Abstract: 

Growth performance of five marine microalgae Isochrysis galbana, Chaetoceros calcitrans, Tetraselmis suecica, Nannochloropsis oculata, Aphanocapsa species was studied under different culture conditions i.e. Conway and f/2 media at 20, 30 and 40ppt salinities (‰). The microalgae culture was undertaken in the indoor facility with 24±1° C temperature, PH 8.7±1 under 24hour photoperiod. Overall highest cell density (56.23million cells/ml) was recorded in Aphanocapsa sp. in Conway medium at 30‰ followed by N. oculata (32.78million cell/ml) in Conway medium at 20‰, whereas lowest value (0.6million cell/ml) was recorded in T. suecicain f/2 medium at 40‰. Overall highest specific growth rate (0.23%) was recorded in T. suecica cultured in Conway medium at 20‰ and the lowest value (0.01%) also recorded in T. suecica in f/2 medium at 40‰. It is further observed that the Conway medium was the best medium for the attainment of maximum cell growth and cell density of the five species studied.
