Resumo: | 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 to produce at massive scale is to obtain and maintain the different strains used as live food. At the premises of the Mariculture Experimental Station (INIDEP) microalgae species Nannochloropsis oculata, Tetraselmis sp. and Isochrysis galbana are maintained in an incubation chamber in agar and liquid medium under controlled conditions of light and temperature. Production of N. oculata, the only species cultured at a massive scale, resulted in a total of 30.11 l in the initial stage (January-November 2011) with harvests every 15-20 d, and a final volume of 1,510 1 in the intermediate stage (April-September 2011) with an average concentration registry of 45 x 106 cells ml-1. During both stages cultures were kept at the laboratory under controlled conditions of light and temperature. Inoculates in good physiological conditions derived from the intermediate stage were used to start massive production outside. In this study the methodology used to maintain the collection of microalgae strains of the “Experimental Mariculture and Biology” Program as well as the results obtained from the intermediate massive production of N. oculata under controlled laboratory conditions is described.
