Salinity and oxygen tolerances of eggs and larvae of Hawaiian striped mullet (Mugil cephalus L.) were studied. Optimal salinities for eggs incubated at 19.5-20.5C were 30-32 parts per thousand by weight. Maximum larval survival occurred within the salinity range of 26-28 parts per thousand by weight. Significant decreases in egg survival occurred with eggs incubated in mean oxygen concentrations below 5.0p.p.m. and for larvae held in mean oxygen concentrations below 5.4p.p.m. The results are discussed in terms of spawning sites and the effects of oxygen saturation values on fish eggs and larvae.
