Life-history studies showed croak- er and spot spawning during the middle of the period and razorbelly spawning near the latter part of the period. Spot were spent by the last weeks of December, but a few croak- er were still gravid. The average number of species in October was 15, 19 for November, and 15 for Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original United States.
