There are many people who farm tilapia, what time of year is the best time of year to farm tilapia?

Do not choose to put fry in the cold winter, generally around April every year, because the water temperature is not particularly low at this time, generally about 15 degrees can be put fry. Of course, if the climate in the south is not particularly cold, you can do it a little in advance, because tilapia.

It is more afraid of cold, which must be noted, we have some friends in our hometown, and they specialize in raising this kind of tilapia. After all, its cycle is about 5 or 6 months, and two batches can be produced a year, of course, there are many precautions for breeding tilapia, and a little carelessness may lead to the death of tilapia in large quantities, resulting in reduced production, directly causing economic losses. <>

After stocking the fry, we must pay attention to this water level, the depth of this water level is best between 1 and a half meters and two meters, the water level is too shallow to easily affect the temperature change, but also affect the growth of this tilapia. Before, my friend raised tilapia because the water level was too low, probably less than one meter, but when the summer came, the climate was too hot and caused a large number of fish to die, and one year because the water level was not high, the weather was too cold, and some fish were directly frozen to death, so this water level will be very important, at least more than one meter. <>

Raising tilapia requires a lot of oxygen, so it is necessary to carry out oxygen in time when the water level reaches 1.5 meters, or when the water level is relatively high and dense. No matter what kind of fish you raise, tilapia or pond fish.

Fortunately, it is true that oxygen should be carried out in time, about twice a day, if not oxygen, it is easy to cause these fish to lack of oxygen, and it will be easy to die or disease. <>

ForNorthern RegionsThere is an option to stock fry in May to June. The climate in the north is generally colder, the temperature is relatively low, and the water temperature will naturally be lower, so it is most suitable to wait until it is a little warmer to stock the fry and breed them. Before stocking the fry, it is indeed necessary to sanitize the pond and remove some natural enemies that are harmful to the fry.

Tilapia is best farmed in the summer, when the temperature is higher and the water is fresher, and the survival rate is high.

This is the time from May to June when the fish are at their best, and the yield is particularly high, and it is very healthy and nutritious.

It is best to keep tilapia in the spring, the water temperature is more suitable, it is not easy to freeze, and there is a lot of plankton that can be used as bait for tilapia.

In April, it is the best choice to raise tilapia, and the environment is relatively good, which is very suitable for the growth of tilapia.

Because of the cost of tilapia fry introduction, site rental, feed and disease, and daily management, the cost of each catty of tilapia produced is about yuan. 2 yuan catty**, every catty will lose the capital. Tilapia is a tropical fish that is flooded in Guangdong, Guangxi, Hainan and other waters.

Everyone describes it as a fish that can survive as long as there is a mouthful of water, and the tilapia sold in the market is mainly artificially cultivated about 1 2 catties, which can be steamed or boiled.

Tilapia is basically flooded, schools of tilapia can be seen in the stinky ditch, due to the water pollution is particularly serious, few people in Guangdong like to eat tilapia, boiled with a diesel smell. Cheaper than other fish on the market. Tilapia can also survive in heavy metal polluted water, such as many stinky ditches in Guangdong, so wild tilapia is rarely bought.

There are a lot of wild tilapia in Sanya, Hainan, too much more than 2 catties, this kind of fish is not very delicious to eat fresh, and it must be made well and sealed with a dam for 50 days before it will be delicious. If it is artificially raised tilapia, it will be even more unpalatable! Tilapia, widely used in the south, is a freshwater fish, but it can also live in saltwater with different salt contents, and can also survive in shallow lakes, rivers, and ponds.

It can even grow in rice fields, and can adapt to waters with less dissolved oxygen.

Tilapia generally uses plant-based feed, plus it feeds on phytoplankton, so in order to reduce feed costs, it is necessary to fertilize the pond to promote the reproduction of plankton, but the amount of fertilization should be paid attention to, so as not to damage the water environment and affect the growth and quality of tilapia. Tilapia is a tropical fish that is not tolerant to low temperatures and will gradually die when the water temperature drops below 12. Under normal circumstances, except for a few areas in southern China where tilapia can overwinter naturally, measures need to be taken to help it overwinter.

I think that if you want to invest in tilapia farming, then the cost of tilapia farming is about 100,000 or 200,000 yuan, and we should use it reasonably.

Taking a single tilapia farming model as an example, if the whole process is raised, the cost of tilapia farming is about 100 kilograms, and two kinds of tilapia can be raised a year. The fish and shrimp polyculture mode is adopted, and the whole process is fed. Under this model, the cost of tilapia farming is about 10,000 kilograms, and basically one fish can be raised a year.

In the three-dimensional culture mode, tilapia is mixed with four main fish species in the pond, and the cost is about 2-3 yuan kg, which can raise one fish a year.

The cost of breeding is about 5 yuan per catty, and the breeding should also master some professional skills of breeding, and should also change the water regularly, and also need to maintain a very sufficient oxygen, and should also pay attention to ventilation, and the economic benefits are considerable.

The cost of tilapia farming is about 1 catty and 4 yuan, and after removing the cost, the annual profit is more than 10,000 yuan.

The culture cycle of tilapia is about five or six months. Tilapia is usually stocked after the beginning of spring, around mid-April, when the temperature gradually rises and the water temperature slowly stabilizes to 15 degrees or more. When farming tilapia, it is necessary to pay attention to the changes in the water level of the fish pond, as too low the water level will affect the growth of tilapia.

Changes in temperature can affect the fertility of water quality, and when the temperature is too high before lead, fertilizer can be reduced, or new water can be added to adjust the water quality to ensure that there is enough oxygen dissolved in the water. When the water temperature is too high, you can also use an aerator to increase oxygen.

It is necessary to pay attention to the control and prevention of fish diseases, and disinfect the pond and fish at regular intervals. According to the change of weather or the growth of the fish, feed it reasonably. During the breeding period, the fish that have reached the market requirements should be removed from the pond and the density in the pond should be reduced, so that the smaller fish can grow faster.

There are many people who breed tilapia, and tilapia farming is best in spring. The reproductive ability of tilapia. Tilapia mature early, with short spawning cycles, and low reproductive conditions for hatching juveniles in the mouth.

Tilapia can be kept individually or in combination. About 2,000 tilapia can be raised per acre. What does this entail?

In the first 10 days of stocking the fry, 60 kg of quicklime per mu is sprinkled into the pond for disinfection. After 2-3 days, 75 kg of farm manure such as chicken manure and pig manure are applied per mu. Top up the water to 1 meter.

When the water in the pond turns brown, the fry can be stocked. After June, the water surface evaporates greatly and the water level drops, and the high temperature period is the rapid growth period for tilapia. Therefore, it is necessary to raise the aquaculture water level at any time and inject new water so as not to affect the growth of tilapia and delay the time to market.

The high temperature season is the time when tilapia grows most vigorously, and it is also the season when fish diseases are common. Prevention must be done in advance. Every 15 days, sprinkle 15 kg of quicklime water on the whole pool.

It is used for disinfection. Regularly add traditional Chinese medicine to the feed for prevention and control. Timely shipment to reduce the number of ponds.

Because the growth of tilapia is limited by the temperature of the water. Therefore, during the breeding period, especially during the high temperature period, some tilapia that have reached the market size must be taken out of the pond. To reduce the density of the fish pond.

Makes small fish grow faster. This can improve the economic efficiency of the aquaculture industry.

Tilapia, commonly known as African crucian carp, belongs to the order Perch, the suborder Perch, and the family Cichlid. It belongs to tropical fish, its breeding environment and feeding management is relatively special, so now how much tilapia can be raised in an acre of fish pond, what is the breeding density of tilapia, the following is how much tilapia can be raised in an acre of fish pond Tilapia usually lives in fresh water, can also live in salt water with different salt content, and can also survive in the shallow water of lakes, rivers and ponds.

It has a strong reproductive capacity in small water bodies, even in rice fields, and is highly adaptable to water bodies with less dissolved oxygen. Most tilapia are omnivorous and often eat plants and debris in the water. Food Miscellaneous:

Tilapia is a plant-based, omnivorous fish. The contents of the digestive tract of tilapia in ponds are mainly organic detritus and other plant feeds (such as aquatic weeds and commercial feeds, etc.), followed by phytoplankton, zooplankton and a few benthic animals.

<> tilapia, the culture cycle is generally 5-6 months. Tilapia is a kind of tropical fish, the meat is delicious, less spines, high protein content, is one of the main aquaculture aquatic products in our country, the fry are put in the period when the temperature rises after the beginning of spring, generally around mid-April, after the fry can be put by increasing the volume of the water body, reducing the water quality and fertility, using aerators, preventing and controlling fish diseases, etc., to shorten the breeding time of tilapia.

1. How long is the tilapia breeding cycle?

1. The tilapia breeding cycle is about 5-6 months, and the fry are generally stocked in mid-April, and they can be caught in about October.

2. Tilapia is native to Africa, is a tropical fish, in our country is also the main aquaculture products, the meat is delicious and less spiny, the main aquaculture production area is in Guangdong, Guangxi, Hainan and other areas with high temperature, generally pond intensive culture.

3. Cultivated tilapia can shorten the cycle of tilapia farming by increasing the volume of water, reducing water fertility, using aerators, etc., so that tilapia can be marketed in advance.

2. Tilapia farming methods.

1. Site selection of breeding ponds:

1) Generally, you need to choose a pond of 667-1334 square meters, the shape of the pond is rectangular, the bottom of the pond is flat, and the soil at the bottom of the pond is sandy loam.

2) The pond needs to be surrounded by convenient drainage, the pond is pollution-free, facing the sun, the water depth needs to be kept around the time of breeding, and the aerator needs to be equipped to supply oxygen to the fry.

3) Before stocking fingerlings, the fish pond needs to be cleaned 7-10 days in advance, and then the pond water is drained for exposure, and the dry pond is disinfected with lime powder, and fermentation fertilizer needs to be added to cultivate plankton after cleaning and disinfection.

2. Seedling stocking:

1) It is necessary to choose the fry with smooth body surface, strong physique, neat size, plump fish body, and about 5 cm in size, and the fry need to be soaked with 5% salt water or 5-10 mg potassium permanganate solution before stocking.

2) 1 cubic meter fish pond can be stocked with 1 tilapia fry, which can be matched with 50 grams of bighead fish 40-50 per mu, 30-40 silver carp of 30 grams per mu.

3. Feeding management:

1) Tilapia is oxygen-friendly, and daily feeding needs to be equipped with an aerator, which can be equipped with an aeration facility every 5 acres of pool to ensure that tilapia does not appear floating head.

2) before 150 grams of tilapia fry, the use of fertilizer water aquaculture, fertilization once a week, after breeding 2-3 months, tilapia weight of 250 grams per tail, need to change the breeding method, put the full price ratio of good multi-flying fish feed for breeding, in the middle and late stage of tilapia each tail reaches 1 kg, it is necessary to ensure the freshness of water quality, increase the appetite of tilapia, to achieve the purpose of rapid growth.
