The influence of parameter bias on YPR
and SPR models has been investigated since the 1950s (e.g., Beverton and Holt, 1957; Goodyear, 1993; Mace, 1994), but the effects of precision uncertainty have seldom been addressed.

Young People in Recovery (YPR
) is a national movement of young people in long-term recovery, with a vision that states "we envision a world where we don't have to bury any more of our friends due to drugs and alcohol." The movement is united at all levels to empower young people to find and sustain recovery.
The Beverton and Holt (1966) yield-per-recruit (YPR
) model modified by Pauly and Soriano (1986) was used to estimate the sizes at maximum yield per recruit ([L.sub.max]) and to predict the effects of increasing the mean size at first capture ([L.sub.50]) to the mean size at first sexual maturity ([L.sub.mat]) and that at which yield per recruit would be maximized ([L.sub.max]).
Equilibrium yield per recruit (YPR
) was estimated by the method of Ricker (1975), which divides the exploited life span into phases of constant mortality and growth rates; total YPR
is obtained by summing yield across phases.
