Monitoring the effect of water temperature on the heart rate of olive flounder (Paralichthys olivaceus) using a bio-logger

Evaluation of Post-Surgical Recovery in Olive Flounder (Paralichthys olivaceus) by Assessing Behavior, Heart Rate, and Wound Healing

“…This provides more information about individual animal behavior than ever before. More importantly, these devices are easily accessible [2,3] when they are attached externally [4][5][6][7][8][9] or inserted internally [6,8,[10][11][12][13][14]. Historically, when tags are attached externally, problems such as loss of the tag or increased risk of predation arise; therefore, the tag is often inserted internally through a surgical operation [6,8,[10][11][12][13][14][15].…”

Fish undergoing surgery for internally inserted tags, however, can become stressed during handling, anesthesia, incision and suturing, and recovery [1,3,15].…”

“…Fabrizio and Pessutti [25] compared the survival and growth of two fish species (black sea bass and summer flounder) according to their degree of exposure to clove oil, to evaluate recovery after surgery. In particular, recent studies with olive flounder (Paralichthys olivaceus)-a highly valued farmed fish in Korea-have focused on inserting tags into the body to quantify health information (e.g., stress-related endpoints) of the fish as part of the "smartization" of aquaculture systems [14]. However, very few studies have examined the impact of these tools on olive flounder or on the recovery process that follows surgery.…”
