Abstract
The invention belongs to the aquaculture technique and relates to a disease-resistant freshwater shrimp culturing method. The disease-resistant freshwater shrimp culturing method comprises the following steps that 1, shrimps are examined, wherein parts of freshwater shrimps are caught, and whether the gills on the two sides of each freshwater shrimp are red or not is examined; 2, detection is conducted according to the pathogenic aeromonas hydrophila inspection procedure; 3, chemical mixing is conducted, wherein povidone iodine is evenly mixed to be dissolved in water; 4, splashing is conducted, wherein chemical liquid obtained through mixing in the step 3 is splashed in a whole pond, and chlorine dioxide particles are thrown into the whole pond; 5, the shrimps are examined, wherein freshwater shrimps are caught again two to three days after the chemical liquid is splashed, whether the freshwater shrimps with the gills on the two sides being red exist or not is checked, and the step 3 and the step 4 are executed repeatedly if yes; 6, detoxication is conducted, wherein water is detoxicated by means of biological organic acid, and thus detoxication of water is reduced; 7, fertilizer is applied into the water, wherein amino acid water fertilizer and biological fertilizer are applied into the water, and the irritability of the freshwater shrimps is reduced by means of VC. According to the disease-resistant freshwater shrimp culturing method, the quality of freshwater shrimp culturing water can be improved, the morbidity and death rate of freshwater shrimps are reduced, and the yield of the freshwater shrimps is increased.
Description
Technical field
The invention belongs to aquaculture technology, relate to the disease-resistant cultural method of a kind of freshwater shrimp.
Background technology
Freshwater shrimp, formal name used at school Japanese macrobrachium supernbum, is under the jurisdiction of Arthropoda, Crustachia, Decapoda, and Palaemonidae, pond crayfish belong to.Shrimp culture has that market prospects are good, technical operation is simple, starting fund is few, production cost is low, economic benefit comparatively advantages of higher, and it is freshwater shrimp fine and tender taste, delicious flavour, nutritious, the dark favor by consumer, market sale is contained for a long time and is not waned, current China shrimp culture annual production more than 20 ten thousand tons.In shrimp culture process, red cheek disease is a kind of common disease, and be the disease that the freshwater shrimp gill caused by infected by Aeromonas hydrophila takes on a red color, its death rate of the onset is generally 30%, and serious lethality of falling ill is up to 70%, and main harm becomes shrimp.Have a strong impact on the output of freshwater shrimp.
Summary of the invention
Technical problem to be solved by this invention is, provides a kind of and can improve shrimp culture water quality, the morbidity of minimizing freshwater shrimp and disease-resistant cultural method that is dead, that improve the freshwater shrimp of freshwater shrimp output.
The disease-resistant cultural method of freshwater shrimp of the present invention comprises the steps:
1) check shrimp body: fish for part freshwater shrimp, check whether freshwater shrimp two pleurobranchiae takes on a red color;
2) pathogenic hydrophila gingivalis inspection procedure is adopted to detect;
3) mixed medicine: povidone iodine is mixed soluble in water, the amount of water, according to pond size, is splashed with just in time enough whole ponds and is advisable for one time;
4) splash: the liquid full pool spilling head mixed in step 3), the full pond of chlorine dioxide particle is shed;
5) check shrimp body: splash medicine after 2 ~ 3 days, fishing freshwater shrimps again, see the freshwater shrimp whether also having two pleurobranchiaes to take on a red color, if any, repeat step 3) and 4);
6) detoxify: adopt biogenic organic acid to detoxify to water body, reduce water body toxicity;
7) rich water: adopt amino acid Fertilizer water paste and bio-fertilizer to carry out rich water to water body, and use VC, reduce freshwater shrimp irritability.
In described step 3), the consumption of povidone iodine is that each meter Shui Shen of every mu of pond uses 250ml, and the consumption of chlorine dioxide is that each meter Shui Shen of every mu of pond uses 300g;
In step 6), the consumption of biogenic organic acid is that each meter Shui Shen of every mu of pond uses 250ml;
In step 7), total consumption of amino acid Fertilizer water paste and bio-fertilizer is that each meter Shui Shen of every mu of pond uses the consumption of 1000g, VC to be that each meter Shui Shen of every mu of pond uses 200g.
In the inventive method, the strong oxidizing property of povidone iodine and chlorine dioxide, has the effect of sterilization and purifying water body; Biogenic organic acid has the effect of removing toxic substances; Amino acid Fertilizer water paste and bio-fertilizer have the effect of rich water; VC has the irritable effect of minimizing.Adopt the acting in conjunction of above biologic product, healthy ecology cultivation freshwater shrimp can be realized, improve the seed output and quality of cultured product.
Embodiment
Below by instantiation further to the detailed description of the invention.
Embodiment 1:
Freshwater shrimp monoculture pond, pond area 4 mu, mean depth of water 1 meter, fishes for part freshwater shrimp, and the pathogenic hydrophila gingivalis inspection procedure adopting the development of animal medicine institute of Agricultural University Of Nanjing to set up checks that shrimp body finds that two pleurobranchiaes take on a red color.1000ml povidone iodine is mixed water full pool spilling head, and the full pond of 1200g chlorine dioxide particle is shed, and after 3 days, prawn body checks, does not find that there is the both sides cheek and takes on a red color.Then use amino acid Fertilizer water paste, biogenic organic acid is 4000g full pool spilling head altogether, and VC1000g is complete, and pond is shed.
Embodiment 2:
Freshwater shrimp monoculture pond, pond area 11 mu, mean depth of water 1.2 meters, fishes for part freshwater shrimp, checks that shrimp body finds that two pleurobranchiaes take on a red color.3500ml povidone iodine is mixed water full pool spilling head, and the full pond of 4000g chlorine dioxide particle is shed, and after 3 days, prawn body checks, does not find that there is the both sides cheek and takes on a red color.Then use amino acid Fertilizer water paste, biogenic organic acid is 14000g full pool spilling head altogether, and VC3500g is complete, and pond is shed.
The breeding process of the embodiment of the present invention effectively reduces the generation of the diseases such as the red cheek disease of freshwater shrimp, improves output.
