CATDOLL : CATDOLL: Which fish farming requires heating?

1. Which fish farming requires heating?

The most common small fish on the market, such as tiger barbs, kissing fish, black skirt fish, colorful skirt fish, zebra fish, and tetras, all need heating, and their water temperature should be kept above 20 degrees. As for the scavenger fish, don't think that they are so resistant to low temperatures. There are also issues of different physiques and tolerance of fish, so the water temperature of the cleaner fish must be at least above 16 degrees.

2. How many kinds of fish are farmed?

Grass carp, black carp, silver carp, bighead carp, carp, crucian carp, bream, and bighead carp are farmed fish. These eight fish are all carp fish, warm-water fish, with large spawning capacity and strong reproductive capacity. They can spawn naturally, have sufficient seedling sources, strong disease resistance, a long history of artificial breeding, and mature artificial breeding technology. The breeding method is flexible, and can be intensive or extensive, and can be fed with artificial bait or commercial fish feed.

3. How much land is needed to raise 10,000 toads?

About 40,000 square meters. Let's calculate based on 3,000 toads. We need about 1,000 square meters of land to raise 3,000 toads (one acre, large acre). Mountains, rice fields, ponds, reservoirs, vegetable gardens, orchards, etc., as long as there is soil, toads can be raised. If there is a water source or a wet place, it is better. Pollution sources should be avoided around toad breeding to ensure the quality of toad-based Chinese medicinal materials.

4. What is the salinity required for breeding sand shrimp?

1. Shrimp farming environment

(1) The suitable water temperature for shrimp farming is around 24-27℃, the pH value is around 8-8.4, and the specific gravity of seawater is around 1.020-1.025.

(2) For example, the whiteleg shrimp is a euryhaline shrimp that can grow normally in water with a salinity of 5%-40%, but its more suitable salinity is around 15%-20%.

2. Precautions for shrimp farming

(1) When releasing shrimp fry, the water level needs to be maintained at about 60 cm. In the early stage, add about 4 cm of water every day until the water reaches about 1.5 meters. In the later stage, about 5 cm of water needs to be replaced every day, and live bacteria can be added every day to adjust the water.

(2) During the breeding process, it is necessary to properly operate the aerator, control the transparency and pH of the water, and stabilize the number of algae.

(3) Use water quality protectors regularly to improve dissolved oxygen in water, reduce changes in pH, and reduce the production of ammonia nitrogen and nitrite.

(4) Regularly use microbial inhibitors to promote the balance of beneficial organisms in the water and inhibit harmful bacteria in the water.

(5) Disinfect water bodies regularly to prevent the proliferation of harmful viruses, regularly test water indicators, and promptly handle any abnormalities.

5. How much land is needed to raise 50,000 sheep?

Hello, it is best to have about 2 square meters for one goat! 100,000 square meters of land can raise 50,000 goats!!!

6. How many fish farming bases are there in China?

Fishing ground location: 38°30′N north of Bohai Sea, with an area of ​​about 11,520 square nautical miles

Fishing targets: small yellow croaker, hairtail, prawn, jellyfish, hair shrimp, wing crab, Spanish mackerel, yellow croaker, red sea bream, plum fish, bluefin mullet, hairtail, Spanish mackerel

Nature of the fishing ground: It used to be an important fishing ground for yellow croaker, hairtail, prawns, etc. In recent years, the above resources have declined and no longer form a fishing ground. Only jellyfish, hair shrimp, and wing crabs are produced.

Nature of the fishing ground: It was once an important fishing ground for hairtail, but with the decline of hairtail in the Yellow Sea, the fishing ground has disappeared

Fishing ground location: Northern Yellow Sea, north of 38°00′N, covering an area of ​​about 7,200 nautical miles

Fishing Target: mullet, sand eel, lionfish, bighead carp, mackerel, flatfish, flounder, cod, mackerel, prawns, croaker, yellow croaker, hairtail, ribeye, jellyfish

Fishing ground location: west of 119°00′N in Bohai Sea, covering an area of ​​about 3,600 square nautical miles

Nature of the fishing ground: It was once an important fishing ground for yellow croaker, prawns, blue mackerel, etc., and is currently mainly used for fixed nets and some near-shore operations.

Fishing ground location: 38°30′N south of Bohai Sea, near the mouth of the Yellow River, with an area of ​​about 6,480 square nautical miles

Nature of the fishing ground: It was once the most important fish spawning ground in northern my country. In recent years, due to resource decline, the fishing ground has disappeared, and only some near-shore nets are used to produce small fish, shrimps, swimming crabs, and hair shrimps.

Fishing ground location: Northern Shandong Peninsula, south of 38°30'N, covering an area of ​​about 7,200 square nautical miles

7. Does the sale of farmed fish require a license in accordance with the law?

Fishery farming is the use of waters available for breeding by humans. According to the ecological habits of the breeding objects and the different requirements for the water environment conditions, aquaculture technology and facilities are used to breed aquatic economic animals and plants.

Fishery breeding needs to be carried out in accordance with the unified planning of the country, and applications must be submitted to the relevant fishery administrative department and approval must be obtained before it can be carried out.

8. How much investment is generally required to breed sandworms?

Here we introduce the semi-artificial cultivation of sandworms on tidal flats.

This breeding method is currently the most ideal way to breed sandworms on tidal flats. It requires little investment and yields a lot. An investment of 200 yuan per mu can yield 2,000 to 3,000 yuan per mu.

This breeding method is characterized by low cost and low breeding technology requirements. The only additional management is to observe the safety of the pond and to disperse the seedlings in the pond frequently. The rest is the same as the normal management of the extensive breeding method. However, this breeding method can make the output relatively stable and the economic benefits are very significant. Since the sandworm can reproduce from April to October, and the concentrated egg-laying period is from April to June and from August to October, the annual reproduction volume is theoretically enough to make up for the number reduced by harvesting. However, the climate conditions are different every year, especially the typhoons in the south and the monsoons in the north often take away the newly bred sandworm seedlings or make them die. On the breeding tidal flats, a low dam pond of dozens of acres is built as a natural breeding ground for sandworms. In the breeding season, the water is first fertilized, and then the bodies of the heterosandworms are placed in it, so that a part of the seedlings can be obtained. It only costs a little more than the extensive breeding method, but can achieve several times or even dozens of times the effect.

9. How many acres of breeding land are eligible for subsidies?

1. How many acres of agricultural planting are required to meet the subsidy requirements?

Generally speaking, if agricultural planting meets the standards of a family farm, it will meet the subsidy requirements. The planting subsidy standards in each region will be different. Here we will take you to understand how many acres a family farm must plant to meet the subsidy requirements:

1. If a cooperative raises funds to contract land to plant common crops such as wheat, rice, and corn, it needs to contract more than 100 acres to be considered a family farm. For example, in Guangdong Province, for those mainly engaged in grain crop production, the land lease period is more than 5 years and the operating area is more than 50 acres; for those mainly engaged in fruit production, the land lease period is more than 10 years, and the operating area is more than 30 acres; for those mainly engaged in vegetable production, the land lease period is more than 3 years, and the operating area is more than 30 acres, or the annual income is more than 200,000 yuan; for those mainly engaged in livestock and poultry breeding, the annual output of meat livestock is more than 500 heads, the annual output of meat poultry is more than 10,000, and the annual stock of laying poultry is more than 1,000; for those mainly engaged in aquaculture, the fish pond lease period is more than 5 years, and the operating fish pond area is more than 50 acres; other diversified operations such as combining planting and breeding require land leases of more than 5 years and an annual income of more than 100,000 yuan to be considered a family farm.

2. If you grow crops yourself, you need more than 30 to 50 mu to be considered a family farm. However, according to the previous national land distribution standards, each person was allocated about 8 mu of land, so it is difficult to have so much land, so you have to contract it yourself.

2. Direct grain (rice) subsidies and comprehensive agricultural inputs subsidies

1. The direct grain subsidy and comprehensive agricultural input subsidy standards are 20 yuan per mu for direct rice subsidies and 81.5 yuan per mu for comprehensive agricultural input subsidies.

2. The direct rice subsidy targets the rice planting area approved by the plan; the comprehensive agricultural inputs subsidy targets the planting area of ​​grain crops mainly including rice, corn, wheat, etc.

3. Continue to adhere to the principle of whoever cultivates the land will receive subsidies. In principle, whoever cultivates the land will receive subsidies, but if the contracted land is subcontracted or leased to others, it will be handled according to the contract or lease agreement.

4. Abandoned land, land requisitioned (occupied) for non-agricultural purposes, unoccupied land, private plots, etc. are not eligible for subsidies; land areas that have been clearly requisitioned for non-agricultural purposes this year are also not eligible for subsidies; high-efficiency agriculture is not within the scope of subsidies; and large tracts of grain fields that have been converted into facility agricultural land and are not used for growing grain all year round will not be subsidized.

3. How much government subsidies do farmers receive when they start a family farm?

Due to the different levels of rural economic development in different places, the amount of subsidies given also varies to a certain extent, so you need to consult the local agricultural bureau for details. The approximate subsidy standards are as follows:

1. Subsidy standard in Zhejiang Province: A one-time reward of 100,000 yuan will be given to each municipal-level demonstration family farm.

2. Subsidy standard in Tianjin: Based on the land area, a subsidy of 400 yuan per mu will be given, with a maximum of 100,000 yuan.

3. Subsidy standards in Jiangsu region: Family farms with better performance will be given a reward of 30,000 to 50,000 yuan, and there will be interest subsidy support, up to 50,000 yuan, which can be enjoyed continuously.

4. Subsidy standards in Anhui: Family farms with more than 100 mu of contiguous land will be given a reward of 200 yuan per mu, and small, medium or large family farms will be given an additional 30,000 yuan and 50,000 yuan.

10. Does the land used for breeding farms need to be taxed?

According to relevant regulations, basic farmland cannot be used for animal husbandry. You need to apply to the land department and pay taxes. Article 12 The farmland occupation tax shall be collected by local tax authorities. When the land administration department notifies an organization or individual to go through the procedures for occupying farmland, it shall also notify the local tax authorities at the same level where the farmland is located. The organization or individual approved to occupy farmland shall pay the farmland occupation tax within 30 days from the date of receipt of the notice from the land administration department. The land administration department shall issue a construction land approval certificate based on the farmland occupation tax payment certificate or tax exemption certificate and other relevant documents. Article 13 Taxpayers who temporarily occupy farmland shall pay the farmland occupation tax in accordance with the provisions of these Regulations. If the taxpayer restores the occupied farmland to its original state within the period of approval for temporary occupation of farmland, the farmland occupation tax already paid shall be refunded in full.
