Description
Technical field
The invention belongs to aquaculture field, relate in particular to a kind of breed waters dissolved oxygen control method and device based on microclimate.
Background technology
Along with popularizing day by day of cage culture in the freshwater aquaculture industry and pond aquaculture model; Cultivation density improves constantly; The Detection & Controling of oxygen in water concentration are extremely important to improving cultured output and quality, and wherein the dissolved oxygen concentration Detection & Controling become the key that improves cultivation density and output.
In the production practices, the water body dissolved oxygen content is too high or too low all to be disadvantageous to aquatic livestock, but that dissolved oxygen content is crossed the low direct or potential harm that aquaculture of aquatic animal is caused is more general.
Generally; 0.5 the LDO water body environment of～2.5mg/L can cause suffocating of general culturing fish and shrimp class and death; Dead speed is then relevant with many factors such as fertile degree of the order of severity of anoxic, water temperature, water: when dissolved oxygen concentration in 2.5～4.0mg/L scope, fish and shrimp possibly can be lived in this low anaerobic condition for a long time, but its metabolic rate slows down; Thereby ingest, aspects such as movable, growth and premunition are not as normal condition, in case and envirment factor sudden change.Ruin like water quality, it is sick then very easily to occur explosive fishes and shrimps during change in weather, thereby breeding production is caused heavy losses.But the water environment state of low anoxic is easy to ignored by the culturist owing to can not cause directly that in a long time " the general pool " reaches dead fish in enormous quantities, extremely the situation of shrimp takes place.
Cause that the not enough reason of oxygen in water mainly contains: 1. temperature is high.Oxygen solubility with temperature in water raises and reduces, and as under an atmospheric pressure, water temperature rises to 35 ℃ by 10 ℃, and the solvability of airborne oxygen in pure water can be reduced to 6.93mg/L by 11.27mg/L, and high temperature can cause that dissolved oxygen reduces.How aquatic livestock also is a major reason with other biology oxygen consumption when high temperature in addition.2. cultivation density is excessive.Biological respiration strengthens, and BOD also increases.3. wind direction and wind velocity changes.The change of wind direction and wind velocity can cause local anoxic.4. organic decomposition.Organic matter is many more, and bacterium is just active more, and this process will consume a large amount of oxygen usually just can carry out, and therefore causes anoxic easily.5. the anoxic that causes of rainfall.
When the water body dissolved oxygen content reached 5.0～7.0mg/L, most of culturing fish and shrimp class can both eubolism, free movable.Simultaneously, keep enough dissolved oxygens in the water, the chemical reaction of the noxious material that can suppress to generate, the content of conversion or reduction noxious material (like ammonia, nitrite and hydrogen sulphide).For example: the organic matter back of rotting produces ammonia and hydrogen sulphide in the water, and having under the condition of sufficient dissolved oxygen, through the decomposition of microorganism, ammonia can be converted into nitrite and change into nitrate, hydrogen sulphide again and then be converted to sulphate, all produces nontoxic end product.
At present, in freshwater aquiculture, water body oxygenation is that generally rule of thumb randomness is bigger; The detection data of existing detecting instrument can't be reacted the state in whole breed waters, and also can't reflect because of wind speed changes the anoxic that causes for the part, some regional anoxic occurs through regular meeting, and some zone is the phenomenon of anoxic not.For shrimp, because scope of activities is little, generally be no more than six meters, very big influence can will be brought to its growth in the zone of anoxic, is taking place when causing the phenomenon of culturing loss owing to oxygenation is untimely.
Summary of the invention

Because dissolved oxygen sensor costs an arm and a leg, a slice is cultured in the waters, only in central authorities a dissolved oxygen sensor is set usually; When wind speed is excessive, because wind meeting oxygenation causes dissolved oxygen sensor testing result distortion (higher) easily; For wind less than the zone, dissolved oxygen content is lower than testing result; Thereby the dissolved oxygen sensor testing result can't reflect the dissolved oxygen concentration situation of whole breed waters scope; And then cause some regional dissolved oxygen concentration low excessively; Influenced the normal growth of aquatic biological, especially for the very little shrimps of moving range, its influence is normally fatal.Through the excessive operating mode of wind speed is further limited, can guarantee to culture dissolved oxygen abundance in the waters, satisfy the normal growth demand of aquatic biological.As preferably, the wind speed threshold value is 2.0～3.0m/s.
As preferably, the inventive method also comprises real-time detection wind direction, and when wind speed surpasses threshold value, and dissolved oxygen content is when being lower than correction value, according to wind direction, to the not good regional oxygenation of circulation of air, reaches correction value to dissolved oxygen content; The not good zone of said circulation of air be meant wind less than or the zone slightly blown over; This oxygenation way, more targeted, can improve oxygenation efficient.
When wind speed during less than the wind speed threshold value, wind speed is very little to the influence of dissolved oxygen content, can ignore.
As preferably, the inventive method comprises that also real-time detection cultures waters temperature and relative moisture, and when temperature surpasses 38 ℃, relative moisture surpasses at 80% o'clock, oxygenation 1～3h; When dissolved oxygen content surpasses correction value, continue oxygenation to the oxygenation time of setting.
The solvability of oxygen in water raises with temperature and reduces, and aquatic biological oxygen consumption when high temperature is many simultaneously, so during hot weather, aquatic biological is anoxic very easily; When humidity is higher in the air, can cause that also oxygen content descends, and causes the aquatic biological anoxic.Through the oxygenation operating mode under high temperature, the super-humid conditions is further limited, " the general pool " phenomenon that can avoid high temperature, high humidity weather to cause is for aquatic livestock is created better growth conditions.
As preferably, the inventive method also comprises real-time detection rainfall, when instantaneous rainfall surpasses 80mm, and oxygenation 1～3h; When dissolved oxygen content surpasses correction value, continue oxygenation up to the oxygenation time of setting.
