Cepario de microalgas marinas y producción inicial e intermedia de Nannochloropsis oculata (Eustigmatophyceae) en condiciones controladas de laboratorio OceanDocs
López, A.V.; Bocanfusso, J.J..
Collection of microalgae strains and initial and intermediate production of Nannochloropsis oculata (Eustigmatophyceae) under controlled laboratory conditions. Microalgae, as primary producers of the marine trophic pyramid, make up the first link of the food chain in the aquatic environment. In aquaculture, they are the basis of the whole production of marine fish larvae food such as rotifera, copepods and artemias. Within the “Experimental Mariculture and Biology” Program, at the Instituto Nacional de Investigación y Desarrollo Pesquero (INIDEP), the culture technology of red porgy (Pagrus pagrus) and flounder (Paralichthys orbignyanus) that requires production of microalgae to obtain larvae and juveniles of both species is being developed. The first step...

Croissance et spectre de tailles de six algues utilisees pour la nutrition de larves de bivalves en ecloserie, en culture non renouvelee ArchiMer
Robert, Rene; His, Edouard.
The growth and the size-frequency distribution of six unicellular marine algae, Isochrysis aff. galbana "Tahiti" nom. prov., Pavlova lutheri (Droop) Green, Pseudoisochrysis paradoxa nom. prov., Tetraselmis tetrathele (G.S. West) Butcher, Chaetoceros calcitrans (Paulsen) Takano et Chaetoceros gracilis Schutt have been studied. Most of these species showed an increase in size during the stationary phase of growth. Because these data and anterior ones were achieved in similar experimental conditions, they were ranked by size and their growth performances discussed.

Culture en conditions optimisées de la macroalgue rouge <Gracilaria gracilis> (stackhouse) steentofr et al. dans le lac de Bizerte OceanDocs
Ksouri, J.; Challougui, I.; Mensi, F..
La culture de Gracilaria a été réalisée selon le mode de bouturage dans la partie Nord-Est du lac de Bizerte du 15 Avril au 31 Mai 2006 afin de déterminer l'effet des conditions initiales optimisées sur le rendement final. Ces conditions initiales, sont caractérisées par une culture sur le fond (sur cordes tendues), un poids initial des touffes de 200 g, une distance entre les rangées de culture de 50 cm et un écartement entre les touffes de 30 cm; de ce fait, la densité initiale est de 1,4 kg/m². Au terme de 46 jours de culture, nous avons enregistré un accroissement du poids de 200 g à 1280 g engendrant un taux de croissance spécifique de 4,03 %/j et une densité finale de 9,1kg/m² (soit 91t poids frais/ha).

Etude comparative de l’absorption de l’azote par deux espèces d’algues rouges : <Gracilaria verrucosa> (Hudson) papenfuss, 1950 et Gracilaria <Bursa-pastoris> (gmelin) silva, 1952. OceanDocs
Romdhane, M.S.; Chebil-Ajjabi, L.; El Abed, A..
Afin de mettre en évidence l’aptitude de deux espèces d’algues rouges Gracilaria verrucosa et Gracilaria bursa-pastoris pour le traitement des effluents et leur utilisation potentielle, une série d’expériences a été réalisée ayant pour but d’expliquer le comportement de ces deux espèces d’algues vis à vis de la source d’azote. Dans une première expérience, on a pu déterminer la forme d’azote (N-NH4 , N-NO3) preférentielle pour chacune des deux espèces d’algues cultivées séparément. Elles ont une nette préférence pour N-NH4 et cela pour une même concentration initiale. Cependant, G. verrucosa est un candidat plus performant que G. bursa-pastoris pour l’assimilation des deux formes d’azote. Etant identifié comme source préférentielle, N-NH4 a été utilisé...

Experimental processes of hybridization in the Laminariales of French coasts. ArchiMer
Cosson, J; Gayral, P.
The research has shown that interspecific and intergeneric hybridization is possible in the Laminariales with variable rates according to the species used; these rates were determined precisely only following preliminary study where the rate of parthenogenetic development was evaluated for each particular species. Besides, the results obtained concerning the ecophysiology of the Laminariales and especially the effect of temperature and light on the fertility of the gametophytes, prompt to undertake experimental cultures of the hybrids in order to obtain algae with qualities superior to those of the parents, particularly regarding alginic acid content and growth. The experiments carried out in 1983 concern together the rearing ashore of isolated...

Interet du compteur de particules ZB-ZBI et de l'analyseur C1000 pour la numeration des algues unicellulaires de culture. ArchiMer
Robert, Rene.
Marine unicellular algae growth rates were studied with: a Coulter Counter in conjunction with a channelizer, and a hemacytometer. Compared to the hemacytometer a good precision of the culture density was observed when the Coulter Counter was used in conjunction with a channelizer. Nevertheless care had to be taken when determining the growth of the diatoms.

Large-scale microalgae production for nursery rearing of marine bivalves OMA
De Pauw, N.; Verboven, J.; Claus, C..
The feasibility of large-scale bloom induction of nutritionally suited natural phytoplankton species, to feed a semi-industrial nursery of edible shellfish, built on the Belgian coast, was tested. The outdoor microalgal production unit consisted of four tanks of 100 m² surface each (two of 1 m depth and two of 0.5 m depth), equipped with different mixing devices. The cultures were run as chemostats in which seawater was enriched with commercial inorganic N, P and Si fertilizers. Depending on the season, between 5-10 and 80% of the culture volume could be harvested daily, with algal densities ranging from 50,000 to 500,000 cells per ml. By manipulation of operational parameters such as detention time, nutrient levels and nutrient ratios (N: Si: P), unsuited...

Potentials of converting microalgae into brine shrimp <i>Artemia</i> OMA
Sorgeloos, P..
High densities of brine shrimp <i>Artemia</i> can be cultured in flow-through systems using the effluent of microalgae cultures as a combined source of culture medium and food. It has been proven at the "St. Croix Artificial Upwelling Mariculture Project" that in comparison with the fast growing clam <i>Tapes japonica</i>, brine shrimp assure a much more efficient conversion of plant into animal biomass. It appears from the given examples that microalgae conversion into brine shrimp <i>Artemia</i> offers efficient and economic applications.

Techniques de cultures axeniques d'organismes planctoniques: Un rotifere, Brachionus plicatilis et une algue, Platymonas (= Tetraselmis ) suecica. ArchiMer
The efficiency of different methods for the purification and maintenance of axenic cultures of a rotifer and an unicellular alga is tested. The use of antibiotics seems to be the most suitable method to realize bacteria-free cultures of plankton. No elements prove that the presence of bacteria is necessary for the development of the cultures. Bacteria-free cultures show a physiological evolution of the culture medium is enriched with some nutrients.
