In this hands-on workshop we will demonstrate how to properly sedate and perform a physical exam on fish. These skills gained in this lab can be used in several species of fish. The goals of the lab include: 1. Safely calculate, prepare, and administer MS-222 sedation for individual fish 2. Recognize stages of anesthesia and monitor sedation depth 3. Perform a complete sedated physical exam on a fish 4. Collect basic diagnostic samples (skin scrape, gill clip, fin clip) 5. Discuss and/or assist with recovery and monitor return to normal behavior
