To those new to diving, there are some things you should know about sharks and shark behavior when reading the opening post.
1. The diver is talking about collecting fish for an aquarium. When you net fish as he does, they send out distress signals. This attracts sharks. The people who are most involved with nosy and somewhat aggressive sharks are spearfishers and fish collectors for that reason.
2. The diver is talking about doing photography. It has been well documented that there seems to be something in photography, possibly the strobe action especially, that seems to attract sharks. Sharks have senses that may be picking up on the electronic actions of the camera equipm

Divers who are doing neither rarely draw much interest from sharks.
