At five in the morning, the fishermen are already setting the nets.It's time to take the plunge.It may seem a little strange why we're putting fishing net on our scuba gear, but it has a very useful purpose.These jagged edges of the gear are completely covered with this fishing netto prevent us from getting snagged and caught like fish.I don't normally wear a knife this big, but in this kind of situation,with all the nets around and the possibility of entanglement, it's a really good idea.This is a shark shield, and with a tuna-fishing boat,thousands of bloody tuna in the water,and a sea full of sharks, it could come in very handy.They enter the net.Despite having done all they can to prepare, this is a jump into the unknown.The scale of the net is breathtaking.They're relieved to find that there are no sharks this time.But there are also no fish.
