Abstract
Shrimp farming is among the key commercial marine crustaceans in aquaculture. Astaxanthin, a naturally occurring carotenoid, is frequently utilized as a dietary supplement in the culture industry of Pacific white shrimp, Penaeus vannamei. This research was carried out to examine the impact of Astaxanthin supplementation on the occurrence of Blue Shell Syndrome in the post-larval stages of Pacific White Shrimp, Penaeus vannamei, throughout seed production. The research was conducted at a private shrimp hatchery registered with the Coastal Aquaculture Authority situated in the suburban region of Chennai. The experiment was separated into four groups. Control “C” and experiments E1, E2, and E3 (in triplicate). Experimental animals received astaxanthin as a dietary supplement. The findings of this study indicate that the application of “Astaxanthin” 50 ppm as a feed additive for shrimp post larvae of Penaeus vannamei has a notable impact on treating or preventing the onset of “Blue Colour Syndrome” during the development of post larvae. Supplementation with “Astaxanthin” was discovered to improve survival rates, growth performance by facilitating appropriate rostral spine development, and also the ability to endure mechanical stress from the environment.
