1 Carp in the FAO program Aquatic genetic resources for food and agriculture Zsigmond Jeney and Matthias Halwart NAIK-HAKI Research Institute for Fisheries and Aquaculture Fishery & Aquaculture Policy and Resources Division (FIA), FAO 4th International Carp Conference September 2017 Zagreb, Croatia

2 Carp in the FAO program Aquatic genetic resources for food and agriculture Draft State of the World's Aquatic Genetic Resources for Food and Agriculture Report: It can also be found on this website - For this presentation and the first draft of SoW AqGR (April 2016), only 47 reports were analysed - Today, 92 national reports are available and being analysed, so expect updates soon!

3 Content 1. Aquatic Genetic Resources for Food and Agriculture. Towards a State of the World Report. Based on the presentation by Mr. Jiansan Jia at the 40th Anniversary National Scientific Conference on Fisheries & Aquaculture. Held at NAIK-HAKI, Szarvas, Hungary, June 15, Common carp in the SoW of Aquatic Genetic resources Based on the SoW of Aquatic Genetic Resources (Draft of April 2016)

4 Introduction Fisheries and aquaculture are crucial for food security and poverty alleviation. Capture fisheries: about 5,000 species. Aquaculture: more than 575 species of finfish, molluscs, crustaceans, amphibians/reptiles, aquatic invertebrates, algae

5 Introduction The contribution of aquaculture to world food fish production increased from 3.9% in 1970 to more than 50% in 2014 with growth expected to continue. Aquatic genetic resources are of key importance for the further genetic improvement of fish strains to achieve sustainable development of aquaculture

6 Global fisheries and aquaculture production (tonnes)

7 Constraints Capitalizing on the enormous potential of aquatic genetic resources requires overcoming specific constraints: 1. Lack of information regarding the genetic characteristics, performance, location and accessibility of aquatic genetic resources and regarding threats to their survival. 2. Inadequate national programmes and information systems for aquatic genetic resources. 3. Lack of a global policy and management approach to aquatic genetic resources.

8 Pathway Lack of data/information and inadequate standardization Poor understanding of the status and trends of Aquatic Genetic Resources Genetic information will be increasingly important to support sustainable aquaculture and fisheries Improvements in knowledge of the status and trends of farmed aquatic species and their wild relatives More comprehensive policy, planning and management of these essential resources.

9 Goal The challenge is to improve information on the status and trends of many aquatic species which will facilitate maintaining and further developing a broad genetic base for the future

10 CGRFA and AqGR At its 11 th Regular Session, the Commission agreed that improving the collection and sharing of information on aquatic genetic resources is of high priority. The Commission included the preparation of The State of the World s Aquatic Genetic Resources for Food and Agriculture (SoW AqGR) into its Multi-Year Programme of Work (MYPOW). Main outputs and milestones Presentation of The State of the World s Aquatic Genetic Resources for Food and Agriculture based on a country driven process (2017). Development of elements related to the Code of Conduct for Responsible Fisheries aimed to maintain a broad genetic basis to ensure sustainable use and conservation of AqGR (2019).

11 Work of the AqGR team Use and exchange of genetic resources Background Study Paper no. 45 The use and exchange of AqGR for Food and Agriculture Background Study Paper no. 55 Climate Change and Aquatic Genetic Resources for Food and Agriculture: State of Knowledge, Risks and Opportunities FAO International Expert Workshop Improving the Information Base for Aquatic Genetic Resources for The State of the World's Aquatic Genetic Resources.

12 CGRFA 14 critical for AqGR Decided on scope: Farmed aquatic species and their wild relatives within national jurisdiction Stressed that work towards the preparation of the SoW AqGR should link to and build on the FAO Code of Conduct for Responsible Fisheries. Agreed on the structure and contents of the SoW AqGR Requested FAO to identify options for strengthening the ongoing collection and analysis of country-level data and information on fisheries and aquaculture by including information on aquatic genetic resources. Called on countries to participate in the process by preparing national reports on aquatic genetic resources and to strengthen related information systems.

13 CGRFA 15 move on with AqGR Requested FAO to also consider information contained in country reports prepared for The State of the World s Biodiversity for Food and Agriculture Noted the need to strengthen existing information systems and requested FAO to identify opportunities to strengthen them at the regional and global levels Invited relevant international and regional organizations with a recognized mandate and competence to contribute to the preparation of the report, including through providing reports to FAO Agreed to establish the Ad Hoc Intergovernmental Technical Working Group on Aquatic Genetic Resources for Food and Agriculture specifically with the task to guide the preparation of and review the report.

18 THEMATIC BACKGROUND STUDIES 1. Incorporating genetic diversity and indicators into regular statistics and monitoring of farmed aquatic species and their wild relatives 2. Biotechnology and genomics in aquaculture 3. Genetic resources for farmed seaweeds and freshwater macrophytes (*divided into two separate reports) 4. Genetic resources of microorganisms of current and potential use in aquaculture

19 Carp in the FAO program Aquatic genetic resources for food and agriculture Select and analyse the relevant sections for carp Describe the issues around carp What can the SoW tell us about the global situation of carp genetic resources around the world?

20 Production of freshwater fish (2010) The majority of production volume is based on the lower trophic level species. This underscores the contribution of these species to global food security and their relatively efficient production of high quality protein relative to other livestock systems.

21 Carp is cultured in wide diversity of aquaculture systems

22 Top 10 aquatic species being farmed The most commonly reported species being farmed was common carp, C. carpio, and it was introduced into most of the countries where it is farmed. In fact, many of the commonly farmed species are not native to many (most) of the countries that farm them

23 Genetic technologies for improving farmed types and indicative responses in farmed aquatic species. Carp responds well to genetic imporvement methods

24 Example: Relationships of carp lines using microsatellite markers - A basal and distinct phylogenetic position of the Asian population has been proved. - Among European populations, wild (natural) lines were clearly separated form cultured ones and from each other, too. Amur scaly (Asian wild line) Danube scaly (European Tisza scaly wild lines) cultured carp lines kept in gene bank - The cultured lines in Hungary showed closer genetic relationship to each other according their known breeding history. - Inbreeding effects at a certain extent could be observed as a result of the loss of heterozygosity. koi outgroup

27 Increased wealth and demand for fish Over the last two decades ( ) there has been a substantial increase in trade in many aquaculture products based on both low- and high-value species. New markets have emerged in developed, transitioning and developing countries. Aquaculture is now a significant contributor to the international trade in fishery commodities. This is dominated by high-value species such as salmon, seabass, seabream, shrimp and prawns, bivalves and other molluscs but also includes lowervalue species such as tilapia, catfish (including Pangasius) and carps. These low-value species are traded in large quantities within and between countries in two main regions (Asia and South America) and are increasingly finding markets in other regions (e.g. Pangasius, tilapia) (SOFIA, 2014).

28 Consumer preferences and the relevance to genetic characteristics of farmed-type AqGR

29 Use of non-native species in fisheries and aquaculture Top 10 species exchanged by countries, includes both import and export. Production from non-native species was shown to be increasing in many areas for both fisheries and aquaculture. As expected the most common form of genetic material exchanged with another country was living specimens.

30 Introductions of parasites and pathogens Species transferred between regions for aquaculture purposes have also resulted in the introduction of diseases, which have severely impacted aquaculture production or stocks of wild relatives: Various carp viruses have been transferred through movements of fish for aquaculture as well as for the aquarium trade (e.g. Koi Herpes Virus, CEV) Possible risks connected to the relatively easy transportation of eggs

32 Indirect effects of climate change on AqGR through impacts on ecosystems Water temperature rise will enable species to extend their ranges in temperate areas and encourage the establishment of invasive species.

33 Top 10 species for which habitat was reported to be declining and status on IUCN Red List (NA = not assessed; LC = Least Concern; DD = data deficient to assess; V = Vulnerable) Table shows the top 10 wild relatives whose populations and habitat were decreasing. A comparison with the IUCN Red List shows that only two of these species are listed as vulnerable, several are of least concern and the majority haven t been assessed.

34 Impacts of purposeful stocking Differing strategies for management of inland waters for fisheries in developed and developing countries

35 Ex-situ conservation of AqGR Because of the short history of domestication, breeding programmes and related research for most farmed aquatic organisms, the free-living populations of their wild and feral relatives and of other potentially farmable aquatic species have high importance as genetic resources. Many of these free-living populations, especially in freshwaters, are among the world s most seriously threatened biodiversity; for example, the wild genetic resources of farmed carps and tilapias.

36 Carp genetic resources in Central and Eastern Europe They include wild forms of carp as well.

37 Catalogue of carp breeds of the countries of Central and Eastern Europe. The most recent inventory of carp strains. (by Bogeruk, 2008 in frame of the EUROCARP project) Plan to publish on internet by FAO All together 60 national strains and 25 foreign strains described in 7 major carp producing countries.

40 Final thoughts It is too early to give definite conclusions on the state of genetic resources of carp not all important producer countries had reported. Findings on carp, from point of view of Aquatic genetic resources for Food and Agriculture. Produced in different aquaculture systems, in large volumes, worldwide; The most commonly cultured species, often used for exchange, in many places is not native; Original genetic resources in wild are in danger; Responds well to selective breeding and crossbreeding methods; Once the final SoW AqGR is released, the situation will become clearer
