Electronic data storage tags (DSTs) were used to monitor natural behaviour of adult yellowtail flounder (Limanda ferruginea) in relation to depth, temperature, time of day, and season. Over a 2-year period, a total of 543 fish tagged with DSTs were released during June of each year. Results from 29 tags revealed that yellowtail flounder exhibit diel and seasonal variations in depth and temperature. The results also show, for the first time in this species, that during various times of the year yellowtail flounder make extensive off-bottom movements at night and can remain off bottom for several hours.
