Abstract
The assessment of fish production rates as a function of stock size is central to fisheries management, and this assessment obviously requires observations from a range of stock sizes. When stock size variation is due mainly to natural, random disturbances that are treated as “natural experiments”, the resulting sample may give a very distorted (biased) picture of the average production relationship. The bias will be especially bad when the natural disturbances occur in autocorrelated sequences over time. These results suggest that there is no safe substitute for deliberate, controlled experimentation with stock size.
