Recent research on global fisheries has reconfirmed a 2006 study that suggested global fisheries would collapse by 2048 if fisheries were not better managed and trends reversed. While many researchers have endorsed rights-based fishery management as a key ingredient for successful management and rebuilding fisheries, in practice the results are mixed and success varies by geographic region. Rights-based approaches such as individual transferable quota (ITQ) provide a necessary help to the important task of rebuilding fisheries, but we assert that they are sometimes less effective due to the human component of the system. Specifically, we examine the issue of setting an appropriate total allowable catch (TAC) in Individual Transferable Quota (ITQ) systems. ITQ are designed on the premise that economic ownership is sufficient incentive to entice fishers to be stewards of the resource. However, an excessive short-term orientation and an affective risk response by fishers can overwhelm feelings of ownership. In such cases, fishers and fishing communities can exert sufficient pressure on TAC setting and reduce the effectiveness of ITQ fisheries toward rebuilding fish stocks. Based on our analysis that draws on cognitive psychology, short-termism, and affective risk, we suggest heightened and wider democratic involvement by stakeholders in co-managed ITQ fisheries along with potential pilot tests of government-assisted financial transfers to help in transitioning ITQ fisheries to sustainable states.

Ensuring productive and sustainable fisheries involves understanding the complex interactions between biology, environment, politics, management and governance. Fisheries are faced with a range of challenges, and without robust and careful management in place, levels of anthropogenic disturbance on ecosystems and fisheries are likely to have a continuous negative impact on biodiversity and fish stocks worldwide. Fisheries management agencies, therefore, need to be both efficient and effective in working towards long-term sustainable ecosystems and fisheries, while also being resilient to political and socioeconomic pressures. Marine governance, i.e., the processes of developing and implementing decisions over fisheries, often has to account for socioeconomic issues (such as unemployment and business developments) when they attract political attention and resources. This paper addresses the challenges of (1) identifying the main issues in attempting to ensure the sustainability of fisheries, and (2) how to bridge the gap between scientific knowledge and governance of marine systems. Utilising data gained from a survey of marine experts from 34 nations, we found that the main challenges perceived by fisheries experts were overfishing, habitat destruction, climate change and a lack of political will. Measures suggested to address these challenges did not demand any radical change, but included extant approaches, including ecosystem-based fisheries management with particular attention to closures, gear restrictions, use of individual transferable quotas (ITQs) and improved compliance, monitoring and control.

This paper develops a system dynamics model of Individual Transferable Quota (ITQ) systems in order to differentiate ITQ from total allowable catch (TAC) effects and to identify areas where policy changes and management improvement may be most effective. ITQ systems provide incentives for long-term stewardship but when fisheries are managed “at the edge,” the incentives are inadequate for stock rebuilding. The free-market design of ITQ systems means that fishermen may be in conflict with the long-run, public sustainability goals of fishery management. An adaptive control scheme with a contingent public/private transfer payment is proposed to improve long-term results for both the local community and the general public. Full article
