Yeah, you are right; finding one is at least an indication that the species is still out there.
Gillnet fisheries can cause so much damage, not only to sharks, but to many other species as well.
And I agree with you. I don't know too much about your country Pakistan, but India certainly could need a lot of awareness campaigns. I think there is still hope to save some of these species if fishing them becomes more regulated, and people are aware of which species to not fish.
We are at the same level as far as awareness is concerned. Third world countries have many other issues to be addressed so government doesn't bother about these issues. Let's hope for the best
Oh, it's a lot of work left before you can see real change them I suppose :(
