Improving the survival rate of fish fry has become the key to improving the efficiency of ponds, and reasonable disinfection prevention planning is an important means to ensure the survival rate of fish fry.
As soon as the price of fish recovers, it is difficult to replenish the seedlings, and the survival rate is the benefit
Compared with last year, the recent pond storage in the two lakes area has shown a significant downward trend, and the current pond storage is only about 20%.
At the same time, due to the sharp decline in seedlings in 2023, the current market of 1-3 seedlings has reached 7 yuan/kg in some areas.
From the perspective of seedlings, the survival rate will directly affect our breeding output and efficiency, and the seedling protection action is imminent!
Second, the incidence of diseases is high, and prevention is greater than cure
The continuous low temperature and rainy weather from mid-March to late April, although the market incidence is not serious, but it leads to the delay in the early feeding rhythm and weak physique; at the same time, as the temperature rises and the weather clears, the pathogenic bacteria will explode in the ponds that have been flooded due to long-term heavy rain.
This year, the price of seedlings is high and difficult to replenish, and it is the top priority to keep the existing seedlings in the pond and improve the survival rate!
According to the three-ring theory of fish health, the environment, physique, and pathogens all need to be regulated and operated by reasonable management means, and after continuous rain and sunshine, we need to control the number of pathogenic bacteria, that is, the disinfection operation of the pond, and a reasonable disinfection plan can effectively control our pond pathogenic bacteria, reduce the incidence, reduce the loss, and ensure the benefits!
Third, disinfection prevention is planned, and seedling protection is smoother
01How to tell if the disinfection product has played a role?
Dichloroeffervescent tablets are the main ones in our commonly used disinfection products, and in order to ensure the best results, we need to pay close attention to their performance from the following key aspects.
Please pay close attention
(1) Whether the effective content is true: many manufacturers falsely label the content, and the actual effective chlorine content is too low, which is difficult to achieve the sterilization effect, resulting in prevention failure and pond disease.
(2) Whether the sanitizing effect is long-lasting: whether the inhibition time of the pathogen can reach the expected level is related to whether the subsequent treatment/supplementation (antibacterial) operation is valuable.
(3) Effervescent dissolution time: whether it can be dissolved within 1 minute to reach the local sterilization concentration; if the dissolution is too slow and the concentration is not up to standard, there is no sterilization effect.
02 New disinfection option - Hailianke bacteria quick cleaning
Based on the above needs, Hailianke's core disinfection product, Bacteria Quick Clearing, can provide you with a more matching solution.
Bacterium quick clear features
(1) The effective content is real, the 8% content is not false, the effervescent dissolution time is fast, and the pond disinfection and sterilization concentration is met.
(2) The disinfection effect lasts for 16 hours, the pathogen rebounds slowly, and there is plenty of time for internal administration/supplementation of beneficial bacteria, which can better prevent and stop loss operations.
03How to use disinfection products?
Do you know when to use disinfection products, how much, and where?
Specific usage scenarios
(1) Long-term rain turns sunny: long-term rain, resulting in serious pond flooding, insect eggs, pathogenic bacteria into the water body, after the sunshine and temperature multiplication, this is the best period for sterilization and antibacterial, should be disinfected in the whole pool.
(2) Cooperate with treatment: In the case of fish disease has occurred, it is also necessary to combine environmental disinfection in the case of internal admixture, so as to control the pathogenic bacteria in the environment and fish body to achieve the therapeutic effect, and disinfection should be carried out before and after the internal treatment cycle.
(3) After insecticide: After insecticide, the number of insects and algae in the pond decreases significantly, and the breeding space of pathogenic bacteria expands, so it is necessary to carry out disinfection and sterilization operations, and the whole pond is disinfected at this time.
(4) Regular food table: The food table belongs to the accumulation of a large amount of residual erbium feces, which is most likely to breed pathogenic bacteria, and if you want to effectively reduce the probability of disease in the pond, it is recommended to carry out regular disinfection in the food field for 7-10 days / times after returning to warm.
Note: Bacterial quick cleaning can provide stable disinfection and antibacterial effect within 24 hours, and the harmful bacteria killing can achieve a more ideal effect.
