Bathing suits are not the only things that have gotten smaller in the past fifty years.
All these photos were taken on the same dock after fishing trips in the same waters. The last one was taken by post-doc Loren McClenachan, the rest were compiled by her from the records at Key West’s Monroe County Public Library.
Using the display boards as a size reference (they haven’t changed in half a century), McClenachan was able to plot just how much smaller trophy fish have become. The change is mainly due to changing composition of the catch - first fishermen target the larger species, and when their numbers have been depleted, they turn to a smaller species … and so on.
