The effects of feeding commercial feed formulated for semi-intensivesystems on Litopenaeus vannamei production and its profitability in ahyper-intensive biofloc-dominated system

---

The present study evaluated the production of Litopenaeus vannamei in a high density biofloc-dominatedsystem using two commercial feeds; a less expensive feed (US$0.99 kg−1) formulated for semi-intensivesystems and the more expensive (US$1.75 kg−1) which was designed for hyper-intensive systems. A67-days study was conducted in six 40 m3lined with Ethylene Propylene Diene Monomer membraneraceways (RWs) filled with mixture of seawater (22 m3), and biofloc-rich water (18 m3). Each RW wasstocked (500 shrimp m−3) using juveniles (2.66 g) produced from Taura-Resistant and Fast-Growth breed-ing lines. The study was composed of two feed treatments with three replicates each; the cheaper feed(SI-35) contained 35% crude protein (CP), 7% lipid and 4% fiber while the more expensive one (HI-35)had the same levels of CP and lipid but only 2% fiber. The SI-35 treatment required more solids removal,oxygen, and bicarbonate supplementation than the HI-35 treatment. Weekly growth, total biomass, yieldwere significantly lower in the SI-35 treatment, whereas feed conversion ratio was higher. The economicanalysis indicates that both feeds would be commercially viable, nevertheless, the less-expensive feedfinancially underperformed the other.
