Thank you for the paper about this interesting integration. I have found it
very useful for my work.

I have a comment about table 6, in which you made a comparison of the
economic benefit of the two systems:
I understand that you did not include cost of aeration since it is common
to both systems. However I would like your comments about the importance of
aeration, considering the costs and benefits obtained.

Q.1. Aren't these costs significative? i.e. initial investment and
operation costs.

Q.2. Considering the results and water quality parameters obtained, would
you recommend the use of aerators for a similar stocking density?

Thanks in advance.
