Zhanggongyu is the meat of the fish species Liza haematocheilus. It is known by different names in different regions. Zhanggongyu is the name used in Guangxi and is also known as Zhanggongyu or Huacaiyu in other regions. Zhanggongyu has great medicinal value and is a good supplement for health. Now let's learn about the cultivation methods of Zhanggongyu.
1. Selection and Construction of Ponds
1. Selection of Ponds
It is very important for the cultivation of Zhanggongyu. The most important requirement for the pond is "water". Zhanggongyu requires higher water quality than other fish.
The water source for cultivating Zhanggongyu should be pollution-free groundwater. The water should be warm in winter and cool in summer. Water is where Zhanggongyu grows, so only water conditions that can meet the growth of Zhanggongyu can make it grow well.
2. Construction of Ponds
Zhanggongyu is naturally afraid of light, so in most areas where Zhanggongyu is cultivated, facilities to avoid light are installed in the bottom of the pond for Zhanggongyu to inhabit.
At the same time, when constructing the breeding ponds, fences and fish-blocking facilities will be set up on the water surface and in the water to prevent Zhanggongyu from jumping out of the water, escaping or being invaded by natural enemies.
2. Feeding of Zhanggongyu
1. Selection of Feed
The feeding situation of Zhanggongyu will undergo some minor changes as it grows. When it is still a fry, it can be fed with water fleas, Daphnia, and also animal feed such as egg yolk and minced meat. As Zhanggongyu grows, other animal feeds can also be gradually introduced.
2. Feeding Time
In our province, when breeding Zhanggongyu, there seems to be strict requirements for feeding. Generally, feeding should be done twice a day, in the morning and afternoon. In the morning, it is usually around 8 or 9 o'clock, and in the afternoon, it is around 18 o'clock.
3. Feeding Method
Our breeders are accustomed to cutting the feed into small pieces and controlling the temperature of the feed to be similar to the water temperature before feeding. Generally, the feed is placed on a fish feeding platform for Zhanggongyu to eat.
3. Precautions
1. Regular Water Replacement
Since the water in the pond where Zhanggongyu grows is prone to odor and discoloration, the water in the pond should be regularly replaced. Generally, it is replaced every 10 days to half a month.
2. Regular Inspection
For Zhanggongyu bred in ponds, breeders should inspect them daily. On the one hand, check the feeding situation of Zhanggongyu; on the other hand, pay attention to whether there are snakes, rats, and other enemies around the pond.
3. Regular Cleaning
Zhanggongyu has high requirements for the water quality of its living environment. Therefore, in our region, breeders tend to clean the fish feeding platform, remove food residues and dead fish every day, and remove excessive growth of plants to prevent biological decay and water pollution.
4. Maintain Freshness of Feed
Stale feed will not only affect the water environment in which Zhanggongyu grows but also decrease its appetite and even cause diseases such as enteritis, which is very detrimental to the growth of Zhanggongyu. Therefore, the freshness of feed is very important.
