 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, i.e. 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 (Ricker, 1975). Abbreviated as z
