I have a question and would value your thoughts to how best address this. What do you think would be the best way to demonstrate the positive impact of a bycatch reduction device on local populations (of sharks). Have CPUE and length data. BRD significantly reduces CPUE for some species but wonder if there is a way to show the benefit (if any) to the population in a numerical sence.
I have some ideas and would value any of your opinions.
