In a cross-talk, it is said that "there is a lama in the south, carrying 5 pounds of fish in his hand" It is obvious that this thing is related to fish, so it is also the meaning of aquatic products. What is it? He is actually a "dragon li", a fish semi-slippery tongue fish with phosphorus spine ratio scales on the back. The ventral surface is covered with round scales, and the body is very smooth. This is actually a kind of aquatic product cultivated in Guangdong.
Speaking of Guangdong aquaculture, there are really many rich people here, there are many people breeding mandarin fish here, how big is the investment in mandarin fish? Breeding a pond of fish, the daily investment may be as high as tens of thousands of yuan or even tens of thousands, which is what ordinary farmers can afford?
There are very few people who cultivate Dragon Li in the country, so the price is raised. And this fish taste is very delicate, the meat is elastic, the taste is delicious, is the best choice for many Western restaurants, even high-end restaurants, especially suitable for loading forks. Some rich people in Guangdong use this fish at wedding banquets.

This kind of fish is estimated that ordinary people can not eat, although there is farming in the north, but the annual output is less than 2 million catties, in the past two years, the number of aquaculture in the south is increasing, but still can not meet the needs of the whole country, it can be seen that the popularity of this fish, there are really many rich people.
We used to breed more in the north than in the south, but in the past two years, the south has also raised more and more.
< h1 class="pgc-h-arrow-right" > price situation</h1>
Because of the lack of farming, its price has been relatively stable in recent years, but the price is very high. Many people can control the cost of breeding at 40 ~ 50 yuan / kg, you think about the cost is so high, then its market price? Selling a fish in the pond mouth, basically the price of going out of the pond is 60 ~ 70 yuan / kg, and this fish generally grows to 1 to 2 kg out of the pond, the largest can even grow to 7 kg, so a fish can almost earn 40 ~ 50 yuan.
However, the culture technology of this fish is not very mature, and in the past two years it has faced the problems of species degradation and increased pests and diseases. Because after breeding, some diseases will spread vertically, and the effect is better when the fish are raised for the first time, but as the environment of the pond deteriorates, the chance of getting sick increases.
Moreover, the culture cycle of this fish is long, generally more than one year. And it has relatively high requirements for the growth environment, mandarin fish need to live in a living water environment to grow, and this fish requires that the water temperature reach more than ten degrees Celsius, and it needs to constantly change the water every day, and the water quality is slightly worse, and these fish will die. The material in the pond and even the feces can have a very big impact on it.
There are many big bosses in the south who have money but no technology, so they invest money and seek the fisheries of the Chinese Academy of Sciences and some professors to conduct research, because these people have technology, and the investment is generally hundreds of thousands, mainly to study the technology of breeding, as well as the prevention and treatment of diseases and insect pests.
