This study evaluated the use of biofilm in a Litopenaeus vannamei biofloc system using different feeding rates. Shrimp juveniles (0.89 ± 0.35 g) were stocked at 300 shrimp m−3 in 24,150-L tanks. The feeding rates were calculated by considering an expected weekly growth of 1 g week−1 and an estimated weekly mortality of 0.5%. Each treatment corresponded to a different feeding rate, and each feeding...
The natural productivity in biofloc culture systems could be an important source of supplementary food to shrimp, representing savings in artificial feed. The aim of the present study was to evaluate the effects of using different feeding rates for a period of 21days with a posterior re-feeding period in a microcosm system in the presence of bioflocs. Litopenaeus vannamei juveniles (1.14±0.38g) were...
