Description

The accurate combination feeding method of regulating water quality under Polyculture in a kind of aquaculture
Technical field
The present invention relates to a kind of feedstuff feeding method, more particularly, the present invention relates to the accurate combination feeding method of regulating water quality under Polyculture in a kind of aquaculture, belong to technical field of aquaculture.
Background technology
The important developing direction of culture fishery one is " raising together with ", and main Types has: multiple types fish is raised together with, Fish-shrimp mix-culture, fish soft-shelled turtle are raised together with, fish crab is raised together with.But, under Polyculture, new problem is proposed to feed formula, feed production and feedstuff feeding technology.
First be feed formula offering question.In a pond, there are the fish of Different Nutrition demand " are raised together with ", nutritious demand difference is very large fish and shrimp etc. " raising together with ", arrange at dietary nutritional standard and work out with feed formula, for the same pond under " raising together with " pattern, at least need two kinds, even two or more feeds just can satisfy the demand, like this, in same pond, throw something and feed two kinds or two or more feeds is just needed.Under fishes and shrimps, fish crab Polyculture, the particle size of fish feed, Shrimp waste feed, the requirement of water resisting time are widely different, also need to throw something and feed two or more pellets in a pond simultaneously.
At present, the feedstuff feeding under " raising together with " pattern needs feeding method and the technical regulation of formulating " feed set meal ".Namely need in a cultivating pool, throw something and feed two kinds or two or more feeds, it is exactly " feed set meal " feeding method that multiple feed combinations is thrown something and fed simultaneously.
Feed combinations set meal, comprises the combined set meal of same feed variable grain specification feed, and combined set meal two kinds of modes of variety classes feed.Two kinds or two or more feed combinations are thrown something and fed by the combined set meal of variety classes feed in a pond, such as, fish meal, shrimp feed or crab feed are combined, use of throwing something and feeding in same pond.
Two kinds or two or more feeds, in same pond, are thrown something and fed at different time, namely two kinds or two or more feeds are thrown something and fed according to time order and function order by the combined method of feedstuff feeding time.The combined method in feedstuff feeding place, adopts the feedstuff feeding machine of more than two or two, carries out two kinds or two or more feedstuff feedings respectively in different location, this kind of method for fishes and shrimps, that fish crab is raised together with is comparatively suitable.Consequently fish fish meal, Shrimp waste are ingested feed for shrimp and crab, ingest respectively in different places.
Existing feeding technology, mainly under Polyculture, first satisfied master breeds fish, the growth needs of famous and precious fish, and high protein feed of throwing something and feeding in a large number, makes it grow fast, Shortening culturing period, go on the market as early as possible, reaches the object of maximum economic benefit.But under such feeding and management condition, easily ignore the growth needs that other raise together with fish, cause cultivation later stage water body severe exacerbation, reason is: 1, bacillus level of growth when C/N ratio is 15 is best.2, lactic acid bacteria grows best when C/N ratio is 15.3 we be familiar with also being the vibrios of most headache be then C/N ratio be five even lower time growth best.In pond when C/N ratio is more close to ten, bacillus and the inhibition of lactic acid bacteria to vibrios stronger.If we adhere to that original mode of throwing something and feeding is constant, vibrios in water body can be caused to become dominant bacteria, and bacillus and lactobacter growth are suppressed, culture benefit can be reduced on the contrary, increase fish to have an attack of one's old illness risk, cause larger economic loss, cause the serious consequence lost more than gain.
It is CN103348936A that State Intellectual Property Office discloses a publication number in 2013.10.16, name is called the patent of invention of " a kind of cultural method of Squaliobarbus curriculus fingerling ", which disclose a kind of cultural method of Squaliobarbus curriculus fingerling, comprise the steps: that (1) manually sterilizes to fry rearing pond with quicklime, injected clear water after sterilization, and discharge fermentation fertilizer cultivation water quality, throw in Squaliobarbus curriculus fry, cultivate and adopt early stage soya bean slurry or artificial feed to feed Squaliobarbus curriculus fry, cultivate later stage employing artificial feed and feed Squaliobarbus curriculus fry, Squaliobarbus curriculus summer flower is obtained after cultivation, (2) with quicklime, manually sterilized in fry culturing pond, injected clear water after sterilization, and discharge fermentation fertilizer cultivation water quality, throw in Squaliobarbus curriculus summer flower, adopt artificial feed to raise Squaliobarbus curriculus summer flower, after Squaliobarbus curriculus summer flower enters pond, throw in freshwater shrimp seed and raise together with.This inventive method is by reasonably raising together with mode to the control and employing that cultivate fry breeding density, and adopt the artificial feed of high protein to feed, substantially increase disease-resistant rate and the survival rate of Squaliobarbus curriculus fingerling, and effectively raise quality and the survival rate of the fingerling of cultivation.
According to the side effect of existing throw something and feed methods and generation thereof, especially in the middle and later periods of cultivation, as rainy weather, harmful microorganism meeting amount reproduction, a large amount of organic matters such as residual bait, ight soil, biological corpse are decomposed at short notice, deamination, consume a large amount of dissolved oxygens, produce the harmful substances such as a large amount of hydrogen sulphide, ammonia nitrogen, murder by poisoning is caused to cultured fishes, thus fulminant disease causes mortality.
Summary of the invention
The present invention to be intended to solve in prior art feedstuff feeding method under aquaculture Polyculture can make bacillus and lactobacter growth in water body be suppressed, and easily produce harmful substance in water body, cultured fishes are caused to the problem of murder by poisoning, the accurate combination feeding method of regulating water quality under Polyculture in a kind of aquaculture is provided, bacillus and lactic acid bacteria in water body can be made to become dominant bacteria, and prevent the generation of harmful substance.
