The nutrient profile of the green alga Golenkinia radiata Chodat includes- carbohydrate (40.39%), protein (13.3%), lipid (12.9%) 64.9 mg total lipid per 500 mg biomass, energy 1385.24 kJ per 100 gm biomass and pigments- chlorophyll a (1.44±0.047 mg/g), chlorophyll b (0.64±0.027 mg/g), total chlorophyll (2.09±0.073 mg/g) and total carotenoids (0.17±0.006 mg/g) (with acetone method) and chlorophyll a (1.76±0.026 mg/g), chlorophyll b (0.45±0.021 mg/g), total chlorophyll (2.21±0.046 mg/g) and total carotenoids (0.20±0.001 mg/g) (with DMSO method). Biomass was rich in carbohydrate content which might have influenced the fish growth in the pond rich of Golenkinia. Green alga Golenkinia has been recorded from different countries of World like - Europe, N. America, S. Africa, Ceylon, Japan and India (Philipose, M.T 1967). Golenkinia radiata has been reported from different water reservoirs but there were absolutely no report on nutritional profile of this alga (Priya Gopinath and Ajit Kumar, 2015, Pathmanapan et al., 2010, Tripathi, 2013, Singh and Balasingh 2012, Tiwari and Chauhan, 2006). Healthy fishes growing in an artificial pond with substantial amount of Golenkinia biomass inspired the idea of its nutritional profiling. Biomass was collected and processed for its proximate composition like carbohydrate, protein, lipid and also the pigments (chlorophyll and carotenoids). This is the first report from Indian species of Golenkinia radiata.
