Abstract
THE third Annual Report, 1934-35, describing the continuation of work on the lines approved by the Avon Co-ordinating Committee, has recently been published (University College, Southampton. Avon Biological Research. Annual Report, 1934-35. Pp. 126 + 3 plates. Southampton: University College, 1936. 2s. 6d.). The work is conducted at University College, Southampton, where there are special laboratories set aside for the purpose, and on various parts of the river; the main purpose being salmon research and its branches, although trout research is also included. The salmon research is approved by the Development Commissioners, who since October 1834 have kept it under their official supervision, the Treasury having granted a sum towards the expenses enabling, among other things, a junior research officer to be appointed. Much help is acknowledged. Colonel Bennet- Stanford has erected a hatchery and provided Facilities for the freshwater rearing of salmon in his lakes at the head waters of the Nadder, a tributary of the Avon, more than fifty miles from the sea, and many others have assisted substantially, both financially or by individual work and advice. A rotating fish screen (described in the appended papers) has been set up on Major Napier's land at Fording -bridge, where also are experimental spawning beds. East Mill still remains the headquarters of the river. The general report deals with the importance of vermin, artificial propagation and smolt migration. Appended papers include “British Mammals and Birds as Enemies of the Atlantic Salmon” (a most interesting and important summary), and “Importance of Iodine in Relation to Fish”, besides accounts of hatching and stocking experiments and of scales from the Avon trout and grayling.
