      • Thursday 11th October a.m. | Room 2

      • Organised by: Pôle Mer Bretagne Atlantique

        Location: Room 2

        (Session in English)

         

        The session will be the opportunity to highlight and discuss different actions and projects led at regional, national and European levels regarding domestication of current or new species, of vegetal and animal origin. Several sessions will be organised regarding the selection of the species to be produced regarding knowhow, technologies and processes, economic and management issues,  markets, territorial specificities…, in monospecific and/or co-cultured schemes, and Integrated Multi-Trophic Aquaculture. An overview of existing onshore and offshore activities will be also of interest, and the opportunity of new activities linked to marine energies, platforms. Feeding represents a big challenge for the different productions: new sources of proteins, lipids from algae, insects, etc.; natural medication; animal well-being, etc. The participation of European and international experts will enable nice and constructive exchanges regarding experimentations in other territories.

        Integrated Multi-Trophic Aquaculture (IMTA): a flexible approach to responsible aquaculture, valuing ecosystem services, fitting within a circular economy framework, and compatible with the management of marine protected areas

         

        In tomorrow food production systems, aquaculture will have an increasing share. However, the Blue Revolution needs to become the greener Turquoise Revolution by developing innovative technologies and practices with increased environmental sustainability, economic stability and societal acceptability.    

        With Integrated Multi-Trophic Aquaculture (IMTA), farmers cultivate species from different trophic levels with complementary ecosystem functions in proximity. They combine fed with extractive species to take advantage of synergistic interactions among them while biomitigation operates within a circular economy approach. Because different nutrients need to be recaptured, different spatial and temporal strategies should be designed. This means that entire bays/regions can be units of IMTA management, within an Integrated Coastal Area Management (ICAM) strategy.

        The IMTA concept is highly flexible and ever evolving. It has many variations adaptable to open-water/land-based, marine/freshwater, and temperate/tropical systems; it, consequently, cannot be reduced to a short definition. It is also a practice compatible with the objectives and governance of marine protected areas.

        To bestow IMTA its full value, extractive species need to be valued for not only their biomass/food trading values, but also for the ecosystem services and the increase in consumer trust and societal/political license to operate they provide. The value of the ecosystem services should be used as financial/regulatory incentive tools (nutrient trading credits). The IMTA multi-crop diversification approach could be an economic risk mitigation/management option to address pending climate change/coastal acidification impacts

        ALMÅS Karl Andreas, Ph.D, Special Advisor, SINTEF Ocean, and Board Chairman of Norwegian Center of Expertise Aquatech Cluster

        Development the Norwegian aquaculture industry through cluster cooperation.

         

        The NCE Aquatech Cluster is one of the largest aquaculture clusters globally. It has more than 120 Norwegian partners representing approximately 16.500 employees worldwide and an annual turnover of 60 billion NOK (2017). The cluster represents the supplier industry (80 %), large fish farmers, fish processing industry and institutions for technological based research and education. The main goal is to increase the value creation in the Norwegian aquaculture supplier industry. The cluster is a part of the Norwegian Innovation Cluster Programme and the focus area is sustainable aquaculture food production for international markets.

        The main industrial activities will be described, and the operational experiences of the NCE Aquatech Cluster will be discussed during the presentation.

        Part 1-2 : Domestication of news species, and  genetics monitoring

        11:00

        LAGUERRE Hélène, Agrocampus-Ouest, in chrage of aquaculture-innovation projects and LUTHRINGER Rémy, in charge of Algi and innovation projects

        Domestication of news species, candidates for IMTA systems

         

        To develop efficient IMTA systems, the choice of species is crucial. Domestication of news species is an essential step for innovation in aquaculture, and it opens up new potentialities.

        Agrocampus Ouest (site of Beg-Meil) is a partner for innovative aquaculture, by developing collaborative experimental projects, with all the stakeholders involved in aquaculture fields.

        In that way, different projects are conducted : MARBiotech, which aims to control the life cycle of the marine lungworm Arenicola marina (project leaded by Hemarina), HOLOFARM, to create a new aquaculture based on the sea cucumbers breeding, and POLISTR, to develop innovation in seaweed cultivation.

         

        Partnership : Hemarina, Station Biologique de Roscoff, UBO – LBCM, CRC Bretagne Nord, CRC Bretagne Sud, CRPMEM Bretagne, AQUA B, MNHN Station de Concarneau, Ferme marine de Noirmoutier…

        HUCHETTE Sylvain, France Haliotis

        Sea-based abalone aquaculture: high value for seaweed and the environment

        Over the past 15 years, France Haliotis has developed a new low trophic aquaculture model using European abalone, Haliotis tuberculata. Abalones are among the most valued seafood in the world. They are herbivorous gastropods feeding on various seaweed that are abundant on western Brittany shores. France Haliotis has developed unique techniques to:

        • culture seaweeds of improved nutritional value to feed abalone juveniles and adults,
        • manage local seaweed stocks to guarantee sustainable harvest and maintain biodiversity over the years,
        • improve feed conversion performances through seasonal nutrition planning and genetic selection.

        ALLAL François, PhD in aquaculture genetics and genomics, MARBEC, Ifremer-CNRS-IRD-UM, Palavas-les-Flots, France.

        « GeneSea: Fish and Chips!»

        Single nucleotide polymorphism chips (or SNP arrays) are major tools for evaluation of genetic diversity of species. Here, we report the first development of a high quality 56,730 SNPs array for European sea bass (Dicentrarchus labrax), DlabCHIP Axiom Affymetrix®, that will become commercially available in 2018. In this presentation, after a quick overview of this novel tool and its particular design, I will expose the expected impact of such innovation, to describe and manage the inbreeding, the genetic diversity of farmed or wild populations and first of all for further genomic-based improvement of the sustainability and performances of livestock populations.
