Larvae from each spawn can be considered a cohort and would be responsible for the occurrence of multiple modes in the length frequency histograms. The shift in median bl for YOY herring from month to month cannot always be interpreted as growth, such as from April to May 1986, due to the appearance of different cohorts in the sampling area. Most YOY herring leave the bay by mid-summer, and, based on the large number of herring collected, the sampling location appears to be along the emigration route. An approximation of average growth can be obtained from examining the frequency distribution of the peak farthest left in the histograms during June of each year (Figure 4). This most likely represents the cohort from the last major spawn each year which occurred from early February to mid-March. Thus, herring may grow to 50-60 mm bl in 3 to 4 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 California.
