Abstract: Spirulina has been so popular in the present world’s context due to its high nutritional value. Due to its primitive and good quality protein, vitamins, essential fatty acids contents, antioxidant pigments, antimicrobial activity, and anticancer properties Spirulina which is a fast-growing cyanobacteria have been used as a possible alternative source of protein for the fish culture. As it is known that, the biomass of Spirulina is nutritionally rich in protein it may be used as a splendid alternative to fish protein to reduce the cost of feed. It has its tremendous attributes to replenish the required amount of protein dwindling the excessive cost as 70% of the total operating costs belongs to the feed supplement in terms of whole culture period. The study was conducted on the feasibility of Spirulina culture assessing its growth pattern through lab scale culture. The experiment was carried out to evaluate the lab scale cultivation of Spirulina by using different substrates having different concentration of Fish Meal Medium (FMM) each with the three replications T1 (15% FMM), T2 (20% FMM), T3 (25% FMM) & T4 (Kosaric medium), respectively. The growth rate of S. platensis was significantly higher in T4 (p<0.05) than the other treatments (T1, T2 & T3). It might be due to the availability of more nutrients in KM than various concentrations of FMM. On the other hand, the growth rate was higher in concentration of 15% FMM than other concentrations of FMM. The physico-chemical parameters i.e., temperature 28.00-29.39 oC, pH: 9.33-9.44, dissolved oxygen (DO): 5.97-6.58mgl-1, measuring the voltage between a pH sensitive glass electrode (MVPH): 129.70-149.47, total dissolved solid (TDS): 1025.00-3862.00, electric conductivity (EC): 1899.17-5726.67, hectopascal pressure unit (hpa %): 1009.50-1017.33 were observed in the optimum level.
