Population structure over time

Thanks to Art Butts at Idaho Fish and Game we have the data of the rainbow trout fishery from the last five population sampling efforts, conducted every three years since 1997.  We display each sampling effort in a separate chart and it automatically cycles through the slide show.

Each chart displays the percent distribution of trout by size for each year of sample.  The information is useful to visualize shifts in population characteristics.
