ABSTRACT
In the March 1964 issue of this journal, Ralph Turvey states that “if the optimum optimorum is to be reached, … then (fishery) regulation must extend not only to the scale but also to the mode of operation” [1, p. 64]. He recommends both a toll or charge per pound of fish caught (scale regulation) and the imposition of a legal minimum mesh size (mode regulation) in order to achieve a Pareto-optimum.
