Description
Technical field
The present invention relates to aquaculture field, and in particular to a kind of raising Penaeus Vannmei wet weather clear up when stress energy
The method of power.
Background technology
Last century late nineteen eighties, Penaeus Vannmei is introduced into China, and because growth is fast, premunition is deep by foster shrimp person by force
Welcome, be currently the important seawater of China and brackish culture shrimps, cultivation scope popularization is national and is mainly distributed on southern edge
Haiti area, due to its fast growth, feed efficiency is high and economic benefit turns into greatly the main warp of wide farmers increasing both production and income
Ji source, with wide market prospects.
Penaeus Vannmei belongs to Arthropoda, Crustachia.There is no complete immune system, to environmental catastrophe stress reaction
Acutely, it is serious to directly result in death.Continuous overcast and rainy situation about clearing up suddenly is met in breeding process, and to frequently result in South America right in vain
Shrimp large area breaks out disease, and is not easily controlled.
Into it is overcast and rainy when, algae due to intensity of illumination reduction cause respiration be more than photosynthesis, its growth and breeding
Slow down.But the microorganism in water body remain unchanged metabolism it is vigorous.The pH value of water body is gradually reduced in the process.It is any in nature
Growth and breeding of the metabolite of one species to this population are all inhibited.Wet weather persistently gets off due to no algae
Photosynthesis, the Metabolites Concentration of microorganism, which is gradually increasing, can cause micropopulation decline or even occur dead.Due to
Phytoplankton causes " starvation " state by the metabolism based on prolonged respiration, phytoplankton when being cleared up day by wet weather
Violent photosynthesis can be carried out, rapidly consumption water body in inorganic salts and carbon dioxide, and then cause water body pH drastically on
Rise.And microbial growth relatively lags behind water body " fall algae " next can be caused even " to turn water " and then cause the death rate of shrimp to increase
It is high.Lack reply Penaeus Vannmei in the prior art, when continuous wet weather clears up suddenly, the violent death rate of stress reaction is higher
Problem.
The content of the invention
It is an object of the invention to overcome in the prior art above-mentioned technical problem there is provided one kind improve Penaeus Vannmei in the moon
The method of stress ability when rain clears up, methods described can reduce Penaeus Vannmei run into it is overcast and rainy clear up weather when stress
Reaction, improves survival rate.
The purpose of the present invention is achieved by the following technical programs：
A kind of method of stress ability of raising Penaeus Vannmei when wet weather clears up, including following operation：
S1. sterilize
With the disinfection by chlorine dioxide of every mu of 250-300 grams of water body when rainy weather arrives, overcast and rainy every morning period 8-9 point makes
With the disinfection by chlorine dioxide of every mu of 100-150 grams of water body once, every mu of 1000-1500 grams of water splashing quick lime of 20-0 points；
S2. water is changed
Quantity of exchanged water is the 8-10% of member's water below the every mu of water surface 1000 jin of shrimp of carrying, and 1000-2000 jins of quantity of exchanged water are member's water
15-20%, more than 2000 jin quantity of exchanged water are the 25-30% of member's water；
S3. control bacterium-algae balances
After it's clearing up, every mu of 500 grams of water splashing saccharomycete, 1000 grams of brown sugar, daily using once to water body 16-17 points pH
Less than 8.5.
A kind of method of stress ability of raising Penaeus Vannmei when wet weather clears up, including following operation：
S1. sterilize；S2 changes water；S3. control bacterium-algae balances.Once sterilizing is carried out after rainy weather arriving, then per in the sky
Noon 8-8:30 dissolved oxygens and pH value obtain minimum point and carry out once sterilizing, and sterilization can improve water body oxidation-reduction potential and reduce wet weather
The harmful levels of pathogens grown during weather in water body；Shrimp amount is carried according to every mu of water body to carry out changing water, it is ensured that sufficient in water body
Dissolved oxygen amount and water body pH in normal range (NR), exclude water body in harmful levels of pathogens；Splashed during fine day saccharomycete and brown sugar, yeast
Bacterium fermentation produces carbon dioxide, meets the violent photosynthetic demand of planktonic organism after it's clearing up, will not cause in water body
Carbon dioxide content is drastically reduced, and water body pH steeply rises, and " algae " phenomenon occurs.By aforesaid operations, it can carry significantly
The survival rate that high Penaeus Vannmei clears up under weather in wet weather.
Preferably, in the operation S1, the mass percent of the chlorine dioxide is 10%.
Preferably, the operation S2, is that overcast and rainy period 18-23 points are carried out.
Preferably, in the operation S3, the saccharomycete unit mass number of viable is 8.0 × 108cfu/g。
Compared with prior art, the present invention has following technique effect：
A kind of method of stress ability of raising Penaeus Vannmei when wet weather clears up, including following operation：S1. sterilize, it is overcast and rainy
With the disinfection by chlorine dioxide of every mu of 250 grams of water body when weather arrives, overcast and rainy 8 points or so of every morning period uses every mu of water body
100 grams of disinfection by chlorine dioxide once, every mu of 1000 grams of water splashing quick lime when the sun is fallen；S2. water, every mu of water surface are changed
The 8-10% that quantity of exchanged water below 1000 jin of shrimp is member's water is carried, 1000-2000 jins of quantity of exchanged water are the 15-20% of member's water, 2000
Jin above quantity of exchanged water is the 25-30% of member's water；S3. control bacterium-algae balances, after it's clearing up, every mu of water splashing saccharomycete
500 grams, 1000 grams of brown sugar, it is continuous to be less than 8.5 using to water body dusk pH.Once sterilizing is carried out after rainy weather arriving, so
8 points or so of every morning carries out once sterilizing again afterwards, and during sterilization can be with less rainy weather, having for being grown in water body is fallen ill
Bacterium；Shrimp amount is carried according to every mu of water body to carry out changing water, it is ensured that sufficient dissolved oxygen amount and water body pH are in normal model in water body
In enclosing, harmful levels of pathogens in water body is excluded；Splashed during fine day saccharomycete and brown sugar, saccharomycetes to make fermentation produces carbon dioxide, meets day
The violent photosynthetic demand of planktonic organism, will not cause carbon dioxide content in water body drastically to reduce, water body after gas clears up
PH steeply rises, and " algae " phenomenon occurs.By aforesaid operations, Penaeus Vannmei can be greatly improved and cleared up weather in wet weather
Under survival rate.
