O objetivo do estudo foi avaliar o crescimento e sobreviv那ncia de 1p車s-larvas de Litopenaeus vannamei que receberam embri es liofilizados (EMB) e flocos (FLO) de Artemia como suplementos alimentares a uma dieta microparticulada (DMP). Nos tratamentos T1,T2 e T3, os camar es receberam DMP e ap車s 2h, acr谷scimos de FLO (T1); de EMB (T2); e da mesma DMP, anteriormente, ofertada (T3). No T4, as p車s-larvas foram alimentadas com DMP, mas sem suplementa es posteriores. N o houve diferen a significativa (p %26gt; 0,05) na sobreviv那ncia dos camar es ap車s o per赤odo experimental de 21 dias. Por outro lado, o ganho de peso absoluto (mg peso seco) das p車s-larvas, cuja dieta foi suplementada com BEM, foi significativamente superior (p 0.05) in shrimp survival after the experimental period of 21 days. On the other hand, the absolute weight gain (mg of dry weight) of post-larvae whose dietwas supplemented with EMB (T2) was significantly higher (p %26lt; 0.05) than growth found in the other experimental groups (T1, T3 and T4). Shrimp fed with DMP and EMB obtained a significantly higher absolute weight gain (6.7 mg) than those found in treatments that used DMP and FLO (5.4 mg) or DMP alone (5.8 mg in T3 and 5.7 mg in T4). Theseresults underline the nutritional value of freeze-dried Artemia embryos and recommend their inclusion in the post-larval diet of Litopenaeus vannamei.
