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. 1. Is the canvas fish pond suitable for long-term fish farming? Canvas fish ponds can be kept for a long time if only fish are fed, but there are not many fish species to choose from because of many restrictions. 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.

2. 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.
