- Abstract
Effect of various environmental stresses on the fatty acid (FA) profile of benthic harpacticoid copepod (Pararobertsonia sp.) was checked In vitro. Samples were exposed to different pH (5, 7 and 9) and salinity (15, 20, 25, 30 and 35 ppt) at constant temperature 25°C for 30 days. After the treatment, different fatty acid levels were determined using Gas Chromatography and Mass Spectrometry (GC-MS). Results clearly indicated the positive influence of the combined effect of environmental parameters on the fatty acid content in experimental samples. The detected FAs were ranging from C5-24. Palmetic and oleic acids were in higher percentage in all the experiments. Results clearly indicated that pH7:25ppt & 35ppt at 25°C ambient water temperature would help in producing copepods (Pararobertsonia sp.) that expresses rich fatty acid profile with high EPA/DHA ratio.
