Percentage of male hard clams/developmental stage (qualitative criteria). Analysis of the female developing stage requires consideration of both qualita- tive and quantitative data. Developmental stages in Henlopen and Delaware Bay females indicated a similar pattern. However, although both groups were in the developing stage, the mechanism was different. Henlopen clams regenerated large numbers of ovocytes rapidly, which slowly increased in size during the winter and spring. Delaware Bay clams developed slowly in both size and number of ova for a long period of time. Ripe individuals appeared as early as December (10% of individuals). From January through April, there was a slight increase in the percentage of ripe individuals per month. Between April and May, rapid ovogenic activity produced large numbers of ripe individuals. June was characterized by the greatest percentage of ripe individuals and the onset of spawning activity for both males and 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 Marine Biological Laboratory (Woods Hole, Mass. ); Marine Biological Laboratory (Woods Hole, Mass. ).
