Why Canvas Fish Ponds Have Become a New Favorite for Aquaculture? A Comprehensive Analysis of Practical Advantages from a Returning Entrepreneur

Zhang Ming is a young entrepreneur who returned to his hometown to start a fish farming business. During the initial planning phase, he compared various farming methods and ultimately chose canvas fish ponds. The following are practical examples of the advantages of canvas fish ponds based on his own experience:

I. Low Cost and Rapid Deployment: Compared to Concrete Ponds

Zhang Ming initially considered building concrete ponds, but calculations showed that the materials, labor, and waterproofing alone would cost tens of thousands of yuan, and it would take nearly a month after completion before they could be used. Later, he learned about canvas fish ponds and purchased a ready-made set consisting of galvanized steel frames and waterproof canvas for less than half the cost. After delivery, he and his family assembled and installed it in just one day, saving the tedious steps of pouring concrete, waterproofing, and drying. Three days later, he completed water treatment and disinfection and officially introduced the fish fry, significantly shortening the payback period.

II. Flexible and Mobile: Compared to PE Aquaculture Tanks

Zhang Ming's friend, Li Qiang, used PE plastic tanks for aquaculture, but the tanks were heavy and difficult to move, and they developed aging cracks after prolonged exposure to sunlight. Zhang Ming's canvas fish pond uses modular galvanized steel frames, which are flexible to install and easy to disassemble. Last summer, to avoid the effects of high temperatures, he moved the entire fish pond to a shaded area; in winter, he expanded it and covered it with an insulated shed. The galvanized steel frames have a thick zinc layer and have not rusted despite exposure to the elements, while the PE tanks needed replacement after only two years of use, but the canvas pond frames remain as sturdy as new.

III. Clean, Convenient, and Soilless Aquaculture: Compared to Traditional Earthen Ponds

Uncle Wang in the same village operates a traditional earthen pond, which requires time and effort each year for dredging, disinfection, and desalinization, and the water quality is easily affected by mud and sand. Zhang Ming's canvas fish pond is laid directly on a flat surface, with a smooth bottom and no soil impurities. During the farming process, feces and leftover feed can be quickly discharged through the bottom drain valve. After each farming cycle, he only needs to drain, clean, and disinfect the pond, and it can be reused in a few days. Furthermore, the canvas material is non-toxic and harmless, significantly reducing the incidence of fish diseases, and the management efficiency is far superior to that of earthen ponds. Summary:

Through practical experience, Zhang Ming has found that canvas fish ponds offer significant advantages in cost control, construction efficiency, spatial flexibility, and ease of management. They are particularly suitable for small and medium-sized aquaculture farmers with limited funds, potentially changing locations, or those who want to start production quickly. His success has also attracted several neighboring farmers to switch to canvas pond aquaculture, making it a new characteristic model of local aquatic farming.
