shown the patterns due the individual isotopes to be distinctly separated by a difference in the magnetic moments of the nuclei. This permits the mechanical moments to be ...

    Biology of the emerald shiner Notropis atherinoides Rafinesque in Lake Simcoe, Canada (1970)

    Notes: The study of the emerald shiner Notropis atherinoides Rafinesque was conducted in 1967 and 1968 in Lake Simcoe, a eutrophic inland lake with an area of 725 km2 situated in the Province of Ontario, Canada. On the basis of meristic characters, the emerald shiner of Lake Simcoe conforms to the classical description of the species and is not distinct from the form inhabiting the Great Lakes. Annulus formation occurred in early June on age I fish but second and third annuli were not formed on older fish until late July through August.Young-of-the-year emerald shiners reached a total length of 45 mm by October; age I were 81 mm and age II measured 92 mm by the same month. By September, age I female emerald shiners attained a size superiority of 5 mm over males of that age group and by the end of the third summer age II females exceeded age II males by 8 mm. Spawning occurred offshore in the latter part of July when surface water temperatures approximated 20°C. Of the three age groups, age II specimens were the most prevalent on the spawning grounds. Average absolute fecundity was 3410 eggs in fish of all age classes combined. Differences in water temperature seem to strongly influence the seasonal distribution pattern of the emerald shiner. The final temperature preferendum of the species, as determined in a vertical temperature gradient tank, was 25°C. The emerald shiner is extensively utilized as a bait fish by anglers and appears to be an important forage fish. The plasticity of the species to adapt to a variety of ecological conditions and the species potential for high production favour its introduction to waters requiring a good converter in the food chain.

    Spawning characteristics of brown trout and sea trout Salmo trutta L. in Kirk Burn, River Tweed, Scotland (1977)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of fish biology 11 (1977), S. 0

    Topics: Biology
    Notes: The upstream spawning migrations of brown trout and sea trout were studied using stationary traps placed in Kirk Burn, a tributary of the upper Tweed. The sea trout spawning period extended from early November to the first week of December, while that of brown trout occurred from the middle of October to the third week of December. Sea trout were predominantly maiden spawners of ages 2.1+ and 3.1+ while brown trout were mostly age 2+ and 3+. Male-female sex ratios approximated 1:1.4 in sea trout but 6 : 1 in brown trout. Brown trout males participated in the spawning activities of sea trout. Low water conditions in Kirk Burn hindered the upstream movement of spawning sea trout, while sudden increases in water level appeared to stimulate the upstream migration of both brown trout and sea trout. The suggestion is advanced that the freshwater resident brown trout of the Tweed which migrate upstream into the smaller tributaries to spawn is wholly, or at least partially, the progeny of anadromous parents.

    Notes: The concepts and potential advantages of local and global least squares smoothing of discontinuous finite element functions are introduced.The relationship between local smoothing and the ‘reduced’ integration' technique is established.Examples are presented to illustrate the application of the two smoothing techniques to the finite element stresses from several structural analysis problems.The paper concludes with some practical recommendations for discontinuous finite element function smoothing.
