A Methodological Framework to Estimate the Site Fidelity of Tagged Animals Using Passive Acoustic Telemetry ArchiMer
Capello, Manuela; Robert, Marianne; Soria, Marc; Potin, Gael; Itano, David; Holland, Kim; Deneubourg, Jean-louis; Dagorn, Laurent.
The rapid expansion of the use of passive acoustic telemetry technologies has facilitated unprecedented opportunities for studying the behavior of marine organisms in their natural environment. This technological advance would greatly benefit from the parallel development of dedicated methodologies accounting for the variety of timescales involved in the remote detection of tagged animals related to instrumental, environmental and behavioral events. In this paper we propose a methodological framework for estimating the site fidelity (“residence times”) of acoustic tagged animals at different timescales, based on the survival analysis of continuous residence times recorded at multiple receivers. Our approach is validated through modeling and applied on two...

Analysis of vessel influence on spatial behaviour of fish schools using a multi-beam sonar and consequences for biomass estimates by echo-sounder IRD
Soria, Marc; Fréon, Pierre; Gerlotto, François.
Biases in the measurements of spatial distribution of fish schools and their consequences for school biomass estimates during conventional acoustic surveys are mainly due to vertical and lateral avoidance of the vessel. In this paper, we quantify school avoidance during an acoustic survey carried out from 10 to 29 May 1994 in the Catalan Sea. From a lateral multi-beam sonar the geometric characteristics (depth, length, width, height, surface, and volume) of 1268 schools were obtained. The 60 beams (1.5° X 15°) of the sonar scanned a vertical plane from 0° to 90°, perpendicular to the vessel path within a range of 100 m. Within this plane, the projected area ensonified by the echo-sounder used aboard for acoustic evaluation was evaluated to simulate a...

Changes in school structure according to external stimuli : description and influence on acoustic assessment IRD
Fréon, Pierre; Gerlotto, François; Soria, Marc.
The study of the internal school structure and behaviour of pelagic fish provides interesting information in relation to acoustic surveys, especially when comparing the undisturbed structure with the structure observed beneath a vessel passing over a school. The methodological approach involves in situ observations and combines acoustic and visual (aerial and underwater) techniques. The internal school structure is heterogeneous, including vacuoles, and this structure changes when the school is overpassed by a vessel during the day. In this case compression of the upper layer of the school is observed. The influence of this school structure on the variability of the density estimation has been studied. For the subsurface schools, the usual rate of sampling...

Changes in the fish school structure according to external stimuli IRD
Fréon, Pierre; Soria, Marc; Gerlotto, François.
L'influence de stimuli visuels et auditifs, provenant d'un bateau de prospection ou de prédateurs, a été observée de jour sur des bancs de Clupéidés tropicaux. Ces observations #in situ$ ont été effectuées dans certains cas simultanément depuis un hydravion (ULM) et en plongée sous-marine. Dans d'autres cas on a effectué à partir d'un voilier motorisé des observations acoustiques d'un même banc lorsque le bateau se déplaçait sous-voile, puis au moteur. Il en ressort que la structure interne d'un même banc, sa forme extérieure et le volume qu'il occupe peuvent changer très rapidement dans des conditions naturelles ou en raison des perturbations provenant d'un bateau se déplaçait sous-voile, puis au moteur. Il en ressort que la structure interne d'un même...

Diel variability of school structure with special reference to transition periods IRD
Fréon, Pierre; Gerlotto, François; Soria, Marc.
Pelagic fishes generally dispers at dusk and aggregate in schools at dawn. The dynamics (duration, variation in school number, and characteristics) of these two behavioural processes have been studied during a 26 h survey in a small area of high fish abundance in the Catalan Sea (Spain). The dynamics of aggregation and dispersion were investigated using a dual-beam vertical echo-sounder (BioSonics) connected to a special school integrator software package (INES-MOVIES-B) which estimates school parameters in terms of size, geometry, and density. This study shows that, during the night, fish dispersion is limited and schools can still be observed. They are characterized by a highly skewed distribution of the cross-sectional area (many small schools plus a...

Evaluation of the influence of vessel noise on fish distribution as observed using alternately motor and sails aboard a survey vessel IRD
Fréon, Pierre; Gerlotto, François; Soria, Marc.
L'influence du bruit du moteur d'un bateau de prospection sur les poissons a été étudiée en utilisant alternativement la navigation sous voile et au moteur à bord d'un voilier de 16 mètres équipé d'un moteur diesel inboard de 116 cv. Trois expériences ont été réalisées de nuit sur deux types de population de poissons tropicaux : l'une au large sur des poissons dispersés (probablement des poissons volants et des Myctophydés de la DSL), l'autre sur une couche de poissons pélagiques côtiers (probablement de jeunes Clupéidés et quelques mulets). Dans les trois cas on a observé aucune différence significative de l'influence du bruit du moteur sur la densité, et seulement une faible réaction d'évitement vertical (plongée inférieure à un mètre) s'est produite....

Effective ocean management and the conservation of highly migratory species depend on resolving the overlap between animal movements and distributions, and fishing effort. However, this information is lacking at a global scale. Here we show, using a big-data approach that combines satellite-tracked movements of pelagic sharks and global fishing fleets, that 24% of the mean monthly space used by sharks falls under the footprint of pelagic longline fisheries. Space-use hotspots of commercially valuable sharks and of internationally protected species had the highest overlap with longlines (up to 76% and 64%, respectively), and were also associated with significant increases in fishing effort. We conclude that pelagic sharks have limited spatial refuge from...

Isolation and characterization of eight microsatellite loci from Galeocerdo cuvier (tiger shark) and cross-amplification in Carcharhinus leucas, Carcharhinus brevipinna, Carcharhinus plumbeus and Sphyrna lewini ArchiMer
Pirog, Agathe; Jaquemet, Sebastien; Blaison, Antonin; Soria, Marc; Magalon, Helene.
The tiger shark Galeocerdo cuvier (Carcharhinidae) is a large elasmobranch suspected to have, as other apex predators, a keystone function in marine ecosystems and is currently considered Near Threatened (Red list IUCN). Knowledge on its ecology, which is crucial to design proper conservation and management plans, is very scarce. Here we describe the isolation of eight polymorphic microsatellite loci using 454 GS-FLX Titanium pyrosequencing of enriched DNA libraries. Their characteristics were tested on a population of tiger shark (n = 101) from Reunion Island (South-Western Indian Ocean). All loci were polymorphic with a number of alleles ranging from two to eight. No null alleles were detected and no linkage disequilibrium was detected after Bonferroni...

Short-term variability of Sardinella aurita aggregation and consequencies on acoustic survey results IRD
Fréon, Pierre; Soria, Marc; Gerlotto, François.
A single fish assemblage of #Sardinella aurita$ was tracked over 24 hours by a research vessel equipped with acoustic devices in order to study the short-term variability of its distribution pattern in the Gulf of Cariaco (Venezuela). Obviously the studied assemblage did not follow the usually observed aggregation pattern, considered to depend mainly on the light intensity. Nor did the mean depth of the biomass correspond exactly to the usual diurnal cycle pattern. Dense schools were observed during the first night in absence of moonlight; they dove from 15 to 35 m depth in the morning, but came back close to the surface (19 m) early in the afternoon and remained dense during the following night. Futhermore the fish assemblage apparently presented a...

Structure et stabilité des bancs et agrégations de poissons pélagiques côtiers tropicaux : application halieutique IRD
Soria, Marc.
Afin de cerner le rôle du comportement animal dans les problèmes rencontrés lors de l'estimation des stocks de poissons pélagiques en halieutique par les méthodes d'évaluation directes (acoustique) et indirectes, nous avons entrepris l'étude, en milieu naturel, de la structure et de la stabilité des bancs de petits poissons pélagiques côtiers tropicaux (Clupéidés, Engraulidés). Cette étude est basée sur des observations acoustiques et visuelles (aériennes et sous-marines) simultanées... Nous comparons ces résultats avec ceux obtenus à partir de l'analyse d'une banque de données acoustiques constituée de 18 campagnes effectuées en milieu tropical d'une part, et d'autre part, de l'analyse acoustique de la variabilité d'une concentration de #Sardinella...

Study of learning capabilities of tropical clupeoids using an artificial stimulus IRD
Soria, Marc; Gerlotto, François; Fréon, Pierre.
Learning capabilities of a small tropical pelagic fish, the thread herring (#Opisthonema oglinum$), were studied under experimental conditions. The conditioning consisted of associating a series of three sound pulses with a stress (hoisting a horizontal rigid net from the bottom to the surface). Individual sensibility and school stability measures indicate that fish can be stress-conditioned. Futhermore, these conditioned fish, when mixed with non conditioned fish ("naive" fish), can lead reactions in a school. The results and their influence on fishing are discussed. (Résumé d'auteur)

Variability of Harengula spp. school reactions to boats or predators in shallow water IRD
Fréon, Pierre; Gerlotto, François; Soria, Marc.
The internal structure and behaviour of clupeid schools has been observed #in situ$ during unstressed period followed either by natural predation or by applying a controlled stress (a realistically painted model predator). Combined acoustic and visual (aerial and underwater) observation techniques were used. #In situ$ observations are characterized by a high variability of fish reactions in space and time. The variability in space obviously due to the large scale of observation which allows the silmutaneaous occurence of different types of behaviour in different regions. The variability in time is probably due to a large number of physiological or environmental influences changing unexpectedly between repeated experiments. The variability of fish reaction...
