Resumen

The in vitro digestibility of lipids from Chaetoceros muelleri that were cultured in Guillard medium (F/2) and agricultural fertilizer medium (AF/2) and performance index was examined in enzymatic extracts of Litopenaeus vannamei larvae. The highest enzymatic activity (EA) of lipases was observed in Zoea I (1.53±0.14 EA/10 EU) and Mysis I (1.26±0.01 EA/10 EU (EU are units of enzymatic activity)) when C. muelleri was grown in the F/2 medium. The highest concentration of the unsaturated fatty acids (UFAs) in C. muelleri was observed with F/2 medium (9.96 μg FA/106 cells), and the lowest was obtained with (AF/2) medium (6.68 μg FA/106 cells). The percentage of the total highly unsaturated fatty acids (HUFAs) in Zoea (18.23 %) and Mysis I (F/2=19.32 %, AF/2=20.25 %) larvae was similar between culture media. The performance indices (PI) of shrimp larvae (Zoea I to Mysis I) differed between culture media, with higher values of PI recorded with the F/2 medium-cultured algae (14.3±1.1) with respect to the values with the AF/2 medium-cultured algae (8.0±1.8). We concluded that due to the effect of the nitrogen source in AF/2 medium, C. muelleri cells have a lower HUFA content and L. vannamei larvae experience decreased lipid digestibility and performance index.
