FEEDBACK ON THE 1st WORKSHOP October 4, 2019 - La Londe-les-Maures
Biological and toxicological contamination of cetaceans in the Pelagos Sanctuary : assessment, origin, monitoring and mitigation
2° workshop - February 19, 2020Diano Marina (IM), ITALY
Léa JURET - GIS3M
WHAT HAPPENED DURING THIS WORKSHOP :
19 participantsAssociations (GIS3M, GECEM, Souffleurs d’Ecume, WWF)Marine protected areas (Port-Cros National Park & Pelagos Sanctuary)Institutions (Maritime prefecture of the Mediterranean)Research establishments (VetAgroSup, CReDiMa, Sienna University, La Rochelle University & PELAGIS Observatory)
6 talksState-of-the-art on chemical and biological pollution affecting cetaceans in the Pelagos Sanctuary(Julie Jourdan-GECEM)Results of diagnostic activities on stranded cetaceans, Ligurian coastline, 2017-2019(Carla Grattarola-CReDiMa)Historical and emergent contamination of the large cetacean in Pelagos sanctuary(Denis Ody-WWF France)Cetacean’s chemical contamination in the Pelagos Sanctuary: issues and methodology(Philippe Berny-Vetagro Sup)The Impact of Microplastics in the Pelagos Sanctuary and on Filter-feeding Megafauna(Maria Cristina Fossi-University of Siena)Pollutants monitoring in marine mammals off the French coasts(Paula Mendez-Fernandez & Florence Caurant-University of La Rochelle, Observatory PELAGIS)
Discussions around 3 issues Mitigation measuresMonitoring methodsResearch & conservation priorities
Drug products
Little knowledgeFew studies
Chemical contaminants
Historical Recent
Reduce the frequency of studies and the number of individuals sampled
Continue the phthalates study on
3-year follow-ups every 10 years
Biological contaminants
Routine long-term monitoring
Salmonella, Herpesvirus, Brucella ceti,
DMV, Toxoplasma
Deadliest pathogens for
cetaceans
Healthproblems in
humans
WHAT CONTAMINANTS SHOULD BE PRIORIZED ?
Parasites
RESEARCH & CONSERVATION PRIORITIES
SHOULD WE FOCUS STUDIES ON SOURCES OF POLLUTION AND PRIORITY AREAS ?
Aspect rather political, out of our field of action and our possibilities to act
At our scale : act at the level of MPAs (monitoring…)
RESEARCH & CONSERVATION PRIORITIES
CETACEANS : GOOD MONITORING TOOLS ?
☑ bioindicators for contaminant study
WHICH SPECIES TO TARGET ?
WHICH METHOD(S) SHOULD BE PREFERRED :STRANDINGS, BIOPSIES OR BOTH ?
Coastal specie more exposed to pollutants
Data from strandings Data from biopsies
- - Contaminants degradation ++ Mediterranean sea Take available stranding data (additional data)Sample “healthy” population
MONITORING METHODS
THE PELAGOS SANCTUARY AS A STUDY PLACE ?
Constraint for the biopsiesNew prefectoral decree to regulate the approach of cetaceans to 100 m
(applies also to scientists)
Adapt the monitoring to minimize the disruption(How many individuals do we need ? How often?)
Give priority to monitoring
outside marine protected areas
HARMONIZE MONITORING
☑ Combine protocols nationally and internationally
MONITORING METHODS
TWO MEANS OF ACTION
➢ Develop and promote knowledge of cetacean
contamination to raise awareness and involve citizens.
➢ Commitments of member municipalities to reduce
pollution
MITIGATION MEASURES
