Determinism of Temporal Variability in Size at Maturation of Sardine Sardina pilchardus in the Bay of Biscay
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Véron, Matthieu; Duhamel, Erwan; Bertignac, Michel; Pawlowski, Lionel; Huret, Martin; Baulier, Loic.
Age and size at maturation appear as key parameters governing the dynamics of a population as they affect growth rate, fecundity, and survival. The expression of such life history traits is determined by genetic make-up and modulated by environmental factors mainly through phenotypic plasticity. Moreover, fishing, besides decreasing population size and changing demographic composition can alter allelic frequencies through fisheries-induced evolution by selecting for some particular traits. In the Bay of Biscay, a decreasing trend in both sardine body condition and size-at-age has recently been pointed out at the population level. The Probabilistic Maturation Reaction Norm (PMRN) approach was applied to help disentangle phenotypic plasticity and genetic...

Autores: Baulier, Loic; Blanchard, Fabian.
L’existence d’un impact de la prospection sismique pétrolière sur les rendements journaliers des pêcheurs Vénézuéliens ciblant le vivaneau rouge (Lutjanus purpureus) au large de la Guyane au cours de la période 2002–2012 a été évaluée au cours de cette étude. Les informations recueillies dans les fiches de pêche ont permis de tenir compte de facteurs tels que l’effort de pêche, le secteur et la période de pêche ainsi que la profondeur prospectée. Une fois ces différentes influences prises en considération, l’effet de la co-occurrence d’une campagne de prospection a été testé. Les analyses ont révélé des effets des campagnes de prospection positifs ou négatifs mais non significatifs statistiquement à deux exceptions près avec. Les deux seuls résultats...

Using acoustic telemetry to estimate post-release survival of undulate ray Raja undulata (Rajidae) in northeast Altantic
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Morfin, Marie; Simon, Julien; Morandeau, Fabien; Baulier, Loic; Méhault, Sonia; Kopp, Dorothee.
The landing obligation introduced in the reform of the European Union Common Fisheries Policy requires landing all catches of species under quota. However, exemptions may be granted for species for which “scientific evidence demonstrates high survival rates”. Captivity experiments are often used to determine fish survival rates, but they are difficult to perform for large species such as rays due to the limited storage capacity of tanks. Thus, little information is available on ray survival after release despite an identified potential for high survival. We used acoustic telemetry to study rays discarded from a coastal bottom trawl fishery in their natural environment and present a new ad hoc approach to derive a minimum survival rate. After capture under...

Adult-mediated connectivity affects inferences on population dynamics and stock assessment of nursery-dependent fish populations
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Archarnbault, Benoit; Le Pape, Olivier; Baulier, Loic; Vermard, Youen; Veron, Matthieu; Rivot, Etienne.
We explore how alternative hypotheses on the degree of mixing among local subpopulations affect statistical inferences on the dynamics and stock assessment of a harvested flatfish population, namely, the common sole population in the Eastern Channel (ICES area VIId). The current paradigm considers a single, well-mixed, spatially homogeneous population with juveniles from all coastal nursery grounds along the French and UK coasts that contribute to a single adult population and one pool of eggs. Based on the available data and ecological knowledge, we developed a spatial Bayesian integrated life-cycle model that consists of three subpopulations (one near the UK coast and two near the French coast, denoted UK, West FR and East FR, respectively) supported by...

Managing fisheries resources to maintain healthy ecosystems is one of the main goals of the ecosystem approach to fisheries (EAF). While a number of international treaties call for the implementation of EAF, there are still gaps in the underlying methodology. One aspect that has received substantial scientific attention recently is fisheries-induced evolution (FIE). Increasing evidence indicates that intensive fishing has the potential to exert strong directional selection on life-history traits, behaviour, physiology, and morphology of exploited fish. Of particular concern is that reversing evolutionary responses to fishing can be much more difficult than reversing demographic or phenotypically plastic responses. Furthermore, like climate change, multiple...

Can fisheries-induced evolution shift reference points for fisheries management?
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)

Biological reference points are important tools for fisheries management. Reference points are not static, butmay change when a population's environment or the population itself changes. Fisheries-induced evolution is one mechanism that can alter population characteristics, leading to "shifting" reference points by modifying the underlying biological processes or by changing the perception of a fishery system. The former causes changes in "true" reference points, whereas the latter is caused by changes in the yardsticks used to quantify a system's status. Unaccounted shifts of either kind imply that reference points gradually lose their intended meaning. This can lead to increased precaution, which is safe, but potentially costly. Shifts can also occur in...

Reproductive investment in Atlantic cod populations off Newfoundland: Contrasting trends between males and females
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Baulier, Loic; Morgan, M. Joanne; Lilly, George R.; Dieckmann, Ulf; Heino, Mikko.
Life history theory predicts selection for higher reproductive investment in response to increased mortality among mature individuals. We tested this prediction over the period from 1978 to 2013 for three populations of Atlantic cod (Gadus morhua) off Newfoundland. These populations were heavily fished for a long period. We considered changes in standardized gonad weight as a proxy for changes in gonadal investment. We accounted for the allometry between gonad and body weight, individual body condition, water temperature, and potential spatial and density-dependent effects. Males display significant temporal trends in gonadal investment in all populations; in agreement with theoretical predictions, these trends show increased gonadal investments during the...

Habitat suitability for juvenile common sole (Solea solea, L.) in the Bay of Biscay (France): A quantitative description using indicators based on epibenthic fauna
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Le Pape, Olivier; Baulier, Loic; Cloarec, Aurélie; Martin, Jocelyne; Le Loch, Francois; Desaunay, Yves.
This study describes the spatial distribution of young-of-the-year common sole based on beam trawl surveys conducted in late summer in the coastal and estuarine parts of the Bay of Biscay (France). Previous studies showed that habitat suitability for juvenile common sole varies according to physical factors and notably bathymetry and sediment structure. Nevertheless, the use of these descriptors alone to model habitat suitability led to considerable unexplained variability in juvenile common sole distribution. Hence, the epibenthic macro- and megafauna collected during beam trawl surveys was taken into account to improve models of habitat suitability for these juvenile flatfish. Ecotrophic guilds based on life traits (behaviour, mobility and feeding) were...

What is the added value of including fleet dynamics processes in fisheries models?
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Marchal, Paul; De Oliveira, Jose A. A.; Lorance, Pascal; Baulier, Loic; Pawlowski, Lionel.
We develop a spatially and seasonally explicit bioeconomic model with three fleet dynamics processes built in endogenously. The model has been applied to the large French trawlers harvesting a medium-depth demersal stock, North Sea saithe (i.e., pollock, Pollachius virens), and a mix of deepwater species over a 10-year period (1999-2008), and the predictions have been contrasted with observations. The best overall fit was achieved where effort allocation was determined to be 80% by traditions and 20% by economic opportunism and where harvest efficiency increased by 8% a year. With this fleet dynamics parameterization, annual trends in fishing effort and profit were well reproduced by the model over the whole time period. Time series of the observed fishing...

L'évaluation du stock de crevettes café (Farfantepenaeus subtilis) de Guyane a été réalisée à partir des données de débarquement par catégories commerciales des chalutiers guyanais, à l'aide d'un modèle structuré en âge (VPA) paramétré séparément pour les mâles et les femelles. Ce modèle a permis de reconstituer les séries des effectifs et mortalités par pêche mensuels aux âges depuis 1989 jusqu'au mois de juin 2016. L'application d'un modèle de recrutement par recrue a ensuite permis de poser un diagnostic sur le niveau d'exploitation des deux composantes du stock. Ce stock, dont la biomasse a fortement diminué depuis le début de son exploitation, demeure à des niveaux de biomasse bas. L’analyse montre une légère surexploitation de croissance en ce qui...

Autores: Savina-, Marie; Lunghi, Mathias; Archambault, B.; Baulier, Loic; Huret, Martin; Le Pape, Olivier.
Simulating fish larval drift helps assess the sensitivity of recruitment variability to early life history. An individual-based model (IBM) coupled to a hydrodynamic model was used to simulate common sole larval supply from spawning areas to coastal and estuarine nursery grounds at the meta-population scale (4 assessed stocks), from the southern North Sea to the Bay of Biscay (Western Europe) on a 26-yr time series, from 1982 to 2007. The IBM allowed each particle released to be transported by currents, to grow depending on temperature, to migrate vertically depending on development stage, to die along pelagic stages or to settle successfully on a nursery, representing the life history from spawning to metamorphosis. The model outputs were analysed to...
