Abstract

The aim of this work was to determine the individual growth and survival of Litopenaeus vannamei juveniles (mean wet weight 3.5 ± 0.3 g) kept during 38 days in 1 m3 cylindrical tanks added with 7.1 m2 of artificial substrate at densities between 8-32 organisms m-2. There were no water exchanges, and the only food source was the periphyton growing on the artificial substrates. The final mean weight and survival in the two low-density systems (8 and 16 organisms m-2) were 6.4 g and 91.4-93.2%, significantly higher (P<0.05) than the 4.3-4.8 g and 64.1-65.6% obtained in the two high density systems. Water quality remained within acceptable limits throughout the experiment, indicating that periphyton-based culture in low density closed systems is an environment-friendly and sustainable technique for L. vannamei production.
