Two thoughts. First, as an instructor teaching in the waters of Monterey Bay, Califonina, it became well know that there were several seals, that when hearing the click of the bands on a gun, or the twang of a pole spear, knew the sound of the diner bell. Many divers lost their kill and sometimes their weapons. Sharks can be trained. A cautionary tale. Second. Between all my dive partners in Hawaii, all of whom are spear and trap fisherman, (I don't) there have been 10's of thousands of dives, and not one shark "hit". Close encounters of the terrifying kind, but no hits.There may have been other spearfishermen hit, but none that I know of since 1977. However, while deco for 90-120 minutes drifting in the Auau channel off Lahaina, Maui we all have been watched very closely by very large tigers. Some more agressively than others, coming within 3-4 feet and making a quick turn. For a long time we carried bang sticks or billy clubs, and never used them. Numerous times on the bottom while working, I would look up and see several tigers making big circles, slowly. At any time if ANY shark want's you or what you have, it will take it, and very quickly. There is no question that sharks are programmed to be attracted by the various stimuli of its prey, and thats the chance you take when killing fish and they make diner bell sounds into the deep.
All that being said, if you continue to kill fish, you might consider a very long stringer, and the shark will hopefully go for your catch. Carry a short billy with spikes and practice with it, the first time you need it should not be the learning time. Wetsuit material does not emminate in the shark food register, although a quick bump and test nibble is always possible. Sharks, like people, do not like being hit in the nose, nor do they like loud and unknown noises coming at them from large strange shaped objects. Buddy up and scream. Sometimes in the moment thats hard to remember.
Hope these few thoughts are helpful. Oh yeh, remember to breathe, and exhale on the way up.
