Abstract

The following is a detailed study of the 6 mm Wall-eyed Pike. The organs and organ systems are presented and discussed in the same serial order that they appear in the embryo beginning at the anterior end and proceeding posteriorly. There has apparently been very little work done on the embryology of the Wall-eyed Pile for the literature contains only one article that is even closely related to this problem. In 1890 Reighard made a general study of the development of the Wall-eyed Pike from the time of fertilization to the fully grown adult. He did not, however, make any detailed observations on the morphological development which took place on the first day after hatching. The Wall-eyed Pike embryos used in this study were obtained from the Delafield Hatchery, Wisconsin. The material was killed in Bouin's fixative and then stored in 50% ethyl alcohol. The material in this study was taken from embryos which had been hatched for approximately seventeen hours.
