Abstract

In this study, we investigated the use of the green algae, Chlorella vulgaris, as an additional food source for larval development, survival rates, and growth performance in Penaeus vannamei nauplii. This research was carried out at a shrimp hatchery situated 50 km South of Chennai city. The experimental group was split into two subgroups. P. vannamei nauplii were provided with experimental diets for a duration of 10 days. The control diet included solely diatom (Chaetoceros calcitrans), whereas the experimental group was provided with Chlorella vulgaris and Chaetoceros calcitrans in alternating feedings. Both groups were also provided with algal feed and artificial feed two times daily. All additional parameters including water salinity (30‰), temperature (31±0.1?), pH (7.9±1), alkalinity (124 mg/L), and hardness (4252±2) were maintained and probiotics were added for both the control and experimental groups. Water quality, feeding habits, and larval stage transformation were observed daily for up to 10 days until all larvae transitioned into post-larvae. The study's findings showed marginally improved survival rates in Penaeus vannamei.
