Astaxanthin provides health benefits to humans and that is also used in mariculture feed to enhance tha color of salman flesh. The vegetative stage optimization is one of the difficult and most important step in astaxanthin production process. The potent strain of Haematococcus pluvialis Flotow collected from Pithoragarh district, Uttarakhand, India. Pithoragarh is located at 29.58°N 80.22°E. It has an average elevation of 1,514 metres (4,967 feet). In the present study, we optimised the effect of pH, light, NaNO3, K2HPO4, NaHCO3 for enhanced the vegetative growth of Haematococcus pluvialis. The maximum level of growth rate, chlorophyll a, chlorophyll b and carotenoid were observed in pH – 7.0, light - 12 hrs Light : 12 hrs Dark, NaNO3 – 0.3 M, K2HPO4 – 0.08M, NaHCO3 – 0.08 M. on 40th day of incubation period. | | Keywords : | | - NaHCO3
