By Jessie Sanders, DVM, CertAqV Yes, even fish can undergo surgery. Be they small goldfish or large sharks, all species of fish can be diagnosed with conditions that require the need for surgery. Surgeries are not conducted under water, of course; most procedures are performed with the fish mostly out of the water, with anesthetized water flowing over their gills. Here are some of the amazing fish surgery cases that are being done. Broken Jaw Repair for Lemon the Goldfish Figure 1: Lemon prior to her oral injury Lemon, a fancy Ranchu Goldfish, presented to Aquatic Veterinary Services following a feeding session. During the feed, the right side of Lemon’s mouth collapsed into her oral cavity. Prior to the injury, Lemon had some oral deformities that had been with her since birth. Figure 2: Lemon upon presenting to Aquatic Veterinary Services Now, what to do for a 2-inch goldfish with a broken jaw? First, a specialty surgery bed made with bubble wrap was made for Lemon to lie on her left side. In order to ventilate her and keep her anesthetized during surgery, airline tubing was added to a 60-milliliter syringe to be hand-administered. A staff member was pulled in just to keep the syringes full.

Two small sutures were placed along the side of Lemon’s mouth to hold her jaw open. Figure 4: Lemon with the sutures in the side of her mouth post-surgery Following the procedure, Lemon was given pain medication and kept for a few nights in the hospital to monitor her healing and appetite. After a few days, she was allowed to return home and continue healing in her home tank with her buddy. Figure 5: Lemon two weeks after surgery with the sutures removed Two weeks post-procedure, the veterinarian went to see Lemon and take the sutures out. Following the removal, Lemon’s jaw was healed and no longer deformed.
