Abstract: Anabaenopsis sp.is the dominant species in Chenghai lake. Under laboratory condition,the optimum temperature for its growth is 25℃,light intensity is 6000 Lx, photoperiod is 24h,concentrations of NO3-,PO43--P,CO-C andFe3+ are respectively 10.00,1.00,150.00 and 1.00mg·L-1,and PH is 9.0.Its maximum growth rate is 0.817,and the minimum multiplication duration is 0.85 days.The contents of its raw protein,lipid, carbohydrates and ash are respectively 61.25,5.30,20.34 and 8.25%(dry weight),and its amino acid content is 52.63%.
