instantaneous rate of recruitment
 instantaneous rate of recruitment

Number of
fish that grow to catchable size per short interval of time, divided by the number of catchable
fish already present at that time. Usually given on a yearly basis: that is, the figure just described is divided by the fraction of a year represented by the "short interval" in question. This concept is used principally when the size of the vulnerable
stock is not changing or is changing only slowly, since among fishes
recruitment is not usually associated with
stock size in the direct way in which
mortality and growth are.
