Tricaine Methanesulfonate
An anaesthetic for fish and amphibians, known as MS-222, used since the second half of the 20th century to handle them safely during research, surgery, marking and transport: it blocks sodium ions from entering nerve cells. This family brings together the active ingredient.
Did you know?It was born as a local anaesthetic for humans, an alternative to cocaine; in fish it enters and leaves by diffusion across the gills, and it is more water-soluble than benzocaine, which suits it to anaesthetic baths.
