Just to clarify, I was completely separating the idea that technology (specifically social media) has any direct impact on over-fishing. There is a ton of data on the fishing industry but none have linked technology to over-fishing because there is little to none. Over-fishing is a product of individualism (not thinking holistically) and loose policies, one of which is much more easily correctable. Someone earlier in the post mentioned that fisherman from shore would be the first to ever feel any impact on over-fishing or a "spot burn". Easy access and social media can definitely expose these spots which I can agree with, but I believe this is cyclical.
Raises a question for me to think about - Could fishermen who give up over time leave and the fish population regain its strength? Or it could be the total inverse like a gamblers fallacy, no fish but continues to fish because they assume that they should be catching post-skunk? (prime example being those who believe they will catch if they only cast one more time). Those who fish to catch give up when they run on a cold streak in my opinion (especially now that those with patience/persistence are a dying breed).
I am not totally discounting you as there is validity, but we use our experience to jump to improper conclusions (myself included).
