technical field

The invention relates to a loach ecological circulation flowing water culture system, which belongs to the field of aquaculture facilities.

Background technique

Loach, Fish class, Cyprinidae, Cyprinidae, Loach family, Loach genus, also known as loach. Loach is called "the ginseng in the water", and it is distributed in various places in southern China, but it is not common in the north, but it is also distributed in various places. It can be harvested throughout the year, most in summer. After the loach is caught, it can be used fresh or dried. Loaches live in lakes and ponds, and are the smallest in size, only three or four inches long.

Loach is widely distributed in China, Japan, Korea, Russia and India along the coast of Asia, and is edible and used as medicine. Loach is also rich in nucleosides, which are the main components of various vaccines and can improve the body's ability to resist viruses. Phosphoglucomutase has a good adjuvant therapeutic effect on hepatitis and cancer. Loach fish contains high-quality protein, fat, vitamin A, vitamin B1, niacin, iron, phosphorus, calcium and so on. It is sweet in taste and flat in nature, and has the effects of nourishing the middle and replenishing qi, nourishing the kidney and generating essence. It has a better effect on regulating sexual function. Adult men often eat loach to nourish and strengthen their bodies. Sweet in taste and flat in nature, it has the effects of warming the middle and nourishing qi, clearing urine, detoxifying and closing hemorrhoids. Loach has tender meat and high nutritional value, and its slippery saliva has antibacterial and anti-inflammatory effects. It can cure damp-heat jaundice, dysuria, and night sweats after illness.

Traditional loach pond culture methods mostly use pond bottom silt or laying soft soil as the habitat of loach. The organic matter and harmful substances in the pond bottom and water body are too high. The accumulation of fish excrement and the high oxygen consumption of the water body make it difficult to maintain good dissolved oxygen conditions and water quality indicators, which not only seriously restricts the life and growth of loaches, but also the bait that sinks into the bottom mud is not easy to be eaten and utilized by loaches, resulting in waste of bait , especially the loach that inhabits in the mud has a strong fishy smell and poor quality.

Loach is an export-oriented aquatic product that is in short supply in the domestic and international markets. Its quality, specification and quality are the most important factors affecting the price. The current intensive farming method in the aquaculture industry is mainly characterized by a large amount of bait input. On the one hand, the residual bait and fish excrement in the pond seriously pollute the aquaculture environment, the biological and chemical oxygen consumption of the water body increases, and a large number of toxic and harmful substances breed. Diseases of breeding objects occur frequently, and continuous and large amounts of drugs are used to control them, resulting in the residue of toxic and harmful substances in aquatic products, which seriously endangers the health of consumers; sustainable development of aquaculture. Therefore, through healthy breeding and ecological breeding, controlling toxic and harmful substances in the breeding process, improving the quality of aquatic products, and producing pollution-free aquatic products and green aquatic products have become the key points for realizing the optimization of the industrial structure, transformation and upgrading and sustainable development of the aquaculture industry. direction.
