at the bottom of the fish pond. The so-called geomembrane is a kind of polymer flexible material, its specific gravity is relatively small, at the same time has strong extensibility, but also can adapt to denaturation, not only corrosion resistance, low temperature resistance, but also very environmentally friendly. If cement is used, although it can not seep, it is not breathable, and fish can not think of digging holes, and even affect the survival of some benthic fish.
can be raised in cement fish ponds? 1. Goldfish: It is very suitable to raise goldfish in cement fish ponds. This kind of fish is bred from crucian carp, which has a long history in China. It is usually divided into four species, namely, grass species, Wen species, dragon species and egg species. The cement pond is suitable for raising grass seeds, culture seeds and dragon seeds, and the difficulty of raising egg seeds is relatively high.
2. Koi: Koi and goldfish are both eurythermic ornamental fish, so it is no problem to raise them in cement ponds. This kind of fish's feeding habits are more miscellaneous, and its nature is very mild. It likes to swim in groups and is relatively easy to raise. It should be noted that the abundance of bait and the temperature will determine its growth rate.
3. Grass carp: Grass carp is not an ornamental fish, but an edible fish. This kind of fish is distributed in many areas of our country, and artificial breeding is also very common, but because the cement pond can not grow aquatic plants, it is often fed with some plant bait, so that it can grow rapidly.
