The aim of this study is to evaluate the effects of different fasting periods and refeeding on the growth of Litopenaeus vannamei shrimp. Groups of 15 animals (similar weight) were maintained in plastic tanks for 40 days and 3 treatments were imposed: daily feeding (control), 1 feeding day followed by 2 fasting days (2F) and 1 feeding day followed by 4 fasting days (4F) (n=6). On feeding days, overabundance food was offered in feeding trays and uneaten food removed after 12 h. Shrimp weight was measured every 10 days. Shrimp feed intake was higher in control group than in others, while specific growth rate (SGR) were higher for control and 2F groups, and lower for 4F group. However, the conversion of food into biomass (feeding efficiency) was significantly higher in 2F group than in 4F and control groups. Growth (weight gain/days) was similar amongst control and 2F groups and higher than 4F group. The results indicate that L. vannamei improves feed utilization when fed on the course of short starvation periods.
