NEW SAMPLING FOR SECUREFISH

08 April 2021

Julie and Charlotte had the great pleasure to collaborate with the very experienced fishermen from Argelès sur Mer. Lots of soles, anglerfish and hakes ! What a productive day! Thank you Olivier and Carola from Argelès!

OUR PROJECT

CONTEXT - Preserving marine ecosystems is a crucial priority as they support the livelihood and well-being of millions of its citizens (human food provisioning, water purification, disease regulation, cultural values etc). Despite their importance, these ecosystems and their food chains are nowadays jeopardized by numerous environmental alterations, such as climate change, overfishing, invasive species, species extinction, and habitat fragmentation.

OBJECTIVES - The METRODIVER project and its research team participate actively to the international effort for marine ecosystem preservation. More specifically, this project aims to investigates how to efficiently preserve and restore marine food webs. It will notably determine the effects of protection strategies such as marine protected areas on marine food webs. Beyond this first objective, the project will also determine if these effects allows better results in terms of ecosystem services. Its conclusions will directly help local and international authorities to build up better conservation strategies. 

PRACTICALLY - Combining a multi-level approach (community, population, microbiome), cutting-edge techniques and a large scale analysis (10 European MPAs), the METRODIVER project aims to answer three pivotal questions: What are the effects of MPAs on the trophic diversity and food web functioning? How do these effects mediate ecosystem services (e.g. productivity) and animal health (e.g. growth, bodycondition)? To what extent do they contribute to provide healthier food for human societies (e.g. nutritional value of fish flesh)?

COMMUNITY LEVEL

What are the effects of protection on tophic diversity and food web functioning?

Leader: CRIOBE (Fr.)

Methods: Use underwater images to determine trophic diversity and model the effects of marine protection on tropic diversity and food web functioning

Keywords: Undervisual visual census, ECOPATH-ECOMSIM, modelling

POPULATION LEVEL

What are the effects of protection on trophic inputs and outputs?

Leader: GMIT (Ire.) & CRIOBE (FR.)

Methods: Determine the effects of protection on:

  • Trophic input: using otoliths stable isotopes for reconstructing fish diet. Collaboration with Dr. Peter Grønkjær.

  • Trophic output: considering fish flesh nutritive value.


Keywords: Stable isotopes d13C d51N, otoliths, vitamins, fatty acids, minerals

MICROBIOME LEVEL

What are the effects of protection on gut microbiome diversity?

Leader: ULB (Bel.) & CRIOBE (FR.)

Methods: Determine the effects of protection on fish gut microbiome diversity

Keywords: gut bacterial community, 16S, metagenomics

FUNDING

This project has been made possible with the help of 4 European partners that we thank warmly.

BIODIVERSA

BiodivERsA is a network of national and regional funding organisations promoting pan-European research on biodiversity and ecosystem services, and offering innovative opportunities for the conservation and sustainable management of biodiversity. BiodivERsA is funded under the Horizon 2020 ERA-NET COFUND scheme.

AGENCE NATIONALE DE LA RECHERCHE

The National Research Agency (ANR) is a French public administrative establishment, placed under the supervision of the Ministry of Higher Education, Research and Innovation. The Agency implements the funding of research projects, for public operators in cooperation with each other or with companies.

ENVIRONMENTAL PROTECTION AGENCY

GMIT’s involvement is funded under the EPA Research Programme 2014-2020. The EPA Research Programme is a Government of Ireland initiative funded by the Department of the Environment, Climate and Communications. It is administered by the Environmental Protection Agency, which has the statutory function of co-ordinating and promoting environmental research.

FONDS DE LA RECHERCHE SCIENTIFIQUE

The purpose of the Fund for Scientific Research (F.R.S.–FNRS) is to develop fundamental scientific research within the framework of initiatives presented by researchers. It encourages the production and development of knowledge by both supporting individual researchers, and also by financing research programmes conducted in the laboratories and facilities mostly located in the universities of the Wallonia-Brussels Federation.

OUTPUTS

The first results of the study are expected by the end of 2021
