[First-line Case] Shrimp Blackened Gill Combination Scheme to Solver Worries
1. Case Details
Time: August 2021
Location: Rhino Foot Town, Qinnan District, Qinzhou City, Guangxi Province
Breeding species: Penaeus vannamei
Farming area: 4 mu of intensive cultivation pond
Water Quality Index: Ph:8.2 Ammonia Nitrogen 1.2 Nitrite 2
Description of the situation (with pictures before treatment): After 93 days of cultivation, 27 prawns were cultured. Farmers were ready to sell prawns. Affected by the typhoon, there was a sudden rainstorm that night. All prawns had black gills one night. The next day, prawns crawled along the edge, stole to death, and food intake slowed down. Prawn black gills will also affect the sale price.
2. treatment scheme
2 mu/bottle of concentrated glutaraldehyde solution in the evening of the first day;
The next evening oxygen bar 2 mu/bottle;
On the evening of the third day, 1 mu/bag +2kg/mu of granular oxygen was eliminated.
3. effect feedback description
After using this scheme, the black gills of prawns improved significantly on the fourth day, the phenomena of climbing and stealing disappeared, and the food for prawns improved significantly.
4. case analysis
The breeding cycle is long, and the bottom of the pond residual bait, feces and dead algae accumulate at the bottom of the pond for a long time. The bottom of the pond is black and smelly in high temperature weather.
Continuous high temperature weather, sudden heavy rain, due to the sudden surface water temperature but the bottom heat, the pond appears reverse bottom resulting in a sharp increase in bacteria in the water, the decline in the physique of prawns resulting in black gills and stealing to death.
Concentrated glutaraldehyde solution, oxygen bar and bacteria for three consecutive days, continue to kill bacteria in water, and long time, less irritating.
5. Product Details
veterinary drug name]
Generic Name: Concentrated Glutaraldehyde Solution (Aquatic)
main ingredient]Glutaraldehyde.
[Sexshape]]This product is a light yellow clear liquid; irritating odor.
role and use]]Disinfection antiseptic. For water disinfection, prevention and control of aquaculture animals by Vibrio, Aeromonas hydrophila, Edwardsiella caused by bacterial diseases.
Usage and dosage]With this product. Dilute 300~500 times with water before use. Sprinkle all over the pool: treatment, once, every 1m3Water body, 0.2g, once every 2~3 days, 2~3 times;
Prevention, every 1m3Water body, 0.2g, every 15 days.
adverse reaction]According to the prescribed usage and dosage, no adverse reactions have been seen.
【Precautions]](1) Do not mix with strong alkali substances.
(2) Use caution when the water is thin.
(3) Pay attention to increasing oxygen after pond use.
(4) Do not use metal containers.
(5) Avoid contact with skin and mucous membranes.
【Hugh Medicine Period] No need to develop
[product name]]oxygen bar
raw material composition]High molecular polymer oxygen.
character]This product is colorless, tasteless liquid.
functional characteristics]
1. This product is high molecular polymer oxygen, which has strong oxygen generating effect. In algae death, water quality mutation, rain weather before and after use, can quickly alleviate the phenomenon of hypoxia.
2. This product can significantly reduce the organic oxygen-consuming substances in the water, the water quality is refreshing, and the continuous increase of ammonia nitrogen and nitrite is controlled.
3, on the water surface oil film, fish body surface dirt has a good cleaning effect; remove shrimp and crab gill dirt, body surface sticky dirty, make it smooth molting.
4. Use in advance when transporting fish or shrimp seedlings to extend the transportation time and increase the survival rate.
[scope of application]]Widely used in fish, shrimp and crabs, crayfish, sea cucumber, jellyfish, shellfish, frogs and other sea and freshwater aquaculture animals.
【Method of use] Sprinkle the whole pool after diluting with water, and concentrate on the floating head of fish and shrimp.

【Precautions] If there is a small amount of precipitation, it can be used as usual without affecting the effect.
[product name] bacteria Lixiao
raw material composition]Sodium persulfate
character]Fuchsia Effervescent Tablets
【Functional features] (1) this product into the water after rapid effervescence dissolution, produce high energy, high activity of small molecular free radicals, reactive oxygen species and other derivatives, significantly improve the water oxidation reduction potential, improve the water and the bottom of the double activity, eliminate water viscosity, purify water quality.
(2) This product can inhibit the growth and reproduction of undesirable algae (cyanobacteria, Euglena, dinoflagellates, etc.) without hurting beneficial algae. Use this product 6~12 hours later, you can use probiotics, long-term improvement of aquaculture water environment.
(3) detoxification and restoration of water ecology, degradation of various types of algae, pesticide residues, chlorine residues, antibiotic residues, degradation of reducing substances affecting water ecology. This product can be used in seedling stage, safe and non-irritating.
(4) regular use, can effectively improve the bottom of the settlement, blackening, fever and other phenomena.
【Scope of application] Applicable to fish, shrimp, crab, jellyfish, sea cucumber, shellfish, crayfish, frogs and other sea and freshwater aquaculture species.
method of use]Outer pond dosage: 2~3 mu/bag.
Indoor dosage: 2m per piece3Water bodies.
In severe cases, the dosage can be increased appropriately.
