Summary:Mysids, small shrimp-like crustacea, proved to be a practical bioassay animal for investigating the effects of cadmium in seawater and may serve this purpose for other pollutants. In the laboratory under flow-through test conditions, the mysid, Mysidopsis bahia, was more sensitive to cadmium than other crustaceans tested. LC50 values were 15.5 microgram/l within 96 hrs and 11.3 microgram/l during a 17-day life cycle, whereas LC50's for other selected crustaceans were between 120 and 720 microgram/l. Results of life-cycle bioassays can aid in the establishment of water quality criteria for marine and estuarine organisms.
