One, climbing perch Guizhou Province Qiandongnan can be cultured

Two, the growing environment

1, turtle shell climbing perch is climbing perch family of small fish, is a perennial, group or solitary, diurnal, omnivorous partial carnivorous native freshwater fishes, adult and juvenile fish are near the water surface of the free-swimming animals, the main intake of small aquatic animals, including earthworms, insects, small fish, as well as duckweed and some fresh water plants. It mainly feeds on small aquatic animals including earthworms, insects, small fish, floating weeds and some fresh water plants. Inhabiting in the still, slow water, silt more water bodies.

2, when the living environment is polluted, water quality deterioration and odor, other fish can not survive the successive deaths, this small fish is still tenacious, but it does not like to live in the polluted water, whenever heavy rain, the water level rises, the fish will collectively climb ashore, to find a good new environment to live. Often rely on swinging gill covers, pectoral fins, turning over and other methods to climb over the embankments, slopes, moving to new waters, or lurking in the silt.

3, the turtle shell perch gill epiglottis is very developed, can breathe air, so away from the water for a longer period of time without dying, when the water body lack of oxygen, away from the water, or in a slightly moist soil can live for a longer period of time. Turtle shell perch have a certain degree of tolerance to salt and fresh water, so it can be widely distributed in the lowlands and near the estuary of the Kee Wai and other swamps, in South China region by the heavy rains ringing with flooding, the lower reaches of the Pearl River turtle shell perch can be washed to the western part of Hong Kong Lantau Island North and the area of the Lau Fau Shan in the flood, in the very light sea surface to swim to the coast of the various sizes of the rivers and streams, and so on and so forth, it is the Hong Kong a few can be from the mainland to constantly replenish the individual secondary diffusion of the form of the It is one of the few freshwater fishes in Hong Kong that can continuously replenish individuals by secondary dispersal from the mainland. It is one of the few freshwater fishes in Hong Kong that can continuously replenish individuals by secondary dispersal from the mainland. In the composition of fishes in Hong Kong, it belongs to the middle to surface fishes in the shallow waters of the downstream lowlands and swampy areas, and is a staple feeder of small animals. They are not very sensitive to pollution, but the number of survivors can reflect serious water pollution and serve as indicator species.
