Abstract
Nannochloropsis sp. is one type of phytoplankton which play an important role for larval fish and rotifer production. This study have been done to determine the growth of Nannochloropsis sp. in different light intensity. This research divided into three treatments which are 2.5%, 25% and 100% of light intensity. The results showed the high mean of growth on Nannochloropsis sp. obtained from 100% light intensity treatment with the maximum value 23.33 million cells per mL. The treatment also showed less phosphate and nitrite content in medium culture which were 1.25 mg/L and 2.50 mg/L. However, there was no significance difference (P< 0.05) for growth and nutrient concentration in medium culture on 100% and 25% light intensity treatment. When the 100% light intensity exposed to the heavy rain, the number of cells decline dramatically and become unstable condition. Therefore, this research recommended that Nannochloropsis sp. culture should be done under 25% light intensity for outdoor culture.
