Correction: Blatt et al. Environmental Sustainability of Nile Tilapia Reared in Biofloc Technology (BFT) System: Evaluation of Carbon, Nitrogen, and Phosphorus Dynamics and Indicators of Sustainability. Sustainability 2025, 17, 5670

In the original publication, there were errors in the reported values of water use in the Biofloc Technology (BFT) system. The authors would like to make the following corrections in the published paper [1]. The changes are as follows:

• In the Abstract, the water use was incorrectly described as 0.0074 m³/ton. The correct value is 135.3 m³/ton.
  The following is the original sentence in the Abstract:
  Water use was minimal (0.0074 m³/ton).
  This has been replaced with the correct sentence as follows:
  Water use was 135.3 m³/ton.
• On page 9, Table 4, the water use (m³ ton⁻¹) in BFT was erroneously listed as 0.0074 ± 0.0005. The correct value is 135.30 ± 8.20. Authors would like to change the value of use of water (m³ ton⁻¹) in Table 4.

On the same page 9, the following is the original paragraph:

In the ‘resource use’ category, BFT demonstrates negligible water consumption com-pared to the production of tilapia in cages; however, it requires more space and energy (Table 4).

This has been replaced with the following corrected paragraph:

In the “resource use” category, BFT exhibits higher water consumption, use of space and use of energy than Nile tilapia production in net cages (Table 4). Nevertheless, BFT remains consistently characterized as a low-water-demand technology when compared to other aquaculture production systems.

The following is the original version:

In the present study, it was estimated that juvenile tilapia reared in BFT require an average volume of 0.0074 m³ per ton.

This was replaced with the following corrected version:

In the present study, it was estimated that juvenile tilapia reared in BFT require an average volume of 135.3 m³ per ton.

The authors state that the scientific conclusions are unaffected. This correction was approved by the Academic Editor. The original publication has also been updated.
