Key Technical Points and Daily Management Methods for Freshwater Fish Farming

The first step in freshwater fish farming is pond clearing: after draining the pond, sun-dry it for half a month, then disinfect and add water; the second step is stocking fry, selecting high-quality fry and disinfecting them before stocking; the third step is feeding, where in addition to special feed, ryegrass can also be fed; the fourth step is the prevention of fish diseases, doing a good job of disinfection and pest control.

Freshwater fish farming species:

1. Grass carp

One of the four major Chinese carps, a typical herbivorous fish. It grows quickly and has a wide range of feed sources, and is a main target of freshwater fish farming in China. Due to the special habits of the grass carp, it has been introduced around the world as a pioneer species.

2. Common carp

It is one of the freshwater fish with the most varieties, the widest distribution and the longest farming history, tolerant of cold, alkali and low oxygen, with extremely strong adaptability, and is an omnivorous fish.

3. Crucian carp

The crucian carp is a common freshwater fish with omnivorous feeding habits, mainly feeding on aquatic plants and plankton. Because its flesh is rich in trace elements and minerals and it is good value for money, it is a delicious dish on the dining table, and it has extremely strong adaptability.

4. Silver carp

The silver carp, also called the white carp or water carp, is one of the four major Chinese carps. It is a typical filter-feeding fish, similar in shape to the bighead carp, with a fierce temperament and good at jumping. It is a freshwater fish relatively suitable for farming, with delicious flesh and rich nutrition, and is deeply loved by people.

5. Snakehead

The snakehead is fierce by nature, with strong reproductive capacity and a huge appetite; it can eat other fish around it, and sometimes even its own young, and it has extremely strong survival ability. It can leave the water to find food, and can survive out of water for up to 3 days, yet it is a delicacy on the Chinese dining table. Moreover, snakehead farming is currently highly profitable, and its farming range in China is also growing.

The technical difficulty of freshwater fish farming is not great, but the choice of farming species and fattening are factors that have a relatively large impact on farming returns. Therefore, before farming freshwater fish, farmers must understand the market conditions well and master fattening techniques well to ensure maximum profit.
