ALL UK PARCELS SENT TRACKED! ALL OVERSEAS PARCELS SENT AIRMAIL, TRACKED! (S/hand, Paperback, 2016). 2016 1st edition. 8vo (165 x 242mm). Pp87. Colour and b/w photographs, illustrations and maps. Pictorial card covers with flaps. Out-of-series copy from an edition limited to only 250 copies. A bumped unsigned out-of-series copy. A good reference copy. This book gives "an historical review of our knowledge of salmon. It briefly looks back to the times of Izaak Walton and Sir Walter Scott when various theories concerning the parr and smolt were raised as to whether or not they were the young of salmon. It follows on to record the experiments of Brown who reared and released parr and smolts on the Tay and confirmed them to be the young of salmon. The work of the early salmon biologists such as Calderwood, Menzies and Malloch is documented and leads us on to more recent investigations that require teamwork due to the effects on the freshwater environment of agriculture and industry. In this way more knowledge is accumulated and benefits further research and conservation, the results of which are discussed. The outcome of symposia and conferences are described and it is evident over time that the research was increasingly being centred towards the marine environment, particularly in Norwegian, Faroese and Greenland waters. The decline in salmon stocks leads to international concern through conservation organisations such as NASCO and the Atlantic Salmon Trust and it becomes obvious that conservation limits and stricter controls on exploitation are required." .…
