Cultures et élevages de masse dans le contexte d'une écloserie-nurserie de mollusques bivalves : les productions phytoplanctoniques et le grossissement des post-larves
Provedor de dados: 5
Autores: Le Borgne, Y.; Marin, J.; Vergonzanne, G.
The hatchery-nursery from the Société Atlantique de Mariculture settled in Barfleur studied within the ECOTRON program set up by C.N.E.X.O. the characteristics of mass cultures for monospecific phytoplancton and of the rearing of oyster spat (Ostrea edulis. Crassostrea giqas) and clam spat (Venerupis semi­decussata) . The maintenance features of the cultures in order to obtain cell densities around 1 million cell/ml. (or 50 g. of dry weight/m3) in containers up to 5000 liters have been established for the main species used in aquaculture (Isochrysis qalbana. Monochrysis lutheri, Tetraselmis suecica. Skeletonema costatum. Phaeodactylum tricornutum. Cyclotella nana, Chaetoceros calcitrans). The spat growth in nursery without providing any cultured food...

Observations françaises sur les nurseries du merlu du golfe de Gascogne au nord-ouest de l'Irlande. Essai de synthèse
Provedor de dados: 5
Autores: Guichet, Roger.
Depuis 1965, 19 campagnes de la Thalassa ont été consacrées en totalité ou en partie à l'étude des nurseries du merlu. Plusieurs de ces campagnes ont fait l'objet de notes au CIEM. Dans ce papier nous nous proposons de tenter une synthèse des observations concernant la répartition des premiers groupes d'âge du merlu et, si possible, de calculer l'importance relative des différentes nurseries

Facteurs contrôlant la croissance de Ruditapes philippinarum dans 4 nurseries de production en Charente-Maritime (France)
Provedor de dados: 5
Autores: Heral, Maurice; Deslous-paoli, Jean-marc; Garnier, Jacqueline; Prioul, Daniel; Heurtebise, Serge; Razet, Daniel.
Different types of pregrowth of the Japanese palourde are compared on the some site. The method by upwelling which is the more common used, to have good growth, requires a compromise between the running and the raised biomass.  Two periods are critical, in the summer the growth of mollusks is stopped because of a decrease in the phytoplanktonic production ;  in the winter, a fall in temperature lessens filtration and stops growth. The results concern clams consummatation rates of particular food (chlorophyll, protids, lipids, glucids) as weIl as the way to supply the decreasing growth : increase of phytoplankyonic production in the summer by recycling waters from nurseries that are loaded with ammoniac and raise winter temperatures by using under-ground...

Essai d'une technique de tri sur post-larves de crevettes en sortie de nurserie et effets sur un grossissement intensif (Penaeus vannamei)
Provedor de dados: 5
Autores: Aquacop,; Boutier, Laurent.
La technique de tri pratiquée avec une maille carrée de 2 mm est bonne et performante par son efficacité et son rendement. Elle est facilement mise en oeuvre sans main-d'oeuvre supplémentaire. Le grossissement des animaux triés montre un effet très positif pour les grandes post- larves avec une réduction de la dispersion et un gain en indice de conversion. Pour les petites post-larves c'est l'inverse avec une augmentation de dispersion et de mortalité dû à une forte présence de queues de lôt.

Compte-rendu d'expérimentation : comparaison entre l'Acal et le Frippak utilisés en nurserie de Penaeus vannamei
Provedor de dados: 5
Autores: Bador, Régis; Boisson, Gilles; Delafosse, Jean-charles; Le Moullac, Gilles; AQUACOP.
Deux séries d'expérimentation ont été menées pour tester les performances en nurserie des deux microparticules mises au point dans le groupe IFREMER/FA/SANOFI : l'ACAL et le FRIPPAK FLAKES. Alors qu'en survie et en croissance en taille (longueur totale) aucune différence n'est mise en évidence, l'ACAL permet de produire des prégrossies de poids sec supérieur et nettement plus résistantes aux chocs de salinité que le FRIPPAK.

Croissance de jeunes palourdes (Venerupis semidecussata) en nurserie et en mer en fonction des conditions d'élevage
Provedor de dados: 5
Autores: Lucas, Albert.
The japanese palourde Venerupis semidecussata was reared in the Bay of Brest, using hatchery reared spat. Experiments were performed with individuals of lenght 2 to 10 mm raised in a nursery, using raceways with slow running water enriched with unicellular algae, And also with individuals of lenght 8 to 20 mm raised at sea in suspended culture. It was observed that growth depends upon four groups of factors : (1) the functioning and equipment of the raceways, (2) the quantity and quality of the food, (3) the temperature and (4) various physico-chemical factors. When the equipment is satisfactory and when the physico-chemical fac­tors are normal for the species in question, the rate of growth depends essen­tially on the quantity of food, provided that the...

Le système immunitaire du bar Dicentrarchus labrax. Immunoglobulines, cellules productrices d'immunoglobulines, ontogenèse applications à une pathologie virale néonatale
Provedor de dados: 5
Autores: Breuil, Gilles.
The sea bass, Dicentrarchus labrax, has been subjected to intensive aquaculture on the Mediterranean cost for ten years. Marine fish hatcheries are key factors in the aquaculture field, and face different pathologies, especially one of viral origin (nodavirus) that could challenge their feasibility. Consequently, we have tried to provide some data on larvae and spawning stocks.   Firstly, we have studied the immunoglobulins, components of the specific humoral immunity, and their role as antibodies. On adult basses, these immunoglobulins are tetrameric molecules with high molecular weight (850 kD), made of heavy (H) - 80 kD and light (L) - 26 kD chains. In the eggs, simplest forms such as monomeric or dimeric are brought to the fore; they are located under...

Production artificielle de naissain de coquilles Saint-Jacques Pecten maximus (L.). Premiers résultats en rade de Brest
Provedor de dados: 5
Autores: Buestel, Dominique; Cochard, Jean-claude; Dao, Jean-claude; Gerard, Andre.
Artificial production from natural spawners could be a way of getting big quantities of spat of Pecten maximus, ln the method described, larval phase (until a size of 250 microns) occurs in a hatchery, post-Iarval phase (from 250 µ until 3 millimeters) in a nursery, and first growth period directly into the sea (from 2 mm to a size of 25-30 mm), The fifst results obtained, production of several thousand of individuals good enough for reseeding, seem to be transposable to a larger scale.
