**Abstract**

This report presented all the referring information about the organic culture of microalgae *Dunaliella salina*, Teodorescu, 1905, produced in organic effluents of Cuban Fishing Industry, and in a synthetic organic medium (MIP-1) and in control (Johnson medium). Here were studied the possibilities possessed by its algae as highadded value, in food industry and pharmaceutical products. A comparative study is offered on 69 bullfights (57 at laboratory scale and 8 in pilot plant), with different combinations and offered an economic valuation on the production of the algal bulk in form of paste in a pilot plant and to industrial scale as well as some possibilities for its use. This report suggest that the culture medium MIP-1 resulted advantageous, which is capable of achieving algae concentrations about 500,000 to 870,000 cell/mL during 15 days of be inoculated, represented a yield between 1,7 and 2,2 g/L on the dry weight base. According to the result data from the culture of this microalgae, to produce 1 kg of wet bulk was calculated a cost that fluctuates between \$6.40 and 6.50, where the culture means in the case of the MIP-1 alone represents \$0.09/m3 of culture medium.
