I remember us talking about your shark encounters and your avatar years back. That type of diving trip is something to see. The sharks are conditioned in those situations. Before 3 hurricanes destroyed basically everything on my favorite island in the Bahamas (Walker's Cay), they used to do a daily shark rodeo. They would drop a frozen block of fish parts down in about 45 feet and the divers would be positioned in a semi-circle around it sitting on the sand. They have nothing on that awesome island anymore except for a tiny airport. The sharks are all still there though. They'll steal fish right off of the tip of your spear.
When spearing fish there we have to make sure that someone is running the boat (no anchoring) so that when you come up with a fish, the boat comes to you as quickly as possible in order to get the fish and it's blood trail out of the water fast. We also make sure not to hold the speared fish against our bodies... we hold them as far away from ourselves as possible to avoid having a shark miss the fish and accidentally hit us.
That time I had to hand feed my snapper to a big bull was not something I meant to do, or would ever want to do again. It happened when I first started going over to the Bahamas and my buddy and I thought we could break a few rules... like using tanks and spearing fish. You can't use air over there and spear something,,, you have to free dive if you want to kill anything unless you are a Bahamian citizen. Anyway, we anchored the boat on the front side of a big reef that was only about 3 feet deep or so on the top of it. The reefs there are like submerged islands. On the back side of this reef it dropped off very deep. We put on our tanks and swam across the reef and dropped down the back side. I speared the fat snapper and proceeded to try and swim back to the boat along the top of the reef. The tide was ripping out at a very strong rate so I couldn't just swim it,,, I had to actually stand up on the reef and walk my way back. It was at least 40 yards to the boat and I couldn't get there fast. My brother-in-law was snorkeling across the top of the reef near me and I noticed that he was acting very strange and spinning in circles while thrusting his pole spear. He was trying to keep the big bull shark away from him because it was coming at him aggressively and obviously looking for the fish I has on my spear. He yelled over to me and I then realized that I had a problem... the problem got bigger when I saw how big and aggressive this bull was, and I was having a very hard time getting the spear out of the snapper because of the spring out barbs that are supposed to keep the fish on the spear. It was a miracle that I was able to get the spear out just as the shark came up to get it. He was going to get a big bite of something if it wasn't the fish he was smelling. Insane.
That was the last time that I ever speared anything there while using the aid of air. Lesson learned and burned into memory.
