The European seabass (Dicentrarchus labrax) is a species of particular ecological and economic importance. Stock assessments have recently revealed the worrying state of the “Northern stock”, probably due to overfishing and a series of poor recruitments. The extent to which these poor recruitments are due to environmental variability is difficult to assess, as the processes driving the seabass life cycle are poorly known. Here we investigate how food availability and temperature may affect the growth and survival of wild seabass at the individual scale. To this end, we developed a bioenergetics model based on the Dynamic Energy Budget (DEB) theory. We applied it to seabass population of the Northeast Atlantic region (Bay of Biscay – English Channel area)...

Characterising Essential Fish Habitat using spatio‐temporal analysis of fishery data: A case study of the European seabass spawning areas

Fish habitats sustain essential functions for fish to complete their life cycle, such as feeding, growing and spawning. Conservation is crucial to maintain fish populations and their exploitation. Since 2013, the spawning stock biomass of the northern stock of European seabass (Dicentrarchus labrax) has been in a worrying state. A series of low recruitments with a persistently high level of fishing has been blamed, raising concerns about the processes involved in seabass reproduction and settlement in nurseries. Here, we characterise seabass spawning areas along the French Atlantic coast using vessel monitoring system (VMS) data. A non‐linear geostatistical approach was applied, from 2008 to 2014, to detect locations where seabass aggregate for spawning....

Caractérisation et connectivité des Habitats Ecologiques Essentiels des stades adulte et juvénile du bar européen

Essential Fish Habitats host, at least, one stage of their life cycle. As they can be distant, maintaining their connectivity is essential for the closure of fish life cycle and populations’ sustainability. This thesis focused on the connectivity between spawning areas and nurseries of European seabass. Its main spawning areas have been characterised using a non-linear geostatistical approach applied to highly resolved fishery data. A Bayesian spatio-temporal model showed that they are mainly explained by a stable spatio-temporal structure, rather than by hydro-climatic factors. A bioenergetics model (DEB) over the entire life cycle of seabass was developed and validated for the early life stages. It showed that larvae and juveniles are resistant to low...
