    Efficiency of Electric Fishing for Salmonids in Relation to River Width (1981)

    Notizen: The efficiency of electric fishing for salmonids was found to decrease with increasing river width. The results demonstrated that mean efficiencies in excess of 50% could be obtained using two anodes up to a river width of about 6.5 m and using three anodes up to a river width of about 11 m. Yearling and older fish were captured more efficiently than fry at equivalent river widths and this was discussed in relation to differences in their behaviour.

    Stomach Flushing of Salmonids: A Simple and Effective Technique for the Removal of the Stomach Contents (1981)
    Oxford, UK : Blackwell Publishing Ltd
    Aquaculture research 12 (1981), S. 0 
    Details
    ISSN: 1365-2109
    Quelle: Blackwell Publishing Journal Backfiles 1879-2005
    Thema: Land- und Forstwirtschaft, Gartenbau, Fischereiwirtschaft, Hauswirtschaft
    Notizen: A stomach flushing technique is described which has been used for over a year, both in the laboratory and in the field. It is reliable, quick and relatively easy to perform and has been applied to juvenile Atlantic salmon (Salmo salar L.) and brown trout (S. trutta L.). The only limitation on its use was that fish 〈4 cm in length were considered too small to flush. Experiments carried out show that the technique removes 98.9% of the stomach contents from the fish and has very little effect on subsequent survival (99.3%) and condition. It is suggested that this technique is an improvement on previous designs.
