formaldehyde gas dissolved in water used as a fixative and preservative in fish collections as decay bacteria cannot live in a 5-10% solution of it.

Also used in the control of external parasites and fungal infections of fish and eggs in aquaculture. Formalin is a noxious chemical and should be handled with appropriate safety measures
