[0002] The stream grouper is a kind of freshwater grouper, but this fish is a special species that only belongs to the stream. It only stays in clean waters and has very high requirements for water quality. This grouper is also called the smooth-lipped fish. It grows in the cracks of rocks in the ditches and streams in the southern mountainous areas, or at the bottom of deep pools. The fish's body is gray-black with obvious black patterns. There is a whisker on each side of the corner of its mouth. The adult fish is about 12 to 15 cm long and weighs about 50 grams. The largest is 150 grams. It feeds on stoneworms, small aquatic animals and microorganisms in the stream. It has a beautiful appearance, a strong physique, and strong disease resistance. It is liked Jumping; in the breeding process, the water source requires unpolluted stream water, which is introduced into the pond through channels, entering from one end of the pond and exiting from the other end. Flowing water breeding is mainly used. When feeding, small amounts of feed are usually fed multiple times to reduce the chance of the feed sinking to the bottom of the pond. However, the water in the pond is flowing, so some of the feed will flow along with the water flow to the external environment, and some of the feed that sinks to the bottom of the pond will also increase the nitrogen and phosphorus content of the flowing water, making the water in the external environment prone to eutrophication due to the untreated tail water flowing out of the pond, thereby causing pollution to the external water environment.
