Abstract
Time course data of the embryonic development of the round herring, Etrumeus teres, was described from fertilization to hatching at 20.0℃ for artificially fertilized eggs from adults sampled in Tosa Bay, southern Japan. The early blastula stage occurred at 4.3 h. The blastoderm covered more than half of the yolk at 15.1 h, the blastopore closed at 21.9 h and the embryo began to hatch at 64.2 h after fertilization.
