Salmon has a high economic value, so how is expensive salmon farmed and processed?

First of all, the small fry are cultivated, the mature salmon is cut open in the abdomen, the eggs are removed, and then the egg liquid is added, mixed with the eggs, and then they are sent to a professional incubator, after a period of time, the small fry will hatch, and when they are a little older, they will be sent to the indoor breeding tank, where they will grow for 12 to 18 months, and then they will be sent to the sea to be cultured in floating nets. This floating system has a complete feeding system that allows them to grow quickly, an automatic feeding system that automatically feeds at regular intervals, an underwater monitoring system that can monitor the growth of the fish at any time, and a regular check of the water quality to avoid toxins and harmful bacteria that can harm the growth of the salmon.

The first point of breeding is basically in a very large fish pond, the second point is to give some drugs to the salmon in the near future, otherwise it is infected with diseases, the third point is to pay attention to the salmon with good moisture value in the near future, and the fourth point is the main processing, it is processed by special machinery, and then frozen for export.

Salmon is farmed with a lot of shell meat, and then provides a cooler environment for salmon turkey noodles.

OK. Wild salmon live in a highly competitive environment, and they struggle to survive, and it takes three years for them to mature, so they have developed muscle tissue, low fat content, and soft and firm meat.

Farmed salmon lack of natural competition environment and exercise space, feed is composed of high fat, high protein, generally fat and strong, less than 1 year can quickly grow to more than 20 catties, the fish body is fat and tender rich in fat, the fish meat can be seen very obvious white fat line, the taste is relatively soft. Wild salmon is slightly more nutritious than farmed.

Experimental testing found that the nutrition of artificially farmed salmon is also good, the amino acid composition is comprehensive, the total amount of essential amino acids and the mass fraction of flavor amino acids are quite high, and it is a food with high nutritional value.

OK. The term "salmon" we often refer to specifically Atlantic salmon, also known as Norwegian salmon. The vast majority of Norwegian salmon imported into China is farmed. There is already breeding in the country.

OK. 1. Introduction.

Salmon, also called salmon or salmon, is divided into salmonidae and salmonidae. It is one of the most commonly used fish ingredients in Western food. There are different types of salmon in different countries, with Norwegian salmon predominantly Atlantic salmon, Finnish salmon predominantly farmed large-sized red-fleshed rainbow trout, and American salmon predominantly Alaskan salmon.

Salmon generally refers to the salmon of the salmonidae family Pacific salmon, there are many species, such as salmon and humpback salmon from the northeast of China.

Second, breeding conditions.

Structure of the breeding pond.

The breeding pond adopts a shed cement floor structure, and the roof of the shed can be covered with plastic sheeting. Each cement pool in the shed covers an area of 100 square meters, with a depth of 1 5 2 0 meters. There is a water inlet above the cement pool, a drainage outlet below, and a sewage ditch in the middle of the bottom.

2. Water source: It is best to use underground deep well water, if the iron content in the water is high, it should also be equipped with a set of tower aeration and iron removal equipment. Water quality analysis should be done before the water source is used.

3. Charging and power generation equipment: 7 10 kilowatt blower. Also, have another one to spare.

2 Preparation before stocking.

For new cement ponds, water should be soaked for 2 months before they can be used for farming. The old cement pond should be disinfected with fungicide 10 days before the seedlings are stocked before they can be used. The cement pool is filled with water to a depth of 1 meter.

3 Seed stocking.

40 50 Pacific salmon with a size of about 30 50 grams per cubic metre of water are stocked. Generally, after 150 160 days of breeding, the tail weight can reach 900 1000 grams. Fingerlings can be stocked in April in the spring.

4 Feed feeding.

Feed acclimation with pellets. The crude protein content of the feed is 42 45%, and the feed particle size is 3 0 6 0mm. When the water temperature is below 8, feed 2 times a day, 8 a.m

Feed once at 00 9:00 and once at 4:00 pm and 5:00 pm.

When the water temperature is 8 15, feed 3 times a day, and add one more at noon. Each feeding is 80% full, that is, most of the fish swim away.

5. Water temperature control.

Because Pacific salmon is a cold-water fish, the water temperature requirements are relatively strict, and its optimal growth water temperature is 13 15, while the well water temperature is about 8. There are two ways to regulate the water temperature during the rearing period. First, in early spring and late autumn, when the temperature is low, cover the trellis with plastic sheeting to raise the temperature of the pool water.

Second, in the summer when the temperature is high, the plastic sheeting is removed and the temperature of the pool water is lowered by increasing the exchange of well water. Through the above two methods, the minimum water temperature is not less than 5, the maximum is not more than 15, and the water temperature in spring and summer is kept at 13 15.

China is another world's best! The fish farming artifact made in the Yellow Sea has an annual output of 1,500 tons.

Nowadays, salmon is basically kept in captivity.

There must be conditions, suitable temperature, water quality.

Can you keep salmon in freshwater.

There are many kinds of salmon, most of them can not be raised in freshwater, a small number of species can, there seems to be a large-scale freshwater aquaculture success in China, more specifically, the claw machine is weak.

Is freshwater farmed salmon seafood.

No! Seafood, seafood, why not be produced in the sea! In addition, those freshwater farmed fish are not salmon, but rainbow squatting fish!

Does freshwater-raised salmon count as seafood?

Of course, river fresh is not seafood, and it can be a taste after it comes out of seawater and freshwater??? Also, can salmon be kept in freshwater.

Is salmon a deep-sea fish or a freshwater fish?

Salmon, also known as salmon, is a type of deep-sea fish and is one of the commonly used foods. Salmon live in the Atlantic and Pacific oceans, and can be found in the Great Lakes of the Americas and other lakes.

Salmon are born in freshwater, then move to seawater to grow, and then return to freshwater to breed. Salmon swim back to their birthplace to breed using the guidance of the sun and the Earth's magnetic field, and studies have found that 90% of salmon that swim into the stream die in the same stream. Pacific salmon species generally die within a few weeks of breeding.

It is born in freshwater, then moves to the deep sea to grow, and then returns to freshwater to breed. So there's that argument about deep-sea or freshwater fish.

The Chinese have begun to breed salmon, do they still dare to eat this fish?!

Naive, do you think it's okay to breed abroad? Let me tell you, the normal meat of farmed salmon is white, and if you want the fish to turn red, you must feed artificial astaxanthin, whether artificial astaxanthin is safe is not known, and gourmets such as Cai Lan have publicly stated that they will not use farmed ones, so it is recommended that you do not eat them. For more information, please refer to my other question.

Is salmon a freshwater fish? How to raise it, what is the market prospect. What are the breeding technologies, how large is the scale of investment, how much capital is needed, and what conditions should be met.

Salmon looks like migratory fish? What you want to know is pure freshwater rainbow trout or golden trout.

How to survive the freshwater salmon you bought home.

The temperature is controlled below 20, and the dissolved oxygen is above 6ppm, which are the most important, and other pH, ammonia nitrogen, nitrite and other indicators are achieved by changing the water.

Is salmon a freshwater fish or a saltwater fish.

Salmon are salmon that breed in fresh water, grow in seawater, and eventually return to freshwater to spawn and die in freshwater. I don't know if it's fresh water or salt water.

Can salmon be domesticated?

It's best not to keep it domestic, salmon is a precious fish, and we want to protect nature. In addition, salmon is a good edible fish with high protein and high nutrition, if you want to eat it, you can buy it yourself, a big tonic!! It's better to eat less.

1. Species: Salmon is the common name of some salmonids, salmon includes Atlantic salmon, Pacific salmon and other fish, these salmonids are all called salmon. Therefore, before breeding, we should choose good varieties, high-quality varieties can make everyone get twice the result with half the effort in the subsequent breeding process, because most of the artificial breeding is freshwater aquaculture, so the varieties must be suitable for freshwater, and strong disease resistance, otherwise it is not conducive to the economic benefits of the later stage.

2. Water quality: Salmon itself lives in the sea, and the cleanliness of freshwater should be ensured if freshwater is used. Do not take water from certain ponds or rivers at will, and place the salmon with new cement and soak the pond in water for at least two months after drying.

If you are using an old cement pond, you should disinfect the inside of the pond with a fungicide 7-10 days before the fry are stocked, and the depth of the pond should be about the same.

3, density: breeding density can not be too dense, each cubic meter of the maximum stocking of 30-50 grams of salmon 50, because the growth capacity of salmon is very strong, the 50 salmon in 5-6 months after feeding, its weight can reach 1-2 catties, if the breeding density is too dense will make the salmon nutrition uneven, the occurrence of grabbing, can not ensure that each fish has adequate nutrition. Therefore, it is necessary to strictly control the breeding density, and fish fry can be stocked in spring and April every year.

4. Feed: The best feeding of feed is the domestication feeding of granular feed. Roughage must contain nearly half of the protein.

If the water temperature is below 8 degrees, then it needs to be fed at least twice a day, once in the morning and once in the afternoon. If the water temperature is between 8-15, then increase the feeding at least once a day, once in the morning, noon and evening, but it should be noted that each salmon only needs to be 8 minutes full each time.

5. Water temperature: Most of the salmon are cold-water fish in front of the tree, so the requirements for water temperature are stricter, the most suitable water temperature for salmon growth is 13-15 degrees, but the well water needs to be controlled at 8 degrees. During the breeding period, when the temperature is low in spring and winter, it is necessary to increase the thermometer in the pool, which can be covered with plastic bags on the scaffolding to heat up the pool water, and when the temperature is high in summer, it is necessary to use well water frequently to change the water and reduce the temperature of the pool water.

1. The first is to choose the place of breeding, if you want to breed in freshwater, you can go to the freshwater area to take some fresh water to breed, and then try not to pollute the place too much, otherwise it is not suitable for the growth of salmon.

2. The breeding area should be large, if the area is too small, it is very unsuitable for the growth of salmon, and the larger breeding area is not only suitable for the growth of salmon, but also can improve the production of salmon.

3. Then it is to choose the fish to be fed. If you are not very good at mixing fish, you can choose to mix your own salmon fish. There are many on the market, and you can buy them accordingly.

4. Then pay attention to the oxygen content in the water, if the oxygen content is too low, it is very unsuitable for the growth of salmon. Therefore, pay attention to ventilation and water to create a good living environment for salmon.

5. Pay attention to sun exposure and light. Too much sunlight and too much water temperature are not suitable for salmon growth. Pay attention to shading measures to prevent the temperature from being too high.

6. Finally, don't pick too big or too small salmon fry when selecting them, which is not conducive to growth.
