Cement or geomembrane is used at the bottom of the fish pond. What fish can be raised in cement ponds?

It is best to use geomembrane at the bottom of fish pond. The so-called geomembrane is a kind of flexible polymer material with relatively small specific gravity, strong ductility, strong adaptability to denaturation, corrosion resistance, low temperature resistance and very environmental protection. If cement is used, although it can be impermeable to water, it is also impermeable to air, and fish can't make holes if they want to, which may even affect the survival of some benthic fish.

Second, what fish can be raised in the cement fish pond 1, goldfish: the cement fish pond is very suitable for raising goldfish. This kind of fish is raised by crucian carp and has a long history in China. Usually divided into four species, namely, grass species, literature species, dragon species and egg species. Cement ponds are suitable for raising grass, flowers and dragons, but it is relatively difficult to raise eggs.

2. koi fish: koi fish and goldfish are both ornamental fish with wide temperance, so it is no problem to keep them in a cement pond. This kind of fish has a variety of feeding habits, mild temperament, likes swimming in groups very much, and is relatively easy to raise. It should be noted that the richness and temperature of bait 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 it is also common to raise it artificially. But because the cement pond can't grow aquatic plants, it should be fed with some plant bait frequently, so that it can grow quickly.
