Mysids, small shrimp-like crustacea, are used as practical bioassay animals for investigating the effects of cadmium in seawater. In laboratory tests, the mysid (Mysidopsis bahia) was more sensitive to cadmium than other crustaceans tested. LC50 values were 15.5 micrograms/l within 96 hours and 11.3 micrograms/l during a 17-day life cycle; LC50's for other selected crustaceans were between 120 and 720 micrograms/l. Results of life-cycle bioassays with mysids can aid in establishing water quality criteria for marine and estuarine organisms.
