Behavioural economics in fisheries: A systematic review protocol.

BACKGROUND: The field of behavioural economics holds several opportunities for integrated fisheries management and conservation and can help researchers and managers alike understand fisher behaviour and decision-making. As the study of the cognitive biases that influence decision-making processes, behavioural economics differentiates itself from the classical field of economics in that it does not assume strictly rational behaviour of its agents, but rather looks for all mechanisms that influence behaviour. This field offers potential applications for fisheries management, for example in relation to behavioural change, but such applications require evidence of these mechanisms applied in a fisheries context. Thus, we have developed a systematic literature review protocol focusing on the primary question: "Which behavioural economics mechanisms influence fisher behaviour?" The aim is to provide a comprehensive overview of these different mechanisms and how they have been applied in the study of fisher behaviour. METHODS AND EXPECTED OUTPUTS: The review protocol was developed in close collaboration with the International Council for the Exploration of the Sea (ICES) Working Group on Maritime Systems (WGMARS). WGMARS members were therefore considered the key stakeholders for this study, and were consulted to develop a suitable systematic review question and methodology. Three academic databases will be searched using a customized Boolean keyword search string. Research articles deemed eligible for inclusion in the systematic review are those that studied the influence of behavioural-economics mechanisms on the behaviour of marine fishers in any location, and at any scale. Insights from this literature will be collated in order to provide an overview of the relevant behavioural-economics mechanisms and actions, how effective these mechanisms are and at what scale, geographic region and in which fisheries sector they have been applied. Any fisheries management implications identified by the studies under review will also be outlined. Finally, it will be recorded whether or not ethical considerations were made in the reviewed literature, so that in the discussion it will be possible to reflect on the ethics of conducting behavioural-economics research and policy actions in a fisheries context.

Efficiency vs resilience: The rise and fall of the German brown shrimp fishery in times of COVID 19.

In times of world crisis such as climate change and the COVID pandemic much has been said about the need for resilience. However, in scenarios of less concern about crisis the leading paradigm is often that of efficiency. The current study shows how efficiency might have got on the way of achieving the necessary resilience to face the COVID 19. With the example of the German brown shrimp fishery in the North Sea the interaction between those two paradigms - efficiency and resilience - is shown in the context of the COVID 19 pandemic. For instance, the quest of efficiency for rationalisation may reduce the resources available to set aside buffers to resist shocks, and the standardisation key to efficiency may also hinder more diversity and hence open innovation for solutions to the crisis, all characteristics of resilient organisations. By making use of a literature review including peer reviewed, grey literature and web media as well as of interviews with experts and quantitative data the value chain of the German brown shrimp fishery is analysed under the conceptual framework of organisational resilience. Results: show that, despite being more oriented towards efficiency, the German fleets does not show particularly good results in selected efficiency indicators. Additionally, key stages of the value chain as processing and commercialisation together with the investment strategy fail to present some commonly accepted components of resilient organisations, such as redundancy, flexibility, adaptability, diversity, prudence and embeddedness. Despite developments in the direction of sustainability with the MSC certification, the German fleet should pay attention to its capacity to face disturbances, which should be supported by a more long-term, targeted, resilience-oriented policy support.
