Consommation d'oxygene de la crevette japonaise, Penaeus japonicus , en fonction de l'oxygenation du milieu: Effects de la temperature et de l'acclimatation a des conditions ambiantes hypoxiques
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Truchot, J; Jouve, D.
Oxygen consumption of juvenile prawns, Penaeus japonicus , was measured during the day at 4 temperatures (23, 26, 30 and 33 degree C) and at various oxygenation levels. For inactive prawns burrowed into sand, respiratory metabolism was maintained almost constant in hypoxia above a critical oxygen pressure of about 30-40 Torr. Data analysis according to a hyperbolic model indicates that the capacity for metabolic regulation was optimal between 26 and 30 degree C. Prawns acclimated 1-2 weeks at 20 degree C in moderate hypoxia (P sub(O2) around 50-55 Torr) showed a reinforced regulation of oxygen consumption when compared to normoxic controls.

Microparticulate feeds for Penaeid larvae
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Kanazawa, A.
The mass production of penaeid larvae still depends on live foods such as diatoms, Chlorella and Artemia . However, it requires much facilities, maintenance expenses, and labor to produce a desired amount of life foods safely and constantly. Also, the nutritive value of planktonic organisms is occasionally variable and this makes the use of live food for mass culture restrictive. Therefore, it is necessary to develop microparticulate diets as a substitute for live foods to further increase the productivity of seed for shrimp culture.

Morphogenese sexuelle et regulation hormonale de l'activite genitale chez la crevette Penaeus japonicus en elevage
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Laubier, A; Chim, Liet; Payen, G.
A study of the sexual physiology of penaeid prawns essentially based upon Penaeus japonicus is performed in both descriptive and experimental ways, using the controlled rearings conducted at the Centre Oceanologique de Bretagne (CNEXO-COB), Brest. Sexual morphogenesis is described. This preliminary study enables definition of simple criteria for determination of the stage of genital development of the prawns during their growth. The neuroendocrine control of the genital system development is studied, using eyestalks ablations and male eyestalks extracts injection in prawns belonging to the same sex. A biochemical criterion as a test of the effect of eyestalks extract injections on the genital system development is discussed. The evolution of the specific...

The nutritional requirements of the Japanese shrimp Penaeus japonicus
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Guillaume, Julien.
Penaeus japonicus is probably the best known species among penaeids or even among shrimps. In juveniles, the protein requirement was best studied and Japanese shrimp appears as the most demanding penaeid species. They may be related to several factors such as energy level of the diet, digestibility or biological value of protein or other nutritional factors. The essential amino acids are well known, however from a quantitative point of view the requirements in each of these amino acids remain to be determined.

Etude comparative de la qualité du milieu de bassins aquacoles de crevettes et palourdes chez des éleveurs du marais Breton (Vendée, Loire Atlantique)
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Gautier, Dominique.
Une étude du milieu de cinq bassins d'élevage a été menée du point de vue de la qualité de l'eau (température, salinité, oxygène dissous, pH, chlorophylle A, nutriments) et de la qualité du sédiment (matière organique, carbonate de calcium, épaisseur de vase organique, macrofaune dominante). La salinité, contrairement à la température, est fonction de la fréquence et du mode de renouvellement. Les variations nocturnes du pH de l'eau sont en relation avec celles de l'oxygène dissous qui sont elles-mêmes fonction de la concentration en chlorophylle a. La fluctuation du pH de la colonne d'eau differe selon les bassins. Elle peut être stable (autour de 8,1) ou très variable (entre 7,6 et 8,6), sans être toujours en relation avec la concentration en...

Influence du taux de proteines sur la croissance ponderale de Palaemon serratus (Pennant) elevee au laboratoire
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Campillo, Albert; Luquet, P.
The quantitiative requirements for protein have been determined in P. serratus reared from the post-larval stage to the 4th month. It appears that the apparent optimum percentage of protein in the diet is a minimum of 60%. At the 8th month, the mean wt of prawn reared with the best artificial diet (diet IV) is only 49% of the wt of shrimp reared with the digestive gland of Patella as a diet. The prawns reared to 4th month on a low-protein diet then reared on a natural diet until the 8th month, show important compensatory growth. However, the prawns do not achieve the wt of the control population, their average wt representing only 16% of the controls.

Enrichment of live foods.
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Watanabe, T.
Live foods such rotifers and Artemia are still indispensable for mass propagation of larval fish. At present, more than 20 fish and crustacean species are mass produced in Japanese governmental fish farming centres and private hatcheries. Fry are either released into the coastal areas or used for commercial cultivation. This culture technology is rapidly developing with new species being introduced each year and larval rearing is increasingly identified as the number one constraint. Artemia is used most extensively, particularly for the mass production of Kuruma prawn, Penaeus japonicus .

Detection of a mollicute-like organism in kuruma shrimp, Penaeus japonicus
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Choi, Dong-lim; Park, Myoung-ae; Sohn, Sang-gyu; Heo, Moon-soo; Renault, Tristan.
A filamentous form of mollicute-like bacterium was detected during a routine health survey of wild adult kuruma shrimp Penaeus japonicus. The kuruma shrimp were native to Japan and were imported to Korea. The histology showed no pathological changes. Transmission electron microscopy revealed extensive infections of hepatopancreatic epithelial cells by a pleomorphic, filamentous intracellular bacterium. The filamentous bacterium was of about 60 nm in diameter and 300 nm to more than 1µm in length. The morphology of bacteria were filamentous and branched with terminal blebs, or knobs, on the branches. They lacked the cell wall, and were bounded by the plasma membrane. They contained typical prokaryotic ribosomes and fibrillar DNA-like strands. No additional...

Biologie et pêche traditionnelle des crevettes pénéides dans l'embouchure d'un fleuve en milieur semi-aride (sud-ouest de Madagascar)
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Laroche, Jean; Benoely,; Siaviri, A.
Traditional fishing using beach seines was studied over a period of one year at the mouth of the Onilahy river. The catches/efforts were recorded on a daily basis, biological sampling and the measurement of hydrological parameters being carried out twice a month. The moderate variations of salinity and temperature (14 &lt; salinity &lt; 35; 25 degrees C &lt; temperature &lt; 30 degrees C) which were observed in the estuary can be explained by the semiarid climate of the area. Four species of penaeid shrimps are to be found on the Onilahy: Metapenaeus monoceros, Panaeus indicus, Penaeus monodon and Penaeus japonicus, which were mainly caught at the subadult/adult stage with a Carapace length between 10 and 50 mm. The presence of these important sizes at the...

Mineral requirement of Penaeids
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Piedad-pascual, F.
Marine shrimps absorb minerals from their aquatic environment aside from the minerals that come from the food they eat. Thus, the dietary requirement of shrimps for certain minerals will depend on the amounts and availability of these minerals in the aquatic environment. Dietary sources for growth may be necessary due to losses during moltings.

Protein requirements of Penaeid shrimp.
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Kanazawa, A.
Proteins are indispensable nutrients for growth and maintenance of live of all animals. The optimum protein levels in diets for shrimps are different among the various species. Squid meal is an effective protein source for many penaeids. The effects of dietary protein, lipid, and carbohydrate levels on the growth and survival of larvae of Penaeus japonicus were examined by feeding trials using purified diet with carrageenan as a binder. As a result, the effects of protein levels on growth and survival of P. japonicus larvae varied with dietary carbohydrate levels but not dietary lipid levels.

Evolution de la communaute bacterienne heterotrophe de l'eau de mer lors d'une experience d'aquaculture de crevettes peneides en systemes clos
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Sohier, L; Bianchi, M.
The quantitative and qualitative evolution of the heterotrophic bacterial community of sea water was studied throughout an experimental rearing of Penaeus japonicus in closed systems. Cluster analysis was realised on 417 strains coming from water sampled at different moments of the experiment. This collection includes 40 strains coming from a mussel used for diet and 40 strains coming from the digestive tract of one prawn after six months rearing. Quantitative and qualitative studies have both shown a similar evolution of heterotrophic microflora whatever the initial animal load was. The dendrogram obtained led to a description of characteristics of the various populations constituting the heterotrophic bacterial community of the water environment...

Estimation du polymorphisme enzymatique d'une population de Penaeus jap nicus maintenue en élevage depuis quatre générations
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Laubier, A; Pasteur, N; Moriyasu, M.
The polymorphism of 37 enzyme-encoding genes was investigated in a Penaeus japonicus population born the same night from a stock maintained artificially four generations. Five loci were found to be polymorphie (Lap-4, Es-3, Es-6, Es-8 and Mpi-2), and genotype frequencies at four of these loci indicate: a) that the shrimps studied come from the same two parents and b) that Mpi-2 and Es-3 genes are autosomal. The rate of polymorphism observed in this Penaeus japonicus population is similar to that described in natural populations of other Peneidae species, despite the probable occurrence of inbreeding.

The role of astaxanthin in shrimp pigmentation
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Latscha, T.
Carotenoids are exogenously derived isoprenoid compounds which are responsible for pigmentation in crustaceans. While implants and bacteria are able to synthesize these carotenoids de novo, shrimps like other animals entirely depend on their dietary supply. The major carotenoid found in most crustacean tissues and responsible, e.g. for the typical colour of penaeids is astaxanthin. With increasing industrialization in shrimp farming there is a growing demand for synthetic, nature-identical carotenoids, not only for pigmentation, but also for the maintenance of growth and fertility.

A review of the known hosts geographical range and current diagnostic procedures for the virus diseases of cultured penaeid shrimp
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Lightner, D; Bell, T; Redman, R.
At least six virus diseases are presently known in cultured penaeid shrimp. Each of these six penaeid virus diseases (BP = Baculovirus penaei ; MBV = Penaeus monodon -type baculovirus (including PBV of Australian penaeids); BMN = baculoviral midgut gland necrosis; HPV = hepatopancreatic parvo-like virus; IHHNV = infectious hypodermal and hematopoietic necrosis virus; and REO = reo-like virus of the hepatopancreas) may be comprised by a multitude of individual strains, some of which are highly pathogenic to some penaeids, while being of little importance to others.

Grossissement de crevettes Penaeus japonicus dans les marais de l'Atlantique. Résultats des essais d'intensification 1986 à 1988
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Aqualive.
From 1986 to 1988 assays have been achieved in Noirmoutier IFREMER station aiming at increasing yield of grow-out of P. japonicus under semi-intensive conditions in earth ponds. Rearing methods were similar to those used in tropical areas, for other peneid species, and in Japan for this species. Yields of 130 to 270g/sq.m. were obtained, with final average weight of 15g. Marginal costs have been lower than marginal production in assays achieved in 4000sq.m. ponds. Pumps and aerators were necessary to achieve this increase in yield. This method is not appropriate in every part of Atlantic salted marshes

Growth factors in Penaeid shrimp feeding
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Guillaume, Julien; Cruz, R; Cuzon, Gerard; Wormhoudt Van, A; Revol, A.
Some nutrients known as non essential in vertebrates could be essential in invertebrates and could be related to some "unknown growth factors" which were evidenced or suspected, mainly in mollusc or crustacean flesh or meal, by several authors working on different species of crustaceans. A set of experiments was carried out in our laboratory in order to isolate one of these factors found in squid meal.
