Flocs are important biofeeds in the aquaculture crop economy, offering low costs and a low ecological impact.This study was conducted to differentiate the effects on shrimp growth when applying flocs as a dietary supplement compared to no floc supplementation. Dissolved oxygen, temperature, salinity, cumulative growth, growth rates, and the amount of floc administered were measured. The results showed that dissolved oxygen ranged from 9.7 to 3.6 mg/l. Temperature varied between 31.7 °C and 26.4 °C, while salinity ranged from 26 to 28 ‰ in the tank with flocs and from 26 to 30 ‰ in the tank without flocs. Shrimp fed with floc supplementation grew 2 g/30 days, while those without floc supplementation grew 1.6 g/30 days. The growth rate was 0.38 g/30 days for shrimp with floc supplementation and 0.30 g/30 days for those without, with survival rates of 98% for the floc group and 91% for the group without floc. Floc populations ranged from 0.8 to 1.2 million flocs/ml, and an increasing trend in floc population was observed over time. Significant differences were found between shrimp growth in both treatments (p < 0.05).
