With the passage of time, the aquaculture industry with a long history in my country is constantly innovating and becoming more adaptable and more in line with the requirements of social development. Nowadays, our country implements returning farmland to forests, and agricultural land can no longer be used for arbitrary transformation and breeding. In order to increase the utilization rate of resources, an artificial pool that can also be used to breed aquatic products in the mountains has gradually been developed-galvanized canvas fish pond.

This model has few restrictions on conditions. As long as there is water, it can be raised. It can also be raised at a high density, which is several times higher than pond farming. If the circulating water system is well managed and the management is in place, canvas fish pond farming can also be well cultivated, so canvas fish ponds have also become a popular aquaculture equipment in the past two years.

One acre of land is about 666 square meters. Take an ordinary galvanized sheet round canvas fish pond with a diameter of ten meters and a height of 1.45 meters as an example. The area of ​​a ten-meter diameter fish pond is about 3.14*5²=78.5M². Together with the installation base of the pond, a pond occupies an area of ​​about 95M². So one acre of land can place up to seven canvas ponds. The price of a set of galvanized sheet canvas fish ponds with a diameter of ten meters and a height of one meter and four or five is about four thousand yuan, and seven ponds are only more than thirty thousand yuan.

High-density breeding in canvas fish ponds can breed about 20 to 60 kilograms of fish per cubic meter of water. It depends on the experience of the breeders and the species of fish to be farmed. Calculated based on the breeding of 20 kilograms of fish per cubic meter of water, a fish pond with a diameter of ten meters can breed about two thousand kilograms, and one acre of land can breed tens of thousands of kilograms, with very considerable benefits and efficiency.
