The value of farmed salmon from many mountainous areas in Hubei has quadrupled.

After eating salmon for years, I can see what it looks like for the first time.

The standard salmon, also known as Atlantic salmon, is a fish that lives in the deep Atlantic Ocean. It has always been the main ingredient of sushi and sashimi, and it is a veritable high-end delicacy.

But you know, now it, in fact, has long settled in the deep mountains of our province cold pool. Wuhan table on this delicious, many from our Hubei mountain area. At present, Shiyan, Xianning, Enshi and other places in our province deep mountain fishing grounds have its figure. The day before yesterday, the reporter came to Enshi Jianshi County Huaping Town Dahongzhai Village cold water fish breeding base, a look at the deep forest how to breed this traditional marine fish wonders.

"Foreign immigrants" came to the mountain ditch

Dahongzhai Village is 904 meters above sea level, and the cold water fish breeding base is located in a mountain depression surrounded by mountains in the village. The mountains are dense and the roads are difficult. Before the completion of the breeding base in 2011, there was no aquaculture industry here. The breeding base is located here. The first thing to look at is the local clear mountain spring water.

"There is a natural spring hole here. The spring water's temperature is around 11.2 degrees Celsius all year round. It's very suitable for cold-water fish like salmon." Deng Guibin, director of the breeding base, introduced that there are two basic conditions for breeding salmon: one is that the water temperature cannot be higher than 18 degrees Celsius; the other is that the water quality is very clean. "These two conditions are met here." Deng Guibin said,"Before the tap water, the mountain people are thirsty, hold a handful of spring water to drink." There is another reason, Deng Chang finally proudly pointed out,"This is Enshi Prefecture's first selenium-rich village, the fish raised naturally and elsewhere different."

Reporters saw that the entire breeding base covers an area of 45 acres, raising salmon introduced from Norway, rainbow trout, golden trout and other cold water fish. Zhang Xuezhen, an associate professor at the School of Fisheries at Huazhong Agricultural University, said that based on the good natural conditions here, he helped introduce cold water fish such as salmon five years ago. He introduced that salmon can "migrate" deep into the mountains because salmon are migratory fish, so they can grow and develop in fresh water and seawater. At present, many mountainous areas with cold water resources in our province are breeding salmon.

[Farming]

Salmon food is four times more expensive than regular fish food

The treatment of new immigrants like salmon is not a one-off. Its feeding conditions and bait are exquisite.

"The fish are very picky about the water quality. After the rain, the water quality becomes mixed and they stop eating." Deng Guibin, director of the breeding base, said that the base had built a filter tank to solve this problem.

Second, salmon require a much higher oxygen content in the water than normal fish. "The average domestic fish can live at 1 mg per liter of oxygen, but salmon requires 8 mg."

In addition, Deng Guibin also said, Salmon feed requirements are also very high, Salmon seedlings eat feed 28,000 yuan per ton, Adult fish feed also 12,000 yuan per ton,"General fish feed price per ton does not exceed 3000 yuan, By contrast, Salmon feed than ordinary fish feed to 4 times more expensive."

Why expensive? Deng Guibin said, Salmon feed protein content is higher, Also added vitamin C,"Salmon in cold water growth, Consumption of energy is higher, Year-on-year feed protein content requirements are higher." Deng Guibin took out salmon juvenile fish feed and ordinary fish feed to Chutian Metropolis Daily reporter Wen, salmon feed obviously more fishy,"this salmon feed called 'opening feed', that is to say, only this quality feed can make young fish open mouth."

The salmon have to be taken care of even more carefully during farming. "During the breeding process, we must prevent salmon from dying from scratches." Huannong Fisheries College associate professor Zhang Xuezhen said.

According to introduction, salmon generally from seedling to mature market, it takes three years, the size generally grows to three or five jin, and ordinary freshwater fish generally two years can be listed.

[Price]

Four times the price of walking out of the mountain

Salmon cultured in mountainous areas of our province, compared with imported salmon, how about its taste, nutrition and price?

Associate Professor Zhang Xuezhen, who has been engaged in salmon research for many years, gave his answer: Take Jianshi County as an example, the quality of salmon produced here is not inferior to imported salmon, and the nutritional value is higher. "According to my test results, in terms of protein content, the salmon protein content here is similar to that of imported fish, and it is rich in selenium, so it is higher in quality."

In terms of taste, Zhang Xuezhen, who has eaten salmon in many countries, also has the right to speak,"The salmon raised here tastes more refreshing and slippery." Zhang Xuezhen explained that many foreign salmon are also cultured in cages, and the breeding conditions are not much better than those in domestic mountainous areas, especially the salmon imported into China, because of frozen treatment, taste is not as delicious as the live salmon in mountainous areas of our province.

In terms of price, Dahongzhai village cold water fish breeding base director Deng Guibin revealed, Here salmon factory price is 60 yuan/catty, Sell to Wuhan and other big cities, Retail price immediately rose four times, And imported salmon price almost no difference.

Reporters recently saw in a large supermarket near the Central South University for Nationalities that the salmon price here is 236 yuan/catty, and in another large supermarket in Wuchang, the salmon price is 230 yuan/catty. However, many of the salmon sold in these supermarkets are not marked with origin.

[Current situation]

Domestic salmon accounts for 1/3 market

"Now, one-third of the salmon consumed every year in the country is domestically produced." The data given by Associate Professor Zhang Xuezhen shows that the pace of salmon localization is getting faster and faster. "Thirty years ago, Chinese people were content to fill their stomachs, so there wasn't much market for high-end foods like salmon." Zhang Xuezhen said that with the increasing improvement of people's living standards, domestic freshwater aquaculture of salmon has become more and more common in the past 20 years.

The reporter learned from some restaurants in Jianshi that salmon began to walk on the local table in recent years. "Every year before the New Year, many locals come to our base to buy fish." Deng Guibin, director of the market, said that in addition to eating sashimi in line with international standards, locals also love to make it into salted fish for consumption. Ms. Peng, a Wuhan citizen who lives in Wujiashan, loves to eat salmon. She said she calls to order salmon from the base every year."They usually buy 10 pieces at a time. They pack them in cold bags. The fish I receive is alive." Ms. Peng said that the reason why she took a fancy to the salmon produced in the province was that it was alive and kicking.

[Reminder]

Salmon can be raised in both seawater and fresh water

Huannong Fisheries College associate professor Zhang Xuezhen introduced, Salmon can "migrate" deep mountains, Because salmon is anadromous migratory fish, In fresh water can grow and develop.

The standard salmon is Atlantic salmon, but if you go around the market, you will find many fish with different appearance, texture and taste that are called salmon. If you ask the merchant, you will find that these "salmon" have various "prefixes": what Norway salmon, king salmon, red salmon, Alaska salmon and so on. In fact, they belong to the same family as Atlantic salmon, but they are not the same family, and they also have different tastes.
