I come from Zhengzhou City, Henan Province. A few years ago, my fish ponds were developed everywhere in our area. Most villages are dominated by aquaculture, which is basically divorced from agricultural production, but there are not too many people who can really make money, which is basically the same as that in China, and there is a mess caused by fish diseases and floods.
Therefore, it is recommended that you invest cautiously. If you really want to go to aquaculture projects, it is easy to engage in characteristic aquaculture. In addition, to scale up, retail farming basically has no future.
Personal opinion, for reference only.
