In order to detect periods of synchronous gene expressions during embryogenesis of Oncorhynchus masou (Yamame), we analyzed the peptide constituents of the embryos by means of two‐dimensional electrophoresis. New kinds of peptides were mainly detected in three periods, i.e. between the 12th and 13th day, between the 20th and 21st day, and between the 30th and 31st day after fertilization. Hatching occurred between the 34th and 37th day. These indicate that these three periods, which corespond to (1) the shifting stage from maternal to nuclear events in gene expression, (2) the development of external organs such as fins, and (3) the preparative stage for hatching, respectively, may be critical stages in gene expression.
