In particular, the rate of recruitment was remarkably high from the mid 1970s to the early 1980s. Variation in the recruitment rate R/S, may reflect variation in early survival of cod, or variation in the quantity or quality of eggs produced by a unit of spawning stock biomass. This paper tests two predictions related to effects of spawner characteristics on recruitment rate. First, a positive correlation between recruitment rate and measures of the age of spawners (i.e., mean age, proportion of older fish, age diversity) is predicted. The second prediction is of a positive correlation between recruitment rate and measures of the mean size and condition of spawners.
