Jim,
Very interesting take on keeping the big vs. the small. Definitely makes me rethink my usual train of thought that the big breeders are the ones to leave alone. What's the deal with mercury levels in the big ones though? Those big threshers have been around a long time eating and bioaccumulating. I think I'd rather feed the neighbor's wife and kids with a smaller one, at least from a health perspective.

I think the more important idea is to try and only keep males, that is if you want to harvest threshers. They are VERY easy to identify with those huge claspers no matter what their size. Game managers have been managing deer and other large game for a long time by only allowing the harvest of males, and it seems to work well for the population. Maybe the same should happen with some species of sharks?
