Those are both good points.
You know it's kind of weird for me as it's such an old issue for me. I just posted kind of the same thing I've been saying for over a decade.
Honestly I've not been keeping up or looking for new information when it comes to T's and Mercury. The last thing I read on mercury was a few years ago and it said that adult T sharks were not as bad as tuna or swordfish when it comes to bio-magnification, but that's now old information.
As to the male shark idea: Yes you are absolutely right if if you want to harvest sharks, it's preferable that you only take males. I should of said something about that in my post. Females carry the young one male can mate with many females.
You might find this interesting but I feel the same way about lobsters. Same idea one male can mate with many females. I occasionaly keep smaller females when hooping is very slow but if possible I release all my females and never keep big females over three pounds. The larger the tail the more eggs they can protect and carry. On the other and I have no problem killing big males as larger males are canibilistic and eat their own young.
