A new acoustic pH transmitter for studying the feeding habits of free-ranging sharks

  title={A new acoustic pH transmitter for studying the feeding habits of free-ranging sharks},
  author={Yannis P Papastamatiou and Carl G. Meyer and Kim Nicholas Holland},
Little is known about the feeding habits of large free ranging fish, due in large part to lack of an appropriate technique for quantifying feeding variables. A previous study demonstrated that changes in gastric pH can be used as a proxy for feeding events in free-ranging sharks. Here we describe the development of a new acoustic pH transmitter to remotely measure gastric pH in sharks in the field. The transmitter consists of a dual sensor (pH and temperature) continuous pinger, and was tested… CONTINUE READING
