Abstract: (3 Views)

Taurine is an essential micronutrient for the larval development of Pacific white shrimp (Litopenaeus vannamei), yet its bioavailability in culture systems is often limited by rapid leaching. This study evaluated the effects of liposomal taurine enrichment of Artemia on growth performance, survival, and carcass quality of shrimp larvae during the critical Mysis 3 to postlarva 5 stages. Larvae were obtained from a commercial hatchery and reared under controlled conditions. Five taurine enrichment levels (0, 100, 200, 400, and 600 mg L⁻¹) were tested in triplicate over an 8-day feeding trial. Taurine-enriched Artemia significantly improved larval dry weight, body length, and survival compared with the control treatment (p < 0.05). The highest performance was achieved at 400 mg L⁻¹, resulting in a dry weight of 163.2 µg ind⁻¹ and a survival rate of 84.7%. Carcass composition analysis showed increased crude protein and taurine contents in enriched treatments, while total lipid content remained unaffected. In addition, fatty acid profiles, particularly docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), were enhanced at the optimal enrichment level. Polynomial regression analysis estimated the optimal taurine enrichment level to be approximately 390–405 mg L⁻¹. Overall, the results demonstrate that liposomal taurine enrichment of Artemia is an effective strategy to improve nutritional quality, growth performance, and survival of L. vannamei larvae, with clear implications for commercial shrimp hatchery production.
