Tags and tools used, depicting comparative dimensions of a A passive integrated transponder (PIT) tag; B non-functioning model JSATS sturgeon transmitter acoustic tag (AT); C 8.5-gauge needle used to make a cavity to hold the self-powered tag (SPT). The black electrical tape marked 70Â mm from the needle tip, to ensure that the cavity created was longer than the SPT [65Â mm]); and D and E the SPT, depicting the front and back of the tag, with the circuit board shown on the right side of the SPT
