Aménagement intégré de la pêcherie crevettière en Guyane. Adaptation et utilisation du système Argos pour la collecte de données de pêche ArchiMer
Dintheer, Christian; Cadiou, Yvon; Leroy, Claude.
Pour améliorer la gestion de la pêcherie crevettière de Guyane française a été développée et expérimentée une application halieutique du système ARGOS. Deux prototypes TMA 85 ont été mis au point en tenant compte des conditions particulières de cette exploitation puis embarquée sur deux chalutiers. Ils se composent d'une balise BA 10 et de son antenne, et d'un microcalculateur sur lequel les capitaines enregistrent des données de pêche grâce à un logiciel spécifique calqué sur les fiches de pêche traditionnelles. Après un an d'utilisation dans des conditions commerciales, ce nouveau moyen de collecte d'informations apparaît performant. Robuste, facile d'emploi, il permet la mise à disposition rapide des armements et des scientifiques de messages complets,...

Analyse économique de la pêcherie crevettière de Guyane Française ArchiMer
Gilly, B.; Cochet, Y..
The french Guyana sh rimp fishery has grown from the sixties, following the development of US a nd Japanese fleets. The EEZ delimitation in 1977 and the french policy towards promotion of french vessels allowed, since 1980, the emergence of french ship-owners. The paper analyses the recent economie evolution of the enterprises and underlines first the importance of this activity within regional economy, and second its dependance on imported inputs. The french policy leads to an incrcase of the share of the net added value that remains in the depanment, but it also come to a poor financial status of the french ship-owners. The data collected and given in this paper will be used to feed a bio-economic model o f the shrimp fishery.

Caractérisation de bactéries lactiques psychrotrophes en vue de leur utilisation dans la biopréservation des aliments. Étude physiologique et moléculaire des mécanismes d’adaptation au froid ArchiMer
Matamoros, Sebastien.
Lactic acid bacteria strains were isolated from seafood products and clustered according to their inhibiting capacities against 14 food borne spoiling and pathogenic strains in order to develop applications in biopreservation. Most of the strains were identified as Leuconostoc gelidum and Lactococcus piscium. Detailed identification of one strain of the Lactococcus piscium strains suggests that it is a new specie. According to sensory analysis results, 2 strains belonging to the Leuconostoc gelidum specie were the most efficient for the enhancement of the shelf life of vacuum packed peeled and cooked shrimps. Similar results were obtained in cold smoked salmon with one strains of Lactococcus sp. A challenge test against three pathogenic strains (Listeria...

Croissance relative, sex-ratio et exploitation de la crevette blanche metapenaeus monoceros (fabricius, 1798) du golfe de gabes (tunisie) OceanDocs
Jarboui, O.; Ben Abdallah, O.; Missaoui, H.; Ben Hadj Hamida, N..
Les crevettes, particulièrement Penaeus kerathurus, sont considérées parmi les espèces de crustacés les plus exploitées au niveau des côtes tunisiennes, essentiellement dans le golfe de Gabès. Depuis l’année 1993, une nouvelle espèce de crevette d’origine lesseptienne est apparue dans le golfe et s’est bien adaptée avec ses conditions climatiques et environnementales : c’est la crevette blanche Metapenaeus monoceros. L’objectif principal de cette étude consiste à suivre l’exploitation de cette espèce dans la région du golfe de Gabès, à étudier sa croissance relative et à déterminer la composition des captures selon le sexe. D’après les résultats obtenus nous avons pu constater que, durant la dernière décennie, la production de cette espèce dans le golfe de...

Crustacés profonds capturés aux casiers aux Antilles Françaises ArchiMer
Paulmier, Gerard.
For several years the fishermen of the West Indies have directed their activities towards new fishing grounds, notably the bathyales zones adjacent to island plateaux up to approximately 1000 metres in depth. Explorations earned out since 1989 have shown that diverse crustacean populations could be exploited. However, populations and exploitable stocks arc not well known. The use of crustaceans traps as a fishing technique permits the capture of shellfish, shrimps and prawns of which at least six species could have commercial interest. The main objective of this work is do draw up an inventory of the principal commercial species as well as the accompanying species belonging to the subordres Decapoda macrura, anomura, brachyura, and to the orders Isopoda...

Etude des tris précoces en élevage de crevettes P. stylirostris dans un objectif de sélection génétique. Février à Juillet 2000. ArchiMer
De Decker, Sophie.
Schemes optimisation for genetic improvement for growth of Penaeus stylirostris requires the development of technologies for grading shrimps easily. This work shows that bar and mesh graders are very suitable for early selection at post-larval stages, as long as early growth is heritable. Experimental data sets lead to the equations which give the grading weight as a function of the dimensions of the graders. Mesh graders which allow an earlier selection than bar graders (PL19 instead of PL25) open a new way to implement experimental selection into production hatcheries.

Etude d'un milieu gélose semi-sélectif pour la recherche de Vibrio penaecida : tests de nouvelles méthodes diagnostiques dans le cadre du programme de recherche sur le syndrome 93 ArchiMer
Lapouyade, Patrick.
Ce travail décrit la mise au point d'un milieu gélosé semi-sélectif visant à mettre en évidence les Vibrio penaecida en élevage larvaire de pénéides. Le ZoBell-Mannitol-Saccharose-Bleu de bromothymol (ZMSB) a un pH élevé, une forte teneur en sels et ne possède que deux sucres acidifiables, le mannitol et le saccharose. Ce milieu peut être utilisé pour la sélection d'un grand nombre d'espèces du genre Vibrio. La salinité et le ph séparent le germe cherché d'une fraction importante d'espèces de Vibrio, et l'acidification du mannitol et du saccharose révèlent (par le changement de couleur du milieu) les Vibrio de type penaecida qui présentent cette caractéristique. De plus, un milieu minimum comme le ZoBell, additionné de glycérol, permet d'augmenter...

Expériences sur l'influence des sédiments du bassin d'élevage sur la physiologie de Penaeus stylirostris. Rapport des travaux menés du 26 novembre au 7 décembre 1955 à la Station Saint Vincent ArchiMer
Cochard, Jean-claude; Goarant, Cyrille; Boglio, Eric; Lemonnier, Hugues.
The influence of the soil quality of culture pond on the physiological state of Penaeus stylirostris reared in earthen shrimp pond in New Caledonia was investigated by the measurement of the osmoregulatory capacity and magnesium hemolymph concentration of samples of 20 of these shrimp captured in the pond and maintained for 24 or 48h in cages laid on the bottom. A first experiment was affected by the occurrence of a pathology caused by Vibrio penaeicida probably due to initial handling stress. The second experiment showed that the osmoregulatory capacity is depresssed as a function of the soil quality : the more it is reduced the more the depression is important.

Marine crustacean farming: present status and perspectives ArchiMer
Laubier, Annie; Laubier, Lucien.
For centuries, several species of prawns and crabs have been raised from wild-caught juveniles in coastal brackish-water fish ponds in various countries of south east Asia. The Indonesian "tambaks" are well known examples of such traditional practices. In western countries, since the turn of the century, advances of marine biology and fast increase of marine fisheries enabled the development of large-scale production and release of larval stages of American and European lobsters in a fruitless attempt to restock natural populations. After the Second World War, the increasing demand for crustaceans in United States and Japan was satisfied by opening new prawn fisheries all over the world. A major breakthrough was achieved with the development of hatchery...

Toxicité aiguë du tétrachloroéthylène sur la crevette des marais Palaemonetes varians ArchiMer
Miossec, Laurence; Bocquene, Gilles; Truquet, Philippe.
Studying the impact of domestic sewer discharge on marine biota we studied lethal toxicity of tetrachloroethylene on brackish water prawn (Palaemonetes varians). These experiments were carried out in a flow-through system during 96 hours : LC 50 is 2,37 mg/l. This result and aIl data, present in litterature, show the high sensitiveness of crustaceans to this chlorinated solvent.
