Description
Summary:Starvation and refeeding is an efficient method to excel the quality of the harvesting yields and reduce feeding costs. The purpose of this study was to investigate the effects of low-, moderate-, and severe-intensity starvation on compensatory growth and economic efficiency of Pacific white shrimp Litopenaeus vannamei . Five feeding strategies were designed: feeding every day (C); starving for 1 day followed by 4-day refeeding (T1); starving for 2 days followed by 8-day refeeding (T2); starving for 4 days followed by 16-day refeeding (T3); and starving for 8 days followed by 32-day refeeding (T4). All treatments were fed for a total of 32 days during a 40-day experiment. Low and moderate starvation did not significantly affect growth indices including weight, length, specific growth rate (SGR), feed conversion ratio (FCR), and biomass in T1, T2, and T3 compared with C ( p  > 0.05), while T4 exhibited lower ( p
