Abstract

A novel marking scheme, using the Panjet inoculator and alcian blue for uniquely identifying large numbers of trout, was evaluated using a natural population of brown trout. This staining technique was found to be a quick, easy, reliable and durable method, having minimal effect on trout behaviour, condition or mortality, and permitted repeated capture and stomach flushing of individually identified trout over a period of twelve months.
