The KB WOT Fisheries programme is established to maintain and develop the expertise needed to carry out the statutory obligations of the Netherlands in fisheries monitoring and advice. It is also a flexible program which responds to changes over time in WOT requirements, fisheries management and policy needs. While maintaining the core expertise and flexibility, the KB WOT programme also strives to be innovative and participate in the development of fisheries science. The programme operates within the context of the Common Fisheries Policy (CFP), the EU Marine Strategy Framework Directive (MSFD) and the EU Maritime Policy. The KB WOT fisheries programme is established annually and positioned around a number of themes. In 2015 14 projects were originally awarded. However, one project could not meet all the original objectives and with the remaining budget a 15th project was started on the tool development for fish ageing and maturity staging. These 15 projects were successfully completed. The programme focused on the research into the impact of fisheries on the seafloor, development of tools for electronic monitoring, data storage and dissemination and method development for assessment of marine resources. As always the core element of the KB WOT Fisheries was maintaining and developing key expertise for the WOT programme. A large part of the budget was therefore used for projects that standardise fish ageing, provide quality control of discard, ichthyoplankton and shellfish monitoring and development of fisheries acoustics techniques and expertise. These topics are vital for the quality of fish stock assessments and management. Of the 15 projects funded in 2015, seven were carried out in collaboration with institutes outside the Netherlands. As resources and expertise from these other countries contribute to the KB WOT Fisheries programme, these collaborations provided a large amount of added value to the programme. Another large part of the KB WOT resources is specifically dedicated to international collaboration and exchange of science. This ensures that Wageningen Marine Research researchers remain at the centre of scientific developments and international fisheries research. The programme was also very productive in terms of publications, presentations and developing new methods or tools for fisheries research. Over 15 international presentations were given at meetings, workshops and symposia, and 22 international and national reports written. 8 new methods or models were developed, 3 peer reviewed publications published and 5 scientific publications prepared.

Fishing companies are faced with decreasing profitability and increasing competition. These companies can try to gain a competitive advantage by differentiating their products, e.g. by marketing new product attributes that consumers are interested in such as attributes relating to sustainability. Although consumers could be considerably interested in social sustainability of fish, this sustainability dimension has received little research interest so far. The main objective of this thesis is to understand social sustainability of capture fisheries. Social sustainability can be understood by applying the framework for social sustainability assessment, which consists of stakeholder consultation and issue selection, indicator development and quantification, and interpretation of the results, to the case considered. The case considered in this thesis was capture fisheries in the northeast Atlantic. Stakeholder consultation resulted in the identification of 27 social sustainability issues relevant for capture fisheries in the northeast Atlantic. Overall, social sustainability issues concerning working conditions, employees' job fulfilment and fish welfare were seen as more important than other social sustainability issues. Indicators were defined for the most important social sustainability issues of capture fisheries in the northeast Atlantic. To interpret values for each indicator, rubrics were developed that articulated levels of performance. Application of these indicators and their accompanying rubrics to a Norwegian trawler demonstrated that the indicators and rubrics provide insight into social sustainability at the level of the vessel, which can be used to identify potential room for improvement. To determine whether social sustainability issues can be used for product differentiation, consumer interest in social sustainability issues of whitefish from the northeast Atlantic was studied. Results from a choice modelling survey demonstrated that consumers prefer the issue fish welfare over the issues product quality, worker safety and local employment. Given the lack of overview of the knowledge on fish welfare, the most important social sustainability issue for consumers, the literature on this topic was reviewed to determine how the capture process in capture fisheries affects fish welfare, using the indicators external injuries and mortality. This review showed that scale, skin and fin injuries occur more frequently in trawls, purse seines, gillnets, traps and seines than in hooks, whereas hooking injuries occur in hooks only. Pressure injuries can occur in all gear types when deployed at greater depth. Trawls, purse seines and seines result in higher mortality than gillnets, hooks and traps. Mortality appears to increase with decreasing fish length, and differs across fish species. A greater capture depth and a longer fishing duration were associated with more external injuries and higher mortality, whereas a large change in water temperature, a longer duration of air exposure and a high density in the net were associated with higher mortality only. This thesis shows that application of the framework for social sustainability assessment to capture fisheries in the northeast Atlantic leads to an understanding of social sustainability that fishing companies can use to their advantage. In addition, this thesis shows that fishing companies in the northeast Atlantic need to start paying attention to fish welfare because consumers consider fish welfare the most important social sustainability issue of capture fisheries in the northeast Atlantic.

Pulse fishing and its effects on the marine ecosystem fisheries : an update of the scientific knowledge

This report summarises the knowledge on the effects of pulse trawls used in the North Sea fishery for flatfish and brown shrimp. The report describes the electrical characteristics of the pulse trawl systems currently used (potential difference over electrode pairs, pulse frequency, pulse width, duty cycle and dimensions of the gear). The shrimp pulse applies a low frequency pulse that invokes a startle response (tailflip) in shrimps. The sole pulse applies a higher frequency that invokes a cramp response that immobilise the fish species facilitating the catching process.

In september 2016 heeft een monitoring met staandwantnetten plaatsgevonden op het IJsselmeer en Markermeer. De doelstelling van deze monitoring is een beter beeld te krijgen van de populatie-opbouw van de visbestanden. De reguliere monitoring van vis in het open water (met de actieve vistuigen verhoogde boomkor en electrokor) is met name selectief voor kleine vissen. Grotere vissen worden in deze reguliere monitoring niet goed gevangen. In het staandwantmonitoringsproject is bemonsterd met staandwantnetten met een breed scala aan maaswijdtes. Zodoende kan een breed scala aan vislengtes bemonsterd worden.

Since 1972, the Demersal Fish Survey (DFS) in the Wadden Sea has been carried out with the RV Stern. Within a few years this vessel will be replaced by another vessel as a result of the current ship replacement policy of Rijkswaterstaat Rijksrederij. It is not yet clear which vessel will replace RV Stern. In the search for a new vessel the main question is if fishing over the sides is needed, or if fishing over the stern is possible without a major effect on catch efficiency. Especially in shallow waters, catch efficiency may be affected by fishing over the stern, because of the current created by the ship’s propeller. To be able to continue the use of the long and valuable time-series the shift in vessel should not lead to a different gear efficiency.

In het kader van het vlootvervangingsprogramma van de Rijksrederij is het noodzakelijk om alternatieven aan te reiken voor de bemonsteringen die momenteel door RV Stern worden uitgevoerd. RV Stern zal binnen een aantal jaren niet meer beschikbaar zijn. Dit rapport beschrijft voor de verschillende monitoringen welke vereisten aan een vervangend schip gesteld worden en welke mogelijke alternatieven voorhanden zijn.
Gezien de relatief ondiepe wateren waarin beide surveys plaatsvinden, verdient het vooralsnog de voorkeur met gieken te vissen om de schroefwaterimpact te minimaliseren. Begin 2017 wordt door Wageningen Marine Research een rapport gepubliceerd met daarin resultaten van een vergelijkende visserij tussen de Stern (gieken) en Navicula (A-frame achterover). Aan de hand van deze rapportage zal duidelijk worden wat de impact mogelijk is en welke methode de voorkeur heeft.

Wageningen Marine Research was requested by ACRB B.V. to investigate the fishing activities around the BBL pipeline. This gas pipeline crosses the southern North Sea from Balgzand (near Den Helder) in the Netherlands to Bacton in the UK (230km). This pipeline is abbreviated as the BBL pipeline. Part of the activities deployed by the owner of the BBL pipeline is to secure the integrity of the pipeline, which includes checking burial status, detecting free-spans and investigating internal and external threats to the integrity of the pipeline. Fishing is considered as one of the external threats to the pipeline where a collision with fishing gear could damage the pipeline, the fishing gear, the vessel or the crew. Therefore in areas with substantial fishing activity, extra care should be taken. Such a risk inventory becomes more and more common day practice of submarine pipeline and cable owners where discussions now focus on how to best spend effort on protecting pipelines and where to relieve specific burial requirements.

In deze studie is op basis van gesprekken met Nederlandse staandwantvissers en sleepnetvissers verkend in hoeverre het doorvaren van staandwantnetten kan leiden tot het ontstaan van zwerfvuil. Volgens de Nederlandse staandwantvissers zijn de problemen uit voorgaande decennia voorbij door de goede communicatie tussen staandwantvisssers enerzijds en sleepnetvissers anderzijds. Netten worden tegenwoordig nog doorvaren indien niet goed bekend is dat bepaalde activiteiten, zoals baggeren, gaan plaatsvinden. Doorvaren netten worden door de staandwantvissers zoveel mogelijk weer verzameld en eindigen dan niet als zwerfvuil. Door sleepnetvissers wordt aangegeven dat netten van Deense staandwantvissers regelmatig doorvaren worden, vooral gedurende de zomerperiode en binnen de 12-mijlzone. Deze netten worden losgesneden en dan òf als afval meegenomen naar wal, òf achtergelaten indien de netten zijn verankerd. Het is dan onduidelijk of de stukgesneden netten achterblijven als zwerfvuil. Op basis van de bevindingen wordt aanbevolen een betere communicatie te faciliteren tussen staandwantvissers en andere gebruikers van de kustzone.

The Dutch ministries of Infrastructure and Environment and the ministry of Economic Affairs are developing management measures to protect the seafloor in the Frisian Front (FF) and Central Oysterground (CO) areas of the Dutch EEZ. In the consultations with the fishing industry and environmental NGO’s the following questions were raised about the impact of the flyshoot fishery: a. Where do fishermen deploy flyshoot (or other bottom seine gear) and what is the value of the landings taken. b. What are the effects of the flyshoot on the ecology of the benthos in general, and in particular in the areas where this gear is being deployed. What is the recovery potential of the seafloor if there would be no flyshooting. c. How do the effects of the flysoot compare to the effects of the other towed demersal gear in the typical flyshoot grounds.

In the recent decennia, many developments have taken place to improve the selectivity of the shrimp fishing gears. Recently, the development of a pulse gear for catching shrimps has taken up again as an opportunity to decrease discards, inspired by developments in the flatfish pulse fishery. Currently, the Dutch government sees the pulse application in shrimp trawls as a promising alternative to the conventional ones, particularly in reducing discards and seabed disturbance. For the shrimp pulse fishery, a long-term research agenda is still lacking. Therefore, the Ministry of Economic Affairs asked IMARES and ILVO to develop a research agen-da for the shrimp fishery pulse in consultation with the shrimp fishing industry. The underlying question that will be answered by implementing the research agenda is: What are the (in)direct effects on the marine ecosystem of fishing with shrimp pulse gear?

Als vervolg op het VIP-project HydroRig I waarbij een vistuig werd ontwikkeld als alternatief voor de boomkor met manipulatie van de waterstroming in het voortuig van het vistuig is in 2013 en 2014 een nieuwe variant HydroRig II beproefd door de firma Geertruida B.V. Dit vistuig had een breedte van 15 m waarvoor ontheffing was verkregen en wielen die de sloffen vervingen. De praktijkproeven lieten een goed vangstresultaat op schol zien in vergelijking met schepen in de buurt vissend met ca. 10% brandstofbesparing. Een gedetailleerde vangstvergelijking is nodig om ecologische voordelen beter te kwantificeren.

This research project examines the concerns and questions of European stakeholders about pulse fishing, in order to assess to what extent the knowledge agenda on pulse fishing covers these issues. To get a first impression of the concerns about pulse fishing, and to get an idea of the stakeholders that express these concerns, an analysis was conducted of media items in the states bordering the southern North sea where pulse gear is used. In addition interviews were held with representatives from governments, NGOs, the fishing industry and scientists, and seven meetings were observed, national and international, where pulse fishing was discussed. An inventory was made of the substantive concerns that the stakeholders have about pulse fishing.

De Stichting Vissenbescherming heeft de hulp van de wetenschapswinkel van Wageningen UR ingeroepen. Zij vraagt haar te ondersteunen met onderzoek dat een stap voorwaarts kan betekenen op weg naar een vissenwelzijnskeurmerk voor in het wild gevangen (zee)vis. In totaal 19 studenten (3 studententeams en 2 masterstudenten) deden voor de wetenschapswinkel (literatuur)onderzoek naar a) welzijn van vissen (met name platvis) in relatie tot de visserij en b) maatschappelijke agendering op het gebied van vissenwelzijn. Op grond van een literatuurstudie wordt geconcludeerd dat steeds meer wetenschappelijke argumenten erop wijzen dat ook vissen pijn lijden en emoties kunnen ervaren. Voor diegenen die deze argumenten in twijfel trekken wordt door Elder bepleit het “voorzorgsprincipe” te hanteren, waarbij ernaar gestreefd wordt het risico op pijn en leed bij vissen zoveel mogelijk te voorkomen.
