Round 1
Reviewer 1 Report
This is an interesting article on intensive farming systems for Litopenaeus vannamei with innovative adaptations and the use of inactive tanks used for other purposes in aquaculture. It is a well-organized and written article with a good review in the introduction and discussion section. I only detected small errors in the editing of the article.
Line 12. Featured Application: The …….of idle sea cucumber nursery tanks.. Remove the double dot
Line 160. Use italics in Litopenaeus vannamei
In the manuscript, take care of the space between lines.

Reviewer 2 Report
The author researched retrofitting sea cucumber nursery tanks to RAS. The research was conducted at a large scale and could be useful for Litopenaeus vannamei aquaculture. However, the present research was less novelty and academic finding. Therefore, I judged it to " major revision".
Overall manuscripts: what are the novelty and academic points of this study?
Introduction: Please describe the characteristics of sea cucumber nursery tanks. If the author insists the novel of this research is retrofitting sea cucumber nursery tanks, this information is essential.
Line 93 What is the material used for biomedia rings
Figure 5 B. The unit of Salinity should be changed to “‰”.
Figure 7 What happen on days 48-49? Did you change the water? Also, how is nitrate concentration?
Lin267 to 279. This paragraph recommended moving to the introduction section.
