Caracteristiques topographiques et thermiques d'un site de ponte majeur de la tortue verte Chelonia mydas dans l'Ocean Indien sud-ouest: Europa ArchiMer
Le Gall, Jean-yves; Taquet, Marc; Cluet, Denis; Biais, Gerard.
The beach of the meteorological station of Europa Island (Indian Ocean S.W.) is a major nesting site for the green turtle. Altimetric distribution of nests on the beach is such than 95 % of nests are laid in the band located between 1.25 and 3 m above the mean level of upper tides. Nest density is a function of adult females number and varies from 0.175 to 0.043 nest/m2 for the two analyzed nesting seasons. Ground temperatures at 60 cm and 100 cm depth range from 22 (winter) to, 30°C (summer). Interannual variability of ground temperature at same depth (incubation depth) is 1.5° C from extreme hot to cold years. These intra and interannual variations are supposed to have an effect upon the sex-ratio of hatchlings

Ecophysiologie de la maturation sexuelle et de la ponte de l'huître creuse Crassostrea gigas : réponses métaboliques (respiration) et alimentaires (filtration, absorption) en fonction des différents stades de maturation ArchiMer
Soletchnik, Patrick; Razet, Daniel; Geairon, Philippe; Faury, Nicole; Goulletquer, Philippe.
The study of sexual maturation and spawning in the Pacific oyster (Crassostrea gigas) is part of a vast research programme that endeavours to understand the causes of mortality that occur sporadically during the spring and summer seasons in the Marennes-Oléron Bay. Thermal and diet conditioning were used to obtain oysters at each stage of maturity simultaneously. Using the measured rates of clearance, consumption, absorption and respiration provided estimates of growth potential and gave the energetic budget of oysters at different stages of sexual maturity. Physiological responses were similar for males and females. Filtration decreased from 2.4 to 2.6 l.h (-1) to 1.8 l.h (-1) with increasing maturity. Weight gain was associated with gonad development and...

Estimation du nombre de tortues vertes femelles adultes Chelonia mydas par saison de ponte à Tromelin et Europa (Océan Indien) (1973-1985) ArchiMer
Le Gall, Jean-yves; Bosc, Pierre; Taquet, Marc.
A research programm on the marine green turtle Chelonia mydas nesting on the two major reproduction sites for the species in the Indian Ocean, conducled over last 15 years, included intensive tagging programm. Processing of these lagging data provides estimations of adult female populations {or each site and season from two independent methods. First classical method is the ratio of total number of nests produced over a define time on the mean individual number of nests by female during the same time (November, December, January). The computed mean individual number ranges from 3 to 3.5 obtained over 2 to 3 months. The second method is the multiple capture-recapture method (JOLLY, 1965; SEBER, 1965; MANLY, 1984). Il is an original tentative of applying...

HLiN. Huı̂tres du Littoral Normand. Ponte, Dispersion, Recrutement et Colonisation des huı̂tres sauvages sur l’Ouest Cotentin : un réseau de suivi pour le littoral normand. Etude de cas 2013 ArchiMer
Pien, Sebastien; Maheux, Frank; Dedieu, Karine; Le Gendre, Romain; Simon, Benjamin; Gauquelin, Thibaut.
Depuis 2010, le programme HLiN s’attache à suivre la colonisation et le recrutement des huîtres naturelles sur les côtes du département de la Manche. Après une période d’adaptation des protocoles à la réalité normande, il s’est posé la question de l’origine du recrutement des huîtres, notamment pour la côte ouest du Cotentin, entre les falaises de Champeaux et Saint Germain / Ay. Suite à ses travaux sur la dérive larvaire des moules de pêche en baie de Seine, le LERN de Port en Bessin avait mis au point un modèle de courantologie en 3 dimensions appelé NORM (issu du code MARS 3D). L’idée était d’appliquer la méthodologie de calage du modèle pour le golfe normand breton afin de simuler différents scénarios de ponte et de les corréler avec les observations...

Les variations de la fécondité de la coquille Saint-Jacques de la Rade de Brest en écloserie au cours du cycle annuel ArchiMer
Cochard, Jean-claude.
Among the different biological factors which can have an impact on the recruitment of the king scallop, the relationship between the number of produced oocytes and the number of obtained larvae can be tackled from an experimental point of view. In the framework of the repopulation program of the roadsted of Brest (king scallop pluri-annual program), the hatchery spat production trials (Buestel et al., 1982) enabled the monitoring of the variations of the real fertility of Pecten maximus over a year cycle. The natural egg-laying period in the roadsted of Brest spreads from June through to September, but egg-laying can also be triggered artificially all year long. The results obtained during production trials in 1982-1983 and the action of low temperatures...

Mise au point technique de l'élevage de l'ombrine Sciaenops ocellata. Document 2 : Maturation et pontes ArchiMer
Soletchnik, Patrick; Goyard, Emmanuel; Thouard, Emmanuel.
Depuis de nombreuses années, les biologistes étudiant des poissons d'eau douce, ont mis en évidence les relations existant entre le cycle de maturation et les facteurs environnementaux tels que la température et la photopériode (Bullough, 1940 ; Merinan & Schedl, 1941 ; Harrington 1957, Henderson, 1963...). En aquaculture, pour des espèces tempérées comme le loup, la dorade, le turbot, dès 1973, l'opportunité du décalage de la saison de ponte grâce au raccourcissement des cycles environnementaux naturels, est démontré (Girin & Devauchelle, 1978). Sur le loup (Dicentrarchus labrax), des pontes décalées ont pu être obtenues par manipulation du seuil facteur est également reprise par Suquet (1987) puis par Bouget (1988), sur la dorade (Sparus aurata)....

Modélisation de la croissance de Ruditapes philippinarum dans un système expérimental ArchiMer
Bensch, Alexis; Bacher, Cedric; Baud, Jean-pierre; Martin, Jean-louis.
The growth of Ruditapes philippinarum was modeled with an energetic budget equation. Clams were fed with Skeletonema costatum in experimental units during 6 months. The filtration and respiration terms of the budget were depending on the temperature and the dry weight. The spawning effort was represented by an allometric relation derived from the experimental data. The model simulated the individual growth of the dry weight and of the shell converted into energy during the 6 months of the experiment. The results fitted well with the observations until the loss of energy due to the spawning. After that period the model overestimated the growth which was explained by another spawning loss not taken into account in the model and not noticeable with the...

Observations sur la maturité sexuelle et la ponte du tourteau Cancer pagurus en Manche ArchiMer
Latrouite, Daniel; Noel, Philippe.
Few observations have been reported on the reproductive cycle and size at maturity of female edible crab in the Channel. This could be linked to non catchability of berried females. During the present study carried over three different years, females were taken from commercial catches prior to the spawning period and placed in tanks in the laboratory. The various criteria used to establish the mean size at first maturity are discussed and the relation between size and functional maturity is described. The smallest berried females are at a carapace length of 76mm, and maximum values are reached at about 105mm. The mean value is between 85 and 90mm carapace length. The duration of the spawning period was the same in each years, extending from mid-November to...

Répartition des oeufs et larves de sardine dans le Golfe de Gascogne et sur le plateau celtique (mai 1966 ; février et mai 1967) ArchiMer
L'Herrou, Roger.
La ponte de la sardine en 1964 dans le golfe de Gascogne et sur le plateau celtique a été récemment étudiée à l'Institut des Pêches par S. Arbault et N. Boutin dans le cadre d'une travail plus général sur la répartition saisonnière des oeufs et larves de téléostéens, travail que résume une communication présentée au Comité du plancton. Les résultats exposés ici et limités à la seule sardine, font suite à l'étude des ces chercheurs et proviennent du dépouillement des pêches planctoniques de 3 campagnes d'hydrologie des pêches effectuées par la Thalassa et la Pélagia dans la même région du 26 avril au 9 mai 1966, du 13 février au 22 mars 1967 et du 16 mai au 7 juin 1967.

Reproduction de l'huître creuse (Crassostra gigas) dans le Bassin de Marennes Oléron. La pêche expérimentale de larves d'huîtres, indicateurs de ponte et de recrutuement. Analyse spatio-temporelle et relation avec l'environnement ArchiMer
Soletchnik, Patrick.
This study is based on catched larvae data base produced since C. gigas was first imported into the Charentais Sounds (late 1960s, early 1970s). The method for catching larvae using a towed net remained unchanged between 1950 and 1998. Four sites have been sampled in the Bay since 1970, two situated in the Seudre estuary and two in the middle of the Bay. Two other sites from near the mouth of the Charente River have been sampled since 1982. For each sample, oyster larvae were counted in four size classes, from the young larva (1-4 days) to near metamorphosis (16-20 days). Each year, 100 to 150 captures were carried out at all sample sites between June and September. Captures from July and August represent 99% of the total. The main variables were: capture...
