To understand the capture process of different types of fishing gear, and to design the gear and aquaculture facility to improve the efficiency of fish production, it is important to obtain data on fish behaviour regarding their response to the fishing gear and aquaculture facilities used. There have been a number of research studies on the dynamics and catching capability of fishing gear. On the other hand, owing to the behavioural measurements in fisheries research, and the appearance of biotelemetry and bio-logging technologies, it has become possible to determine the behaviour of fish near/within the vicinity of fishing gear and in an aquaculture facility. To obtain a scientific understanding of the response of fish to fishing gear and aquaculture facilities, it is necessary to detect the position of the target fish to confirm its specific positional relationship with the fishing gear and aquaculture net cage. This paper introduces behavioural measurements using biotelemetry, bio-logging, and video analyses established by the author that can be used to detect the position of a fish for fisheries and aquaculture research. It is believed that these behavioural measurement techniques will be useful for fisheries engineering as a new biological approach.
