Development of a methodology for efficient use of CW-tagging to quantify cormorant predation

The technology of coded wire tagging has been implemented in investigations of the level of cormorant predation. Previously only more traditional methods of estimating consumption by ear-stone and bone analyses have been used, but now we showed that tagging of a known number of prey fish combined with extensive sampling and scanning of pellets, can give much more accurate estimates of the effect of predation on given fish populations in the wild.
