Tricaine, also known as MS-222 or ethyl 3-aminobenzoate, is a widely used anesthetic in aquatic environments, particularly in fish and amphibian research. This compound is essential for researchers and aquarists, as it provides a humane method for sedation during procedures such as tagging, transport, and surgical interventions. Tricaine is favored for its rapid onset and effective anesthetic properties, allowing for quick recovery times, which is crucial in maintaining the health and well-being of aquatic species.

In addition to its applications in research, Tricaine is also utilized in aquaculture for the safe handling of fish, minimizing stress during harvesting and processing. Its effectiveness in reducing stress responses makes it an invaluable tool for professionals in the field. The compound's unique ability to provide a non-toxic, water-soluble anesthetic option distinguishes it from other anesthetics, ensuring that it is both safe for the environment and effective for its intended use.
