You can simply ask fisherman about what is going on with their catch. People tend to side with scientific data, that can be outdated or wrong, rather than asking simple man about their own experiences.

We need to learn to ask "regular people", to make big scientific projects like this to work.

I would be surprised if our current measurements of fishing and fish populations did not involve data from fisherman.

Right because i’m sure the fisherman doesn’t have any bias when he or she answers the survey questions. Including the wholly unscientific opinions of “regular people” is not a solution that will lead to better scientific understanding.

Using data from regular people as a PART of such a research would help tremendously in my opinion. People do not need to know why this data is gathered when answering it.
