Nutrient availability and light intensity play crucial roles in the population dynamics of Pseudodiaptomus annandalei, a calanoid copepod with potential applications in aquaculture. Current research on copepod cultivation focuses on optimizing culture conditions to enhance productivity, yet challenges remain in achieving stable mass production. This study investigates the effects of varying nutrient levels and light intensities on the population growth of P. annandalei. By understanding how these factors influence population density and egg clutch production, this research aims to provide insights for improving large-scale copepod culturing techniques, ultimately supporting sustainable live feed production for marine hatcheries.
