Is canvas fish pond suitable for long-term fish farming? In real life, if you want to breed a large number of fish, it is natural to have a good fish pond, and canvas fish ponds are also common fish ponds. Let's share with you whether canvas fish ponds are suitable for long-term fish farming.

Is the canvas fish pond suitable for long-term fish farming 1 1. Is canvas fish pond suitable for long-term fish farming?

Canvas fish ponds can be kept for a long time if they are only used to feed fish, but due to its many limitations, there are not many species to choose from. Usually only some fish can be raised, and it is not easy to install other equipment and change water. Its biggest advantage is its lower cost. There are at least dozens of fish tanks and thousands of good ones, while canvas fish ponds are only about 10 yuan per square meter.

Second, what are the shortcomings of the canvas fish pond?

1, difficult to manage: the primary problem of canvas fish ponds is difficult to manage. Unlike ordinary fish tanks, it is difficult to install filters and other equipment, so the water quality is very problematic and water needs to be changed frequently. Moreover, if green algae grow, it is not easy to clean up and the water temperature is difficult to control.

2, poor ornamental: ordinary glass fish tanks are transparent, and you can see the activities of fish from all directions, while canvas fish ponds cannot. Generally, you can only look down from the top. In this case, viewing is limited, people don't know much about fish, and they may even miss the opportunity to treat diseases.

3. Species restriction: As mentioned above, the canvas fish pond can only be seen from above, so the raised fish must also be seen from behind, such as goldfish and koi fish. Of course, if you use this fish pond, you can also raise some edible fish, such as perch and yellow catfish.

Is canvas fish pond suitable for long-term fish farming? The raw material of canvas fish pond is PVC plastic-coated cloth, which is waterproof, wear-resistant and sun-resistant. Looking at this reservoir alone, the service life is still relatively long, which seems to be in line with the word long-term. Then, let's look at the choice of fish. Are all the fish in canvas ponds suitable for long-term culture? The answer is definitely no. Different fish have different requirements for their growing environment.

The most important thing is the water quality problem that cannot be ignored. Canvas fish ponds are different from other open-air fish tanks, and the water temperature is difficult to control. Moreover, canvas fish ponds are not transparent, and their ornamental value may not be as good as that of ordinary fish tanks. If the fish has some problems, it may not be found in time.

Because of the poor ornamental value, there are many restrictions on the choice of fish. You can only choose some fish that are looking at the back, or just want to feed them. Long-term farming is still possible. In fact, the biggest advantage of canvas fish pond is its low cost. Compared with other fish tanks, canvas fish ponds are still very cost-effective, and the size can be customized according to customer needs. Very practical. If you want to use canvas fish ponds to raise fish for a long time, this scheme can be implemented, but you should pay attention to the selection of fish species.

Canvas fish pond culture technology

1. When building ponds and using canvas ponds to raise fish, you should choose fields close to water sources, open terrain and sunny ventilation to build canvas ponds and disinfect them to avoid harmful substances remaining on the canvas and affecting the growth of fry. And in order to clean the water, you should install a water purification device next to the canvas pool to avoid water pollution.

2. Put the fry in the canvas pond to raise fish, mainly carp and goldfish. Firstly, healthy, lively, harmless and disease-free fry are selected, disinfected with light salt water or diluted disinfectant, and put into the canvas pool. Pay attention to the early breeding density should not be too high, so as to avoid the death of fry.

3. Breeding method Feed fish 2-3 times a day during the breeding period, supplemented by animal feeds such as fish, shrimp, earthworms and animal offal, so that fry can grow better. Pay attention to cleaning up the food residues in the pond after feeding for 2-3 hours every day, so as to avoid the growth of green algae or moss on the canvas wall, which cannot be removed.

Is canvas fish pond suitable for long-term fish farming? 3 canvas fish pond waterproof canvas is based on polyester canvas, and the surface is coated with chemical additives such as PVC paste resin and plasticizer. The waterproof canvas made mainly has the advantages of wear resistance, tear resistance, aging resistance, corrosion resistance, waterproof and air tightness, etc. The galvanized sheet is not easy to oxidize and rust, and it will not be a problem if it is used for six or eight years.

So it fits the word long-term. So what is the effect of raising fish in canvas fish ponds? There are two kinds of fish in canvas fish ponds, one is for breeding and the other is for raising ornamental fish.

Because canvas fish ponds are not as transparent as ordinary fish tanks, they can be viewed in all directions, so they are more suitable for breeding fish such as koi fish and goldfish. This kind of fish has been raised in front of Tengyue Canvas Company in Ganzhou for a long time. Now the somatosensory temperature in Ganzhou has reached 465,438+0℃, and these fish are still well raised and lively, so it is possible to raise ornamental fish in canvas fish ponds for a long time.

It is also the choice of many people to specialize in farming with canvas fish ponds. It is low cost to cultivate in canvas fish ponds. At present, the prices of canvas fish ponds on the market are generally calculated by area, ranging from 9 yuan to 15 yuan per square meter, with an average of13 yuan, 2 yuan, which is quite cost-effective.

Canvas fish ponds are also very convenient for management, feeding and fishing. Compared with traditional soil fish ponds, canvas fish ponds do not need regular dredging. Nowadays, many canvas fish ponds are made of environmentally friendly materials, so you don't have to worry about hurting the cultured fish, and you can cultivate them for a long time. However, the canvas pond is an artificial pond after all, so we should make great efforts to choose the fish suitable for farming when choosing the type of farming.

How to raise fish in canvas pond

1, build a pond

When using canvas pond culture, the canvas pond should be constructed and disinfected in a field close to the water source, with open terrain and sunny ventilation, so as to avoid harmful substances remaining on the canvas and affecting the growth of fry. In addition, in order to clean the water, we should install a water purification device next to the canvas pond to avoid water pollution.

Step 2 put in the fry

The main fish in the canvas pond are carp and goldfish. First, select healthy, lively, harmless and disease-free fry, disinfect them with light salt water or diluted disinfectant, and then put them into the canvas pool. Pay attention to the density not to be too high at the initial stage of breeding to avoid the death of fry.

3. Breeding method

Feed it 2-3 times a day during the breeding period, mainly with special feed for fish, supplemented by animal feed such as fish, shrimp, earthworm and animal viscera, so as to make the fry grow better. Pay attention to cleaning up the food residue in the pond after feeding for 2-3 hours every day to prevent green algae or moss from growing on the canvas wall.
