| 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... |

| 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. |

| Con el fin de proporcionar información sobre cultivos macroalgales en Colombia, se realizaron ensayos de cultivo en medio natural del alga roja Hypnea musciformis. El estudio se desarrolló entre febrero-junio de 2006 en la zona costera de Santa Marta, Caribe colombiano. Los ensayos se hicieron utilizando bolsas de polipropileno suspendidas en una línea superficial en el mar, considerando: lugar (Taganga y Puerto Luz), época climática (seca mayor y lluviosa menor) y tiempo de cosecha (semanal y quincenal). Se obtuvo en promedio total una tasa de crecimiento diaria (TCD) de 2.66 %. No se encontraron diferencias significativas entre los ensayos desarrollados; sin embargo, los mejores resultados se obtuvieron en Taganga en los ensayos semanales durante la... |

| 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). |

| 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... |

| L'algue rouge, Gracilaria verrucosa, a été cultivée, durant le printemps 2009, en mode suspendu à différents emplacements et profondeurs représentant les différences biogéochimiques de la lagune de Bizerte au Nord de la Tunisie. La concentration et la distribution des nutriments (ammonium, phosphate) dans l'eau, ainsi que la salinité, la température, l’oxygène et la transparence de l’eau ont été déterminées. Les méthodes analytiques internationales standardisées ont été appliquées. Les effets du mode de culture, de l’emplacement et de la profondeur sur les rendements en poids, protéines, R-Phycoérythrine et sucres totaux de l’algue ont été étudiés. La croissance de Gracilaria a été similaire dans les différents sites mais plus lente dans les profondeurs... |

| 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... |

| 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. |
