The period of activity of mullet spermatozoa suspended in seawater was similar to that of sperm suspended in osmolar equivalent dextrose solution or artificially prepared seawater. Sperm activity was longest in solutions of pH and osmolarity closely approaching that of normal seawater. Temperatures lower than those at which spawning normally occurs greatly increased the period of activity. Undiluted milt stored at 10° C couid be activated by the addition of seawater for a period of 36 h.
