I think photographers can also cause the same wariness in fish behavior. Fish seem acutely aware of any aggression, even just staring at them.
Back in the 1940s, when JYC was first exploring his "Silent World," the fish would crowd around him and Dumas in curiosity. The divers began carrying pole spears to take a few fish each dive to supplement their wartime diet. The fish soon learned to stay just out of reach of the pole spears and were harder to catch. The divers switched to spear guns and, for a while, were bringing fish home for dinner again. That is, until the fish learned the range of the guns and started staying just outside that range. JYC noted that if the divers carried no weapons, the fish would crowd in just as before. But if the divers carried weapons, the fish would stay just out of range of that particular weapon. They would swim closer to a diver carrying a pole spear than they would a diver with a spear gun, and crowd right in on an unarmed diver.
