Mean size at age in [fish] stock assessments is generally assumed constant through time and is typically characterized by estimating a somatic growth curve. However, assuming time-invariant somatic growth may be overly simplistic because growth can vary due to temporal variability in a number of factors such as temperature ..., food availability ..., salinity ..., and light ... Estimating time-varying growth curves from observed size at age is difficult, as changes can also be due to other factors, such as changes in selectivity or length-weight relationships.
