“…For example, ocean-going vessels cannot operate within fjords without special permission. For pelagic species, the fishers are most active from October to December when herring overwinter near the coast and in Northern fjords and then again January to March during the spawning migration and spawning for the herring, while mackerel are mainly targeted during their wintering cycle in southern Norway from September to December when the market prices are highest, although there is inter-annual variability (Varpe et al, 2005;Nøttestad et al, 2016;Ølmheim, 2021;Reite et al, 2021). The following sections describe the DSS tool according to its data sources, modelbased inputs and the user interface (Figure 1).…”

Frontiers is more than just an open access publisher of scholarly articles: it is a pioneering approach to the world of academia, radically improving the way scholarly research is managed. The grand vision of Frontiers is a world where all people have an equal opportunity to seek, share and generate knowledge. Frontiers provides immediate and permanent online open access to all its publications, but this alone is not enough to realize our grand goals. Frontiers journal seriesThe Frontiers journal series is a multi-tier and interdisciplinary set of openaccess, online journals, promising a paradigm shift from the current review, selection and dissemination processes in academic publishing. All Frontiers journals are driven by researchers for researchers; therefore, they constitute a service to the scholarly community. At the same time, the Frontiers journal series operates on a revolutionary invention, the tiered publishing system, initially addressing specific communities of scholars, and gradually climbing up to broader public understanding, thus serving the interests of the lay society, too. Dedication to qualityEach Frontiers article is a landmark of the highest quality, thanks to genuinely collaborative interactions between authors and review editors, who include some of the world's best academicians. Research must be certified by peers before entering a stream of knowledge that may eventually reach the public -and shape society; therefore, Frontiers only applies the most rigorous and unbiased reviews. Frontiers revolutionizes research publishing by freely delivering the most outstanding research, evaluated with no bias from both the academic and social point of view. By applying the most advanced information technologies, Frontiers is catapulting scholarly publishing into a new generation. What are Frontiers Research Topics?Frontiers Research Topics are very popular trademarks of the Frontiers journals series: they are collections of at least ten articles, all centered on a particular subject. With their unique mix of varied contributions from Original Research to Review Articles, Frontiers Research Topics unify the most influential researchers, the latest key findings and historical advances in a hot research area.

“…The scales of fishing activity decisions can be separated based on duration into three categories: strategic, tactical and operational decisions. Strategic decisions (weeks to months to years) refers to long-term planning of location and timing offishing based on expectations of both the market and fishing possibilities (Reite et al, 2021). Tactical decisions (hours to days) are decisions about which fishing grounds to visit, the number of grounds to visit and where and when to return to port to land catches (Granado et al, 2021).…”

“…Tactical decisions (hours to days) are decisions about which fishing grounds to visit, the number of grounds to visit and where and when to return to port to land catches (Granado et al, 2021). Long-term tactical decisions may involve, for example, planning of whether to target herring or mackerel based on market prices (Reite et al, 2021). Short-term tactical decisions include motion planning of fishing vessels and controlling position and course of vessels relative to schools of fish (Haugen and Imsland, 2019;Haugen and Kyllingstad, 2021;Kyllingstad et al, 2021).…”

Capturing big fisheries data: Integrating fishers’ knowledge in a web-based decision support tool

et al. 2022

There is increasing interest in utilizing fishers’ knowledge to better understand the marine environment, given the spatial extent and temporal resolution of fishing vessel operations. Furthermore, fishers’ knowledge is part of the best available information needed for sustainable harvesting of stocks, marine spatial planning and large-scale monitoring of fishing activity. However, there are difficulties with integrating such information into advisory processes. Data is often not systematically collected in a structured manner and there are issues around sharing of information within the industry, and between industry and research partners. Decision support systems for fishing planning and routing can integrate relevant information in a systematic way, which both incentivizes vessels to share information beneficial to their operations and capture time sensitive big datasets for marine research. The project Fishguider has been developing such a web-based decision support tool since 2019, together with partners in the Norwegian fishing fleet. The objectives of the project are twofold: 1) To provide a tool which provides relevant model and observation data to skippers, thus supporting sustainable fishing activity. 2) To foster bidirectional information flow between research and fishing activity by transfer of salient knowledge (both experiential and data-driven), thereby supporting knowledge creation for research and advisory processes. Here we provide a conceptual framework of the tool, along with current status and developments, while outlining specific challenges faced. We also present experiential input from fishers’ regarding what they consider important sources of information when actively fishing, and how this has guided the development of the tool. We also explore potential benefits of utilizing such experiential knowledge generally. Moreover, we detail how such collaborations between industry and research may rapidly produce extensive, structured datasets for research and input into management of stocks. Ultimately, we suggest that such decision support services will motivate fishing vessels to collect and share data, while the available data will foster increased research, improving the decision support tool itself and consequently knowledge of the oceans, its fish stocks and fishing activities.

“…Decisions can be categorized based on the time scales: strategic (weeks to months to years), tactical (hours to days) and operational decisions (near real-time). The type of support provided will depend on the category of decisions being made (Reite et al, 2021b). Routing and scheduling in shipping industry has been used to reduce fuel consumption through optimization of speed and heading (Bal Bes¸ikci et al, 2016;Granado et al, 2021).…”

Estimation of fish catch potential using assimilation of synthetic measurements with an individual-based model

A large fraction of costs in wild fisheries are fuel related, and while much of the costs are related to gear used and stock targeted, search for fishing grounds also contributes to fuel costs. Lack of knowledge on the spatial abundance of stocks during the fishing season is a limiting factor for fishing vessels when searching for suitable fishing grounds, and with better planning and routing, costs can be reduced. Strategic and tactical decision-making can be improved through operational decision support tools informed by real-time data and knowledge generated from research. In this article, we present a model-based estimation approach for predicting catch potential of ocean areas. An individual-based model of herring migrations is combined with an estimation approach known as Data Assimilation, which corrects model states using incoming data sources. The data used to correct the model are synthetic measurements generated from neural network output. Input to the neural network was vessel activity data of over 100 fishing vessels from 2015-2018, targeting mainly herring. The output is the predicted normalized density of herring in discrete grid cells. Model predictions are improved through assimilation of synthetic measurements with model states. Characterizing patterns from model output provides novel information on catch potential which can inform fishing activity.
