Monitoring discrete fixed locations requires automated receivers and data loggers while manned, mobile receivers are more suited to general movement or habitat studies. Of the three tagging methods available; external attachment is best suited to long term studies on feeding fish where tag weight can be kept under 1.5% of fish weight, stomach placement of transmitters is best suited to non-feeding fish on spawning migrations or short term studies where impacts on feeding are not a concern, while surgical implantation in the body cavity has applications in both areas but incurs a high tag loss rate and potential disease problems.
