Table 4

Summary statistics for Jones Length Cohort Analysis (LCA) data series and model derived estimates of recruits R (millions of individuals). Values obtained for the full 1995–2020 time series (26 yr) and for shorter time series lengths (15 to 25 yr) for Micropogonias megalops in NGC. Mean, minimum and maximum recruitment values across the different time series are shown.
