Reconciling the economic and biological fishery data gathered through the European Data Collection Framework: A new R-tool.

Fishing fleets and targeted stocks are the basis for the design of multiannual management plans at European or Mediterranean levels. Management Strategy Evaluation and bioeconomic modeling need data at a specific level of resolution in terms of time, area and type of fishing activity for analyzing measures for management procedures using simulations. Within the Data Collection Framework, data are to be aggregated at different levels, e.g.: fleet segment and métier, the former linked to the predominant gear and the size of the vessel and the latter to the activity itself. Fishing costs are collected by fleet segment, effort and landings by fleet segment and métier. Bioeconomic modeling for management purposes requires data at the same resolution. The aim of this paper is to describe a methodology, implemented in SECFISH R package, to disaggregate variable cost data from the fleet segment to the métier level. The presented tool allows to determine the correlation between the variable costs of a vessel and its activities to estimate costs at the activity level (e.g. métiers). The tool is applied to selected Italian fleet segments characterized by a variety of métiers and high dynamicity.

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.
