WorldFish hopes that its Africa Aquaculture Research and Training Center in Egypt will help ensure that 40 percent of the total fish consumed on the continent will be met by aquaculture by 2025. This ambitious target has been set by African governments and the WorldFish center is helping by providing training on best-practice techniques to workers in the fish farming sector across the continent. To date, over 1690 government officers, university staff members, farmers, extension agents and researchers from 105 countries have received training, according to Kate Bevitt of WorldFish. “We learned many different techniques in aquaculture and hopefully when I get back to my country it will help in capacity building,” said training participant Folani A Olayinka, a fisheries officer from Nigeria. The best-practice training programs are based on findings from the center’s research into new and improved fish farming technologies, which has been ongoing since the center opened in 1998. Since 2000, the center has run a breeding program for a faster-growing strain of Nile tilapia, known as the Abbassa improved strain. Dissemination of the Abbassa strain has benefited many farmers in Egypt, the third-largest tilapia-producing country in the world. “I used to produce four tons of tilapia,” explained Egyptian fish farmer Hamada Refaat Attia. “But now, after using the Abbassa strain, the total production of my ponds is about five tons.” Spread over 62 hectares in the Nile delta, the center has 185 earthen ponds, 75 indoor concrete tanks and a research laboratory. These facilities are used by research institutions and private businesses from Africa and beyond to engage in collaborative research with the center. In 2016, the global feed manufacturer Skretting partnered with WorldFish to establish a new Fish Nutrition Research Unit at the center. “The current experiments aim to evaluate the performance of local raw materials on fish growth, survival and their digestibility,” said Mahmour Asfoor, Marketing and Communications Assistant Manager for Skretting in Egypt. With 30 percent of Africa’s population currently undernourished, it is hoped that the center’s research and training will enable the growth of aquaculture and lead to enhanced food and nutrition security across the continent.

The global seafood trade is dominated by a handful of large companies that control up to 16% of the Earth’s most important fish resources. A new initiative made public on December 14, 2016, now aims to change the international fishing industry. The initiative covering all the world’s oceans made up by eight of the world’s largest seafood companies (Maruha Nichiro Corporation, Nippon Suisan Kaisha [Nissui], Thai Union Group, Marine Harvest ASA, Dongwon Industries [owner of Starkist in the US] Nutreco [owner of Skretting], EWOS/Cargill Aqua Nutrition, Cermaq) and called “Seafood Business Ocean Stewardship”. Among others the initiative aims to “clear-out” illegal IUU fisheries and inhumane working conditions, such as slavery and human trafficking. “We are part of a small but very influential group, and we have a responsibility to ensure that the seafood industry is not only profitable but also sustainable in line with UN development goals, particularly related to the sea. This group of companies represents a global force that can make a difference,” commented Geir Molvik, CEO of the Norwegian (Mitsubishi-owned) salmon farming company Cermaq, in a statement today. These eight companies — with large impact on global seafood trade — express strong concern about the future of the ocean as a result of “a lack of environmental strategy and inadequate resource management”. One of their commitments includes “Improving transparency and traceability” in their own operations. Those eight companies are also scrutinized in Seafood Intelligence’s ‘Top 100’ benchmarking report of sustainability reporting / transparency, about to be released. The ‘Top 100’ report highlights in detail – indicator per indicator – most of the shortcomings of the world’s largest seafood firms’ sustainability reporting, and highlights the ongoing progresses to date in the realm of sustainable seafood transparency. The aim of the Seafood Intellligence ‘Top 100’ is to provide a tool for seafood companies & industries to better address their level of transparency re. sustainability issues of concern to their stakeholders, assist them in establishing Sustainability & #SeafoodEthics policies. It offers a unique benchmark to follow yearly their performance against that of their competitors, and also provides a unique database/tool for purchasers, retailers, policy-makers, researchers, NGOs and all those concerned with the state of sustainability and transparency in the realm of seafood and oceans to review the performance of the ‘Top 100’.

In its continuous quest for innovation in animal nutrition and aqua feed, Nutreco is launching a new way to kick-start breakthrough solutions with the Nutreco FeedTech Challenge. Centred around the question 'What is your breakthrough innovation - that CANNOT wait?' Nutreco calls for the brightest minds to help realise sustainable food production for a growing world population. The winner receives a unique prize in the form of a scientific on-farm validation trial in one of Nutreco's research farms. Nutreco has been at the forefront of some of the major breakthrough innovations that have made food production more sustainable. With a world population growing to over 9 billion by 2050 and finite natural resources, the animal nutrition and aqua feed industry needs to step up its efforts. The Nutreco FeedTech Challenge offers a 'greenhouse & pressure cooker' environment aimed at identifying, nurturing and enriching high potential concepts in pilot or proof-of-concept phases. Nutreco CEO Knut Nesse points out that the validation trial for the winner is the biggest boost any start-up could wish for. "At Nutreco we focus on bringing new science and technologies to farmers, faster and more effectively. We know that validation and knowledge on how to apply new technologies in a real farm environment are crucial for farmers to embrace innovation." "This challenge and in particular the validation trial can provide a significant contribution to introducing new breakthrough innovations into real life. For start-ups it is a great opportunity to accelerate the development of their innovations, possibly even leading to a funding offer from Nutreco or one of our partners." Over a competition period of two months, contestants will participate in an online platform where entries are open for comments, discussions and contributions from others. This provides a unique opportunity to connect with other start-ups, industry experts, scientists, and ultimately with farmers and the rest of the world. In that respect, the Nutreco FeedTech Challenge is different from most other start-up competitions. Also because the winner is not rewarded with a cash prize, but with a high-value and rare opportunity for a scientific on-farm validation trial. Centred around the question 'What is your breakthrough innovation - that CANNOT wait?', the Nutreco FeedTech Challenge hopes to inspire start-ups with breakthrough innovations in the following three areas: More information on the themes can be accessed via http://www.nutrecofeedtechchallenge.com. The international jury is chaired by Prof. Dr. Ir. Daniel Berckmans of KU Leuven. He is an expert in animal and human health engineering, and one of the pioneers of precision livestock farming. The other members of the jury are: Every contestant will be a winner The Nutreco FeedTech Challenge is set up in such a way, that every contestant is a winner. In the first phase from 29 November 2016 until 17 January 2017, entries receive valuable feedback and enrichment from industry experts and scientists. An expert jury will then select ten finalists, who will receive further feedback and training in pressure cooker sessions during the two-day Nutreco FeedTech Challenge Event on 22 and 23 February in The Netherlands. At this event, the winner will be selected and receives a scientific on-farm validation trial in one of Nutreco´s research farms, including a validation report. Nutreco is a global leader in animal nutrition and aqua feed. Nutreco's advanced feed solutions are at the origin of food for millions of consumers worldwide. Quality, innovation and sustainability are guiding principles, embedded in the Nutreco culture from research and raw material procurement to products and services for livestock farming and aquaculture.

Following a 'keystone dialogue' between scientists and seafood industry, 8 of world's largest seafood companies issue 10-point statement committing to action on ocean stewardship Eight of the world's largest seafood companies have issued a ten-point statement committing to action on ocean stewardship following the first "keystone dialogue" between scientists and business leaders. Through the "keystone dialogues" - a new approach to engage major international businesses in global sustainability challenges - companies have committed to improving transparency and traceability and reducing illegal, unreported and unregulated fishing in their supply chains. Antibiotic use in aquaculture, greenhouse gas emissions and plastic pollution will also now be prioritized. And the businesses commit to eliminating any products in their supply chains that may have been obtained through "modern slavery including forced, bonded and child labour". The statement says signatories "represent a global force, not only in the operation of the seafood industry, but also in contributing to a resilient planet." It was signed by the two largest companies by revenues (Maruha Nichiro Corporation and Nippon Suisan Kaisha, Ltd), two of the largest tuna companies in the world (Thai Union Group PCL and Dongwon Industries), the two largest salmon farmers (Marine Harvest ASA and Cermaq - subsidiary of Mitsubishi Corporation) and the two largest aquafeeds companies (Skretting - subsidiary of Nutreco, and Cargill Aqua Nutrition). To implement the commitments the companies plan to create a new initiative - Seafood Business for Ocean Stewardship - that will, for the first time, connect wild capture fisheries to aquaculture businesses, connect European and North American companies to Asian companies and connect the global seafood business to science. The inaugural dialogue, initiated by the Stockholm Resilience Centre, took place 11-13 November at the Soneva Fushi Resort on the Maldives under the patronage of HRH Crown Princess Victoria of Sweden - Advocate for the UN Sustainable Development Goals (SDGs). The initiative was a unique meeting between CEOs, senior leadership of major seafood companies, leading scientists from the Stockholm Resilience Centre, and advisors including The Honorable Dr Jane Lubchenco of Oregon State University and U.S. Science Envoy for the Ocean - U.S. State Department, Mr Volker Kuntzsch, CEO of Sanford Ltd., Mr Rupert Howes, CEO of Marine Stewardship Council, and Ambassador Magnus Robach, Swedish Ambassador to Japan. "We depend on a stable and resilient planet for human prosperity. However, science is already providing evidence that we have entered the Anthropocene, an epoch where humanity is now challenging the stability of Earth and its ocean," the statement goes on to say. The dialogue is the first between scientists and "keystone actors" a term coined in 2015 by Carl Folke and Henrik Österblom, science directors at the Stockholm Resilience Centre. Keystone species play a disproportionate role in ecosystems. Increasingly, large transnational corporations now play this role, for example, in the ocean and in rainforests. Österblom led research identifying the keystone actors in the world's oceans. The team identified 13 transnational corporations controlling 11-16% of wild marine catch and up to 40% of the largest and most valuable fish stocks. "We invited the leaders of these companies to a dialogue to build trust and develop a common understanding about the state of the ocean," said Österblom. "We were delighted so many companies accepted our offer. This shows they are aware of the urgency of the situation and willing to engage in these issues." According to related research published by a group of U.S. scientists in 2016, good management of global fisheries could lead to increase in annual catches of over 16 million metric tons and $53 billion in profit compared with remaining on the current trajectory. Stockholm Resilience Centre Director Johan Rockström said, "The small concentration of multinational companies means that CEOs are significant leverage points to effectively engage in transforming the entire seafood sector towards more sustainable practices". Chair of the dialogue, and founding director of Forum for the Future, Jonathon Porritt said, "It's hugely encouraging to see these leading companies in the global seafood industry making such critical commitments to help protect the world's ocean. This combination of world-class science and inspirational corporate leadership is a powerful one - and I've no doubt we'll need to see a lot more of it over the next few years." The organization was a key supporter of the dialogue. Myoung W Lee, CEO of Dongwon, one of the largest tuna companies, said, "It's remarkable that seafood companies came together to discuss the sustainability and development of the seafood industry and lay grounds for ocean stewardship. I am honored to have contributed to such a significant, historic event and will ensure that Dongwon does our part to uphold the agreement." Cermaq CEO Geir Molvik said, "Cermaq is very much engaged in Sustainable Development Goal 14 - life below water - and have encompassed the SDGs in our business strategy. Working with other keystone actors in the global seafood sector is important because it's only through partnerships we can efficiently pull in the same direction and make significant changes." President of Cargill Aqua Nutrition, a major aquafeed company, Einar Wathne said, "This initiative has a truly global perspective, from east to west. That makes me believe that we will have a powerful impact when addressing the challenges we have in our oceans and marine ecosystems, with the UN Sustainable Development Goals as our guideline." "Creating more awareness of the opportunities - and business necessities - of managing seafood sustainably should be a key priority for CEOs," added Jean-Baptiste Jouffray, PhD candidate at the Stockholm Resilience Centre and co-organiser of the event. The dialogue will now be followed up with additional meetings and dialogue between science and business. A next meeting is already scheduled for next year, where more concrete joint actions will be identified.

Reviews in Fisheries Science and Aquaculture | Year: 2016
The aim of this review is to provide an update of Seriola spp. farming in the world, excluding yellowtail (S. quinqueradiata), and to identify strengths and weaknesses of these species as candidates for aquaculture diversification in different areas of the world. Farmed Seriola species other than yellowtail are yellowtail kingfish (S. lalandi) in Japan and Australia, longfin yellowtail (S. rivoliana) in the United States, greater amberjack (S. dumerili) in Japan, the Mediterranean and more recently Vietnam, and Pacific yellowtail (S. mazatlana) in North and Central America. Candidate countries for Seriola spp. farming development are China (although there are no published production statistics to date), New Zealand and the Canary Islands. The main bottlenecks for further expansion of Seriola spp. farming appear to be disease impact, lack of genetic improvement programs, and incomplete knowledge of nutrient requirements. Extensive experience from Japan, where the success of Seriola spp. farming has been based on an integrated system between producer associations, research institutes and central government, it is clear that the aforementioned technical bottlenecks need to be addressed within a framework of medium-term public policies supporting aquaculture development. © 2016 Taylor & Francis.

In order to verify the hypothesis that a formulated live food diet could completely substitute any enrichment step, an existing rotifer culture diet was transformed to slowly release the enrichment components such as protein, fat, vitamins and minerals in non-suffocating concentrations. Nutrients being present at metabolizing concentrations allowed not only gut filling but also gradually enriched the tissue of the rotifers without consuming excessive oxygen or compromising health nor reproduction of the rotifers. Similar growth and reproduction figures were registered with the traditional culture diet as with the stand-alone diet in a lapse of 9. weeks corresponding with 15 rotifer cycles and average FCR's of 1.0. The nutritional profile of the rotifers was similar to that of rotifers undergoing a classic enrichment for all major nutrients (protein, HUFA, vitamins) except for some slow enriching nutrients (i.e. taurine, Zn, Se) that could be incorporated successfully thanks to the long term enrichment approach.Besides the nutritional advantage, benefits were noticed on the practical use of the diet (i.e. direct available enriched live food at any moment); the reduced amount of losses and handling of rotifers and the stability in the process thanks to a higher degree of standardization of the operations. These optimizations lead to less damage of the live food resulting in stronger and better quality rotifers. © 2014 Elsevier B.V.

A novel Gram-stain-negative rod-shaped gliding bacterial strain, designated 35/09T, was isolated from diseased European sea bass (Dicentrarchus labrax L) in Spain. Colonies were pale-yellow-pigmented with uneven edges and did not adhere to the agar. The DNA G + C content of the isolate was 31.3 mol%. 16S rRNA gene sequence analysis indicated affiliation to the genus Tenacibaculum (family Flavobacteriaceae, phylum 'Bacteroidetes'). Sequence similarities between the isolate and type strains of other members of the genus were 93.1-97.3%. The major fatty acids (>5% of the total fatty acids) were iso-C15:0 (24.8%), iso-C15:0 3-OH (18.0%), anteiso-C15:0 (8.1%), C15:1ω6c (6.9%) and iso-C15:1 (6.2%). Genotypic and phenotypic data indicate that strain 35/09T should be classified as a representative of a novel species in the genus Tenacibaculum, for which the name Tenacibaculum dicentrarchi sp. nov. is proposed; the type strain is 35/09T (=CECT 7612T=NCIMB 14598T). © 2012 IUMS.

Improving the understanding of digestive physiology in first feeding larvae is a prerequisite for advancing diet formulations and feeding protocols. In marine fish larvae that lack a stomach at first-feeding trypsin represents the main proteolytic enzyme. CCK is one of the key regulators of digestive enzyme secretion in adult vertebrates and current knowledge suggests that it is also involved in early stages of teleosts, although this may vary between species. Here, we investigated the influence of Artemia and a commercial microdiet on the ontogenetic development of tryptic enzyme activity as an indicator for digestive capacity in first-feeding sea bass. In order to examine the regulation and feedback mechanisms in the digestive tract we followed the response of gut CCK and tryptic enzyme activity during a one-day observation depending on the feeding regime at 23. days post hatch. Larvae fed the microdiet showed a higher tryptic enzyme activity, probably as an adaptation to the higher content in complex protein in the diet. The plant protein phytohemagglutinin (PHA), added to the microdiet as a potential stimulator for the digestive system, did not induce elevated tryptic enzyme activity nor was it beneficial for growth. This was possibly due to adverse effects of too high doses. We observed an endogenous rhythm of CCK over the day, independent of the dietary treatment or short-term fasting. Higher tryptic enzyme activity in larvae fed Artemia during the day might indicate a better stimulation by live prey in the digestive tract or the superiority of a discontinuous feeding schedule in this group. We suggest that a reduction in tryptic enzyme activity after several feeding events indicates a limit in diurnal digestive capacity. Sea bass larvae are apparently able to adapt to the feeding schedule by synchronizing the tryptic enzyme activity like adult fish. © 2013 Elsevier B.V.

The effects of feeding a commercially available health enhancing aquaculture feed (Bio-Oregon's BioPro/Protec® diet) on the efficacy of two coldwater disease (CWD) vaccine formulations consisting of Flavobacterium psychrophilum 259-93B.17 (B.17) and B.17 grown in iron limited medium (ILM) were carried out in two separate trials. The primary aim of this study was to compare efficacy of the B.17 and ILM formulations in rainbow trout ( Oncorhynchus mykiss). A secondary aim was to determine if dietary alterations could enhance the immune response and/or elicit greater levels of protection. Therefore, a basal diet (BioOlympic fry diet; control feed) and an immunostimulatory diet (BioPro; IS feed) were fed to rainbow trout at 2% body weight (bwt) per day for 2. weeks prior to immersion immunization with the B.17 vaccine, ILM vaccine, or a TYES media control. A booster immunization was administered two weeks post initial vaccination, and feeding of the respective feeds continued for one additional week at which time all groups received the control diet until the end of the experiment. In trial 1, an acute chlorine spike occurred just prior to pathogen challenge (week 7) resulting in substantial mortality among treatment groups. Interestingly, fish fed the IS feed had significantly lower mortality (36.7%) than fish fed the control feed (67%). Vaccinated fish had significantly higher antibody titers than the control fish at week 2 through 7 in trial 1. In trial 2, antibody titers for all vaccinated fish were significantly greater than controls at week 4, but at weeks 6 and 8 the titers of B.17 vaccinated fish were not significantly different from controls. However, average titers for ILM vaccinated were significantly greater than control fish at weeks 6 and 8. Cumulative percent mortality (CPM) in B.17 and ILM vaccinated groups was significantly lower than control groups at the point where CPM reached 60% (mid-way through outbreak), but by the end of the challenge (28. days) ILM vaccinated fish had significantly lower CPM than either control or B.17 vaccinated fish. When comparing dietary effects, CPM was not significantly different but RPS values for fish fed the BioPro IS feed were consistently elevated over groups fed the control diet regardless of the vaccine formulation administered. This study demonstrates increased efficacy of the ILM vaccine in rainbow trout, and provides evidence that a commercial "health enhancing" diet can provide benefits in response to an acute stress event and may contribute to increased vaccine performance. Statement of relevance: This manuscript addresses an important and very practical problem in aquaculture. Coldwater disease is a major disease affecting salmonid aquaculture around the world. There is no approved vaccine available in the US. This manuscript reports the beneficial effects of feeding commercial immunostimulatory functional feeds on the efficacy of two formulations of a coldwater disease vaccine. The results presented here are highly relevant to the development of aquaculture and finding sustainable and non-antibiotic based aquatic animal health management strategies. This study will contribute towards coldwater disease management and identifies potential benefits of commercial functional feeds commonly used in the aquaculture industry. © 2015 Elsevier B.V.

Feeding and digestion has been and continues to be extensively studied for both fundamental and applied purposes, in a range of species from all animal groups. The current proposal represents a novel area of research that offers a new integrative perspective on the otherwise well studied phenomenon of digestion. It also provides a previously unforeseen mechanism for improving the conversion of food-to-growth within the globally important aquaculture of trout and salmon. The potential for commercial application has generated an industrial partnership with Skretting, the largest trout feed producer in the UK and worldwide. The proposal stems from our recent discovery in 2008 that a major phenomenon associated with feeding in mammals, the alkaline tide, also occurs in teleost (bony) fish, in which it had not previously been documented. The alkaline tide is a rise in blood bicarbonate (a base) and pH (i.e. more alkaline) lasting several hours following a meal, which results from the need to balance the secretion of acid into the stomach. This carries an energetic cost that we estimate to be between about 5 and 40 % (depending on buffer capacity of the diet) of the energy used by trout to digest a meal. The resulting acid-base disturbance in the blood will also result in a host of physiological consequences including potentially negative effects on respiratory gas exchange, salt and water balance, energy use that will ultimately limit food conversion efficiency and growth rates. In trout one key response to this blood acid-base disturbance is to excrete the excess bicarbonate base into the external water (via the gills), a compensatory process that can last 36 hours. Any treatments that might either lessen the extent of the alkaline tide, or improve the recovery time, could be extremely valuable to the aquaculture industry. This is because such treatments would reduce the energetic costs for the fish (promoting faster growth rates), reduce the economic costs for the fish farmer, and also lessen the impact on increasingly expensive and hard-fought-for marine resources that are currently used to make fishmeal (the primary ingredient in commercial trout food). The project will focus upon the physiological consequences and costs of the alkaline tide in rainbow trout, and specifically how this might influence the biological and economic efficiency of growth in aquaculture conditions. By understanding the physiological implications of the alkaline tide, and how they are affected by environmental and dietary variables, we should be able to understand how this varies in nature (with fishing feeding naturally on diets with very different buffer capacity), and also how to minimise the energetic costs for fish within aquaculture. We aim to study how the temperature and chemistry of freshwater the fish live in can influence their response and recovery time for the alkaline tide. We will also manipulate the diet to see if we can minimise the need for the fish to secrete acid in its stomach and minimising the alkaline tide, thus saving energy and optimising fish growth. We will investigate these phenomena using experimental physiology under laboratory conditions at Exeter, as well as carrying out commercial-scale feeding trials at Skrettings under conditions similar to aquaculture, using novel feeds designed by Skrettings Aquaculture Research Centre in Stavanger, Norway.
