Equations for age-specific and interval models of individual growth used in the study.

Parameters are t–age (in years or days), PLt−size at age t, k–characteristic growth rate coefficient, A∞−asymptotic size, b–proportion of growth remaining toward A∞ at t0, e is the base of the natural logarithms, PLC is the size at t1, PLR is the size at t2, and Δt is the time interval (t2 –t1).
