“…However, the trade-off among different species and fisheries is a crucial concern in multispecies management (Rindorf et al 2013). The multiobjective concept and the Pareto frontier, which presents a set of optimal solutions in which no objective can be improved without making other objective worse off, have been used in several fisheries studies to show the trade-off among different objectives (Dujardin and Chades 2018;Enrıquez-Andrade and Vaca-Rodrıǵuez 2004;Vaca-Rodríguez and Enríquez-Andrade 2006). By applying the multiobjective optimization, we can analyze the trade-off between salmon and herring fisheries under different multispecies management contexts with designed scenarios.…”

Multispecies bio-economic models are useful tools to give insights into ecosystem thinking and ecosystem-based management. This paper developed an age-structured multispecies bio-economic model that includes the food web relations of the grey seal, salmon, and herring, along with salmon and herring fisheries in the Baltic Sea. The results show that the increasing seal population influences salmon fisheries and stock, but the impacts on the harvest are stronger than on the stock if the targeted management policies are obeyed. If seal population growth and a low herring stock occur simultaneously, the salmon harvest could face a serious threat. In addition, scenarios of the multispecies management approach in this paper reveal a benefit that our model can evaluate the performance of different fisheries with identical or different management strategies simultaneously. The results show the most profitable scenario is that both fisheries pursuit aggregated profits and reveal a trade-off between herring fisheries and salmon fisheries. Our model indicates that the herring harvest level and the approaches to managing herring fisheries can influence the performance of salmon fisheries. The study also demonstrates a way to develop a multispecies bio-economic model that includes both migratory fish and mammalian predators.

“…The weight vectors used are to a certain extent adapted to the actual preferences of the current situation. It would therefore be very useful to have knowledge of these preferences (Nijkamp et al 1990, Munda et al 1994, Enríquez-Andrade and Vaca-Rodríguez 2004, in order to de cuadrantes clasificados como pésimos, muy malos y malos en conjunto (aprox. 5%), habla de que, en general, hay más posibilidades de que cualquier cuadrante trimestral, siempre y cuando no sea conflictivo, resulte satisfactorio para la mayoría de los encargados de la toma de decisiones.…”

In this study, we analyse effort optimisation in common rights-based joint-stock artisanal fisheries when several objectives are pursued by the authorities and the fleets are heterogeneous. The purpose is to discuss policy options available to the authorities and their implications in terms of trade-offs between goals. We apply a multi-objective programming model to the sardine and anchovy artisanal fisheries in central southern Chile. The results suggest that the regulatory system generates inefficient solutions for profit and employment maximisation goals. Moreover, the fleet structure of the artisanal organisations is central for the outcomes obtained by different policy simulations. To improve effort assignment, the authorities should seek to increase flexibility in the system.
