Hypothetical populations of aquatic insects were periodically sampled, using a computer model, to estimate production by the instantaneous‐growth, removal‐summation, and Hynes/Hamilton methods. These estimates were compared with the production values calculated from the daily growth of all individuals in the populations. The removal‐summation method yielded the most accurate estimates for a variety of growth curves and sampling regimes and appeared to be the least sensitive to violations of the growth assumptions of the method.
