A new era for science-industry research collaboration – a view towards the future

“…Many challenges to effective fisheries management relate to the constraints on government-run sampling efforts that are often seasonspecific or otherwise limited in both duration and temporal coverage (Thorson, 2019;Bleeker et al, 2021;Gonzalez et al, 2021), constrained or influenced by gear performance (i.e., selectivity, Cadrin et al, 2016;Kotwicki et al, 2017), or otherwise unable to access all viable or relevant habitats (i.e., availability, Punt et al, 2014;Baker et al, 2019a). Many of the data needs identified in our discussions reflected these recognized limitations to scientific surveys and sampling.…”

“…These benefits have been demonstrated across multiple ecosystems and management frameworks. Direct benefits include cost-efficient data collection, enhanced temporal and spatial coverage, increased quantity and quality of the available data, and improved knowledge for fisheries management (Karp et al, 2001;Wendt and Starr, 2009;Lordan et al, 2011;Kraan et al, 2013;Stephenson et al, 2016;Mangi et al, 2018;Bleeker et al, 2021). SIRC also integrates industry knowledge in science and management (Neis et al, 1999;Kaplan and McCay, 2004) and improves the relevance of directed research, ensuring it addresses important pressing fisheries management issues (e.g., stock status, selectivity, gear technology, habitat closures; Johnson and Van Densen, 2007;Stephenson et al, 2016;Baker and Smith, 2018).…”

A will-o’-the wisp? On the utility of voluntary contributions of data and knowledge from the fishing industry to marine science

“…Voluntary fishing industry data, including from fish processors, may exceed that collected by government or thirdparty sampling schemes in amount and distribution (Mackinson et al, under review;Power et al, 2007;Rochette et al, 2018;Dunn, 2020;Kenyon et al, 2022). Such sampling can go beyond providing data on catches, and can contribute to surveying parts of the stock not targeted in the same way that fisheriesindependent scientific surveys do (Gerlotto et al, 2012;Schram et al, 2021). In addition to fish stock assessments, industry data have also contributed to an improved knowledge base or validation of by-catch data regarding seabirds, marine mammals and Endangered, Threatened and Protected species (Bjørkan, 2011;Fangel et al, 2015;Fry et al, 2018;Moan et al, 2020).…”

“…To overcome concerns about consistent, long-term availability of voluntary industry data, most long-term SIRC initiatives rely on an assortment of remuneration options, such as remuneration for haul specific logbook data or discard samples (Kraan et al, 2013;Jones et al, 2022); payment of net income differences with comparable vessels not involved in research (Schram et al, 2021); additional quota allocations (Kindt-Larsen et al, 2011;Van Helmond et al, 2016); or payment for ship and crew hire (Ressler et al, 2009;Gallaudet, 2021;Hoff et al, 2021). In this context, it is important to note that concerns about long-term availability of data and information are not exclusive to industry contributions.…”

“…They have also implemented self-sampling data collection schemes to clarify biological questions on the duration of the spawning period of mackerel and the linkage between populations in the western area and the North Sea (Pastoors, 2021;Kenyon et al, 2022;Mackinson, 2022). The Dutch demersal industry initiated a dedicated survey for North Sea turbot and brill in response to ICES advice that highlights the need for such a survey (ICES, 2019b;Schram et al, 2021). Other motivations for funding voluntary data collection include, for example, requirements to provide evidence in support of sustainability certification schemes or providing information for developing fisheries management plans, including harvest control rules and protection of spawning and nursery areas (Steenbergen et al, 2017;Holm et al, 2020a).…”
