A class of growth models incorporating time‐dependent factors and stochastic perturbations are introduced. The proposed model includes the existing growth models used in fisheries as special cases. Particular attention is given to growth of a population (in average weight or length) from which observations are taken randomly each time and the analysis of tag‐recapture data. Two real data sets are used for illustration: (a) to estimate the seasonal effect and population density effect on growth of farmed prawn ( Penaeus monodon ) from weight data and (b) to assess the effect of tagging on growth of barramundi ( Lates calcarifer ).
