Abstract:
The workshop in Dublin in April 1991 developed from discussions amongst members of the Atlantic Salmon Trust Honorary Scientific Panel which had been taking place over a number of years. The report begins by addressing the problem of assessing the numbers of fish caught. Although catch statistics do not themselves indicate levels of exploitation, they are the basic measure of the performance of salmon fisheries. In some situations they represent the only data on fisheries or stocks that are routinely collected every year. This section considers the difficulties of obtaining reliable catch statistics and possible approaches to improving their comparability and completeness. The report then considers exploitation; first by describing the terminology; then by discussing how it may be estimated; and finally by examining some of the levels recorded in commercial and sport fisheries. Sections 5 and 6 provide estimates of the exploitation rates on a number of stocks in various commercial and sport fisheries. These data highlight the complexity of the life cycle and behaviour of salmon. The problems of comparing and combining exploitation rates in different fisheries is discussed briefly in section 7. The final part of this report (Section 8) considers the implications of the various observed levels of exploitation for fisheries management.
