What sturgeon likes to eat, what food do sturgeon eat

Sturgeon is a demersal fish, very narrow diet, is a carnivorous fish, mainly feeds on some small or slow-moving benthic animals in the river, mainly feeds on fish in the ocean, followed by crustaceans, and less molluscs. Juvenile Chinese sturgeon in the estuary area mainly feed on demersal fish such as snakes and pupa, as well as scale shrimp and clams, and generally stop feeding during the spawning period.

Sturgeon is a large migratory fish. In normal times, the Chinese sturgeon inhabits the coastal continental shelf stretching from the west coast of North Korea in the north to the southeast coast of China in the south. After living in the ocean for 9-18 years, when the gonads are close to maturity, they migrate to the Yangtze River in groups, reaching the upper reaches of the Yangtze River, Yibin in Sichuan and the lower part of the Jinsha River to reproduce.

Every summer and autumn, they gather at the mouth of the Yangtze River, trace the river up to the upper reaches of the Yangtze River to spawn in the Jinsha River, and the juvenile sturgeon goes down the river to the East China Sea and the Yellow Sea to grow in the deep water. In spawning populations, males are generally 9-22 years old and females 16-29 years old. The spawning capacity of Chinese sturgeon is also very large, a female sturgeon can produce millions of fish roe at a time, but the survival rate is not high, and the final adult fish are still a minority.

Soon after spawning, the female broodstock begin to descend into the river. The eggs are laid on the rocks or gravel at the bottom of the river, and hatch for about 5-6 days and nights at a water temperature of 17-18 days. Newly emerging larvae with a large yolk sac resembling a tadpole drift down the river and begin feeding after about 12 to 14 days.

In the spring of the following year, the juvenile sturgeon gradually descends into the river, appearing in the area of Chongming Island at the mouth of the Yangtze River from May to August, and after September, the juvenile sturgeon with a body length of 30 cm has left the shallow tidal flats of the Yangtze River estuary and entered the sea to cultivate and grow. Chinese sturgeons can live up to 40 years.

Sturgeon meat is of course delicious.

Compared with expensive deep-sea fish, sturgeon's ** is relatively approachable. Moreover, the meat quality and the nourishment value of the owner are not inferior to that of marine fish. The most important thing is that in recent years, marine pollution has worsened, and individuals are not recommended to eat seafood regularly, which is easy to cause harm to the body.

The meat of sturgeon is also very delicious, whether it is used to make fish soup or grilled fish.

Nowadays, sturgeon is generally farmed in captivity and is a freshwater fish. The meat is comparable to that of salmon, and the sturgeon is full of treasures, from the skin to the internal organs of the fish. The method is the same as the usual way of making fish, and there is nothing special to pay attention to.

In addition, the meat yield of sturgeon is extremely high, so it is very friendly to friends who like to eat fish.

How to make sturgeon delicious:

1. Braised sturgeon.

Wash the sturgeon and cut into cubes. Put oil in the pot and cook it for five years, fry the fish pieces and peel them, add ginger, minced garlic and balsamic vinegar, and mix evenly. Add spicy bean paste.

Add Sichuan pepper powder, light soy sauce, add a little dark soy sauce to color, and add red wine to remove the smell and increase the flavor. Heat water, bring to a boil over high heat, turn to low heat and simmer. When it is almost ripe, add green and red peppers, stir-fry the king and continue to stew.

Sprinkle with pepper and chives and prepare for cooking. Fresh sturgeon is served.

2. Sturgeon stewed tofu.

The sturgeon is washed, abdomen removed, the epidermis is brushed clean with a stiff brush and cut into sections. Prepare ingredients, seasonings. When the pan is hot, add the oil and add the seasoning.

After the seasoning is fragrant, let the fish pieces open and fry them. After the fish changes color slightly, put cooking wine, sweet and sour, soy sauce, diced shiitake mushrooms in turn, and put the soup after the color is adjusted. After putting the soup in the pot, add a small amount of salt according to personal taste, simmer on high heat for 30 minutes, and add the tofu cubes.

Continue to simmer, collect the soup, and prepare for the pot.

What do sturgeons eat? This problem must be the most concerned issue for farmers, because only if the sturgeon eats well can it grow well, and if it grows well, it can achieve better profits. So, what exactly do sturgeons eat to grow well?

What about sturgeon? Let's find out together!

1. What do sturgeons eat.

1. Sturgeon is a perched fish, its diet range is relatively narrow, it eats meat, mainly eats some small or slow-moving benthic animals, mainly eats fish in the sea, crustaceans are second, and mollusks are the least. When the sturgeon in the river is young, it mainly eats benthic fish such as snakes and pupa, as well as shrimp and clams, and generally stops eating during the spawning period.

2. Sturgeon is a carnivorous fish, which can feed on zooplankton at a young age, but it soon grows into a benthic life. Suitable for this type of life, the sturgeon's mouth at this time is convex and lower. The food eaten by sturgeon varies depending on the species, and mainly feeds on crustaceans and small fish.

Sturgeon can be fed directly after they start eating, and in actual production, live bait is often used for sturgeon fry that have just opened their mouths to feed, such as zooplankton or chopped earthworms.

2. How to deal with sturgeon.

1. First remove the scales of the sturgeon and remove the gills. Then take tap water to clean its surface, boil a pot of boiling water, pour it on the body of the fish, and then the body of the fish will be warped with some fine scales, and then use the knife to hang the fish to clean it.

2. After the sturgeon is killed, it should be rinsed, especially the internal organs, and all the internal organs should be cleaned up. Next, pack it in a crisper bag and put it in the freezer compartment of the refrigerator, but be aware that you can only hold one bag per bag, so you can just take it out and thaw it when you want to eat it. There is also a method, that is, after the fish is slaughtered, first take boiling water and barbed wire to clean off the black skin and mucus on the surface of the sturgeon, until the fish body is gray-white and patterned, and then, pour hot water on the fish, however, when scalding the fish, you should grasp the scale, because too much scalding will burn the skin of the fish, it is best to pour boiling water into the basin, carry the tail of the fish in the basin with your hand and scald it a few times, and then scrape off the hard scales on the sturgeon with a knife.

I feel relieved in this way.

Sturgeonfish, i.e. sturgeon. Sturgeon fry eat biological bait, including rotifers, brine worms, daphnia, earthworms, etc.

Sturgeonfish, also known as "cong finger sturgeon", is a class of fishes, sturgeones, and sturgeons. It is produced in various coastal areas and major waters in the north and south, and is a large economic fish. It is one of the few living fossils in the world that lives in water, and is one of the fish with the highest nutrient value of all fish, and the sturgeon eggs can be used as caviar.

The common characteristics of sturgeon are that the body is spindle-shaped, the bones are mostly cartilage, the tail is crooked, the snout is particularly elongated, and the mouth is on the ventral surface of the snout. Sturgeon have a strong food inertia and refuse to eat unfamiliar foods. For example, at the beginning, Min Zhengtong was an edible daphnia and earthworm, and there should be a certain acclimation time when switching to compound feed.

Sturgeon have a narrow diet and eat exclusively meat, mainly eating some small or slow-moving benthic animals in the excavation, mainly eating fish in the sea, followed by crustaceans, and the least molluscs.

Sturgeonfish, also known as "sturgeon", are ichthyidae, sturgeonformes, and sturgeonids. It is produced in all parts of the coast and the major waters in the north and south, and is a large-scale economic fish selling pre-species. One of the few living fossils in the world that lives in water, it is one of the most nutritious fish of all fish, and sturgeon eggs can be used as caviar.

Sturgeon fish with a weight of less than 5 kg farmed in artificial freshwater have better meat quality than precious salmon; Its sashimi tastes fresh, tender, crispy, smooth and refreshing, which is better than lobster; Its cartilage (cartilage of the whole body of the sturgeon), skin, fins, liver, intestines, etc., can be cooked into at least 30 delicious dishes.

The sturgeon is cleaned and cut into three finger-wide segments and divided into two pieces along the backbone; Put the sturgeon pieces in a basin and marinate them in cooking wine, lemon juice, oil, salt, sugar, pepper, etc. for a while; Cut the yellow bell pepper and onion into diamond-shaped pieces, spread a layer of green onions at the bottom of the baking sheet, then spread a layer of bell peppers and onions, put ginger slices and garlic cloves into them, put the sturgeon pieces on top, sprinkle chopped peppers, put onion segments, pour the sauce of the marinated fish, and bake in the oven at 200 degrees for 30 minutes.

Fish may be preferred to pork. After all, the pork we buy in the market is not fresh pork, but the fish we buy can choose different varieties, and the fish we buy back are all fresh fish. One of the fish I'm going to talk about today is called sturgeon.

Many people may not have made sturgeon, or have never eaten sturgeon. Today I'm going to teach you how to make a few swollen sturgeon.

Is sturgeon delicious.

The sturgeon is delicious. Generally, artificial freshwater farming, sturgeon with a weight of less than 10 catties, its meat quality is better than that of precious salmon.

Sturgeon sashimi is tender and crispy; Its cartilage, skin, fins, liver, intestines, etc. can be cooked into at least 30 delicious dishes, which are loved by many consumers.

Nutritional value of sturgeon.

1. High protein content.

The protein content of sturgeon is much richer than that of birds and animals, and its meat and fish eggs contain as much protein as and, respectively. Protein is the basis of life, an important component of cell tissue, and an important component of some active substances in the body, such as enzymes, hormones and antibodies, which can maintain the acid-base balance of body fluids and is very beneficial to the human body.

2. Rich in eight essential amino acids.

Sturgeon is rich in eight essential amino acids: lysine, leucine, isoleucine, methionine, threonine, tryptophan, phenylsterine and valine.

3. Rich in highly unsaturated fatty acids and brain**.

Most of the food animals contain saturated fatty acids, and when too much saturated fatty acids are consumed, blood lipids will rise, making atherogenesis. And sturgeon fat contains DHA and EPA.

Eating sturgeon not only does not accumulate cholesterol in the human blood, but also strengthens brain development and improves brain efficacy.

The sturgeon is slaughtered to remove the internal organs, cut with a flower knife, be careful not to cut off, smear with salt, cooking wine, put green onion and ginger slices and marinate for half an hour.

Pour out the steamed soup, take out the sturgeon, steam the fish soy sauce, light soy sauce, mix the sauce with great flavor, pour it on top, sprinkle with shredded green onions and coriander.

4. Put some shredded green onions and ginger on the steamed fish, and finally splash it with hot oil, the fragrance will immediately overflow, and then you can put it on a plate.

Sturgeon is generally used for steaming, mainly because the steamed fish needs to be prepared better.

Sturgeon mainly eat some live bait and animal feed.

Sturgeon prefer to eat some live bait because of their carnivorous fish. Wild sturgeons like to eat some small fish, small shrimp, small crabs, daphnia, etc. Juvenile sturgeons will eat some cladopods, copepods, midges larvae, and aquatic oligochaetes.

Captive-bred sturgeon can be fed some shrimp, snails, mussels, bloodworms, earthworms, daphnia, synthetic feed, etc.

These foods are very rich in nutrients and are of great help to the growth and development of sturgeon. However, different species of sturgeon have different habits and prefer different foods. When raising sturgeon, you can choose the food you feed according to their habits, which will help them more.

Sturgeon farming techniques

1. Space: The size of sturgeon is relatively large, and a larger fish tank needs to be prepared when artificially breeding, so as to ensure that their activity space is sufficient. If conditions don't allow, at least prepare a space that is twice the size of a sturgeon.

2. Environment: Sturgeon does not have high requirements for water temperature and water quality, as long as the water temperature is above 20, they can live normally. The pH value can be controlled around the same level, and the frequency of water change can be determined according to the cleanliness of the water quality.

3. Oxygen: Sturgeon have a high demand for oxygen, and you need to install an oxygen pump when breeding in captivity, so as to ensure that the oxygen in the water in which they live is sufficient.
