Most fish surgeries are performed out of the water to facilitate visualization, tissue dissection, and suturing (Wildgoose 2000). Surgery tables adapted for fish should include a recirculating water system and a support element for the patient (Weber et al. 2009). The support element is typically made of nonabrasive material to preserve cutaneous mucus and should be permeable to allow water used for irrigation of the gills to return to a container placed underneath the table for recirculating systems (see Figure 5.2). For laterally compressed fish, a V‐shaped foam tray is useful to keep the fish in dorsal recumbency. Irrigation of the gills is performed using a Y‐shaped perforated tubing or two tubes connected to submersed pumps as previously described (Figure 5.2) (Weber et al. 2009; Mylniczenko et al. 2014). If an oral cavity procedure is performed, the tubing may be placed with retrograde flow in each opercular cavity with water irrigating the gills from their caudal aspect (Figure 5.3) (Mylniczenko et al. 2014).

Figure 5.2 Anesthetic equipment used for a large 8 kg koi (Cyprinus carpio) anesthetized for a surgical procedure: a Doppler probe protected by a glove filled with conducting gel is placed in the left opercular chamber for heart rate monitoring and two tubes, each connected to a submersible pump are placed in each opercular cavity.

Figure 5.3 Intervention in the oropharyngeal cavity of a Ranchu goldfish (Carassius auratus): a suture from a previous incisional biopsy is visible on the mass extending from the left commissure to left side of the face, ventral to the left eye. Irrigation of the gills is achieved with tubing placed caudally in each opercular cavity, which allows maintenance of anesthesia.
