How much is a kilo of razor sticks now? Explain the breeding technology in detail!

Yuzi, also known as Xishi tongue and saber, is a common kind of seafood in China's north and south coastal areas. it is deeply loved by people because of its meat and high nutritional value. at present, many areas are artificially farmed, so how much does a jin of steak cost now? What are the breeding techniques?

First, the introduction of Yuezi:

1. Why did the razor fish come out after sprinkling salt?

Mackerel is not tolerant to high salt, and generally the salt content grows best at 0.4%-2.8%, and the sodium ion in salt will change the living environment, so it will jump out immediately every time salt is sprinkled at the mouth of the cave. This is also the reason why people like to harvest oysters by sprinkling salt.

2. What is the black line in the razor?

The black lines inside the razor are intestinal glands and sand sacs. In the middle of the razor, there is a lot of sand or undigested food and excrement just after eating, so pay attention to it when eating.

2. How much is a kilo of razor sticks now?

The market price is small and expensive, generally about 1320 yuan per jin, but due to the variety, market and sales time, the price will be different to some extent. For example, in Beijing Fengtai District Xinfadi Agricultural products Wholesale Market, the price is about 13.5 yuan per jin, and in Xinjiang Urumqi Beiyuanchun Wholesale Market, the price is about 20 yuan per jin. In Henan Wanbang International Agricultural products Logistics Co., Ltd., the price is about 1425 yuan per jin. In Beijing Dayang Road Agricultural and sideline products Wholesale Market, the market price is about 1215 yuan per jin. If it is bought in the supermarket, it may be about 25 yuan per jin, and if it is the wholesale aquatic products market, it may be about 14 yuan per jin, so the specific price still needs to go to the local market to check.

Third, what are the breeding techniques of mackerel?

1. Site selection and construction: where is suitable for breeding?

Mackerel is suitable for growing in muddy soil with pollution-free, flat and slightly inclined soil, so when selecting land, try to cultivate it in pollution-free shoals or ponds. After selecting the land, build a breeding ground with a length of 50 meters and a width of 3 meters according to the topography, and dig a drainage ditch with a width of about 25cm and a depth of 20cm according to the row spacing of 1 meter for later drainage.

2. Select seedlings: what kind of seedlings should you choose?

Select some seedlings that are lively and active, physically strong, full of shiny shells, symmetrical in size and without broken shells, then soak them in the sea for half an hour, let them spit sand, and finally put them in the seedling field.

3. Release the seedlings: when will they be ready?

(1) Seedling release time: Ching Ming Festival is usually in April in the south and late May in the north.

(2) preparation before seedling release: put the seedlings in a plastic bucket, then wash the sand with sea water, sprinkle with appropriate amount of bleach for 2-3 days, and finally drain water for release. In addition, some tea seed cakes should be sprinkled in the fields to eliminate small fish, shrimps and snails, so as to prevent the young from being eaten.

(3) Seedling release method: two methods can be used to release Sinonovacula seedlings: throwing sowing and sowing, in which throwing sowing is suitable in the place where the site is relatively large, as long as it is directly picked up and scattered evenly in the seedling field, and many people can throw it together at the same time. Sowing is suitable for small plots, generally, you only need to gently pick up the seedlings and sprinkle them hard on the seedlings, so which method you use depends on how big your seedlings are.

4. Field management technology: how to manage it?

(1) soil quality requirements: the mackerel is suitable to grow at the 30cm under the sand layer, and there should be a few centimeters of soft mud on the surface, mixed sediment in the middle and sand in the lowest layer, so it is best to ensure that the soil quality reaches the corresponding thickness when building a breeding land.

(2) Water quality requirements: the water temperature is 332 degrees and the ph value is 88.15 weakly alkaline water, so the water quality should be normal.

(3) Harrow ploughing: after the rake grows for a period of time, the hard soil should be turned deeply and raked fine to ensure the softness of the soil.

(4) Seedling replenishment: after seedling release, the growth should be observed frequently. For places where there are no seedlings or dense seedlings, the seedlings should be replenished in time to ensure the healthy growth of the seedlings.

(5) controlling the temperature: before June, 1500 kilograms of sand per mu can be evenly sprinkled to adjust the temperature, so that the seedlings can grow in a good environment.

(6) Prevention and control of enemy damage: during the period of mackerel culture, attention should be paid to goby, thorn, green crab, water duck and other enemy damage. If the enemy damage has occurred, it can be sprayed with sodium hydride solution.

The above is a detailed introduction of the market price and breeding technology. I hope it will be helpful to all of you.
