Experience of intensive rearing of micro-alga Spirulina platensis
Experiments of cultivation of micro-alga spirulina (Spirulins platencis) in YugNIRO, Kerch, Ukraine are described. Alga culture from Institute of Fisheries, (Burgas, Bulgaria) were used. The cultivation was carried out from May to October 1992 and 1993 in open plastic tanks with water surface from 1.2 m super(2) to 4m super(2). Aeration and mineral fertilisers were applied. Both in greenhouse and outdoor culture, temperature and intensity of illumination are major factors controlling the productivity of Spirulina. Productivity of Spirulina grown under different greenhouse conditions may be on the order of 0.1-0.3 g/dm super(3). In outdoor culture of Spirulina the highest growth of its biomass was recorded from a plastic pool 3.2 m super(2) in area, with 25 cm culture medium thickness. At temperatures below optimal for this species (16-27 degree C) the harvest over four days of cultivation was 15 g /m super(2). Over 15 days of continuous Spirulina culture in a greenhouse, the yield was, on an average, 5 g/m super(2) from an area of 20 m super(2). From plastic pools in the southern and western sides of the greenhouse the yield was up to 25 g/m super(2). In 1993, the productivity of this Spirulina species under greenhouse conditions ranged from 8.7 to 33.0 g/m super(2), with a mean value of 19.2 g /m super(2).
