    Description: For conservations of nature to be effective. there must be an understanding of what is present to be conserved. Thus in order to conserve the communites of the Cumbrian rivers, there must first be surveys to determine the spp present and their relative numbers. This has been carried out for many years, by a number of workers. It has been shown that the communities present are influenced by the substratum, the flow, the chemicals present, water temp and predation. Findings of the work on the River Lune were given at a seminar on the rivers of north-west Europe, held at Amiens in November, 1975. The proceedings of the seminar are to appear in special numbers of Bulletin francais de Pisciculure.

    Description: It has been estimated that in England and Wales fresh water covers some 340 square miles of which about one quarter is inhabited mainly by salmon and trout; in Scotland the lakes cover an area of 340 square miles. The principal object of this publication is to make available in handy form some of the methods, especially those involving the use of manures, by which crops of fish from water can be increased. The cultivation of water which this implies may be compared directly to the cultivation of farm land: the conditions for growth are made as favourable as possible, the seed is sown in the form of young fish, and after one or perhaps two growing seasons the crop is harvested. There are however many waters about the country where marketable fish are already available and can be removed without prejudice to, and indeed to the advantage of, sporting fisheries. In such cases it is necessary only to remove the fish and to rely on the natural processes of reproduction of those which are left to repopulate the water. Farming waters in the true sense is the concern of the greater part of this publication; the removal of crops of otherwise unwanted fish is considered in the last two sections on perch trapping and eel fisheries.

    Publication Date: 2021-07-08
    Description: An update on the work undertaken by the authors, Macan and Hynes, over the past year. Macan provides details of additional work undertaken since his publication of faunistic work on adult animals, including details on additional field data, further developments of the conclusions intially drawn and further comparisons with fauna of the highlands of Scotland. Two histograms are provided showing succession of Corixidae in two separate waterbodies. Habitat conditions are also discussed for this species and a number of locations are mentioned including, Blelham Tarn, Derwentwater and Rusland Moss. An update on stonefly work undertaken by Hynes is provided, specifically stomach contents of nymphs and habitat preference. Details are also given of aquatic insects being breed by the staff for research.
