Conteúdo:

This study aimed to assess the final body weight, weekly weight gain, yield, apparent feed efficiency,
protein efficiency ratio, and feed intake of the Pacific white shrimp (Litopenaeus vannamei) fed four diets containing different
levels of soy protein concentrate (SPC) as a replacement for fishmeal, reared in a super-intensive biofloc system. Diets
consisted of replacing 209 g kg&#8722;1 fishmeal at 0, 33, 66, and 100% SPC. Shrimp were raised in a biofloc system using twelve
experimental units stocked with 250 shrimp m&#8722;3 under constant aeration (O2>5mg L&#8722;1) and temperature (29±0.5 °C). No
significant differences among treatments were observed based on water quality parameters. Shrimp fed diets with 0 and 33%
substitution exhibited the highest weekly growth (1.88 and 1.79 g per week) and final weights (15.2 and 14.7 g) compared
with shrimp fed the 66 and 100% replacement. A lower feed intake was observed for shrimp fed the 33% SPC diet (3.18 kg per
experimental unit) compared with 0% replacement (3.62 kg). Shrimp fed the 33% replacement achieved a similar performance
and lower feed intake than animals fed diet without replacement.
