Description
Technical field
The present invention relates to a kind of loach ecological circulation flowing water culture system, belong to aquaculture installation field.
Background technology
Loach, net-rope, Cypriniformes, Cyprinoidei, Cobitidae, loach belong to, and also claim loach fish.Loach is called as " ginseng in water ", all has the distribution north uncommon but the various places that also distribute in southern china various places.The whole year all can gather, and summer is maximum, after loach catches, and can using fresh herb or oven dry use.Loach lives in Hu Chi, and body is minimum, only has three, four cun long.
Loach is distributed widely in China of Asia bank, Japan, Korea, the ground such as Russia and India, edible, is used as medicine.Also containing abundant nucleosides in loach body, nucleosides is the Main Ingredients and Appearance of various vaccine, can improve health anti-virus ability.Phosphoglucomutase has good auxiliary therapeutic action to hepatitis, cancer.Loach fish is containing good protein, fat, vitamin A, vitamin B1, nicotinic acid, iron, phosphorus, calcium etc.Its taste is sweet, and property is put down, and has tonifying middle-Jiao and Qi, supports kidney production of sperm effect.Good effect is had to adjusting sexual function.Man often eats loach can nourishing and fit keeping function.The sweet property of taste is put down, and has effect of beneficial gas in warming up, clear diuresis, removing toxic substances receipts hemorrhoid.Loach fine and tender taste, nutritive value is very high, and its sliding saliva has the effect of anti-inflammation.The disease such as jaundice with damp-heat pathogen, difficult urination, after being ill night sweat can be controlled.
Traditional loach pond culture mode, large mainly with mud at the bottom of pond or lay the habitat of soft earth as loach, organic and harmful substance contents is too high at the bottom of pond and in water body, and along with the increase of loach daily ration, feeding quantity, the residual bait in pond and the excremental accumulation of fish body, water body oxygen demand is large, be difficult to maintain good dissolved oxygen condition and water quality index, not only seriously govern the life growth of loach, and sink to bait in bed mud and not easily to be ingested utilization by loach, bait is caused to waste, the loach mud fishy smell of particularly perching in mud is dense, inferior quality.
Loach belongs to export-oriented industry aquatic products, and supply falls short of demand in international market at home, and its quality, specification quality are the main factors affecting price.The intensive culture mode for main feature is dropped into a large amount of bait in current culture fishery, on the one hand, the residual bait in pond and fish body excreta severe contamination breeding environment, aqueous bio, chemical oxygen consumption (COC) are aggravated, poisonous and harmful substance is grown in a large number, and cultivation object disease takes place frequently, and controls with lasting, a large amount of medicine, cause the residual of aquatic products poisonous and harmful substances, the health of serious harm consumer; On the other hand, the discharge of a large amount of breeding wastewaters also brings environmental pollution, seriously governs the sustainable development of culture fishery.Therefore, by healthy aquaculture, ecologic breeding mode, in breeding process, control poisonous and harmful substance, promote aquatic product quality, produce nuisanceless aquatic products, green aquatic product, become the direction realizing culture fishery industrial structure optimization, transition and upgrade and sustainable development.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of loach ecological circulation flowing water culture system, to overcome in traditional loach breeding mode using mud at the bottom of pond or lay the habitat of soft earth as loach, to cause at the bottom of pond and organic and harmful substance contents is too high in water body, and make the residual bait in pond and the accumulation of fish body excreta along with the increase of loach daily ration, feeding quantity, water body oxygen demand is large, be difficult to maintain good dissolved oxygen condition and water quality index, the growth that seriously govern loach causes loach mud fishy smell dense, the defect of inferior quality.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of loach ecological circulation flowing water culture system, comprises rectangle loach breeding pond, drain ditch, water vermiculture ditch, wetland purification canal and water purification and collects canal,
