The article is good and easy to understand. I have a few suggestions about what I miss in the article though. I would like to read more about catches and yield of catfish in its native areas and introduced areas. Is it increasing? Both commercial and recreational sector is interesting in catch and yield of catfish. I would also want to know more about the perception of anglers towards catfish. Preferable catch or not?

I would also want to know more about the effect of catfish on fish populations (especially commercially valuable ones), with citations of sources. Anglers say that catfish negatively affects fish populations. Is that true?

I also want to know more about the view of fisheries managers, aquaculture managers, and fishermen themselves. How to they see the introduction of catfish to non-native areas? Maybe even the view of the public on the introduction of catfish to non-native areas would be interesting.

These are my suggestions. It is what I think would be interesting to add to this article.
