Executive Summary: This report is intended to contribute to a successful implementation of the landing obligation (LO) of the reformed Common Fisheries Policy of the EU. The work package focuses on how unavoidable, unwanted catches (UUC) can be utilised once they have been landed. The first step in that work is to provide an overview of current and expected supplies of UUC, where and when they will be landed, what are the available facilities and how the set-up is at the landing harbours to cope with changing supplies effected by the LO. This document addresses that by focusing on five selected fisheries, which will be key case studies in future work within the work package i.e. Bay of Biscay (landings in the Basque country), North Sea (Danish fleet) and Iceland. Landing and discarding statistics from the Mediterranean (bottom trawlers landing in Mallorca) and the English Channel (French fleet) are also analysed. The role of Iceland in this report is to provide an example of where a LO has been successfully in effect for decades. Estimating future landings of what used to be discarded under a policy regime that obliged fishermen to discard UUC cannot realistically take into consideration changes in behaviour of fishermen that inevitably will occur. Once the LO is implemented the fishermen will change their practises, for example by avoiding areas with high volumes of UUC or by applying more selective fishing gear. The historic discard data can therefore only give indications on what UUC are likely to be landed in certain areas, as well as when and by which fleets. The general results from all of the case studies is that relatively few species and fleets account for most of the discards. There are also in most fisheries very few harbours that stand out, representing vast majority of the discards. The available facilities are in most cases going to be sufficient to cope with changing supplies of catches intended for production of products for human consumption.

Currently industrial citrus by-products represent a relevant environmental issue. The main aim of this work was the chemical characterization of the different bioactive compounds obtained after hot air-microwave drying (HAD+MW) of orange by-products, and their further conversion into three upcycled ingredients with health-related benefits: aqueous extract, ethanolic extract and dietary fibre. Total phenolics, antioxidant capacity, individual phenolic acids, flavonoids, limonin and carotenoids were monitored during blanching and colour extraction steps by analysing fresh by-products and process co-products: an aqueous extract rich in polyphenols and an ethanolic extract rich in carotenoids. After drying, the resulting fibre was characterized in terms of chemical composition, soluble and insoluble dietary fibre content and particle size. Technological properties and colour were compared to those of commercial citrus fibre. Energy and time consumption were compared with conventional hot air drying (HAD). Most polyphenols (50-65 %) and limonin (70 %) were extracted during the blanching step. 86 % of carotenoids were removed by soaking in ethanol. The orange fibre obtained had 71.9 g DF/ 100 g and antioxidant properties (205 mg TE/ Kgdm). Whiteness, water retention capacity and oil retention capacity were similar to commercial citrus fibre. HAD+MW reduced drying time and energy consumption by up to 50 % compared to HAD. ; This research work was co-funded by LASAIFOOD project financed by the Basque Government, Ministry for Economic Development and Competitiveness

The European Common Fisheries Policy (CFP) has established a landing obligation (LO) and the need for proper management of bycatches without incentivising their capture. Food use is the priority option but only unwanted catches (UWC) above minimum conservation reference size (MCRS) can be used for direct human consumption. As a result, other options, such as animal feeds, industrial uses or energy, should be considered to valorise landed < MCRS individuals. Two approaches have been developed to help select the best available option for processing UWC. The first methodology is based on a multi-criteria decision analysis (MCDA) using an analytic hierarchy process (AHP) that considers technical, economic and market criteria. As a sample case, we chose the Basque fleet fishing in the Bay of Biscay, developed within the H2020 DiscardLess project. The second approach is based on the simultaneous analysis of both economic and environmental aspects. This was applied to the case of Spanish bottom trawlers operating in ICES sub-Divisions VIIIc and IXa. Finally, various food products and bio compounds from typical UWC biomass were obtained in a pilot food processing plant developed within the LIFE iSEAS project ; DiscardLess project has received funding from the European Union's Horizon 2020 Framework Programme for Research and Innovation under grant agreement no. 633680. Life iSEAS has been co-funded under the LIFE+Environment Program of the European Union (LIFE13 ENV/ES/000131)
