Full textDuring their life cycle, most of the marine coastal fish species use nursery grounds which quality influence their recruitment and then the conservation of their populations. However, the construction of ports impair irremediably fish nursery function of the coastal areas impacted. The ultimate aim of the PhD research was to assess if ports could provide suitable alternative nursery habitats for coastal fish species. Firstly, abundances of the juveniles of four Diplodus species were surveyed in five marinas located along the French Mediterranean coast. This showed that coastal fishes can successfully settle and grow inside these artificialized coastal areas. Moreover, increasing the complexity of port habitats can considerably enhance their suitability for juveniles, especially at the youngest stages. Secondly, body condition, growth rate and metal contamination in the juveniles of two Diplodus species (D. sargus and D. vulgaris) were compared between different ports and natural areas in the Bay of Toulon. Juvenile growth and condition can be equivalent between fish collected from ports and from adjacent natural areas. Contamination levels in fish were low, even in highly polluted areas. Finally, otolith composition in the juveniles of D. sargus and D. vulgaris was investigated in three ports and two natural areas in the Bay of Toulon. None of the port related had systematically higher concentrations in otoliths from Diplodus juveniles collected in ports. Therefore, otolith microchemistry cannot provide a unique and reliable fingerprint discriminating ports and natural areas. Nevertheless, otolith microchemistry could provide an effective natural tag to determine the contribution of ports to adult stocks provided that a library of all potential juvenile habitat fingerprints is established. All these results confirm that ports can be used as alternative nursery habitats by marine coastal fishes. Ecological engineering projects aiming at increasing structural complexity of port habitats seem promising for biodiversity and fish stock conservation

Full textCoastal development modifies shorelines by introducing man-made habitats, which significantly impact coastal biodiversity and ecosystem functioning. Ecological engineering solutions, such as artificial fish habitats (AFH), can help rehabilitate extremely modified areas, including ports, by offering shelter for fish. As a side effect, AFH provide a substrate to benthic invertebrates and macroalgae, that could improve ecosystem functioning. The effects of AFH may also extend beyond ports and modify trophic exchange with adjacent habitats via fish feeding hydrodynamics. This thesis investigates the patterns of distribution of invertebrate biodiversity associated with AFH and explores the exchange of biomass between marinas and adjacent Posidonia oceanica meadows along the French Mediterranean coast where these habitats are often adjacent.The objectives are: (1) evaluating how taxonomic diversity and composition of benthic invertebrates vary with AFH immersion time, (2) understanding how AFH types and environmental context modify benthic assemblages, and (3) exploring the exchanges of organic matter between marinas and adjacent meadows. I focused on Biohut® AFH (ECOCEAN), made of a metal cage filled with oyster shells, attached to docks or under pontoons in harbours and marinas.In chapter 1, I examined the role of immersion time in determining the diversity and composition of invertebrate assemblages colonising AFH in 3 commercial harbours. The findings indicated significant variations in invertebrate composition from 6 to 18 months, with increased abundance, taxonomic richness, and evenness over time. In chapter 2, I focused on the geographical and within-port variability in taxonomic composition and diversity of invertebrates dwelling in AFH. The study revealed differences in taxa composition between 2 large regions, characterised by different nutrient loads and correlations between assemblage composition and chlorophyll-a, a proxy for nutrient concentration. The number of taxa was the highest in the nutrient-enriched region. Additionally, invertebrate assemblages varied according to port habitats where the AFH were placed, possibly due to differences in light availability. In chapter 3, I investigated trophic connectivity between P. oceanica meadows and adjacent marinas at 4 sites where both habitats are present. Two marinas were equipped with AFH and the remaining 2 were not. At the unequipped sites, the δ15N values of the particulate organic matter within the marina were the highest indicating human-derived nutrient enrichment. The values decreased within the meadow, gradually according to the distance. This suggests a spill of nutrients over the portion of the meadow adjacent to the inlet. Fish relied on resources from both the seagrass meadow and the marina, similarly among the 4 sites, however, the trophic niches of fishes (Diplodus spp.) captured within the equipped marina were slightly larger than those within unequipped ones and overlapped less with the trophic niches of the fish captured outside. Fish faeces were also part of the organic matter sedimenting within meadows. In chapter 4, I reported initiatives developed with other scientists. They include species functional diversity and trophic relations within AFH, acoustic signatures of organisms dwelling in AFH and biodiversity comparison between ports and marine reserves using environmental DNA.My work has highlighted several aspects that could improve the effectiveness of AFH as ecological engineering solutions. Immersion time, local environmental conditions, and specific locations within ports need particular attention. Although I did not find clear differences in cross-habitat exchange related to AFH, they seemed to play a role in reducing nutrient enrichment. Moreover, since fish play an important role in cross-habitat exchanges and find refuge within AFH, this ecological engineering solution could indirectly contribute to change trophic connectivity

Full textCette thèse avait pour objet les habitats de l’Infralittoral rocheux Méditerranéen qui ont un rôle de nourricerie pour les juvéniles de poissons (Téléostéens). Cette étude visait à mieux comprendre leurs caractéristiques et les conséquences de leurs transformations, notamment d’origine anthropique, dans le but de rassembler des données utiles à la gestion des zones côtières. Au sein de la mosaïque paysagère sous-marine, parmi les faciès de la biocénose des macrophytes photophiles de la roche infralittorale, les forêts de Cystoseires forment un habitat à macrophytes arborescentes qui est menacé. Cette thèse a démontré que ces forêts abritaient des densités plus élevées de juvéniles de poissons (notamment Labridae et Serranidae) que celles observées au sein de faciès alternatifs, en particulier les brousses à Dictyotales et Sphacelariales et les faciès de surpâturage. La haute valeur relative de nourricerie, que ce soit des forêts de Cystoseires (pour trois espèces du genre Symphodus), ou des petits fonds à blocs et galets (pour les espèces du genre Diplodus), a été observée de manière récurrente dans les différents sites littoraux étudiés aussi bien à l’échelle locale (1 km) que régionale (20 à 100 km). Cependant, pour un habitat donné, les densités de juvéniles ont montré une forte variabilité spatiale entre sites. La variabilité spatiale des densités de juvéniles, aussi bien entres sites des forêts à Cystoseires que d’un habitat à l’autre, était notamment associée aux différences de structure tridimensionnelle de l’habitat (hétérogénéité et complexité). Cette structuration fournissait un refuge pour les juvéniles et a en particulier influencé l’efficacité de leurs prédateurs. Ces travaux, sur la base de manipulations expérimentales et d’observations in situ, ont démontré que les transformations des habitats, telles que la fragmentation des forêts ou la diminution de la densité de leur couverture, réduisaient drastiquement leurs valeurs de nourricerie pour les poissons côtiers. Ces résultats suggèrent que la productivité en poissons virtuellement perdue, dans les zones où les forêts ont déjà totalement disparu, est considérable. Par ailleurs, ces habitats essentiels se sont avérés rares et in-équitablement distribués le long des côtes : dans le cas des Diplodus spp. , moins de 10% des côtes rocheuses étudiées présentaient des habitats nourriceries. Enfin, ce travail a mis en évidence que la planification actuelle des mesures de gestion des zones côtières méditerranéennes ne prenait généralement pas en compte la distribution spatiale des habitats nourriceries, ni leur connectivité avec les autres habitats essentiels à chaque étape clef du cycle de vie des poissons. Un schéma conceptuel, visant à adopter une telle « approche paysage » de la gestion, est proposé : il vise à promouvoir une focalisation optimale des efforts de conservation et à garantir ainsi le renouvellement des peuplements de poissons côtiers

Full textThis thesis focuses on two main problems posed in contemporary fisheries: habitat degradation and lack of information. They count among the most important causes of the overexploitation of marine resources. The first two chapters aim at examining the habitat degradation that is linked to destructive fishing activities. The Gordon-Schaefer model is extended to take account of the negative impact of fishing on the habitats. The consequences for fisheries management are analyzed and the importance of taking into account habitats in the development of fisheries management programs is highlighted. Then the extended model is used to evaluate the economic benefits of artificial reefs, a management tool to which frequently resort the managers of small-scale fisheries to mitigate the effects of habitat degradation. Finally, in the third chapter the role of information for sustainable fisheries is examined under open access. If in the first two chapters it is assumed that there is complete information, in the last study this assumption is relaxed - no information on the resource is known. The decision concerning the exploitation of marine resources is made individually by each fisherman that operates in the fishery. By developing an agent-based model, we show the impact of individual learning on the global dynamics of the system

Full textThis thesis under CIFRE contract aims to offer a methodology to change shore underwater marine systems into artificial habitat for ecosystem and fisheries exploitation. The objective is to give additional tools and answers to professionals specialised in fisheries and ecosystems management. The methodology is geo-systemic, it aims to integrate these changes into the ecosystem and socio-economic systems of artisanal fisheries (strategy type ICAM). The studies conducted on site in Japan taught us how to handle the integration of the underwater world through the relationship between species and their living space. This approach leads us to change the concept of "artificial reef" to the concept of "artificial habitat" as living spaces adapted for species living in a shore environment. The comparison of techniques from Japan, Portugal and France (the priority for these countries is to improve their marine parks with artificial habitat in order to help fishery related professions) helped us to identify a lack methodology in France. It is this global methodology that we want to define. The essence of this methodology is based on the relationship between society and nature at two levels : biophysical and socio-economical. It's organised by typology of artificial living space. Its application on one case study allows us to understand its limits and the necessity to define a common way of using such spaces. AH are participative transactional tools during concerted phases. We demonstrate that the wish to improve underwater living spaces enables the limitation and familiarization of shore territories which was until now unknown. The preservation of the shore ecosystems made possible by this methodology could assist in a balanced development of territorial collectivities

Full textSpawning and juvenile habitats are Critical Essential Fish Habitats (CEFH) that support key phases of the life cycle, when fish aggregate on restricted areas. These CEFH face numerous anthropogenic pressures that impact fish locally. Yet, these impacts are poorly quantified at population scale. This PhD aims to fill this knowledge gap using ageand stage-structured modelling approaches, with explicit representation of the critical life stages on CEFH. A first approach aims to assess the impact of Seine estuary restoration for the common sole in the Eastern English Channel. It uses a hierarchical Bayesian modelling framework integrating a great amount of data and expertise to perform simulations of juvenile habitat restoration. The second one develops a generic mechanistic model to represent marine fish population with contrastedfish population with contrasted life histories. It integrates a comprehensive steepness-based parameterization of the stock-recruitment relationship that directly depends upon juvenile habitat quality and surface area. This model is used to explore population response to juvenile habitat degradation/restoration and its sensitivity to interspecific variability in demographic rates. Then the approach is applied to assess the potential impact of restoring estuarine nursery grounds for four species of main fisheries interest in the Eastern English Channel. Finally, the model is extended to integrate anthropogenic pressures affecting spawning grounds. The main hypothesis and limits of the approaches are discussed; this outlined the large venues of the generic model, for both further scientific investigation and help for management

Full textThe aquatic biodiversity of the Amazon basin, the largest and most species rich river basin on Earth, is still relatively poorly documented despite all the attention received from the international scientific community. Knowledge about the spatial distribution of species, and in particular of freshwater fishes, is very fragmented and dispersed between countries and institutions. The distribution of river forms has been also poorly explored at the scale of the entire basin, its continental dimension limiting the acquisition of field data. Improving the knowledge on the distribution of biodiversity and aquatic habitats in the basin is however a crucial step to better understand the factors and processes behind species diversification, identify priority areas for conservation (biodiversity hotspots) and assess the species vulnerability to global changes. This thesis work aims to reduce these significant knowledge gaps
