Most of the comments here mention divers, I would have expected thus to be focused on fishing. When I lived on the gulf coasts there were quite a few sunken ships marked as common fishing spots.
In some areas a lot of nets and other fishing tackle ends up snagging on shipwrecks. This "ghost fishing" gear still ends up killing a lot of marine life. The Ghost Diving Foundation has been cleaning that up but it's a slow and expensive process.

Its all deep sea fishing around there, you drop a line near the artificial reefs looking for bottom feeders.
