§ Mr. Dalyellasked the Secretary of State for Scotland what progress has been made at Faskally Research Centre, Pitlochry, into the improvement of brown trout fishing.
§ Mr. RossIn the course of its work on factors affecting the number, size and growth of brown trout in Scottish waters the laboratory undertook a wide range of research on such matters as the biology and behaviour of trout, their food requirements, the conditions under which they spawn and the productivity of Scottish freshwaters, including chemical fertilisation of lochs, control of aquatic weeds and elimination of predators. A great deal of information on these and other factors of value for the management of trout waters was obtained and published. Although its work has for some years been mainly concerned with salmon, the laboratory continues to be engaged in experimental trout improvement schemes and to advise angling clubs and proprietors on trout matters.
