FISH TRANSMITTERS

BODY IMPLANT - TRAILING WHIP ANTENNA

A body implant transmitter with a trailing antenna is surgically implanted into the body cavity through a small incision and is closed with sutures. The antenna either exits the body through a separate 1-2 mm incision or passes through the gill cover and is positioned backwards. This attachment method has been used on several different species of fish. Again, training is required to surgically implant the transmitter and there is a recuperation period for the fish. This attachment method also minimizes fish behavioral changes. Good field range is obtained through the trailing whip antenna.

EXTERNAL MOUNT

An external mount transmitter attaches to the fish through the musculature on the mid-dorsal region of the back at the base of the dorsal fin. This design is intended for fish who would be damaged by implanting a transmitter and whose habitat does not contain weeds to entangle the transmitter. Using an external mount transmitter can affect the fish's balance. Good field range is obtained through the trailing whip antenna.

Anterior and posterior attachment wires embedded into potting.
