How much is white shrimp per jin at market price? How long can it be frozen, and can dead shrimp be eaten?

White shrimp, also known as hemp shrimp, mud shrimp, lu shrimp, sand shrimp, etc., is a relatively common shrimp in our country. Because of its strong disease resistance, rapid growth and high nutritional value, it is widely farmed, and it is currently sold in markets. So how much is white shrimp per jin at market price now? How long can it be frozen in the refrigerator? Can it still be eaten after it dies?

1. How much per jin?

1. Latest market price:

The price of white shrimp varies greatly depending on the season, place of origin, market, quality and so on. At the place of origin it is generally 20 to 30 yuan per jin, while in markets with more consumers it can reach 80 to 100 yuan per jin. When changes are frequent, it can be said that “the price changes every day”. The reason white shrimp is generally rather expensive is that farming costs are relatively high, which pushes up the selling price of white shrimp.

2. Farming cost and profit analysis (taking one mu as an example):

The annual yield of white shrimp per mu can reach about 3,000 jin. Shrimp seed is stocked once, and no further seed is purchased or stocked for 3 to 5 years. Moreover, the offspring do not degenerate or mutate, and the yield per mu remains unchanged over the long term.

Now, taking the stocking of 120 jin of breeder shrimp per mu as the base for a rough estimate, the number of female shrimp producing offspring per mu per year is:

Stocking amount 120 jin/mu × 20 shrimp/jin = 2,400 shrimp/mu

1,140 shrimp/mu × 200 shrimp/time × 2 times/year = 456,000 shrimp/mu·year

The survival rate of breeder shrimp from spawning to growing into juvenile shrimp is 8% to 30%. Calculated at the lowest 8%, the total annual output of grown shrimp is:

456,000 shrimp/year × 8% = 36,480 shrimp/mu·year

They can be marketed 2 to 3 months after spawning. Each grown shrimp grows to a body weight of 50 grams (about 10 shrimp/jin). The total annual output per mu is:

36,480 shrimp/mu·year ÷ 12 shrimp/jin = 3,040 jin/mu·year

Then the annual gross profit per mu is: 3,040 jin × 8 yuan/jin = 24,320 yuan/mu

Net profit = gross profit 24,320 yuan - seed purchase cost (120 jin × 48 yuan) 5,760 yuan = 18,560 yuan/mu

3. Market demand:

As far as the overall trend is concerned, the price of white shrimp is showing a steady rise. First, the price of white shrimp is gradually becoming more affordable, more and more people can afford to eat it, and demand is rising. Second, due to the impact of previous years, a large number of farmers went out of business and have not yet recovered temporarily, so there is a shortage in the market supply of white shrimp. In addition, white shrimp is now a must-have delicacy for many holidays, and some vendors hoard products waiting for the holidays to arrive. The daily supply is therefore reduced even more.

4. Farming prospects:

Because environmental pollution is becoming more and more serious, natural white shrimp are becoming fewer and fewer, and artificial farming has begun to become the mainstream production method. The farming method for white shrimp is relatively simple, and its adaptability is also strong. It can be farmed by rivers, in ponds, and even more so by the sea. At present, the more common farming methods are basically these three. Coupled with the maturity of farming technology, those currently farming white shrimp generally still make a decent profit.

2. Can it be frozen?

1. How long can it be frozen?

Generally, it can still maintain its original taste and nutrition for seven or eight days. If the shrimp is frozen together with water into a block of shrimp, it can be stored for half a year frozen. If the time is too long, it will dehydrate, and when eaten the texture will not be good and it will not be fresh. After buying fresh large shrimp (or small shrimp), if you feel you cannot eat them all or need to store them for a few days.

2. Freezing method:

(1) Freshly bought shrimp can each be picked up one by one. Before putting them in the refrigerator, sprinkle one tablespoon of white granulated sugar over them, and be sure to mix the shrimp and white granulated sugar thoroughly.

(2) In this way, after putting them in the freezer compartment of the refrigerator and then taking them out, you do not need to worry about the shrimp freezing into icy lumps, and you do not need to thaw them.

(3) Never, just to save trouble, put fresh shrimp in the insulating compartment of the refrigerator. For one thing, shrimp itself is a high-protein food and spoils easily; for another, after being placed in the insulating compartment, the color and form of the shrimp become unsightly, greatly affecting the effect of cooking the shrimp afterward.

3. Can it be eaten after it dies?

1. White shrimp is actually also a kind of seafood, so if white shrimp has died, the situation needs to be treated with caution. Especially shrimp that have been dead for a long time may contain a lot of toxins, so everyone is advised not to ignore these issues in their daily diet.

2. Seafood on the market is basically dead, because most seafood lives in the deep sea. When it is caught, the decrease in water pressure causes the seafood to die, so dead seafood can be eaten, but it depends on whether it is fresh; do not eat dead river fish and other aquatic products, especially river crabs, which are toxic after death, so eat them with caution.
