Seal-marking methods
For many years, in the course of fisheries investigations, large numbers of fish have been marked by means of numbered metal tags. Other marking methods, such as dyeing, branding and clipping of fins, have all been tried but found to be either unsuitable, or difficult of application, or less satisfa...
