CATDOLL : CATDOLL: What is the fastest payback for farmed species? What is the fastest payback for backyard farming?

1. What is the breeding variety with the fastest return on investment?

I think toad farming pays off quickly. The main income of toad farming chefs comes from the toad venom on the toad's back, which is a famous Chinese medicine with high nutritional value. Farming can make millions a year.

2. Which type of backyard farming can bring the fastest return on investment?

1. Rabbits reproduce quickly.

Due to the advantages of meat rabbits, the gestation period of a female rabbit is about one month, that is, a female rabbit can give birth to a litter of rabbits in one month. The average number of rabbits in a litter is about 6 to 10. If the empty period of the female rabbit is included, a female rabbit can give birth to 6 to 7 litters a year, and the annual number of rabbits is more than 60.

2. The time it takes for commercial rabbits to be marketed is short.

In addition to the rabbit's strong reproductive ability, the time it takes for commercial rabbits to be marketed is also very short.

3. Raising rabbits requires little investment and it is easy to get your money back.

Since rabbits are herbivores and mostly feed on grass, their feed consumption coefficient is very low, generally less than 3. That is, for every 1 kg of weight gain of the rabbit, its feed consumption is less than 3 kg. According to the current rabbit feed price of 2.5 yuan per kilogram and the price of meat rabbits of 16 yuan per kilogram, our farmers can earn about 16 yuan with less than 8 yuan, so it can be said that the profit of raising meat rabbits is still good.

3. Fish breeding techniques?

1.

Stocking time selection: Fish should be released on sunny days when the temperature is not too low. Generally, the temperature should be between 2℃ and 5℃. At this stage, the fish scales are tight and the activity is small. It is not easy to injure the fish during fishing, transportation and stocking operations, which can reduce the morbidity and mortality of fish. It is easy to frostbite the fish on rainy days with low temperature or snowy, frozen and windy weather; when the temperature is too high, the fish scales are loose and the activity is large, which is easy to injure the fish during operation.

2.

Stocking of fish: Before stocking the fish, check whether the drugs have lost their effectiveness after pond cleaning. In early spring, the water temperature is low and the toxicity disappears slowly. Water should be taken in advance and test fish should be released. According to the stocking plan, individual size, density, and matching species and specifications, the fish that can be released at one time should not be released in batches, so that the fish can adapt to the environment, start eating early, and promote growth. At the same time, [Gold Iodine] should be used for drug disinfection when stocking fish.

3.

Feeding at the right time When the water temperature rises to 810℃, fish begin to eat, and the amount of food intake gradually increases with the increase of water temperature, so they should be fed in time. Feed once a day or every other day, and choose to feed at noon on a sunny day; as the water temperature continues to rise, the number of feedings can be increased to twice, that is, feeding once in the morning and once in the afternoon. Feeding should adhere to the principle of four determinations (timing, quality, positioning, and quantity), and the specific daily feeding amount should be flexibly controlled according to the weather, water temperature, and the feeding situation of fish. For grass carp weighing more than 1 jin, it is recommended to feed Da Beinong high-grade expanded feed 8103 in the early stage of feeding; for small grass carp mode, it is recommended to feed Da Beinong microecological juvenile fish special feed [Intestinal Liver Health], and the feeding rate is controlled at about 0.5%1%. This product is rich in nutrients and probiotics, which can quickly repair the fish intestines, restore the physique, and improve immunity.

Four,

Add organic fertilizer to improve the fertility of the water body. Sanyingshuiwang organic biological fertilizer has a long-lasting fertilizer effect. Yizaoyuan promotes algae growth and quickly fertilizes the water. After the fish pond is cleaned, frozen, and disinfected in winter, the fertility of the water body is low. As the saying goes, raising fish starts with raising water, so fertilizing the pond water is particularly important. In spring, it is best to apply organic fertilizer. It is recommended to use biological fertilizers rich in various trace elements [Sanyingshuiwang] or Yizaoyuan, which are rich in trace elements. The specific amount of fertilizer and frequency should be determined according to the quality of pond water and fertilizer.

The general principle is: early spring, large amount and few times, late spring, small amount and many times. Make the pool water green (including blue-green, yellow-green and bean green) or brown (including yellow-brown, reddish brown and tea-brown), the water transparency is moderate, maintained at about 30 cm, the water temperature is low in early spring, it should be controlled at 20-30 cm, the temperature is high in late spring, it should be controlled at 25-35 cm, the water quality should be kept rich, active, tender and refreshing.

5. What are the fastest growing fish?

1. Snakehead

Snakehead fish is a common edible fish, also known as mullet, raw fish, fortune fish, snake fish, firehead fish, etc. It mainly grows in still water or micro-flowing water with dense aquatic plants and fine bottom mud. Snakehead fish is a freshwater fish variety farmed in many areas. Generally, it can reach a weight of 0.5-0.7 kg after 8-9 months of breeding. It is a fast-growing fish with high economic value.

2. Black carp

Black carp is one of the four major fish species in my country and is currently being artificially raised in many areas. Black carp mainly grows in the middle and lower waters, and the most suitable water temperature for its growth is 22-28 degrees. It mainly feeds on snails, clams, mussels, clams, shrimps and insects. It grows very fast and can grow up to about 70 kilograms.

3. Grass carp

Grass carp is also one of the four major carps and the most artificially raised fish species in my country. Grass carp mainly grows in the middle and lower layers of water and in waters with abundant aquatic plants. It is a freshwater fish that feeds on grass. Grass carp grows relatively fast, and the largest individual can reach about 40 kilograms.

4. Catfish

Everyone is familiar with catfish, and they are artificially raised in many areas. Catfish mainly live in the middle and lower layers of rivers, lakes, reservoirs, and ponds. They are a kind of freshwater fish with fast reproduction, strong survival ability, and fast growth. Many people don’t know that they can grow 6 kilograms in half a year. They are also a freshwater fish species raised in many areas.

5. Silver Carp

Silver carp, also known as silver carp, mainly lives in the upper and middle layers of water. In winter, the temperature is low, so it will hibernate in deep waters. Silver carp mainly feeds on plankton in the water. It is a typical filter-feeding fish and its growth rate is also relatively fast.

6. Bighead carp

Bighead carp is a kind of fish that many people like to eat. The chopped pepper fish head we often eat is made of bighead carp. Bighead carp mainly lives in the middle and upper layers of water, mainly feeds on plankton in the water, and grows relatively fast.

7. Wuchang Fish

Wuchang fish is a fish that is unique to my country and is produced in the middle and lower reaches of the Yangtze River. It grows fast and has strong disease resistance, making it a very easy-to-breed fish. In addition, Wuchang fish has tender meat and is particularly suitable for steaming. Steamed Wuchang fish is a traditional dish in Hubei Province and is deeply loved by people in Hubei and even the whole country.

6. Does anyone know what kind of breeding can yield the fastest return on investment in the aquaculture industry?

Breeding with a fast return on investment means fast turnover and short breeding cycle:

Broiler chickens and ducks: Broiler chickens and ducks are now ready for slaughter at around 42 to 45 days old. The breeding cycle is relatively short and they are ready for slaughter quickly. There is also a small broiler duck that is ready for slaughter at around 35 days old.

Meat sheep: In the current sheep breeding market, there is a type of sheep that specializes in fattening. They buy sheep weighing 40 to 50 kilograms for fattening, which takes about three to four months, which is longer than the cycle for broiler chickens and ducks.

Pigs: There are two types of pig fattening. One is to buy weaned piglets and raise them for slaughter after about six months. The other is to buy fattened pigs weighing 70 to 80 kilograms or even 100 kilograms and raise them for slaughter after about four months.

If you want to engage in breeding business, in addition to fast turnover, you must also take into account financial factors, technical factors and your own expertise. Only in this way can you adapt to local conditions, achieve twice the result with half the effort and reach your goals.

7. What are the quality requirements for farmed fish?

1. Fish species

1. Different species of fish have different protein and fat content in their muscles, different meat structures, and large differences in price.

2. Different species of fish have different contents of amino acids that make up the protein in the fish meat, such as lysine, arginine, glutamic acid, aspartic acid, alanine, etc., and the taste is also different.

3. The types and proportions of fatty acids in fish fat, especially the proportion of docosahexaenoic acid (DHA), also vary, resulting in different tastes of fish.

4. DHA is a natural melatonin and an essential nutrient for the human body. Fish with high DHA content include tuna, bonito, salmon, mackerel, etc.

5. The content of the above-mentioned amino acids and DHA in the muscles of marine fish is higher than that of freshwater fish, so marine fish tastes better than freshwater fish.

6. In aquaculture, the selection of breeding species must meet the following conditions: choose suitable breeding species based on the local breeding environment and climatic conditions; examine whether they have market development prospects; the selected breeding species must not have any difficulties in terms of seedlings, feed, etc.; be able to master the feeding and management techniques of the breeding species, and invite breeding experts for regular guidance, etc.

2. Aquaculture water environment

1. Aquaculture requires sufficient water resources, fresh water quality and no pollution.

2. First, establish a farm in a place with sufficient water resources, up-to-standard water quality, convenient irrigation and drainage, and convenient transportation. Secondly, cultivate good water quality. During the breeding process, pay close attention to changes in water temperature, transparency, dissolved oxygen, pH value, etc. to ensure that the water quality always remains "rich, active, tender, and refreshing."

3. Feeding

1. Feed is the material basis for farmed fish to survive. The balance between protein, fat, carbohydrates and vitamins in the feed is crucial. Fish eating high-quality and fresh feed can improve their physiological state and immunity, and increase their survival rate. Fish farmed in this way have good color, normal body shape, strong vitality, firm fish meat and good taste.

2. Feed feeding: select palatable, high-quality, fresh feed according to the physiological characteristics of fish, and strictly follow the "four determinations" principle for scientific feeding; adjust the feeding amount in time according to weather conditions and fish feeding conditions; make full use of the breeding space of the water body, adopt a mixed breeding method of multiple varieties, rationally utilize the natural bait and artificial feed in the water body, improve the breeding water environment, and improve the breeding efficiency.

4. Use of fishery drugs

1. In the process of aquaculture, when cleaning ponds and disinfecting, seedlings and feeding tools, and adjusting water quality, the selection of fishery drugs should be scientific and reasonable, and special attention should be paid to the usage and dosage to prevent the quality of farmed fish from being affected by improper use of drugs.

2. The use of fishery drugs should be based on different aquaculture species and different pathogenic factors. Appropriate national standard fishery drugs should be selected, and treatment should be carried out according to the prescribed dosage, usage method, and course of treatment, and the regulations on drug withdrawal periods should be strictly implemented.

3. In breeding, we should start from the nutritional needs of animal growth, feed hygiene, breeding management and other aspects to reduce the occurrence of diseases and ensure human food safety.

8. What is the largest farmed fish?

grass carp

The fish with the highest annual output in my country is grass carp (one of China's four traditional freshwater farmed fish). The development of the six major freshwater farmed fish species is converging, with grass carp firmly in the first place and bighead carp surpassing carp to enter the top three.

9. How long does it take to pay back the investment in snail farming?

Snail farming pays off in two years Cost of raising one acre of snails

Introduction costs: The first cost of raising snails is the introduction costs. Generally, one mu of land can be stocked with about 60,000 young snails, weighing about 100 kg. The price of young snails is about 4 yuan/kg, so the cost of young snails is 400 yuan. Then, about 1,000 adult snails are released, weighing about 20 kg, and the price is about 6 yuan. Therefore, the total cost of raising snails is about 520 yuan.

Feed input: The main feed for snails is aquatic plants, so we need to cultivate an appropriate amount of aquatic plants. Generally, farmyard manure is used for cultivation. When breeding, the base fertilizer and topdressing fertilizer add up to about 1,400 kg. The price of about 100 kg of farmyard manure is about 10 yuan, so the total investment is only about 140 yuan, and then add 100 yuan of live feed such as earthworms, a total of about 240 yuan.

Miscellaneous expenses: When breeding snails, we also need to invest in disinfectants, water, electricity and other miscellaneous expenses as well as some unexpected expenses, which add up to about 150 yuan.

Because snail farming is generally carried out in rice fields, rice planting requires an investment of about 1,000 yuan. Therefore, based on the above data, we can conclude that the cost of farming one acre of snails is about 2,000 yuan.

2. Profits from raising one acre of snails

Snail income: Young snails are generally released within 1-2 weeks after rice seedlings are planted. Under normal breeding management, they can be released when late rice is harvested. It is impossible for all 60,000 young snails to survive. Assuming 88% survival rate, about 50,000 will survive, weighing about 500kg. The current market price of pollution-free farmed snails is about 6 yuan, so the output value of snails can reach 3,000 yuan.

10. How long does it take to get a payback from farmed kelp?

In the entire life history of kelp, the gametophyte exists for a very short time, generally only about 2 weeks under suitable conditions, while the sporophyte can live for nearly 2 years. Kelp that reproduces naturally on the seabed can generally span three years.

The kelp cultivated on floating rafts in my country can complete a life cycle in one year.

In spring and summer, the sporophyte matures and releases zoospores.

After the zoospores attach, they germinate into gametophytes within a few days. After a short period of growth and development, the gametophytes mature and form eggs and sperm respectively. Soon the female gametophyte ovulates and fertilizes to form a zygote, which germinates into young sporophytes.

The young sporophytes continue to grow and become small kelp seedlings in the autumn. After a winter and spring of cultivation, they grow into commercial kelp.

The difference between kelp and laver

Kelp Laminaria japonica Kelp belongs to the genus Laminaria, class Phaeophyta.

Also known as kelp, kelp, and Jiangbaicai.

Plant morphology: The algae is brown, long and ribbon-shaped, leathery, generally 2-6 cm long and 20-30 cm wide.

The algae body is clearly divided into holdfast, stalk and blade.

The holdfast is rhizoid-shaped, with a thick and short cylindrical petiole and broad, long, ribbon-shaped leaves on the upper part of the petiole.

There are two parallel shallow grooves in the center of the leaf blade, with the middle band in the middle, 2-5 mm thick, and the two edges of the middle band are thinner and have wavy wrinkles.

[Origin and Season] Kelp is farmed along the coasts of Liaoning, Shandong, Jiangsu, Zhejiang, Fujian and the northern part of Guangdong Province in my country. Wild kelp can be found on rocks at a depth of 2-3 meters below the low tide line.

Due to the differences in temperature, light and other factors from north to south, the growth and maturity period of kelp varies. The kelp in the same sea area or on the same seedling rope also matures at different times. Therefore, the harvest period lasts from mid-May to early July.

[Economic Value] Kelp is a vegetable with high nutritional value. Every 100 grams of dried kelp contains: 8.2 grams of crude protein, 0.1 grams of fat, 57 grams of sugar, 9.8 grams of crude fiber, 12.9 grams of inorganic salts, 2.25 grams of calcium, 0.15 grams of iron, as well as 0.57 milligrams of carotene, 0.69 milligrams of thiamine (vitamin B1), 0.36 milligrams of riboflavin (vitamin B2), 16 milligrams of niacin, and can provide 262 kcal of calories.

Compared with spinach and rapeseed, except for vitamin C, its content of crude protein, sugar, calcium and iron is several times or even dozens of times higher.

Kelp is a type of seaweed that is high in iodine.

Cultured kelp generally contains 3-5% iodine, and can reach 7-10%.

The iodine and alginate extracted from it are widely used in medicine, food and chemical industry.

Iodine is one of the essential elements for the human body. Iodine deficiency can cause goiter. Eating more kelp can prevent and treat this disease.

It can also prevent arteriosclerosis and reduce the accumulation of cholesterol and fat.

The sodium alginate in kelp can prevent leukemia and osteomalacia; it also has a hemostatic effect on arterial bleeding, and oral administration can reduce the absorption of the radioactive element strontium-90 in the intestine.

Sodium alginate has a blood pressure lowering effect.

Kelp starch has the effect of lowering blood lipids.

In recent years, it has also been discovered that an extract from kelp has anti-cancer effects.

Kelp mannitol for treatment
