“…Pots generate low discard rates compared to many other gear types (Petetta et al, 2021). Developing fish pots would help fishers to cope with new gear constraints due to the multiplication of maritime usages such as wind farms (Yates et al, 2015;Stelzenmüller et al, 2021) and marine protected areas (Cadiou et al, 2009).…”

The French fishing industry is becoming increasingly environmentally aware and likely to adopt more sustainable fishing gears. As a result, fishers are showing a growing interest in sustainable fish pots. This experiment aimed to develop a fish pot concept specifically based on target species behavior in French coastal waters. First, the consultation led with fishers indicated the black seabream as the main species of interest. Then, the pot’s characteristics were defined to comply with fishing regulations. The conception process of the pot was led step-by-step by gradually testing a pot design appropriated to black seabream’s natural behavior. The approach and feeding behaviors of black seabream were described using underwater video combined to an ethogram. The experiment led to a prototype of fish pot, which provide fishers with an innovative fishing gear.

“…Comparing regions with catchments in the same period, Bennet (1974) observed ~40* more females in august (Devon, UK). Stelzenmüller et al (2021), on the contrary, encountered 4.8 more males (in June and August, in the German Bight). Apparently there is a strong regional aspect to behaviour and catchability.…”

“…had CPUEs ranging from 0.28 to 2.81, depending on pot type and soaking time, at Yorkshire, UK.Bell et al (2003) calculated an CPUE of 2.74 per tide (one low and high water period) which is roughly 5.5 brown crabs per pot per day at the Race Bank, north Norfolk also in the months August, September. Spencer (2013) had an average CPUE of 1.79 per tide which is roughly 3-4 crabs per pot per day (4-22 brown crabs per pot) near Seaton Sluice (UK).Wolf et al (2006) found various CPUEs ranging from 3.6 to 13.4 at various locations in Norway with habitats ranging from exposed (ocean) to sheltered (fjords and protected grounds leeward of large islands).Öndes et al (2019) calculated an average CPUE of 7 to 8 brown crabs per pot, depending on type of pot, type of bait and boat, moment of the year (Isle of Man, northern Irish Sea) Stelzenmüller et al (2021). found an average CPUE of 14.5 brown crabs (June and August) in transects an OWF located near the island of Helgoland (German Bight, the better area for brown crab,…”

“…Our second literature review round meant to help qualify and further quantify risks and benefits while also considering potential conflict resolution strategies (Figure 1). Literature targeted included: 1) scientific literature on co-location (Mehdi et al, 2017;Mehdi et al, 2018;Degraer et al, 2020;Stelzenmüller et al, 2021), risk assessments (for shipping: collision risk with vessels (Moulas et al, 2017), effects of OWFs on the shipping activity (Rawson and Rogers, 2015)), effects of OWFs on the marine environment (OWF as a protected area (Ashley et al, 2014)), fishing activity (Andrew Gill et al, 2020); 2) governmental/industry reports and guidelines on the interaction between OWFs and the analyzed activities: military (Office of the Director of Defense Research andEngineering, 2006), shipping (Maritime &Coastguard Agency, 2006), nature protected areas (Copping and Hemery, 2020) (Netherlands (Hermans et al, 2020), England (Harley et al, 2009)); 3) OWF project reports and environmental impact assessments: military (Ørsted, 2018), nature protected areas (environmental impact assessments for OWFs in the study area: Horns Rev (NL), Borselle (NL), Walney(UK), etc.). This allowed us to summarize conflict resolution and management strategies and practices for solving, minimizing or mitigating negative effects, in the interaction with OWFs.…”

Growing EU energy ambitions in the North Sea region are urging for an accelerated deployment of large-scale renewable energy (RE) infrastructure, with offshore wind farms (OWF) playing an essential role. However, implementing the current EU targets is limited by the competing spatial claims between existing sea uses and OWFs and uncertainties related to potential risks of interaction, creating important barriers to a swift roll-out of RE infrastructure. In tackling this issue, we are proposing a transparent and spatially explicit multi-criteria analysis tool to quantify and qualify the main risks and opportunities resulting from the interaction between OWFs and four other seas user groups (shipping, marine protected areas, fisheries and military activities). The multi-criteria analysis framework is accounting for sectoral activity specific risks of interaction with OWFs, classified through the respective available conflict resolution options, which allows for the quantification of the average conflict score (ACS) between the selected activities and OWFs. Using the resulting ACS and the geo-location of areas of interaction, we map areas of high and low conflict with OWFs and indicate management options for solving, minimizing or compensating the conflicts. Our results indicate that conflict resolution strategies in marine mammal’s habitats present the highest potential for unlocking medium value OWF sites both for the Dutch case (15.8 – 28 GWs) and English case (15.94-28.3 GWs), followed by pelagic fisheries in the Dutch case (15-26.9 GWs) and passenger/cargo routes in the English case (10.9-19.4 GWs). The strategic planning of increasingly larger and more complex OWF projects will require a better understanding not only of the level of conflict with the other sea users in relation to the valuable OWF sites, but also potential management options to solve, minimize or compensate those conflicts. As an example, accessing 6.8-12.3 GWs in high value OWF sites in the Dutch EEZ will require the relocating of military flying areas with forbidden access, while technical solutions such as “fill-in-the-gap” or relocation of lower airspace radars could unlock 10.25-18.16 GWs in the English EEZ. By avoiding high risk areas and prioritizing areas of low conflict, the bottlenecks, negative effects and inefficiencies related to space management options can be minimized, while synergies and positive effects of OWF deployment can be timely captured.
