Yesterday we took one of the boats offshore and trolled around the 300' depth line. There aren't any fishing rods on the island, so instead they've attached lengths of parachute cord to large hooks and secured them to the boat cleats.
We were almost immediately gratified with a zing on the line and worked furiously to pull in the line by hand. Unfortunately two sharks got to our fish first and took off the back two thirds of what was probably a 70 lbs wahoo. Then we hooked one of the Galapagos sharks - which was exciting. The bugger had taken the hook pretty good, so it was quite a fight to get it out and let him go.
By the end of the afternoon we'd kept 3 and 1/3 wahoos, one rainbow [threw him back] and a shark. When we got back to the pier, a few experts sliced up the wahoo into different types of cuts. They also kept the heads an most of the organs, since the Thai guys will use them to cook with. The rest of us gorged on sashimi so fresh there was still blood oozing from it - yum!
