1 INSTITUTO PORTUGUÊS DO MAR E DA ATMOSFERA (IPMA, I.P.) Aquaculture, Bivalve molluscs and Seafood safety Maria Leonor Nunes Head of Aquaculture and Upgrading Divison

2 WHO ARE WE? IPMA, I.P. is a governmental research institution from the Portuguese Ministry of Agriculture and Sea MISSION: To promote and coordinate the research, technological development, innovation and public services in the field of fisheries, aquaculture, seafood quality, marine environment, meteorology, aeronautical meteorology, seismology, climate and geomagnetism

3 IPMA/SEA WHO ARE WE? Lisbon Algés Division of Marine Geology and Marine Georesources (DivGM) Division of Environmental Oceanography and Bioprospection (DivOA) Division of Fisheries Modelling and Management (DIvRP) Division of Aquaculture and Upgrading of Fishery and Farmed Products (DivAV) Algarve Olhão Tavira

4 DivAV WHO ARE WE? I. Aquaculture Production biology Breeding and genetics Nutrition and feed technology Species diversity Pathology/diseases II. Seafood Upgrading/Quality and safety Seafood quality and safety Seafood preservation Seafood processing Seafood traceability III. Marine Biotechnology Fish protein hydrolysates Fish peptones Other molecules (e.g. Squalene, DHA from microalgae)

5 I. Aquaculture EARTH PONDS (7 ha) The main objectives are to: DEVELOP knowledge STUDY the mitigation of aquaculture impacts COLLABORATE in decision support models SUPPORT farmers and administration SHELLFISH PILOT PLANT (13 ha) OFFSHORE RESEARCH STATION

6 I. Aquaculture OLHÃO PILOT PLANT (7 ha) Broodstock and larval rearing Broodstock management; Sperm and egg quality; Development of rearing protocols for new species; Optimization of feeding protocols; Larval nutrition requirements and digestive physiology Earth ponds Potential growth of new species; Assessment of new methodologies for disease prevention and treatment; Development and optimization of different rearing strategies; Certification. Off shore facilities Operational factors and support for sea cage aquaculture; Biological and environmental conditions to support farming; Potential growth and handling of fish; Technology transfer to the productive sector

7 I. Aquaculture TAVIRA SHELLFISH PILOT PLANT (13 ha) CLAM Ruditapes decussatus IMPROVE the broodstock conditioning and gamete quality STUDY the reproductive cycle of different geographic populations IMPROVE settlement and metamorphosis synchronisation APPLY/OPTIMIZE a low cost larvae/seed production system DEFINE a genetic basis for reproductive performance of different populations IDENTIFY the genes involved in oocyte maturation and in investment of clams reproduction, as well as markers (mrna or proteins) of clams oocyte quality OYSTERS C. angulataand C. gigas OPTIMIZE the larval and seed culture of C. angulata COMPARE the aquaculture performance of the Portuguese oyster C. angulata and the Japanese oyster C. gigas

8 I. Aquaculture PATHOLOGY OF AQUATIC ANIMALS Research activities Study of diseases in aquaculture and wild species; Prevention and control of major diseases through improved diagnostic techniques and early identification of disease processes; Promoting good practices zoosanitary prophylaxis of holdings; Contribution to the diagnosis and minimization of massive mortalities in wild; Collaboration with seafood industry in order to control zoonotic agents potentially transmitted Skills in the diagnostic area: Histopathology, Virology, Bacteriology, Parasitology, Molecular Biology (PCR - RFLP) National Reference Laboratory (NRL) For Mollusc Diseases Marteliose in flat oyster refuvar ref uvar ref uvar PCR OsHV virus

9 II. Seafood Upgrading The main objectives are to: DEVELOP research and technological innovation SUPPORT the fishing and aquaculture industry ADVICE stakeholders, authorities, fishery and health institutions CONTRIBUTE to a responsible production and consumption of seafood RESPONSIBLE CONSUMPTION

10 II. Seafood upgrading BIVALVE MOLLUSCS SAFETY Classification & monitoring of production and relaying areas. Establish a sampling programme of bivalve molluscs in the production area. Audit the labs that supply services to the producers. Keep the methodologies updated and validated. Participate regularly in intercomparision exercises. Two labs are NRL (national reference labs for bivalve molluscs microbiological quality and for chemical contaminants (toxic elements) in seafood)

11 II. Seafood upgrading SEAFOOD QUALITY AND SAFETY Biopreservation Active packaging Modified atmosphere packaging Combined technologies (hurdletech) Creating the Foods of the future

12 II. Seafood upgrading SEAFOOD QUALITY AND SAFETY Research for the detection, benefits assessment and prevention of risks Contaminants, nutrients, etc Colour, texture, etc. Pathogenics and deteriorative microbiota Microrganisms from aquatic environment and animal/human reservoir Sensorial evaluation Bioaccessibility/vioavailability (in vitro methods) Tools for Risk/benefit assessment Consumer preferences SEA

13 DivAV (Some recent European projects) SEA-ON ON-a- CHIP GOODFISH FreshFish And many others at european and national level

14 DivAV FOR THE FUTURE It will be a pleasure for IPMA, I.P. to collaborate with you in future projects!
