Jacob, Hugo. "Effet des microplastiques sur les jeunes stades de vie des poissons marins." Thesis, Paris Sciences et Lettres (ComUE), 2019. http://www.theses.fr/2019PSLEP075.
Full textEnvironmental plastic pollution is a major ecological and societal concern today. Over the last 10 years, a broad range of laboratory and experimental studies have complemented field observations in the hope of achieving a better understanding of the fate and impact of micro- and/or nano-plastics (MP/NP) on diverse organisms (e.g. birds, fish and mammals). However, plastic pollution remains challenging to monitor in the environment and to control under laboratory conditions, and plastic particles are often naturally or experimentally co-contaminated with diverse chemical pollutants. In fish, the most significant effects reported after exposure to MP / NP were observed on behavioral and neurological functions, intestinal permeability, metabolism and intestinal microbiome diversity. However, plastic pollution remains difficult to quantify in the environment and to control in the laboratory, and plastic particles are often co-contaminated naturally or experimentally with various chemical pollutants. Therefore, studies on the behavioral and physiological effects associated with ingestion of virgin MP / NP in early life stages of marine fish are still few at present. Thus, the purpose of this thesis is to study the effects of two types of plastic frequently encountered in the marine environment, namely polyethylene (PE) and polystyrene (PS), in the form of microplastics (from 10 to 100 μm), on the early life stages of marine fish, known to be particularly sensitive to environmental stresses. Thus, larvae and juveniles of different model fish species (Tropical: Acanthurus triostegus and Temperate: Sparus Aurata) were selected. Several physiological and behavioral parameters were studied after exposure to MP via different pathways (water and food) in various experiments on these model species. Current results do not show any marked effects of this stressor at environmental concentrations, however some results, such as increased mortality and metabolic disturbances, at higher doses, show toxicity following ingestion of these particles. Thus, this thesis reveals that the toxicity of virgin PM / NP on fish should be evaluated more systematically using rigorous laboratory methods, in order to gain a better understanding of the underlying mechanisms of this toxicity to fish

Full textThe European eel Anguilla anguilla is a catadromous fish with a large scale migration loop including the Sargasso sea, Europe and North Africa. In the last 30 years, drastic declines of abundance have been observed and the species is currently considered as critically endangered. One of the main causes of species decline is habitat fragmentation, which prevents migrating fish accessing growth zones.We studied whether aquatic obstacles can enact selectively on migrating young eels. We applied a no a priori approach to detect any traits involved in the process of obstacle passage. We used a microarray analysis for gene expression screening in three tissues (brain, liver, muscle) of young eels sampled in different sections of an impounded watercourse (article 1). The only differences detected between groups of fish concerned the brain tissue, and the detected genes were related to synaptic plasticity. We also found that transcription levels of genes related to neural activity, oestrogen and thyroid metabolisms were different after two months of common garden (article 2). Finally, we studied the relationship between the gene transcription and climbing behaviour (article 3). Upstream fish showed the highest climbing tendency. Moreover, we found that the ‘climbing’ leaders showed lower transcription levels of cognition-related gene than fish following them. We suggest that leaders can enact as bold and proactive individuals, in contrast to reactive followers.The implication of our results is discussed in an ecological context, where the presence of water obstacles can modify the distribution of different phenotypes in the upstream and downstream parts of the water axis

Full textThe common cuttlefish Sepia officinalis, is a major exploited marine resource in the English Channel. It has strong seasonal and interannual variations in recruitment. Mechanisms affecting the renewal of the stock by the arrival of new “recruits” and their number need to be better understood. Thus the study of the spatial and temporal variability of “pre-recruits” physiological characteristics was conducted in four spawning sites of the Channel [i. E. Agon Coutainville (FR), Baie de Seine (FR), Selsey (UK) and Torbay (UK)]. The studied parameters were the eggs quality and hatching rate then, the digestive and immune performance of juveniles in relation to local environmental conditions. English eggs have a delayed hatching time and higher hatching rate when compared to the French ones. Temperature and salinity are important in understanding these differences. The digestive performance of hatchlings varied according to the site. The study of immune enzyme activities showed local vulnerabilities of early stages which corresponded to episodes of high mortality. These mortalities are correlated with low protein content and low immune activities in eggs. These results underline how variability in the spatio-temporal characteristics of the early life stages of cuttlefish can influence the contribution of spawning sites to S. Officinalis stock in the English Channel

Full textIn this study, we considered parental influences on offspring energetic status in brown trout (Salmo trutta) and their consequences on offspring emergence and fitness. We adapted recent micro respirometry techniques and elemental CHNS-O analysis to measure individual energetic status of offspring from fertilisation to emergence. By combining these individual measurements to hierarchical modelling, we estimated parental influences on offspring energetic status throughout ontogeny and at the onset of emergence, and evaluated their consequences on the timing of this first ontogenetic niche shift and offspring growth and survival. Our results show that parents control offspring emergence dynamics and offspring fitness through their effects on offspring energetic status mean expectancy and variance
