Abstract

The overall purpose of this guide is to provide a manual for the collection and interpretation of sea trout scales. A brief introduction considers the advantages and disadvantages of using scales to determine age and growth. To ensure that scales are interpreted in a consistent manner, all major terms are defined and a standard system for age notation is proposed. The methodology for the collection, mounting and interpretation of scales is described in detail, and this is followed by a section on the back-calculation of lengths at different ages. Each topic is discussed critically. The final part of this guide is an atlas illustrating scales from a wide range of sea trout and including not only excellent "type-scales" but also difficult and impossible scales.
