Comparación del efecto de la alimentación de post-larvas de litopenaeus vannamei con dietas de balanceado-spirulina y artemia-spirulina

Abstract

This study evaluated the effectiveness of two diets, Balanced-Spirulina and Artemia-Spirulina, on the survival and growth of Litopenaeus vannamei post-larvae. A completely randomized experiment was conducted with two treatments and three replicates each, using 270-liter tanks with 23 post-larvae per liter. Physico-chemical parameters were measured daily, and survival and biomass were evaluated at the beginning and end of the 10-day experiment. Results showed that the Balanced-Spirulina diet was significantly more effective for post-larval survival, reaching 85.4% compared to 54.94% in the Artemia-Spirulina diet. Regarding biomass, although there was no statistically significant difference, a greater numerical increase was observed in the Balanced-Spirulina treatment, increasing from 7.4 g to 24.66 g. It is concluded that the combination of balanced feed and live Spirulina provides a more effective option for feeding L. vannamei post-larvae, outperforming the Artemia-Spirulina diet in both survival and growth. These findings have important implications for optimizing shrimp aquaculture production, highlighting the relevance of selecting appropriate diets to maximize yield and sustainability in post-larval cultivation.
