1. Large investment in facilities: The runway fish farming mode needs to invest a lot of money to build aquaculture ponds, sewage pipes, oxygen-increasing pipes and other facilities, and also needs corresponding power facilities, which requires high power.
2. High requirements for aquaculture technology: The runway fish farming mode requires farmers to master certain aquaculture technology, including skills in feeding, oxygen enrichment and sewage discharge. If the culture technology is not in place, it will easily lead to poor growth or illness and death of fish.
