“…With this method, tickler chains are being replaced by electrodes to electrically stimulate flatfish out of the sediment. Reduced fuel consumption (up to 50%) from lower towing speeds/decreased drag through the seafloor (van Marlen et al, 2014), reductions and increased survivorship of discards (van Marlen et al, 2014;Batsleer et al, 2016;Reijden et al, 2017) provided evidence for pulse fishing as an environmentally friendly alternative to traditional tickler chain beam trawling. Its popularity amongst the Dutch fishing fleet (Haasnoot et al, 2016), however, was met with international criticism due to increased competition between fishermen (Sys et al, 2016) and ecological concerns over animal welfare (de Haan et al, 2016;Soetaert et al, 2016a;Soetaert et al, 2016b).…”

Research on the environmental impacts of bottom fishing gears has focused mainly on structural characteristics of benthic habitats such as faunal composition and the physical features of the seafloor. This study focuses more on functional characteristics by addressing the biogeochemical consequences associated with tickler chain beam trawl and electric PulseWing trawl gears. In June 2017, professional fishermen trawled experimental transects with both types of gears in the Frisian Front area of the North Sea. Box core sediment samples and in situ landers were used to evaluate biogeochemical fluxes and sediment characteristics in untrawled and trawled areas (samples taken 3.5–70 h after fishing). A reduction of sedimentary chlorophyll a was observed, which was larger following tickler chain (83%) compared to PulseWing trawling (43%). This displacement of surface material caused significant decreases in the sediment oxygen consumption in tickler chain (41%) and PulseWing trawled samples (33%) along with a deeper penetration of oxygen in the sediment (tickler chain: 3.78 mm, PulseWing: 3.17 mm) compared to untrawled areas (2.27 mm). Our research implies that bottom trawl disturbance can lead to immediate declines in benthic community metabolism, with tickler chain trawling exhibiting more prominent alterations than PulseWing trawling on benthic biogeochemical processes.

“…Er bestaat echter ook een kans dat de maatregel niet goed wordt geïmplementeerd en dus niet tot minder bijvangst zal leiden (dwz. dat de visserij gewoon zal doorgaan en dat de vangst boven de quota komt en de minst waardevolle maten overboord gaan) (Batsleer et al, 2016). Een ander mogelijk gevolg is een toename van visserijsterfte voor niet-doelsoorten, zoals bijvoorbeeld voor schar (van Helmond & Steins, 2016).…”

“…The arguments above imply that as pointed out in Hatcher (2014) discarding has an economic rationale and a likely reaction from the fishermen can be expected (Batsleer et al, 2016;Simons et al, 2015). This rationality implies that banning discards will create economic consequences.…”

“…As has been shown in the previous sections these incentives come in the form of reducing the choke effect and in the form of the economic damage caused by the uplift redistributive effect. Furthermore, as it can be seen in Batsleer et al (2016) landing obligation will force fleets to react.…”

The bad, the good and the very good of the landing obligation implementation in the Bay of Biscay: A case study of Basque trawlers

Landing obligation (LO) has become a core element on the Common Fisheries Policy (CFP). In this work a bioeconomic simulation tool is used to anticipate the effects of LO in a particular fleet that by its nature is likely to be highly affected by its implementation. These effects are measured in terms of biologic, economic and fleet indicators.Results show how LO has a negative short term effect in the economic performance of the fleet (the bad). That the exemption and flexibilities foreseen in the CFP alleviate, in the short term, the effects of the choke species and the redistribution effects created (the good). Furthermore, results show that there are private incentives to improve the selectivity and to reduce the discard levels of the fleets. It is concluded how a breeding ground for a more sustainable and productive system is created (very good).
