Résumé : The overall objective of this guide is to serve as a user manual for interpreting
the scales and estimating the age of brown trout (Salmo trutta) from the French trout
populations. Three biological forms of brown trout, river, lake and sea, have colonised
a large number of aquatic environments in France, owing to a high ecological plasticity
of the species. Following a presentation of the species, its ecology and its life-history
strategies, this document describes in detail the structure of trout scales and the
methods for collecting, preparing and mounting scales. Definitions of scale structures
and a standard notation system for age are proposed for the three biological forms.
This guide is richly illustrated with examples of typical scales from trout coming
from 39 rivers and three large lakes throughout France. Finally, the main difficulties
in estimating the age of fish are analysed via examples, including potential solutions
and a number of recommendations. [source éditeur]
