When surgically implanting large acoustic tracking tags (HTI X-type) it’s essential to properly and securely close the incision to help prevent infection and tag loss. There are many suture materials and stitching techniques available to choose from. For this fish we are using antibacterial polyglactin braided suture with a tapered half-circle needle, and simple interrupted sutures suitable for closing large incisions. Adhesives are often used on smaller woulds, such as those for surgically implanting PIT tags.
