ANCHOVIA MITCHILI-I. spawning.âThe eggs of Anchovia mitchilli were present in the plankton when work was begun on June 9, and were collected in the tow net nearly every day after that date until August 23, when the work was discontinued. During the second and third weeks in June the eggs of this species were not abundant, though they were sufficiently numer- ous to be readily obtained for study. Toward the close of June they became numerous, and they were much more abundant in the plankton during July and August than the eggs of any other fishes spawning during these months. The height of the spawning season is probably reached during July. As already indicated, this species, like Bairdiella chrysura, spawns regularly in the early evening, probably before 8 o'clock p. m. On a few occasions newly spawned eggs were collected before 6 o'clock p. m. Usually, however, no newly spawned eggs were 19371°âvol 33â 2.
