Rebuilding outcomes were found to vary considerably with the type of technology employed (as proxied by changing the catchability coefficient) and the presence of cost and biological interactions. In particular, consideration of biological interactions drastically increased the ambiguity of the outcome, and different combinations of interactions and technologies were found to further deplete the stock rather than rebuild it. They conclude that the failure to consider such interdependencies may negatively affect rebuilding efforts. An age-structured dynamic bioeconomic model was developed to account for the different cohorts. Net benefits were calculated using price and variable cost functions that were inversely proportional to landings and spawning biomass, respectively.
