How much is the base shrimp market price now? How long can I keep it in the refrigerator? Can you eat after death?

Kei Wai shrimp, also known as sesame shrimp, mud shrimp, Lu shrimp, sand shrimp, etc., is a relatively common kind of shrimp in China. It is widely cultivated because of its strong disease resistance, rapid growth and high nutritional value. At present, it is sold on the market. How much is the market price of Kei Wai shrimp now? How long can I keep it in the refrigerator? Can you eat when you're dead?

1. How much is it per jin?

1. The latest market price:

The price of Jiwei shrimp varies greatly due to season, origin, market, quality and so on. In the producing area, it is generally 20-30 yuan per jin, and in the market with more consumers, it can reach 80-100 yuan per jin, which can be said to be "one price a day" when it changes frequently. The reason why the price of Kei Wai shrimp is generally more expensive is that the cost of breeding is relatively high, thus pushing up the sales price of Kei Wai shrimp.

2. Analysis of planting cost and profit (take one mu as an example):

The annual yield of Jiwei shrimp can reach about 3000 jin per mu, and the shrimp species can be put in one time, and the seed will not be purchased and put into use within 3-5 years, and the progeny generation will not degenerate and mutate, and the yield per mu will remain unchanged for a long time.

Based on the estimate of 120 jin of shrimp per mu, the number of female shrimps per mu is as follows:

The input amount is 120jin / mu × 20 / jin = 2400 / mu

1140 / mu × 200 / time × 2 times / year = 456000 / mu

The survival rate of cultivated shrimp from spawning to young shrimp is 8% to 30%. If calculated at the lowest 8%, the total number of adult shrimp produced annually is as follows:

456000 / year × 8% 36 480 / mu

It can be put on the market in 2 to 3 months after spawning, and the weight of each adult shrimp grows to 50 grams (about 10 / jin). The total annual output per mu is:

36480 / mu / 12 / jin = 3040 jin / mu

The annual gross profit per mu is: 3040 jin × 8 yuan / jin = 24320 yuan / mu

Net profit = gross profit 24320 yuan ~ seed purchase cost (120jin × 48 yuan) 5760 yuan = 18560 yuan / mu

3. Market demand:

In terms of the current overall trend, the price of Kei Wai shrimp shows a steady rise. First, the price of prawns in Kei Wai is slowly becoming more and more popular. more and more people can afford it, and the demand is on the rise. Second, due to the impact of the past few years, a large number of farmers have closed down, which has not been alleviated temporarily, and the market supply of Kei Wai shrimp is insufficient. Coupled with the fact that prawns are now a must for many holidays, some vendors are hoarding products to wait for the holidays. As a result, the daily supply is reduced.

4. The prospect of culture:

Because the pollution of the environment is becoming more and more serious and the natural prawns are less and less, artificial breeding has become the mainstream mode of production. The culture method of base shrimp is relatively simple and adaptable. It can be raised by the river, by the pond and by the sea. At present, there are basically only these three common ways of breeding. Coupled with the maturity of culture technology, the current culture of base shrimp generally have a good profit.

Second, can it be frozen?

1. How long can it be frozen?

In general, seven or eight days can still maintain the original taste and nutrition. If the shrimp and water are frozen together into shrimp pieces, it can be stored for half a year, frozen. If you get dehydrated for a long time, it won't taste good and it won't be fresh. After buying fresh prawns (or shrimps), if you can't eat them or need to store them for a few days.

2. Freezing method:

(1) the shrimp you just bought can be picked up one by one. Sprinkle a tablespoon of sugar on it before putting it in the refrigerator. Mix the shrimp and sugar thoroughly.

(2) if you put it in the freezer and then take it out, you don't have to worry about the shrimp freezing into ice bumps, and you don't have to thaw.

(3) do not save trouble. Keep fresh shrimp in the insulation layer of the refrigerator. Shrimp is a high-protein food that is easy to deteriorate. Secondly, after putting it in the insulation layer, the color and shape of shrimp will become ugly, which will greatly affect the effect of subsequent shrimp cooking.

Third, can you eat when you die?

1. Kei Wai shrimp is actually a kind of seafood, so if the postmortem information of Ki Wai shrimp needs to be treated carefully, especially if it has been dead for a long time, there may be a lot of toxins. Therefore, it is suggested that we should not ignore these problems in our daily diet.

2, the seafood on the market is basically dead, because most of the seafood lives in the deep sea, when fishing, due to the reduction of water pressure, resulting in the death of seafood, so the dead seafood can be eaten, but it depends on whether it is fresh; river fish and aquatic products, especially river crabs, are poisonous and eat carefully after death.
