Abstract

The present study was conducted to estimate the primary productivity of Foy’s Lake in Chattogram, Bangladesh. Gross primary productivity, net primary productivity, and critical respiration were estimated in pre-monsoon, monsoon, and post-monsoon, respectively. Primary productivity was estimated 0.39 gCm-3 h -1 in pre-monsoon, 0.31 gCm-3 h - 1 in monsoon, and 0.61 gCm-3 h - 1 in post-monsoon, respectively. The lowest primary productivity was estimated 0.30 gCm-3 h - 1 in April and the highest primary productivity was estimated 0.61 gCm-3 h - 1 in September. The study showed that the primary productivity varies with seasons indicating that the highest primary productivity was estimated in post-monsoon while the lowest was in monsoon. The data of primary productivity of Foy’s Lake showed that the lake has a good nutrient profile and is suitable for aquaculture.
