The implications of a transition from tickler chain beam trawl to electric pulse trawl on the sustainability and ecosystem effects of the fishery for North Sea sole: an impact assessment

“…The selected species and species groups represent different ecosystem components and habitats that are relevant with regard to the management under the Common Fisheries Policy (CFP), the Landing obligation (LO), the Marine Strategy Framework Directive (MSFD) and the Birds and Habitat Directive (BHD). The species are also related to specific concerns that have been raised about possible adverse effects of pulse fishing (Kraan et al, 2015;Quirijns et al, 2018).…”

“…Concerns exist regarding possible negative impacts of the electrical stimulus on benthic invertebrates (ICES, 2018;Quirijns et al, 2018). Invertebrates are exposed to high electric field strengths between the electrodes arrays (de Haan et al, 2016;de Haan and Burggraaf, 2018).…”

Direct mortality among demersal fish and benthic organisms in the wake of pulse trawling

“…Pulse fishery involves the use of electrical pulses to startle target species from the seabed and make them available for the capture. Various stakeholders expressed their concerns about the impacts of pulse fisheries, see Quirijns et al (2018) for an inventory. A major concern is the direct effect of a passing pulse trawl on benthic organisms.…”

A Transdisciplinary Approach Towards Studying Direct Mortality Among Demersal Fish and Benthic Invertebrates in the Wake of Pulse Trawling

“…The increase in pulse licenses was heavily criticized (Haasnoot et al, 2016;Le Manach et al, 2019;Kraan et al, 2020) and fueled the already existing concerns about the adverse effects on marine life and the consequences of the more efficient gear for other fishers (Stokstad, 2018;Quirijns et al, 2018). Pulse trawling was thought to electrocute marine life (Bloom, 2018).…”
