ABSTRACT

 

Marine habitats provide various essential functional roles for teleosts. Therefore, the consideration of this functional complementarity through a landscape approach of management measures is essential. Nursery habitats are essential to teleosts’ life cycle and their populations’ renewal yet they are fragile and their conservation represents an overriding stake. Among those nursery habitats, the shallow heterogeneous rocky bottoms, sheltering Diplodus juveniles, remain poorly known among managers.

Thus, the aims of this study were, on one hand, locating and mapping this habitat along the whole Mediterranean French coast and, on the other hand, assessing its disponibility, spatial distribution and degree of consideration in management measures zoning.

Along 2705 km of Mediterranean French coast, we mapped 4989 nurseries, totalling an occurrence on less than 10 % of the coast line and reflecting a low disponibility of the nursery habitat. Moreover, its spatial distribution hilighted an heterogeneous pattern, varying from 3.7 % to 12.9 % depending on the zone, but also depending on the level of protection of the considered coastline. The influence of protection level on the habitat disponibility varied, depending on the zone and its specificities, but demonstrated a global absence of consideration of this essential habitat in the management zoning. Our results hiligthed this habitat suffers from precariousness due to its low disponibility and its absence of consideration by management zoning along with its intrinsic fragility and coastal location.

 

By releasing those results and the map database, this work attempts to promote a better consideration of this habitat in the management measures and thus, to optimise fishing resources conservation efforts.

JUVar – Evaluation of juvenile grouper populations in shallow coastal habitats of the Var coast (France).

Lien

Monfort T., Nunez L., Cheminée A.

Abstract

On the Mediterranean coast, following on from the monitoring of grouper population dynamics carried out by the Grouper Study Group (GEM), the Office Français de la Biodiversité (OFB) provided financial support for the JUVar project, which also received technical and logistical support from the Communauté des communes du Golfe de St-Tropez-Service Espaces maritimes during the field campaign in October/November 2022. The JUVar project is managed by Septentrion Environnement. It lasted 6 months, from November 2022 to April 2023. The objectives of this study were to inventory (1) the assemblages of juvenile fish, with (2) enhanced sampling to quantify the presence of juvenile groupers (Epinephelus spp.) and (3) describe the micro-habitat preferences of the latter, using the Var coastline as a workshop site. This project complements existing data on grouper populations along the Mediterranean coast (Condini et al., 2018), and more specifically for the early life stages of this protected species. The presence of Brown meagre (Sciaena umbra) was also noted, as they represent one of the Mediterranean’s emblematic species protected by a 4th moratorium since 2013.

Abstract

The MedHab project is led by Septentrion Environnement. Its initial duration of 3 years was extended to 4 years following the health crisis linked to covid 19, from 2019 to 2022. This project focuses on essential habitats (spawning grounds and nurseries) for fish in shallow coastal waters. Structured in work packages (WP), it aims to produce 1) a summary of knowledge concerning these essential habitats in the Mediterranean; 2) for the entire Mediterranean coastline, a location and quantification of “shallow heterogeneous rocky ” type nurseries and assessment of the extent to which they are taken into account in existing management measures; 3) for at least 3 control areas with MPAs, a comparison with two other types of nursery habitats (seagrass beds and macro-algae forests); and 4) sharing the results with managers in order to optimise coastal zone management strategies.

POLARIS – Methodological note

Lien

Estaque T.

This methodological note is intended primarily for decision-makers and managers of Mediterranean marine areas for which scuba diving is a tool for monitoring the environment through participatory science (standardized observation protocols, training of observers, data processing). It may also be useful to any institution interested in the use of observation platforms such as POLARIS to feed territory management strategies at different scales of action. Finally, this note will guide structures wishing to use citizen science in scuba diving by detailing various scientific and technical aspects (monitoring protocols, logistics, data processing and transfer, animation, training, etc.).

Restitution of data collected as part of POLARIS environmental monitoring

Lien

Barth L., Gatti G.

The primary intention of this document is to explore the occurrence data collected by volunteer citizen divers, as part of the environmental monitoring proposed by POLARIS. Descriptive analyzes of these data provide an overview of the spatial distribution of target species of scientific and management interest. They are intended to supplement scientific knowledge and must be linked to more specific studies on the territory and on the species presented here. The results are presented from a management point of view, since the POLARIS program aims in particular to help guide measures for the sustainable management of the marine environment. This document presents the results obtained from the observations made in 2020. Comparisons with observations made in 2018 and 2019 were made, so as to initiate a temporal analysis of the data.

Final report of the foreshadowing year of the PERC²ES project – Citizen PERceptions of Environmental and Societal Changes

Lien

Gatti G., Scotto d’Apollonia L., Dosias-Perla D., Vouriot P., Barth, L.

The PERC²ES project aims to integrate the social dimension into the management of the coastal marine environment, through the experimentation of a participatory approach between local stakeholders. 2020 was a year of prefiguration for engaging in a multidisciplinary approach based on the specific tools of Participatory Action Research (RAP): testing participatory methods for co-construction, co-definition of objectives and actions to be taken, up to co-analysis and discussion of results by associating a diversity of participants (scientists, citizens, coastal actors, land managers, institutions). In its foreshadowing year, the field of action was the Marseille coast, a territory rich in natural resources, very popular among tourists, highly urbanized and subject to numerous anthropogenic pressures. The man-natural environment relationship is very close here, whether for professional or leisure activities; it is therefore obvious that for the sustainable management of this coastline, the environmental and social dimensions are inseparable. Since 2015, this coastline has been the subject of an action program led by the Métropole of Aix Marseille Provence and the City of Marseille: the Bay Contract. This program aims to preserve the littoral and the coastal environments while supporting the harmonious development of human activities. This is the ideal context for the implementation of the PERC²ES project.

Presentation of results from data collected through the participatory science platform POLARIS, as part of the CIGESMED research program

Lien

Gatti G., Barth L.

The participatory science program CIGESMED for divers is dedicated to the observation of coralligenous reefs. Volunteer divers contributed to collecting 89 observations within the Calanques National Park over a three-year period (2016-2018). With the data collected, we were able to characterize the coralligenous reefs, to observe the distribution of the organisms and of the pressures that threaten them. We were thus able to draw up the reference state, to which refer for the monitoring still in progress by recreational divers. We choose here to present the results from a management point of view since our program aims in particular to help developing guide measures in favor of the sustainable management of the marine environment. We will also discuss future reflections and analyzes drawn from the data collected.

POLARIS – Environnemental monitoring

Lien

Barth L.

At the interface of different activities, POLARIS is a field platform for observing the marine environment. It contributes to data collection for scientific actions and raises awareness among citizens about environmental diving.

The purpose of the environmental monitoring is to warn against potential changes in the marine environment through long-term, multi-year monitoring. The aim here is to monitor the presence or absence of elements providing information on the state of health of the marine environment and those which could affect it.
