Constant temperature, mixed vegetables.

1. Constant temperature. There is a greenhouse for fish farming, and the greenhouse maintains a constant temperature of 28°C. This is the most suitable temperature for fish growth. Fish farming will hardly be affected by the external environment. Without a greenhouse, the most suitable water temperature for bass farming is 23-28°C. Without a greenhouse, it is impossible. Keeping the pond water warm can cause bass to stop feeding or eat one meal a few days.

2. Plant a mix of vegetables. Planting vegetables on ponds can take advantage of the large amount of nitrogen fertilizer absorbed during plant growth to effectively solve the problem of eutrophication of water quality. It is impossible to grow vegetables without a greenhouse.
