    In view of the high demand for brine shrimp larvae in marine shrimp larviculture, due to nutritional richness and practicality in management, several studies have focused efforts on techniques to preserve their biomass, since microcrustaceans are highly subject to decomposition. This study aimed to evaluate the use of canned Artemia salina nauplii in the larval cultivation of Litopenaeus vannamei. An experiment was carried out then a validation in commercial larviculture, Maris Laboratório - CE, both lasting 5 days. The first in 10 L buckets with 2 treatments (AN = fresh brine and AC = preserved brine) and 4 replicates. The validation in 25 m³ tanks, with the same treatments, but without repetitions. The larvae were accompanied by misis 1 to PL2 and evaluated by means of the following analyzes: bacteriological being performed at the beginning, middle and end of the experiment; water quality every day with the parameters of temperature, salinity, pH, ammonia and nitrite; finally, the zootechnical performance through the evaluation of larval quality, larval development index, survival, length and TBI. The data were submitted to ANOVA by the Tukey test for normally distributed data, the differences were reported when (P <0.05). The results were within the recommended standards for the species and there were no significant differences in the evaluations between treatments in any of the experiments. For future work, it is recommended to evaluate the economic viability of the product. Thus, it is possible to replace the nauplii of A. salina in natura by the one conserved in the larval cultivation of L. vannamei, since the test treatment did not alter the evaluated indexes.
