This MS examine some treatment effect on growth and survival of hapas on juvenile sandfish. The subject is interesting as sea-cucumber cultivation is a major issue in recent fisheries. However, there are several issues/pitfalls that have to be solved before publication.
At first this work aims to support mosquito net hapas for floating sandfish cultivation but a comparison with conventional hapas techniques is totally missing. This is a very serious limitation of this study.
Secondly, the methodology and especially the statistical analyses and assumptions are unclear.
Thirdly, a brief state of the art on sandfish cultivation is missing to motivate the study; even the possible advantages of the proposed net are unclear, and
fourthly, a thorough linguistic revision is needed.
More specific comments are included in the annotated MS uploaded.
I strongly suggest to the authors to further work on their MS and their data to present a rigorous contribution on sea-cucumbers cultivation, and re-submit their work.
