　　1、 Construction methods and techniques of anti-seepage film for fish ponds

　　1. Drain the water in the pond, clean the silt and other debris, and then air dry for about 20 days. In winter, air dry the entire season.

　　2. A layer of clay with a thickness of 15-20 centimeters is evenly laid at the bottom and slope of the pond, and mechanically compacted. Then, a layer of anti-seepage film is laid as a protective layer, with a thickness of 0.5 millimeters as the appropriate.

　　3. Measure the scale of the fish pond based on its shape, and then cut and splice the anti-seepage membrane according to the actual situation. The overlap width between the membranes should not be less than 15 centimeters.

　　4. After the completion of the anti-seepage membrane laying, try to avoid walking or moving objects on the membrane surface. Any objects that may damage the anti-seepage membrane cannot be placed on it or carried on the membrane to prevent accidental damage to the membrane surface.

　　5. Spread some grass seeds on the slope to protect it from rainwater erosion.

　　2、 Is it okay to use cement at the bottom of the fish pond

　　1. The bottom of the fish pond can be laid with cement, but this method is not suitable. It is recommended to use geomembrane, which is a polymer flexible material with strong extensibility, small specific gravity, corrosion resistance and low temperature resistance. In addition, it is also relatively environmentally friendly.

　　2. If cement flooring is used, although it can also achieve an impermeable effect, it will result in a bottom that is not breathable, making it difficult for farmed fish to make holes, and even causing adverse effects on the survival of certain benthic fish.

　　3. Cement ponds are suitable for raising carp, goldfish, grass carp and other fish species, but if grass carp are to be raised, it is difficult to plant aquatic plants in the pond. Therefore, it is necessary to feed them with plant-based bait frequently to meet their needs.
