Sustainable fishing and innovation can improve impacts

The National Agency for Fisheries and Aquaculture, ANPA, is the body responsible for the management of fisheries and aquaculture in Romania. It develops a national strategy for the sector and the regulations to implement it. The Agency is also responsible for defining and implementing a policy on the conservation of living aquatic resources and for the organisation of the market for wild-caught and farmed products. Mr Marian Lixandru, President of ANPA, discusses here Romania’s plans for the sector regarding climate change, the pandemic, and marine aquaculture.
Producing food requires huge resources but an estimated one seventh of the resulting products are lost before they are consumed, and in the case of fish and seafood as much as one third! Whether spoiled, destroyed or carelessly thrown away – losses on the way from origin to plate are high. New strategies are now being developed to reduce or, better still, to avoid food waste and losses altogether.

During the catching and processing of fish and seafood considerable amounts of waste occur. Some of it, roughly estimated at around 17%, is “disposed of” at sea immediately after the catch. About twice as much is lost during processing on land. And then there are also losses that occur during transport, at individual stages of trade, in the catering trade, or in consumers’ homes. A definition of the Food and Agriculture Organisation (FAO) is often used to distinguish between “food losses” and “food waste”.
Sursan Su Urunleri AS, a fish production company based in Turkey, became one of the first companies awarded Aquaculture Stewardship Council (ACS) certification for farmed seabass, seabream and meagre. The two farms operated by Sursan share this accomplishment with Nireus, a Greek farm which received ACS certification at the same time. The certification for all four farms were carried out by independent Conformity Assessment Body Acoura. The certification guarantees the products are produced in a socially and environmentally sustainable manner. Since receiving certification on June 5, 2019, producers of seabass and seabream have responded enthusiastically with a strong demand for ACS certified products. High demand for ACS certified products has driven more farms to schedule audits to the new standard. Farms in Turkey, Greece, Spain, Croatia and Albania have all undergone audits since Sursan received ACS certification.
Omega-3 fatty acids from microalgae instead of fish oil
Fish oil is not available in sufficient quantities to meet the growing needs of the aquaculture and nutraceutical industries. Although essential omega-3 fatty acids are also to be found in microalgae, production capacity has so far been low. That is now changing, however, and developments in this field are making rapid progress. The first feeds for aquaculture with omega-3 fatty acids from algae are now available on the market.
Human beings – like fish – have to consume a certain amount of essential, long-chain, polyunsaturated fatty acids with their food every day in order to stay healthy and develop "normally". The omega-3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are particularly important. These are not produced in the body but must be obtained from food. Hundreds of scientific studies have revealed that EPA and DHA are of huge importance for the development and health of the brain, eyes and cardiovascular system.
With regard to their use in animal and aquaculture feed both of these fatty acids have up to now been obtained almost exclusively from marine fish oil sources. However, fish oil supply is limited because the available wild fish catches cannot be increased at will and they are also used more for direct human consumption. Global fish oil production is currently stagnant at around one million tonnes a year and is indeed tending to decline. This situation is already endangering the growth of aquaculture which uses almost three-quarters of worldwide fish oil production. Significant increases are not to be expected for the time being despite the fact that fish oil producers now also gain raw materials from previously unused reserves such as slaughterhouse waste and by-catches from the fishing sector which were previously discarded at sea immediately after the catch. It is estimated that 15 to 20 million tonnes more raw material could be taken from these sources each year. Hopes now also rest on the stocks of mesopelagic fish species which live in the oceans at depths of between 200 and 1,000 metres. Scientists have estimated their biomass at 10,000 million tonnes. If this is correct it would be by far the largest known fish resource. Access to these fish, however (they live at the upper limit of the deep sea) poses enormous risks to oceanic ecosystems because we still know far too little about the mesopelagic fish world to be able to use it sustainably.
Cooperation on marine research and innovation in the Black Sea region is receiving a strong boost with the adoption of the Black Sea Strategic Research and Innovation Agenda (SRIA). The agenda, prepared by researchers and scientists from the region’s major marine research institutes and scientific bodies, aims to make the Black Sea more productive, healthy, resilient, sustainable and better-valued by 2030. It will be the research and innovation pillar of the Common Maritime Agenda for the Black Sea, to be agreed at the end of May.

St. Petersburg, the “Venice of the North”, hosted the second edition of the Global Fishery Forum and Seafood Expo Russia on 13-15 September 2018. The event centered on what to expect from the global fisheries industry and markets in the coming decades.
The forum brought together more than 1 100 business leaders, members of international food and fisheries organizations, specialized ministries, international seafood companies and fisheries representatives from 42 countries, including Canada, China, Denmark, the Faroe Islands, Germany, Iceland, Italy, Japan, Morocco, Norway, and Turkey.
Asia strongly represented at aquaculture session
The session “Aquaculture production and development forecast by 2050” focused on the discussions of the state of the global aquaculture sector, its future growth, and environmental control and safety. Moderated by Ekaterina Tribilustova, Eurofish International Organisation, the session hosted experts from specialized agencies, ministries, sectorial organisations and unions from 8 countries, including the Federal Agency for Fisheries of Russia, the Union of Sturgeon Breeders of Russia, China’s Union of Seafood Processing Enterprises, Ministry of Agriculture and Forestry of Turkey, the Ministry of Agricultural Development of Islamic Republic of Iran and Shilat Organization for Fisheries and Fish Farming of Iran, and the National Institute of Research and Development of fisheries sector in the Republic of Korea.
At present, the aquaculture industry produces over 45% of fish and seafood products consumed globally, while the share of fish products is 53%, according to the FAO. At the same time, the global population has never consumed as much fish as now. Since 1961, the growth rates of fish consumption in the world have been two times higher than the population growth, while the production growth rates have been declining. It is expected that even growing at a slower rate the aquaculture sector can eliminate the gap between growing demand and declining resources playing a major role in providing the world population with the proteins they need. The aquaculture sector in particular has an especially important role in improving food nutrition and fighting hunger.
