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

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

Canvas fish ponds can be kept for a long time if they are only for feeding fish, but there are not many fish species to choose from because of its many restrictions. Usually, only some fish can be kept, and it is not easy to install other equipment and change water. Its biggest advantage is that the cost is relatively low. There are at least dozens of fish tanks, and even thousands of good ones, while the canvas fish pond is only about 10 yuan per square meter.

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

1, Difficult to take care of: The primary problem of canvas fish pond is that it is difficult to take care of. Unlike ordinary fish tanks, it is difficult to install filters and other equipment, so the water quality is very problematic, and it is often necessary to change the water. Moreover, if green algae grow, it is not easy to clean and it is difficult to control the water temperature.

2, poor ornamental: ordinary glass fish tanks are transparent, and you can see the fish's activities from all directions, but canvas fish ponds can't. Generally, you can only look from top to bottom. In this case, viewing is limited, and you don't know the fish's situation well, and you may even miss the opportunity to treat the disease.

3. Fish species restriction: As mentioned above, the canvas fish pond can only be viewed from the top, so the fish raised must also be viewed from the back, such as goldfish and koi fish. Of course, if this fish pond is used, some edible fish can also be raised, such as perch and Pelteobagrus fulvidraco.

Is the canvas fish pond suitable for long-term fish culture? 2 The raw material of the canvas fish pond is PVC plastic-coated cloth, which is waterproof, wear-resistant and sun-resistant. Just looking at this reservoir, the service life is still relatively long, which seems to be consistent with the word long-term. Then, let's take a look at the choice of fish. Are all the fish suitable for long-term breeding in the canvas fish pond? The answer is definitelyno. Different fish have different requirements for the growth environment.

The most important thing is the water quality problem that can't be ignored. Canvas fish ponds are different from other fish tanks in the open air mode, and it is difficult to control the water temperature. Besides, canvas fish ponds are not transparent, and the ornamental value may not be so good compared with ordinary fish tanks. If there are some problems with the fish, 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 watching the back, or just want to feed these fish. Long-term farming is still possible. In fact, the biggest advantage of the canvas fish pond is its low cost. Compared with other fish tanks, the canvas fish pond is still very cost-effective, and its size can be customized according to customer needs. It is very practical. If you want to use the canvas fish pond to raise fish for a long time, this plan can be implemented, but you should pay attention to the selection of fish species.

Cultivation techniques of canvas fish pond

1 When building a pond and using a canvas pond to raise fish, you should choose a field close to the water source, with open terrain and sunny ventilation to build the canvas pond, and disinfect it to avoid harmful substances remaining on the canvas and affecting the growth of fry. Moreover, for the sake of clean water quality, you should install a water purification device next to the canvas pond to avoid water pollution.

2. Put the fry in the canvas pool to raise fish, mainly carp and goldfish. First, select the fry that are strong, lively, harmless and disease-free, disinfect them with light salt water or diluted disinfectant, and put them in the canvas pool. Pay attention to the fact that the density should not be too high at the initial stage of breeding to avoid fry death.

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

Is the canvas fish pond suitable for long-term fish farming? 3 The waterproof canvas of the canvas fish pond 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 and tear resistance, aging resistance, corrosion resistance, water resistance and air tightness, and galvanized sheet is not easy to oxidize and rust, so it is not a problem to use it for six or eight years.

So it is very consistent with the word long-term. So what's 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 the canvas fish pond is not as transparent as a general fish tank, and can be viewed in all directions, it is more suitable for breeding fish such as koi fish and goldfish. This type of fish was raised at the entrance of Tengyue Canvas Company in Ganzhou for a long time, and now the somatosensory temperature in Ganzhou has reached 4 1℃, and these fish are still well raised and lively, so it is possible to raise ornamental fish with canvas fish pond for a long time.

It is also the choice of many people to specialize in farming with canvas fish ponds. The cost of farming with canvas fish ponds is low. At present, the price of canvas fish ponds in the market is generally calculated according to the area. One square meter is about 9 to 15 yuan, and on average, it is 12 or 3 yuan. The price-performance ratio is good.

Canvas fish ponds are also very convenient to manage, feed and fish. Compared with traditional earthen ponds, canvas fish ponds do not need to be dredged regularly. Now many canvas fish ponds are made of environmentally friendly materials, and there is no need to worry about harming farmed fish, so they can be used for long-term farming. However, the canvas pond is an artificial pond after all, so we should make great efforts to select the fish suitable for farming when choosing the types of farming.

How to raise fish in canvas pond

1, build a pond

When using canvas ponds to raise fish, we should choose fields close to the water source, with open terrain and sunny ventilation to build canvas ponds and disinfect them, so as to avoid harmful substances remaining on the canvas and affecting the growth of fry. Moreover, in order to clean the water, we should install water purification devices next to the canvas ponds to avoid water pollution.

2. Put in fry

Carp and goldfish are the main fish in canvas pond. First, fry with strong body, liveliness, no damage and no disease are selected, disinfected with light salt water or diluted disinfectant, and then put into canvas pond. Pay attention to that the density should not be too high at the initial stage of breeding to avoid fry death.

3. Breeding method

Feed 2-3 times a day during the breeding period, mainly fish-specific feed, supplemented by animal feeds such as fish, shrimp, earthworms and animal viscera, so that fry can grow better. Pay attention to cleaning up food residues in the pond after feeding for 2-3 hours a day to prevent green algae or moss from growing on the canvas wall.
