TY - JOUR AU - Maravelias, Handling editor: Christos AB - Abstract A new EU Common Fisheries Policy (CFP) came into force on 1 January 2014. Article 15 of the new CFP basic regulation introduced a discard ban or landing obligation (LO) in EU fisheries whereby the discarding of quota species is prohibited. There is an urgent need to understand the impact of this new regulation on the UK fishing industry and fishing industries elsewhere in Europe. This study conducted a discard ban trial to provide an opportunity for the fishing industry to demonstrate what a LO would mean for them. The results are mostly illustrative and qualitative, designed to inform policy decisions and identify areas of future work to assist in the implementation of the discard ban. Five recommendations are made, which if adopted, would significantly improve the prospects of a smooth transition to a largely discard-free EU fishery. Introduction Article 15 of the new EU Common Fisheries Policy (CFP) basic regulation introduces a discard ban or landing obligation (LO) in EU fisheries whereby the discarding of quota species will be prohibited (European Parliament and Council Reg. No.1380/2013). Previously, market and regulatory forces motivated fishermen to discard their catches, whereby if the market was unfavourable catches would be returned to the sea, and if a vessel operator exhausted the quota for a species, they were legally required to discard any further catches of that species. But in the reformed CFP, the European Commission is seeking to reduce unwanted catches and eliminate discards, and quotas on total catch will place a direct cap on fishing mortality, requiring all catches (not just landings) to be deducted from the quota, and once the quota of a species is reached, fishing activities must stop. This represents a fundamental change in European fisheries policy as it switches the focus from the regulation of landings to the regulation of catches. All catches of pelagic and demersal species which have a quota, will have to be landed (in the Mediterranean where there are no quotas, the discard ban will apply to all species with a minimum legal landing size). There are potential exceptions from the discard ban when these fish do not have to be landed, where the fish are prohibited for conservation reasons; or will be used for live bait; or have demonstrably high survival rates when discarded. Similarly, a small amount (de minimis) of up to 5% (after a transitional period of 4 years: up to 7% in years 1 and 2 of the discard ban and 6% in years 3 and 4 of the discard ban) of the total catch may be discarded if, either there are disproportionate costs of handling and storing the fish on board, or improving selectivity is proven to be difficult (European Commission, 2013). The discard ban has been phased in from 1 January 2015, when it was applied to pelagic stocks, to be extended to cover all other regulated stocks between 2016 and 2019. Unwanted catches of species which are not subject to the LO can continue to be discarded. The aim of the LO is to make fishing more environmentally and economically sustainable as fishers change their methods to maximize the revenue from their quotas. The shift of focus from the regulation of landings to that of total catches brings with it the expectation that, because the costs of catching unwanted fish will be internalized for fishing businesses, fishers will want to avoid catching low value fish and the most quota restricted species. For instance, in order to maximize the revenue from the catch quotas, fishers will need to avoid catching fish that would result in a curtailment of their fishing season (referred to as “choke species”), and avoid catching undersized, and low-value fish, which would be deducted from their quota for little or no profit. The act of having to bring the catch to shore, the discard ban, is almost secondary, and was brought about through lobbying and public demand (Borges, 2015), but also due to the new requirement to monitor the full catch. Consequently, the latest reform of the CFP will lead to changes not only in fishing operations, but also in fish handling and marketing, as previously discarded catches are brought to shore. There is therefore a need to evaluate how the LO will impact on fishing vessels, fishing practices and the economic viability of fishing fleets. Several recent studies have focused on discard bans in anticipation of the implementation of the LO. For example, Condie et al. (2013) studied historic observer and log book data to assess the economic impact of a discard ban on the North Sea otter trawl fishery, and concluded that because vessel operators will be managed on their full catch (not just landings) they will have an incentive to operate more selectivity, whereas a discard ban, in isolation, generates little such incentive. Condie et al. (2014b) reviewed the literature on discard bans in Alaska, British Columbia, New Zealand, the Faroe Islands, Norway, and Iceland, and stated that although discard bans can result in a reduction of discards, they depend on a substantial level of surveillance and/or economic incentives. To further support this, another desktop study of discards in the North Sea found that a discard ban in the North Sea for cod, haddock, saithe and herring could offer substantial benefits, but it was the use of real-time area closures, gear modifications, and electronic monitoring systems which would help ensure compliance and effectiveness (Diamond and Beukers-Stewart, 2011). Ensuring access to existing quota will be critical to the successful implementation of the landing obligation (Poseidon, 2013), for example, the retrospective analysis of various fleet segments in the UK, showed the potential economic impact of choke species to be very substantial (Russell et al., 2015). To help with the successful implementation of the LO, the regulation also includes the use of new flexibilities in quota management. These include interspecies and inter annual quota flexibility mechanisms (de Vos et al., 2016) or using alternative stock reference points (García et al., 2016). The importance of using these flexibilities has been demonstrated in simulations, for example, by offsetting catches of cod against saithe, negative economic impacts could be avoided in the North Sea trawl fishery (Simons et al., 2015). Unlike these desktop and modelling studies, the current study is a bespoke sea trial carried out in 2012/2013 to evaluate the likely effects of the landing obligation in England, and was the first study of its kind in Europe. The objective of the work was to provide practical experience of a discard ban and use that to stimulate feedback from the participants to gain an insight into the direct practical, and also wider implications, for the fishing industry in implementing the LO. The importance of such trials was emphasized by one of the main regional stakeholder group, the North Sea Advisory Council (NSAC, 2013). The aim of this study was to provide practical recommendations for fisheries managers to support a successful implementation of the landing obligation. Methods The trial focussed on how fishing practices, catch handling, storage, and transport could change as a result of the obligation to land all catches, and it also reported on monitoring and data issues and direct economic aspects of the LO. It involved eight vessels of different sizes (four under-10 m and four over-10 m), gear types, from different ports along the south coast of England, for up to 5 months (Table 1). The English fishing fleet is made up of around 3139 vessels, 83% are of length 10 m or less, 12% are of 15 m or less, and the remainder are over 15 m in length; of the largest vessels there are around 26 English registered vessels 30–50 m in length (MMO, 2016). This project was initiated in 2012 before the final details of the new CFP were agreed in 2013, so although the inclusion of a discard ban was anticipated, there was uncertainty around the exact details of the policy. The trial simulated a discard ban on all commercial species—defined as species for which some part of the catch is normally landed and sold—and so also included non-quota (unregulated) species. This differs from the final agreed LO which applies only to regulated species. These differences are accounted for in the reporting of this study. A total of 128 fishing trips was conducted during the trial, of which 40 had a scientific observer on board, equating to observer coverage of 31% for the trial. All fish caught were documented using the following methods. There was 100% scientific observer coverage for the under-10 m vessels, and 10% observer coverage for the over-10 m vessels owing to resources limitations. The observers weighed all the unwanted catches for the under-10 m vessels at the point of landing. For the over-10 m vessels, catches were not weighed either by skipper or observer; instead observed weights were estimated by converting fish length measurements from the whole catch using length-weight relationships, while the skippers simply estimated the weight from experience. The skippers’ data were validated using the independent data from observed trips and data from a fishmeal plant, which received most of the otherwise discarded material. Table 1.

The new CFP regulations have replaced MLS with minimum conservation reference sizes (MCRS), below which, fish must be landed but not made available for direct human consumption markets. Any prohibited species or zero TAC species could not be landed in the trial and were recorded before being released. For each trip, skippers of over-10 m vessels recorded the catch destined for the direct human consumption market, for the non-human consumption market, the reasons for otherwise discarding these catches, and the destination of this material. Regarding the disposal of the unwanted catch, it was a condition of the trial that there was somewhere for it to be received when landed. The most suitable option was to send the material to the United Fish Industries (UFI) plant at Grimsby, UK, to be converted into fishmeal. This provided a guaranteed outlet for the discarded material. All quota species which were either under the legal size or for which there was insufficient quota to land, had to be processed into fishmeal. Although some other outlets were used for non-quota species, most of the otherwise discarded catches were sent for fishmeal. In reality, the industry will be able to access a range of non-human consumption markets to maximize profits from the previously discarded catch. The vessel owners received payment for material sent to UFI—participating vessel owners had to specify what material was being sent and where it came from, and verified that the material was suitable for use as fishmeal. This evidence is required by Feed Materials Assurance Scheme (FEMAS) to demonstrate that the material is safe to use as animal feed. Transport of the material from the ports to Grimsby was also arranged before the trial started, and was paid for by the project. At the end of the trial, the perceptions and experiences of the participants were gathered from all skippers, market managers and managers from UFI. These discussions were based on questionnaires with open-ended questions. One researcher conducted face-to-face interviews; the under-10 m skippers were interviewed as a group. Questions were tailored to the role of the participants but included the three key broad questions (Table 2). Each interview began with a description of the proposed discard ban policy, the project objectives and a presentation of the data generated from the project. The interviews were transcribed; coded-based themes and concepts were drawn from them; and then a summary text of this information was produced. Table 2.

The results from the over-10 m vessels indicate there was a trend for the skippers’ estimates of unwanted catches to be slightly lower than the observers’, but overall, there was considered sufficiently close correlation between the estimates (R-squared 0.85; slope 0.78) to enable the use of the skippers’ data in a broader analysis. This was reaffirmed using independent data from the fishmeal plant which recorded weights of all material received. This recording mechanism at the point of delivery of the non-human consumption material provided a useful confirmation of the skippers’ reported landings. All the fish were believed to be documented, the timing of the fish arriving at the fish meal plant correlated closely to the landing of the otherwise discarded material (Figure 1), and there was a high level of confidence in the quantities and in the reported destination of those catches at first sale.

Discard data analysis During the trial, the total recorded weight of unwanted catches caught by all vessels was estimated to be 27 171 kg. Of this total quantity, 70% came ashore and was sent to the fish meal factory, and 30% was released at sea. Of the catch released at sea, most (71%) could not be landed under the conditions of the trial because the species had either a zero quota or was prohibited (mostly spurdog, undulate ray and common skate). The remainder of the catches were released because of a perceived high survivability by the skippers, and consisted of skates and ray species, and to a lesser extent conger eel, brill, turbot, and Common (Dover) sole. Of the unwanted catch that was landed for fishmeal, 68% was of quota species; Table 3 shows the total weight of each quota species landed during the trial and a breakdown of the reasons for otherwise discarding these fish, as given by the skipper. The remainder of the catch (32%) that went for fishmeal, was of non-quota species; most of which (95%) was bib, dab, dogfish, and gurnards. Table 3.

The unwanted herring and horse mackerel and most the mackerel were over the MLS but would have been discarded because they were not of marketable size; some of the unwanted plaice and whiting was also of unmarketable size, although above the MLS. Overall, 12 453 kg of species regulated by quotas, and therefore subject to the LO (Table 3), were landed in this trial and would have otherwise been discarded, equating to 97 kg per trip (128 trips). When excluding fish discarded due to quota restrictions, which will not occur under the LO, this gives 68 kg per trip. Some of this catch was discarded due to market forces, and therefore could go to the human consumption market, or it was damaged and would not need to be landed. This left only 13 kg of the total 212 kg of unwanted catch per average trip, which would have had to be landed and sold to a non-human consumption market. The total weight of unwanted catches that were not of quota species, was 14 764 kg, equating to 115 kg per trip and under the LO, there is no requirement to land these unwanted catches. The values presented here are not considered representative of the fleet but provide indicative values for the participating vessels. The results demonstrate that a substantial quantity of unwanted catches will continue to be returned to the sea under the Landing Obligation, however, anticipated changes in fishing behaviour and gear selectivity would likely reduce unwanted catches overall. Cost of landing otherwise discarded catches The costs associated with bringing the otherwise discarded catches ashore was calculated at £280 per tonne (this included box rental and storage on market, box loading, forklift operation, refrigeration, pallet charge, ice, and transport). The total revenue of the material received by UFI had a value of £2640, which meant the otherwise discarded catches were sold at a loss of £2690 or £122 per tonne. The main themes and concepts derived from the interviews are presented for each key question. How representative of normal fishing practice was the trial period? The catches taken during the trial were considered by participating skippers to be representative of the period of the trial. Skippers stated that the gears that they used, and locations fished, were the same as usual and no change was made to their quota holdings. They did state that discard patterns can vary seasonally and under different levels of quota restriction and so results will have differed had the timing of the trial been different. In total, fifteen species with quotas, and also skates and rays collectively, were discarded and skippers said that the quotas for cod, plaice, haddock, and Dover sole were the most likely to be exhausted first, and so could “choke” their fisheries. Skippers stated they do not target these species, so these catches are incidental, but only small catches could exhaust their limited quota and prevent them from fishing. The extreme example mentioned of this was for species with a zero quota, for which, under the regulation, catching a single fish could close a fishery. Undulate ray and Spurdog were the species for which this issue was most important for the participating vessels. What were the logistical and operational implications of the discard ban, including costs? Interviewees identified potential economic costs and charges associated with sorting, landing, and transporting the otherwise discarded fish, including: losses associated with foregone catches after cessation of fishing due to exhausting quotas (choke species); losses associated with counting undersized fish (
