The way we did that was to get a perforated drum which is full of bait, wrap it in a neoprene skin, and then run two stereo underwater cameras to watch how the shark actually engages with that rig.
Lo hicimos con un tambor perforado lleno de cebo, revestido de neopreno, y luego pusimos dos cámaras estéreo subacuáticas para ver qué hacía el tiburón con el cebo.
