Full textThough it is acknowledged that human activities modify the environment, the impact of exploitation on populations remains poorly understood. This is the case for the Common Teal population (Anas crecca) in Europe, which seems stable despite high harvests. The analysis of capture-recapture data allows estimating the demographic parameters of this population, which we compare with estimates obtained from a better known North-American population, which is thus interesting for a comparison. We then use a comparative analysis of waterfowl survival to replace our estimates in an inter-specific context and to evaluate the impact of harvest on populations. The proportion of a population that can be sustainably harvested increases accordingly to the reproductive rate of the species. From this point of view, the common teal has a good capacity to tolerate exploitation. However, a demographic model combining available information indicates a strong decline of the population, whereas cencuses indicate that the population is at least stable. Another, spatialized, demographic model shows that a source-sink dynamics is plausible for this population. Some heavily harvested regions deemed to extinction could be maintained thanks to immigration from regions with lower harvests. Based on our results, we discuss some aspects of waterfowl management in Europe

Full textThe consequences of releasing captive-reared game animals into the wild have received little attention, despite their potential impact for receiving populations in terms of demography, behaviour, morphometrics, genetics and pathogens. The present study considers Mallards Anas platyrhynchos released for hunting purposes, an increasing practice in Europe over the last 30 years. Because of domestication process in game farm facilities, our study shows high natural mortality of these ducks once released compared to wild Mallards, in addition to high vulnerability to hunting. A clear genetic differentiation allows discrimination of released and wild Mallards. Hybridization with wild Mallards exists, but did not result into significant introgression. Generally, genetic as well as demographic contributions of captive-bred birds to the natural population were low, but a morphological modification associated with releases was recorded over 30 years in natural population. Ecological consequences of the releases for the wild population seem to be limited, but caution should be maintained on the possible transmission of pathogens (occasionally high prevalence of avian Influenza A in some breeding facilities) and the genetic risks associated with long-term releases

Full textThe Manila clam (Ruditapes philippinarum) was introduced into Arcachon Bay at the beginning of the 1980s for aquaculture purposes. It rapidly naturalized in all intertidal flats of the lagoon. Nowadays, Arcachon Bay ranks at the first French place in terms of exploitable stock. However, recent stock assessments have shown an unbalance size structure with a deficit in juvenile and adult clams (> 38 mm shell length). These alarming patterns asked many questions on the sustainability of Manila clam populations within Arcachon Bay and have motivated the present thesis. This study aimed to better understand the population dynamics of this species and also some factors controlling this dynamic. The final objective was to improve the Manila clam fishing management with a model raised with results of the study. Von Bertalanffy growth parameters (K and L8) were both determined by a field survey of populations and by a tagged-recapture experiment during two years. Growth appeared slow with a homogeneous K within the bay and different L8 according to the sites. This study also evidenced a normal natural mortality and an inefficient reproduction (low condition index, low recruitment). Among the factors that could explain these dynamics, different pathogens were monitored during two years: digenean trematodes, brown ring disease and perkinsosis. Moreover, an emergent pathology (brown muscle disease, BMD) has been discovered. Only perkinsosis and BMD revealed high prevalences and intensities. Perkinsosis induced mitigated effects on growth whereas BMD-infected clams rise to the surface of the sediment and died. Trophic sources were also important to explain growth and were studied with carbon and nitrogen stable isotopes. This study displayed a heterogeneous repartition of Manila clam trophic sources within the bay and a phytoplankton dominated diet. The proportion of ingested phytoplankton was correlated with L8. Growth and mortality parameters were integrated in a management model. If no new management measures were taken, the clam stock will continue to decrease. Different management situations have been simulated and new measures have been adopted by administrator organisms

Full textSenegalese waters presented high fish productivity and stocks are exploited since more than about fifty year. Exploitation intensely increased over the last three decades, inducing ecological changes in the composition of marine populations. Some demersal stocks collapsed to the advantage of other species, characterized by shorter life, such as the octopus and shrimps. Today, these stocks are becoming major stakes of fishing. But short-lived species exhibit rapid and unstable dynamics, and their potential for production varies widely from year-to-year. So, their sustainable exploitation implies an adapted fisheries management, taking into account these specific dynamics. The main objective of the present PhD thesis was to understand the octopus and shrimps stocks’ dynamics, in order to improve the scientific bases of fisheries management plans
