first, define the concept of making money. Generally speaking, making money is vague and meaningless, and the rate of making money can be better explained by indicators such as rate of return, profit rate and profit growth rate. For example, there is a big difference in difficulty, feasibility and operation plan between the existing 1 million funds and the 1 thousand funds to earn 5 thousand in one year. There are no huge profits in most varieties of aquaculture. Therefore, it is unrealistic to make a determination to make a protracted war before investing.

factors such as capital, site, climate, technology, target market, investment cycle and risk should be considered in aquaculture. After all these factors related to yourself are investigated and analyzed, we can decide what breed to raise. Blindly following the trend of farming can easily lead to failure.

Livestock and poultry such as chickens, ducks, pigs, cattle and sheep are the main sources of meat for people's daily consumption, and the market demand is very large, but the market fluctuates greatly, the investment is large, and the profit rate is not high. It is necessary to breed on a large scale in order to have considerable profits. In addition, the market cycle of these major livestock is long. If large-scale farming is carried out, it is necessary to have funds to adhere to multi-batch farming. If these batches lose money, the next batch will be earned back. As long as they have the ability to adhere to it, these livestock farming will definitely make money. If a batch loses money, it won't last, and when the next batch market is good, you won't catch up, and you can only die in vain.

The main economic fish, such as herring, grass carp, tilapia, carp, etc., have the same reason as the main livestock, and the market demand is large, and they also need large-scale farming, and only by being able to adhere to multi-batch farming can they make considerable profits. Aquaculture requires high water quality, stable water source, special transportation equipment and flood control. Unconventional fish such as eel, loach, raw fish and seven-star fish have high prices and large profit margins, but the cost is not small.

To do these conventional livestock and aquatic products breeding, factors such as site, sewage discharge, feed and livestock transportation, epidemic diseases, etc. should be considered, especially in some places where the sewage discharge from farms is strictly controlled, so this policy risk must be guarded against. In addition, comprehensive utilization of feces should be done well, so that the benefits can be improved.
