This volume, the Proceedings of the Fourth International Atlantic Salmon Symposium, addresses two major issues: what happens to salmon smolts after they reach the sea and, in particular, what factors determine their survival in the sea. what promising new methods are being developed for the enhancement of freshwater production of salmon juveniles? Comprehensive and international in its coverage, this volume provides a detailed review of the marine life of salmon and contains a wealth of information on new salmon enhancement strategies supported by case-studies. This reference is for fisheries managers and fisheries scientists and belongs on the reference shelves of the appropriate institutional and government libraries.
