Mugil cephalus (gray mullet) is a euryhaline fish that is cultured successfully in fresh water, brackish water and sea water. However, the culture of this fish is closely dependent on the availability of wild fry. The fluctuating amounts and capricious nature of the fry supply in the last few years has prompted investigation of artificial spawning of broodstock in captivity and mass propagation of the larvae (Shehadeh and Ellis, 1970; Kraul, 1983; Lee et al., 1987; Tamaru et al., 1989; Lee et al., 1992). Most investigations have concentrated on the induction of spawning under natural conditions at the peak of the fish’s normal breeding season (Kuo et al., 1973; Kulikova and Gnatchenko, 1987; Suzuki et al., 1991).
