    It depends on many factors. There is a lot of math behind it actually. The Yield-per-recruit Analyses is used for just such a measure.

    we may here visualize recruits as fully metamorphosed young fish, whose growth is described adequately by the VBGF, and whose instantaneous rate of natural mortality is assumed similar to that of the adults. Such recruits have an average age tr, an average length Lr and an average weight Wr. Upon reaching age tr, the recruits may be caught immediately, in which case the mean age at first capture tc is equal to the age at recruitment (tc = tr). Alternatively, the recruits may be caught at a more advanced age (and correspondingly larger sizes, Lc and Wc)
