    Yield to Anglers of Spring and Autumn Stocked, Hatchery Reared and Wild, Brown Trout (Salmo trutta L.) (1979)

    Notes: Tagging experiments are described where hatchery over-yearlings and similar sized wild brown trout were spring-stocked in two small angling lakes. This was followed in the autumn with a stocking of hatchery fingerlings and wild fish. The spring-stocked hatchery fish gave the best return to anglers of 9.3% over the first two seasons, while the autumn-stocked hatchery fish apparently suffered heavy over-winter mortality — giving a return of only 1.3% over a comparable time period. Wild fish gave low return rates of 2.9 and 2.0% from spring and autumn stockings respectively, although netting exercises indicated that these survived longer in the lake than hatchery fish. Analysis of the methods of capture indicated that hatchery fish were more liable to be caught by bait fishing whereas fly fishing was the most successful for wild fish. Estimates were made of the relative cost effectiveness of the various types of fish in terms of returns to the angler.

    Seven years on – A continuing investigation of salmonid stocks in Lough Erne tributaries (1978)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of fish biology 12 (1978), S. 0 
    Details
    ISSN: 1095-8649
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: An electrofishing survey of Lough Erne spawning streams indicates a continued decline in the populations of juvenile salmonids. This is particularly the case with salmon stocks, which are now seriously depleted or absent from the sampled areas. This finding complies with the recorded decline in the adult salmon escapement to the Erne system. Stocking operations of both salmon and trout appear to have been successful in boosting recruitment only on a localised basis.

    Notes: [Auszug] THE middle Miocene was a time of widespread environmental shifts which resulted in profound changes in many faunal groups. The tropical and subtropical forests of the earlier Cenozoic had provided large and virtually unbroken tracts of lush, protective habitat for many animals. But by the middle ...

    Notes: [Auszug] THE fossil evidence for human evolution has been accumulating for almost a century and a half, and throughout most of this period the remains of fossil man have appeared in a slow, if not leisurely, procession. Thus, the slowly emerging record of human evolution could easily be assimilated by ...

    The second 2+ state in144Sm and the decay of144Eu (1976)
    Springer
    The European physical journal 276 (1976), S. 103-105 
    Details
    ISSN: 1434-601X
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract The positron decay of144Eu is reinvestigated using beta- and gamma-ray spectroscopy techniques. A decay scheme comprising three excited states and four transitions in144Sm is constructed. Three new transitions are observed and have led to the establishment of a second 2+ state populated in this decay. The half-life of144Eu has been accurately measured to be 10.2±0.1 s. Spin-parity assignments are made to all the levels involved in the decay. The structure of144Sm is discussed in the light of different models.

    Temperature gradients at the core-mantle interface (1973)
    Springer
    Earth, moon and planets 7 (1973), S. 14-21 
    Details
    ISSN: 1573-0794
    Source: Springer Online Journal Archives 1860-2000
    Topics: Geosciences , Physics
    Notes: Abstract Heat flowing out of the core must flow into the mantle. If the Earth's magnetic field is owing to adiabatic magnetohydrodynamic circulation of the outer core, whole mantle convection or melting at the core mantle boundary is required to keep the inner core from becoming isothermal, thereby preventing adiabatic circulation. Alternatively, the outer core fluid must have some unexpected and exotic property such as an extremely low coefficient of thermal expansion and resultant low Gruneisen's parameter.
