Farewell Gesine!
Related to the movement to Bremerhaven and after four years of work for agri benchmark Fish, Gesine decides to look for new challenges. Her last project about the impacts of an innovative cork fish feed towards top managed German trout farms is most valuable. It is the first time, we use our farm datasets to project the effects of technical changes. We will miss you, Gesine! All the best and keep in touch, your agri benchmark Fish team!

As first author ofEstablishing a Benchmarking for Fish Farming. Profitability, Productivity and Energy Efficiency of German, Danish and Turkish Rainbow Trout Grow-out SystemsTobias Lasner received the Thünen Award for Applied Science 2017. Thünen President Prof Dr Folkhard Isermeyer and chairman of the association “Friends of Thünen Institute” Mr Lorenz von Schintling-Horny congratulate the honoree to the excellent work done, published in Aquaculture Research (48). Tobias Lasner thanks a lot his co-authors Dr Alexander Brinker, Prof Dr Ferit Rad and Dr Rasmus Nielsen for their hard working co-authorships. Thank you!

New Headquarter
The Thünen-Institutes of Fisheries Ecology and Sea Fisheries move from Hamburg to Bremerhaven at the North Sea coast in 2018. Thus, Bremerhaven will be the new home of agri benchmark Fish. The brand-new institute building offers everything a fisheries and aquaculture researcher looks for, including one of the most innovative experimental aquaculture facilities in the world and an amazing view of the old fisheries seaport. agri benchmark Fish will definitely benefit from the fact that Bremerhaven is an important place for the European seafood processing industry and seafood trade. The last team member will move in May, 2018.

New Aquaculture Journal
The journal Mediterranean Fisheries and Aquaculture Research -MedFAR is launched by the Faculty of Fisheries, Mersin University. It is an international peer-review open access journal aiming to contribute to the development of sustainable capture fisheries and aquaculture industries in the region of the Mediterranean and Black Sea by establishing a freely accessible platform for dissemination of scientific findings, facilitating knowledge sharing and promoting science-industry interactions at regional level. In this regard; globally acknowledged principles for open access policies and guidelines towards best practices in publishing scientific journals are fully respected. MedFAR will publish 3 issues annually. agri benchmark Fish member Prof Dr Ferit Rad is the managing editor. Have a successful start MedFAR!

Dear friends of agri benchmark,
Tobias Lasner (©Thuenen-Institute) looking back, 2017 has been a quite dynamic year. agri benchmark Fish is participating in two large EU research projects – CERES and SUCCESS. More importantly, there is a growing demand of our expertise in implementing the typical farm approach. The Thünen Institutes of Fisheries Ecology and Sea Fisheries moves from Hamburg to Bremerhaven. The last agri benchmark Fish scientific article was honored by an award. Find this and further exciting news in our third agri benchmark Fish newsletter.
Enjoy reading, enjoy life! A happy new year 2018!
Best regards,
Tobias Lasner
agri benchmark Fish Coordinator

Results on Carp Farms in Poland and Germany
Carp farmers face many challenges: changed consumers’ preferences; price competition; value chain’s imbalances; poor willingness to adapt innovations; lack of farm successors; high fish losses due to cormorants and other animals; diseases; shortage of water; poor infrastructure; de-population of rural areas. In the carp regions Aischgrund (Germany) and Barycz Valley local stakeholders have established a wide range of region-marketing initiatives to attract tourists and strengthen the local identity with carp farming: guests information offices, carp festivals, fish farming museums, Protected Geographic Indication (PGI) and local labels, network of restaurants and fish farmers, pond guides, school teaching materials and new products.
Often these initiatives are supported by EU programs. However, our results show that small scale carp farms hardly benefit from region-marketing effects. Future (public) transfer payments should support small scale carp farms, to honor and maintain their ecosystem and cultural services for the unique pond landscapes.
In contrast, region-marketing seems to be a good strategy to enhance direct marketing opportunities for medium sized carp farms and hence to improve their profitability. In case of large farms, region-marketing enhances the national recognition of their products, which could have a positive impact on the demand and price development. This study is part of the EU research project Strategic Use of Competitiveness towards Consolidating the Economic Sustainability of the European Seafood Sector (SUCCESS). An article of the results will be published soon.

Economics of Cork Fish Feed
The effective removal of fish faeces from production waters is crucial for aquaculture in recirculating systems. There are different approaches on how to optimize faeces’ removal and to enhance the stability of the system. One approach is about getting floating faeces by using fish feed added with cork. This has been studied and tested under commercial conditions in southern Germany.
Both in terms of compatibility to fish physiology and technical feasibility the results were promising. New water filtration technique using faeces collector was tested to absorb the solid swimming fish faeces. By that water quality improves significantly, which enables a higher production within the same production system. At the same time, this has consequences for investments (and depreciation) as well as higher feed costs have to be expected.
Cork Fish Feed
We analysed the application of the new feed and its impacts towards trout farm’s profitability using the top-managed trout grow-out farms DE-TRR-80 and 500 as examples. Under different scenarios, the results show, that larger farms like DE-TRR-500 would enhance their profitability to a significant degree with the new feed. The results will be published soon.

Focus Group on Salmon in Ireland
As part of the EU research project Climate Change and European Aquatic Resources (CERES ) we collected data of a typical Atlantic salmon net cage production system in Ireland. Thereby we gained very interesting insights into a highly professionalized aquaculture structure, which is contrasting to most of the freshwater production systems (small scale) we know in Europe.
Salmon farm - Ireland
Irish salmon farms are specialized in organic production, providing the biggest share of organic salmon within the EU and thereby establishing a niche to set themselves apart from their competitors Norway and Scotland. We are looking forward to collect further typical farm data within the salmon industry and the resulting comparison of the sector as well as under climate change aspects which will follow.

Conferences and Events
From February 27th – March 1st, 2018, the special session “agri benchmark meets CERES” takes place at the Thünen-Institutes of Fisheries Ecology and Sea Fisheries in Hamburg. Experts from EU Horizon 2020 Project Climate Change and European Aquatic Resources (CERES ) discuss typical farm and vessel datasets together with the agri benchmark Fish network members and the coordination team. The special focus is on salmonids (trout and salmon), seabass and seabream production systems as well as on cod and mixed fisheries vessels.
Later on in the CERES project progression, the agri benchmark datasets will be analysed according to three scenarios reflecting the impacts of climate change towards a variety of aquatic production systems on farm and vessel level in the light of environmental changes as well as different pre-defined future scenarios on society, economy and policy.

Danish fish farm Danish RAS trout farms remain competitive thanks to productivity growth
The Danish trout sector is traditionally dominated by pond aquaculture. The tightening of environmental regulations in recent decades has led to an ongoing restructuring of the Danish trout farming: Larger farms using recirculating techniques internalize the costs of effluent discharge and enhance productivity.
