| Following the trials conducted in 1958/59 by German trawlers, the I.S.T.P.M. tested for the first time, in 1960, on the Roselys, a 120 CV oceanographic research vessel, a pelagic trawl using a boat equipped with a headrope sounder. The trawl was a double panel trawl with an opening perimeter of 500 80 mm meshes. The lateral opening was made through hydrodynamic Süberkrüb doors of 1,7 sq. meters and 130 kg. Finally, an Atlas Werke netzsonde whose oscillator was set on a platform towed behind a headrope, was transmitting information about the opening and sinkage depth of the trawl to the bridge. The cable only had one conductor and the answer was transmitted through the water. Since then, new cables with two coaxial conductors have been used and results are... |

| The plate tectonic hypothesis admits that the orogenic areas, where most of the mechanical energy vanishes, are the areas where the differential horizontal motions between rigid lithospheric plates occur. The success of this hypothesis relies on the fact that the aseismic deformations inside the plates are less important than the motions occurring along the seismic areas. The rigidity of the plates enables a rigorous analysis of their kinematic. This quantitative model of the evolution of the Earth is an incredible revolution in earth science. It leads to a series of new scientific processes and research involving every different field belonging to earth science. |

| L'introduction d'une nouvelle espèce en ostréiculture donne souvent lieu à des débats passionnés dans les milieux ostréicoles. Un exemple est donné par Charles Martin, parqueur du Bassin d'Arcachon, dans son ouvrage "Agriculteur de la mer"; il rapporte les mesures restrictives qu'avait entraînées l'introduction de l'huître portugaise à Arcachon au début du 20ème siècle. Un des arguments avancés pour expliquer les réticences était celui de la "concurrence vitale" et de la compétition sur le plan nutritionnel (filtration) entre C. angulata et Ostrea edulis: cette dernière espèce était alors seule exploitée dans le bassin. Il fallut attendre l'épizootie de 1920, qui anéantit presque totalement l'huître plate, pour que la portugaise soit définitivement admise. |

| A few observations were mentioned in an earlier paper (COMPS, 1969) that concerned the histological features of the lesions that appeared during the gill infection to which Crassostrea angulata has been particularly prone since 1966. Since it has, however, not been possible to date to isolate and grow a culture of the parasite presumed to be the responsible agent of the disease, a more complete anatomopathological and histological study was contemplated in order to try to specify the definition of the offending protist and reveal the process of deterioration of the oyster's tissues as well as the reactions of the host to the infestation by and growth of the parasite. In addition, importing Crassostrea gigas THUNBERG from Japan at the very moment that gill... |

| Previous research on the mackerel's blood tissue dealt with, on the one hand, blood groups, and on the other hand, the immunology of serum proteins (BONNET, 1967). Their goal was to bring to light the possible existence of distinct races within the species Scomber scombrus. The study by electrophoresis of serum and crystalline lens proteins was undertaken with this same goal in mind. Its aim was, first of all, to determine biochemical characteristics that have a definite taxonomic value, which led us to compare the protein diagrams of Scomber scombrus and Scomber colias. The results obtained are the subject of this report, in which there are also data on the equipment and techniques used. Later research will consist in seeing whether some of these... |

| The artificial production of oyster spats in Japan and the USA provided inspiration to some French oyster farmers who thought that, at a time when stocking up Crassostrea gigas spats was getting more difficult, it would be interesting to try out the nutrition techniques developed by Japanese and American specialists. In this way, in La Tremblade, in the Marennes basin, M. Paul Jarno set up some structures aimed at artificial oyster reproduction. Trials started in 1968 and continued in July 1969. The first step was to assess the material and structures' usability and to take a closer look at the practical larval nutrition conditions in order to obtain fixed spats. This document is a collection of the observations carried out during the different trials. |

| La presqu'île qui s’étend entre les embouchures de la Loire et de la Vilaine, tire une bonne partie de ses ressources de la mer. Aux activités anciennes de pêche et de préparation du sel, sont venus s'ajouter au siècle dernier, la conchyliculture, l'industrie de la conserve de poisson, puis le tourisme balnéaire. Le tourisme trouve là un cadre de choix avec une côte variée où se succèdent des plages renommées comme La Baule, Pornichet, Batz et Le Croisic, des falaises rocheuses, des plages plus modestes ou équipées, et des ports de plaisance. La part du tourisme augmente dans l'économie de la région. Néanmoins, les activités traditionnelles de pêche gardent un intérêt certain à la fois pour diversifier les sources de revenus de la région, fournir à la... |

| This work is about 14 seasonal campaigns carried out by the oceanographic ships Thalassa, La Pélagia and Roselys in the Gulf of Gascony and the Celtic Sea. It aims to highlight the seasonal quantitative variations of planktonic harvests according to the temperature of the waters. In 1964, four campaigns took place: February (98 stations), May (104 stations), August (101 stations) and November (104 stations), which cover an extensive site, from the headlands of Cornouaille to Cape Finisterre. In 1965, the number of stations was fewer: approximately 22 for each campaign. In 1966 (March: 94 stations, May: 99 stations) and 1967 (March: 125 stations, May: 135 stations, August: 140 stations, November: 134 stations) the sector studied does not include the Celtic... |

| Net selectivity in fishing the Norway lobster, Nophrops noruegicus (L., 1758), has only until now been the subject of a limited number of publications. Among the authors who have approached the problem, POPE and THOMAS (1965), COLE and SIMPSON (1965), FIGUEIREDO and THOMAS (1967) emphasized the great variability of the results. The research work that we present here does not claim to be exhaustive. It is appropriate, in fact, to emphasize that our data come from a selectivity campaign mainly devoted to hake (DARDIGNAC, HÉDÉ-HAUY and PORTIER, 1968). The trawls that were used on board the Thalassa are very different, as much by their design and their dimensions as by their meshing, from those used on board the small fishing ships that hunt Dublin bay prawn... |

| The oyster's ability to survive in the absence of oxygen is well known. The only means of defence that these sedentary organisms have for fighting against unfavourable environmental conditions or predators is occlusion of the valves. This implies anaerobiosis potential. This way of life occurs frequently: in the oyster beds, following the most violent storms, the oysters are piled up or covered with sand; they survive in this situation for several days until the oyster farmers put them back to take advantage of the spring tides that enable the drying out of the breeding areas; during periods when the runoff basins are overloaded, the dissolved oxygen content of the sea water are very low and significant mortality rates are sometimes observed in the... |

| Over the course of the last 20 years, new techniques such as electrophoresis have made it possible to approach the detailed study of proteins; they have found many applications in research on taxonomy. The specificity of serum protein electrophoregrammes, in particular, has been noted by a large number of authors. Nonetheless, the value of serum electrophoresis for taxonomic studies is frequently criticised; indeed, physiological state and environmental conditions can alter the proteinogrammes, by variations in the quantitative distribution of the proteins that are normally present as well as by the formation of new proteins. Under these conditions, we thought it worthwhile to use protein electrophoresis on another tissue. The research work of RABAEY... |

| During fishing campaigns for tuna on board the ship La Pélagia in 1968 and 1969 in the Atlantic, between the Gulf of Gascony, the southwest of Ireland and the Azores, the stomachs of caught tunny and those of tunny unsuitable for marking were sampled in order to study their contents at a later time. This study aimed to clarify certain problems relating to tunny feeding and we were able to highlight an endogenous diurnal rhythm in the white tuna's feeding, which is a new contribution to our knowledge about the biology of this fish. Currently, in fact, the problem of tuna feeding is still poorly understood; whereas the bibliography in this area is relatively rich, it is most often limited to lists of wildlife reports. In 1932 and 1940, R. LEGENDRE did an... |

| It is demonstrated that the northern Pyrenean fault can be interpreted as a transforming fault related to the opening of the Bay of Biscay. This fault follows a circle centred to the north of Paris, and along which the Iberian Peninsula could have slipped. As a consequence, the Bay of Biscay could have opened without creating any compression in the Pyrenean area. |

| Il y a plus de cinquante ans, certains océanographes constataient avec étonnement qu'il n'existait pas de carte indiquant la répartition de la flore marine sur les côtes de France. Malgré les excellents travaux de JOUBIN dans la région de Roscoff, ceux de DAVY DE VIRVILLE (presqu'île de Quiberon), les patientes recherches de FLOC'H autour de l'archipel de Molène et celles de DIZERBO (île d'Ouessant), les nombreuses plongées en scaphandre autonome de DRACH et les études de PERES, PICARD, MOLINIER en Méditerranée, les choses n'ont guère changé. Nos connaissances sur la localisation et l'étendue des champs d'algues restent, en effet, extrêmement limitées, surtout en ce qui concerne les peuplements qui n'émergent jamais. Ce fait est d'autant plus regrettable... |

| Ces dernières années, on a vu se développer, tant à la pêche artisanale qu'à la pêche industrielle, la pratique du chalutage pélagique à un ou deux bateaux. En France, cette technique reste le plus souvent complémentaire du chalutage de fond, que celui-ci soit pratiqué avec un chalut de fond traditionnel ou avec un chalut de fond à grande ouverture verticale ou semi-pélagique, mais quelques bateaux y consacrent déjà une bonne part de leurs activités. Les premiers essais de chalutage pélagique ont été faits avec le chalut-boeuf ou chalut pélagique à deux bateaux. En effet, ce type de chalut a été utilisé d'une manière commerciale en France dans les ports du Nord, Gravelines et Dunkerque en 1952 et à Boulogne en 1953 pour la pêche artisanale du hareng. Le... |

| In 1921 the "Pourquoi pas?" undertook, under the authority of J. Charcot, an identification of the Rockall bank (2). The petrographic nature of this relief was studied by Lacroix (2) who concluded to aegirine granite dated, since then, by Miller (3) and Sabine (4), from the early Tertiary period. At the beginning of the Noratlante cruise, in August 1969, the "J. Charcot" carried out a number of profiles, tallying the Porcupine and the Rockall area (fig.1). In addition to the gravimetry and magnetism recordings, an oblique-reflection profile and six Flexotir seismic-reflection profiles (with a frequency comprised of between 10 and 30 cycles) were carried out. We only present here the first results based on this last technique. |
