 The most comprehensive use of acoustic fish telemetry has been done on the large scale 1D migration research. In this setup hydrophones are spread along a lake, a river or a canal and fish are detected when passing these hydrophones. Numerous examples of fish migration studies in large rivers and lakes around the world have been published so far. The advantages of this research technique are found in its good performance in deep and salt water and its large detection range in such situations. Many of these migration studies were conducted on diadromous fish species like eel and salmonids. The typical study design consists of 69 kHz hydrophones and tags with a diameter between 7 and 13 mm. The hydrophones can be moored close to the river banks if the detection range of the tags covers the whole width of the river. In lake or estuary systems, hydrophones can be attached to buoys. This range depends on the tag output power (136-162 dB) and the environmental conditions (noise). Tags are custom-made and programmed to fit the research demands. The determining factors for the setup of a 1D acoustic system are the fish species of interest, its environment and the specific research questions. When studying smaller species or juvenile fish, tag size will limit the battery life. Big rivers with strong currents will require more hydrophones and/or tags with a higher output (so a shorter battery life). When spatial and temporal changes of a certain migration are expected, tags could be programmed in different steps in which the duration, the power output and the signal delay can be changed. During or after the study period, hydrophones have to be lifted for data download by means of Bluetooth connection to a PC. Hydrophones at 69 kHz can operate for more than one year before the battery has to be changed. A single hydrophone can store 1.6 million detections. These unique detections are the result of a so called ‘PPM’ signal (Pulse Position Modulation), which is a ping train of 8 consecutive pings. The separation between each of these individual pings results in a unique ID. The recently developed tags and hydrophones that work on 180 kHz can emit and detect HR (High Residency) coded signals beside PPM coded signals. An HR coded signal is emitted as one ping and does not exist of consecutive ping trains. Hence, the emission time of the code is reduced much and one signal is emitted in less than one second. Consequently, the chance of collision of codes of multiple tagged fish that are within the same detection zone of a hydrophone is reduced. Next, the delay between two consecutive code emissions can be reduced as well, down to one second, allowing more frequent fish positioning (more fish positions per time unit). High frequency tags are smaller compared to the 69 kHz tags (smallest tag diameter is 4 mm). A network of receivers can be used to conduct research on several species at a large scale (Figure 3 and 4).
