The effects of feeding commercial feed formulated for semi-intensive systems on Litopenaeus vannameiproduction and its profitability in a hyper-intensive biofloc-dominated system

•Turbidity, total and volatile suspended solids were higher in the treatment with feed designed for semi-intensive system, whereas alkalinity was lower.•Semi-intensive feed treatment required more solids removal, oxygen and bicarbonate supplementation.•Weekly growth, yield and biomass were lower in semi-intensive feed treatment, whereas FCR was higher.•The feed designed for semi-intensive systems (low-cost feed) financially underperformed the feed formulated for hyper-intensive (more-expensive feed).
