Fig. 4From: Regional differences in oceanic migratory behavior of Japanese silver eel in waters with different vertical temperature gradientsThe temperature and depth profiles of four tagged eels released from the Sea of Japan coastline. The time series data retrieved from pop-up satellite archival tags are shown: A, B JZ1903, C JZ1901, D JZ1902, and E JZ1905. The tag type is represented in the parenthesis after each eel ID. A The depth–temperature time series profile retrieved from the X-tag are shown as the colored line. The gray shaded area denote nighttime and yellow triangle indicate the surfacing time of the X-tag. B–E The daily minimum and maximum temperatures recorded for each individual eel are represented by the gray bar linesBack to article page
