Optimal Harvesting Considering Biological and Economic Objectives

This study was the precursor to the more detailed study done almost a decade later and described on the Escapement Goal Analysis page. This study stemmed from a 2004 escapement goal review that suggested larger escapement goals would lead to greater catches (and value of the catch).

 

The analysis showed that average catch is maximized by a fixed escapement goal but that annual revenue would be maximized at allowing harvesting to escapements below levels that maximize catch. The analysis also concluded a more detailed, daily model of the fish and fishery would better capture the trade offs among escapement policies and better quantify the economic benefits among alternatives.
