| This POP-UP TAG is made for Japanese eels. The weight of Japanese eels is about half of European and American eels. The weight of this POP-UP TAG is 32.5g. It is about 70% of American TaG. This POP-UP TAGs send last 10 days raw data after pop-up to ARGOS satellite. |
| 1. Investigate the depth data pattern when eels are spawning. It is said that eels spawn on the night of the new moon. Set the pop-up date to a special new moon night + 5 days. A special new moon night is the night when eels are likely to spawn. Try several times to get a depth waveform of spawning eels. 2. Analyze the depth waveform to identify depth data patterns during eel spawning. 3. Create an algorithm to detect the spawning of eels. 4. Change the program of this pop-up tag to detect eel spawning and pop up.@ |
