Abstract: The Empire fish Hypseleotris compressus (Krefft), Gobiidae, were reared four years in aquaria. Spawnings were induced by injection of a gonadotrophic hormone. The embryonic and larval developments were compared with those of the Japanese relative fish, H. cyprinoides (Valenciennes). Newly hatched larvae, being about 1.3mm in total length, were reared in both seawater and freshwater. The fish were fed with oyster-larvae, rotifers. Brine shrimps Artemia, harpacticid Copepods Tigriopos, and formula food being changed as they grew. Some larval fish grew to over 25mm in nine months and attained near the adult stage. The morphology of the early developmental fish, reared in seawater, is described.
