Etude comparative par electrophorese de Scomber Scombrus et Scomber Colias
Provedor de dados: 5
Autores: Bonnet, Marc; Pichot, Paul.
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...

La "malaïgue" de l'été 1990 dans l’étang de Thau
Provedor de dados: 5
Autores: Pichot, Paul; Juge, Claude; Guillou, Jean-louis.
In summer 1990, Thau, a Mediterranean lagoon was affected by a dystrophic crisis. An aerial survey was performed to observe polluted areas. The analysis of the main environmental water conditions have shown that suspended organic matter plays an important part in the development of this dystrophic crisis.

Etude électrophorétique des protéines du muscle adducteur de l'huître japonaise Crassostrea gigas (Thunberg)
Provedor de dados: 5
Autores: Pichot, Yves; Pichot, Paul.
Cette note rapporte les premiers résultats d'une étude des proteines solubles du muscle adducteur de l'huître Crassostrea gigas (Thunberg) réalisée par électrophorèse. Un polymorphisme existant au niveau d'une fraction de mobilité moyenne est mis en évidence. Il répond à un déterminisme génétique : l'hypothèse d'un contrôle héréditaire invoquant deux allèles codominants est en accord avec la loi de Hardy-Weinberg.

Nouvelle étude sur les fonds de pêche du banc d'Arguin et de ses abords campagne de la «Thalassa», Janvier-février 1971
Provedor de dados: 5
Autores: Bonnet, Marc; Duclerc, Jean; Pichot, Paul.
The great size of the continental shelf, the low landscape of the coasts, the lack of a sailing channel, are factors which make the precise localization of a ship on the bank of Arguin difficult, if not impossible. As a result, the data on the topography, though important, is still incomplete or imprecise. It is almost non-existent for the wide and shallow central shelf located inside the reef area where dangerous sailing adds up to these measuring difficulties. Filling these gaps is needed if we want to continue the exploration of this region and the assessment of the stocks. Concerning the nature of the seabed, a spreading of the sand towards the open-sea is observed, which is the direct consequence of the nearness of the desert, the action of the winds...

Contribution a l'Etude des Serrans, Serranus Cuvier, 1817 (Pisces, Serranidae) de la Reserve Naturelle Marine de Cerbere-Banyuls (Pyrenees-Orientales, France).
Provedor de dados: 5
Autores: Oliver, Guy; Pichot, Yves; Pichot, Paul.
The authors study two populations of Serranus cabrilla, one with a yellow color, the other with a deeper color (orange and brown). They try to see if it is eventually possible to join this duality of coloring to a biochemical difference by the electrophoresis of the eye lens proteins. This technique can give useful indications in a taxonomic study. The results of this work could indicate that the species Serranus cabrilla presents two populations which are separating and tending to a specific individualization. This speciation, perhaps, will tend to the individualization of two species that will be named : Serranus cabrilla for the "red combers" and "Serranus flavus for the "yellow combers".

Résultat de la campagne de pêche au chalut pélagique réalisée à Sète durant l'année 1977
Provedor de dados: 5
Autores: Pichot, Paul; Dremiere, Pierre-yves.
Depuis 1970, année record de la production sardinière en Méditerranée (plus de 22 000 t dont 21 000 t en provenance des quartiers de Port-Vendres, Sète, Martigues et Marseille), la pêche de la sardine s'est trouvée confrontée à de nombreuses difficultés. Avec une production proche de 11 000 t seulement, la campagne sardinière 1976 s'est inscrite dans la ligne d'un certain déclin de la pêche de ce petit pélagique qui, se manifestant depuis six ans, a ramené le niveau de production à celui des années 1960-1965, période de début du développement et d'organisation de cette activité.

Identification des especes du genre Spicara par electrophorese des proteines du cristallin.
Provedor de dados: 5
Autores: Pollard, David A.; Pichot, Paul.
Confusion has arisen over the nomenclature of certain fish of the family Centracanthidia, because of the colour variations due to sexual dichromatism, sexual inversions, protogynous hermaphroditism, and seasonal modifications according to the stage of maturity. A historical survey of nomenclature is presented for species described under the genera Maena, Smaris and Spicara, the last being the most recent. A morphological study and an electrophoretic study of the crystalline lens of the various species involved is described. The techniques and standards used are given. As a result of the study, and bearing in mind the effects of the variations mentioned above, it was concluded from electrophoretic comparisons that only 2 species are valid, Spicara maena and...

Etude électrophorétique des protéines solubles du cristallin de la sardine (Clupea pilchardus Walb.) du Golfe du Lion
Provedor de dados: 5
Autores: Pichot, Paul; Pichot, Yves.
The eye lens proteins electrophoresis of pilchard of the Gulf of Lion (Clupea pilchardus Walb.) shows the existence of 2 sub-populations. The hypothesis of an hereditary control by two co-dominant allels is in agreement with the expected Hardy-Weinberg distribution.

Le Polymorphisme Electrophoretique : Un Moyen d'Etude des Populations.
Provedor de dados: 5
Autores: Pichot, Paul; Pichot, Yves.
The study of biochemical polymorphisms has been known for some years as an important development. The use of a technique called electrophoresis is at the origin of the progress realized in this science. The electrophoretic detection of genetical heterogeneity existing at the level of some biochemical characters of animal species presents an important theorical and practical interest.

Etude électrophorétique des protéines du sérum et du cristallin des merlus de la côte Nord-Ouest africaine
Provedor de dados: 5
Autores: Pichot, Paul.
L'électrophorèse des protéïnes du sérum et du cristallin de Merlucius merlucius, Merlucius senegalensis et Merlucius cadenati a été réalisée sur membrane d'acétate de cellulose et en gel de polyacrylamide. Le matériel étudié provient d'une campagne de chalutage effectuée par le navire océanographique "Thalassa" en mars et avril 1968, du cap Juby au cap Vert. Certaines différences dans la répartition des fractions apparaissent, en particulier un polymorphisme des transferrines. Quatre types de transferrines sont décrites : l'un caractéristique de l'espèce M. cadenati ; les trois autres (A, B, C) étant présents aussi bien chez Merlucius merlucius que chez Merlucius senegalensis.

Structure genetique de la sole (Solea vulgaris Quensel, 1806; teleosteens, soleides).
Provedor de dados: 5
Autores: Pasteur, Nicole; Autem, Michel; Pichot, Paul; Goucha, Moufida.
A survery of Solea vulgaris biochemical polymorphisms is presented with details of the techniques employed. The electrophoretic patterns of GPI, SOD, PGM, GPD, MDH, AAT, ES, GLO, XDH, MOD, IDH and major protein components of the skeletal muscle are described as corresponding to the products of 27 genes, 13 of which were found to be highly polymorphic. The bases and limits of the "locus per locus" interpretation of biochemical polymorphisms for which the mode of inheritance is not available yet are discussed.

Matière en suspension et sédimentation dans la lagune de Thau
Provedor de dados: 5
Autores: Pichot, Paul; Deslous-paoli, Jean-marc; Juge, Claude.
Thau is a mediterranean lagoon with a large productive stock of molluscs (oysters, mussels) cultivated on suspended tines and colonised by epibionta (ascidia and others invertebrates, algae, etc ... ). This study was developed as part of the PNOC-OXYTHAU.programme. Its aim was to analyze the effects of oyster farrning on water-mass surrounding structures loaded with suspended molluscs and proximal watermass separating these structures. This study concems particulate suspended matter and deposits of particulate organic matter on the bottom after sedimnentation. Biochemical measurements were carried out for nitrogen, carbon,  proteins, lipids and carbohydrates. ln order to estimate sedimentaton, bottom sediment traps were used
