What do the three subjects in the title of this podcast have in common? They're all important aspects of the work being done by Sean Simmons and Angler's Atlas. On this episode of Dam!, Sean explains Angler's Atlas, discusses the importance of citizen science, how the MyCatch app and angling tournaments are bringing in valuable fish data, and how he hopes to use similar methods with the Salmon Prize–a competition aimed at producing models that can better predict salmon returns.
