As I recall, the DFG says that leopards have to be at least 3' long to breed and, as with all fish, the bigger they are, the more prolific they can be. To me that means that for 'eatin' sharks', and there are few better than the leopard, you ought to stick to around the 4' size. This will allow the shark to have probably replaced itself at least once but leave the really serious breeders alone. Let's face it, the top predators have too low a reproductive rate to take much predation themselves. All the above conservation/environmental cautions taken into account, I have to admit that leopard shark is delicious and if I had one of the right size in my sights there'd be a "man eating shark" at my home that evening. Just for information, if you want to skin a shark the easy way, I have heard that after you brain it, stick the ball-inflator end of an airpump under the skin and inflate it off. Then you can cut the skin off neatly with shop scissors, head and gut it and then have perfect boneless 1" steaks for the BBQ clear down to the tail, not to mention shark fins for soup if you've got a Chinese cookbook around. Remember, no more than one per trip. 4 footers only. Eat what you kill.
Good hunting, brother, we be of one blood you and I--Kipling
