Author: Salmon Advisory Committee
Document Type: Monograph
Annotation: Co-published with the Scottish Office Agriculture, Environment and Fisheries Department and the Welsh Office Agriculture Department
Abstract:
This Salmon Advisory Committee publication identifies significant predators of salmon in respect of which the Committee might be able to offer advice relevant to the protection and development of salmon fisheries. Also it reviews and comments on the current understanding of predation on salmon, and to advise on research needs. In this report predator is define as an animal which gains its main sustenance from killing and eating other animals. Salmon exist within a community of animals and are themselves predators. However, they are also preyed upon by a variety of other species throughout their life cycle. Predators may influence the production of smolts and their survival to return as adults, which will in turn affect net and rod fisheries and the number of salmon that spawn. We are well aware that factors other than predation may also influence the production and survival of salmon. For example, changes in water quality, stream flow and the nature of the river bed may affect very profoundly the capacity of a river system to support salmon. Such matters are, however, outwith the scope of this report.
