CATDOLL : CATDOLL: Can longli fish be bred artificially?

1. Can longfish be artificially bred?

Yes, the artificial breeding of Longli fish in Zhongshan City, my country has been successful, causing quite a stir. The following is a detailed report:

"Longli fish artificial breeding in Zhongshan City has been successful":

"A high-end freshwater fish commonly known as "Tasha" by Guangdong people - the freshwater "Longli fish", has recently been successfully cultivated in Zhongshan City, the first in the province. The wholesale price is nearly 400 yuan per kilogram, but it is still in short supply.

The person in charge of the farm told reporters that he officially started the trial breeding in November last year, and the first batch of more than 2,000 fish were released. The harvest began in April this year, and the average weight was more than half a kilogram. The market wholesale price is nearly 400 yuan/kilogram. As soon as it was put on the market, it was snapped up by restaurants and hotels in Hong Kong, Macao, the Pearl River Delta and other places.

It is understood that the dragonfish is generally wild. Freshwater aquaculture has appeared in Shandong, my country, but due to its high cost and difficulty in raising, many farmers are daunted and have not yet formed large-scale aquaculture. Currently, most of the fish seen on the market are wild, small and expensive. The fish species farmed in Zhongshan City are also introduced from Shandong. The price of finger-length fry is more than 20 yuan per tail.

It is reported that the longli fish has high benefits. After deducting the cost, the profit of each fish weighing more than half a kilogram can reach 100 yuan. At the same time, the breeders also used their own technology to hatch longli fish seedlings and succeeded. In the future, Zhongshan will fully promote the freshwater breeding of longli fish.

2. The difference between longli fish and flounder How to distinguish Basa fish and longli fish

1 The difference between sole and flounder: sole is a type of flounder.

Flounder is a general term for fish of the order Pleurotus sutchuenensis, which includes many fish. There are about 570 species of flounder in the world, which can be divided into 11 families. Among them, sole belongs to the family Glossoglossidae of the order Pleurotus sutchuenensis, so sole is a kind of flounder. According to the current classification of fish, it is mainly semi-smooth tongue sole and striped sole. Semi-smooth tongue sole is commonly called sole or sole, and striped sole is commonly called ox tongue or sole fish, which are all common names for sole. It is a large, warm-temperate near-shore, bottom-dwelling, highly nutritious fish. It contains 13.7 grams of protein and 1.2 grams of fat per 100 grams, and the meat is delicate and delicious.

2 Are longfish and basa fish the same fish? No.

Basa fish is an important freshwater aquaculture species in Southeast Asian countries. It is a freshwater fish, while longli fish is a marine fish. There is a big difference between the two in essence, but in terms of appearance, the appearance and meat color of Basa fish and longli fish after skinning and deboning are very similar. In addition, many shopping malls will confuse the real thing and sell Basa fish as longli fish, which can easily confuse people and give people the illusion that Basa fish is longli fish. But in fact, the market prices of Basa fish and longli fish differ by nearly 10 times, and the taste and nutritional value are also very different. In order to buy authentic longli fish, everyone should pay special attention to identification when purchasing.

3 How to distinguish between Basa fish and Longli fish Basa fish and Longli fish are difficult to distinguish after being frozen. The general identification points are mainly the following two aspects:

1. Look at the appearance and packaging. Whether the packaging of food in my country is imported or exported, there are relatively strict requirements on the surface of the packaging bag and the list of food ingredients. The specific name of the food must be truly marked. Generally, for frozen fish, pay attention to whether the packaging is marked with the word "longli fish" or the English name. If not, it is mostly Basa fish. In addition, pay attention to whether the appearance of the fish is intact, whether the fish has a fishy smell, and whether the meat is fresh.

2. Check the price. As the saying goes, good goods are not cheap, and cheap goods are tricky. Longli fish is produced along the coast of my country, but the output is small and the price is expensive. The current market price is about 200-350 yuan/kg. Most of the basa fish is imported from Vietnam, and the output of artificial breeding is high. The current price of frozen basa fish fillets in the Chinese market is about 20-50 yuan/kg. Compare the prices when buying. For example, the relatively cheap Longqingheli fish is generally basa fish. Don't buy it for cheapness.

4 How to prepare longli fish Ingredients: 2 longli fish, 2 teaspoons of cooking wine, appropriate amount of ginger and garlic, appropriate amount of oil and salt.

practice

1. Wash the longli fish, remove the internal organs, scale it, and cut it into sections. It is recommended to choose fresh ones, and look at the color of the scales, bright red ones are better.

2. Apply 2 teaspoons of cooking wine evenly on the fish body, sprinkle with 1 spoon of salt, depending on your taste. Put it in the refrigerator and wait for 15 minutes, drain the water from the fish, and then pour out the water.

3. Heat the pan with cold oil over high heat. Saute ginger and garlic until fragrant, then add the longli fish into the pan. Do not add water or any seasoning, including salt.

4. Adjust the heat to medium and fry until both sides are golden brown. The frying process takes about 10 minutes and there is no need to cover the pot.

Tips

1. Pay attention to the heat when frying fish and be careful when turning it over, otherwise the fish meat will not form clumping pieces, affecting the appearance.

2. Add some lemon juice when serving to make it taste better.

3. What is the difference between frozen basa fish and longli fish?

‍‍‍‍‍‍With the improvement of people's living standards, many imported seafood have gradually entered ordinary households. Among them, the most common is Basa fish. Compared with other imported seafood, Basa fish is not expensive, and it tastes good and can be cooked in various ways. It is loved by many people. If you go to the supermarket, you will often see frozen Basa fish.

Now that we have talked about the difference between it and longli fish, let’s first learn about Basa fish!

Pangasius

Basa fish belongs to the order Siluriformes, family Panasonicidae, and genus Panasonicus. It is native to the Mekong and Chao Phraya rivers in Indochina. Today, it is an important freshwater aquaculture species in Southeast Asian countries. It is transliterated as "Kabasa" in Vietnamese. Among the Panasonic fish, the Bo's Panasonic catfish and the low-eyed Panasonic catfish are more widely farmed. They have a long body and no scales, a relatively small head, a wide mouth and big eyes.

Basa fish farming areas include Vietnam, Indonesia, Malaysia, Cambodia, etc. Vietnam is the world's largest producer of farmed Basa fish and can be said to be the industry leader. Vietnam's Basa fishery focuses on the export market, which is spread across hundreds of countries around the world. Of course, how can we miss the Chinese market!

The thick-skinned Basa fish is not only large in size, but also has a wide range of diets, is resistant to hypoxia, is not prone to disease, and has low requirements for water quality, making it particularly suitable for high-density farming. It also grows fast, has high yields, and has a meat yield of up to 40% to 50%, making it a high-quality economic fish. The biggest advantage is that it has no small intramuscular spines. The fact that it has a lot of meat and no spines really suits the appetite of many diners!

Basa fish are mostly sold whole and alive in China, while most of the products exported to other countries are in the form of frozen fish fillets, fish portions, fish steaks, fish chunks, breaded fish, fish by-products, etc. Because they contain more fat, they are suitable for processing and sale.

The quality of Basa fish meat depends on the conditions of the aquaculture water and the quality of the feed. Fish meat is generally divided into white, pink (or light pink), and yellow (or light yellow). White is the best, pink is slightly worse, and yellow is the worst.

Longli fish

Longli fish is a type of flatfish, belonging to the order Pleurotus, family Glossopteris, genus Glossopteris, commonly known as tongue fish, flatfish, etc. Among them, the semi-smooth tongue sole is more famous and has been farmed in many areas of my country.

The body of the half-smooth tongue sole is flat and leaf-shaped, and it looks like a long tongue, hence the name "tongue fish". The "crooked mouth and slanted eyes" are all on one side, and are asymmetrical. The scales are relatively small, and the dorsal fin, anal fin, and caudal fin are continuous. The fish can reach 57 cm in length. It has the characteristics of wide temperature, wide salinity, and adaptability to changing environmental conditions. It is a warm-temperate bottom fish, mainly inhabiting the coastal waters of China.

It is a high-quality marine fish, rich in unsaturated fatty acids, delicious, resistant to cooking, no fishy smell, high in protein and rich in nutrition. The most important thing is that it has only one main bone, so the meat yield is relatively high, which is good news for foodies who don't like to pick fish bones! However, there are not many wild half-smooth tongue sole resources, and its breeding industry is also in the emerging stage and needs to be developed. There is a lack of scientific and effective large-scale commercial breeding. Therefore, the price of longli fish in the market is relatively expensive, about 200~350 yuan/kg.

In general, there are still big differences between longli fish and basa fish.

Longli fish is a marine fish with relatively high nutritional value, relatively small scales, relatively high requirements for breeding conditions, and scarce resources.

Basa fish is a freshwater fish that is farmed in large quantities, has a high growth rate, and is long and scaleless, but its meat texture and taste are not as good as those of longli fish.
