 Bringing a stingray, Dasyatis latus, on board for
transmitter attachment |
 Students measure the disc-width of this stingray |
Each ray is also given a Peterson-disc ID tag |
 After measuring and tagging, the stingray will be
fitted with an acoustic transmitter |
 Small coded pingers are attached to the ray with galvanized
wire and will fall off in a few weeks |
