The first is that the bait fertilizer has a high coefficient, the cost of water and electricity is high, and the breeding cost is higher by more than 20%.
The second is the slow growth of fish, fish disease, and high mortality.
The third is to reduce economic efficiency by 30%.
To prevent the leakage of fish ponds can take the following four methods:
1. Plastic film impermeable. Measure the bottom of the pool with the agricultural film and the pool bowl. At the joint, two farm films are pressed and stacked 35 centimeters. Then cover 20 centimeters thick soil. A guide trough should be built to draw water into the pool during irrigation so as not to flush the dirt and damage the plastic film.
2. Shop clay or loam soil impermeable. Suitable for the transformation of sandy loam and loam soil ponds. Dig up the original pond bottom and the pool with more humus-containing soil, spread 40 cm thick clay or loam on the new soil layer, use mechanical tamping or compaction, and immediately release water after treatment to prevent dry cracking and water leakage.
3. Paving soot and seepage. Suitable for the transformation of sandy loam and loam soil ponds. Dig a layer of soil from the original pool bottom and the pool floor. On the new soil layer, 20 cm thick ash soil is made. The lime soil is made of 3 lime powders, 7 loam soils, and it is mechanically rolled or compacted.
4. With water hanging silt impermeable. Suitable for ponds that have been filled with water and fish. Use a woven bag or a dense mesh bag filled with loamy soil or clay, tie one end with a rope, let the bag draw at the bottom, and repeatedly pull in the fish pond, including the bottom of the pool and the pool bowl. When the bag feels light, you should add clay again. Fish ponds that have already put fish should first pull one-half of the pool and then pull the other half.
