Last night, He Fane refreshed his knowledge on the prevention and control of insect diseases. The simplest way is to sprinkle a large amount of pesticides that can kill parasites on his own fishing ground.
But He Fan didn't want to use this method.
?????????????????????????????????????????????????????????????????????????????????????: If these chemicals are thrown in large quantities, they will pollute the water body. Besides, there are not one, but three or four kinds of insect pests in your own fishery!
There are several types of pesticides that need to be sprayed.
When the time comes, if they are thrown into your own fishing ground, it may have a serious impact on the ecological balance of the fishing ground.
Those pesticides are all chemical agents. If they are thrown together, the toxicity may kill the bottom organisms in his own fishery. Then the gain outweighs the loss. This is not the result that He Fan wants to see. .
"You still have to think of another way!"
With this in mind, He Fan also returned to the Storm and said to the boss of the ship:
¡°Let¡¯s return first!¡±
The boss of the ship nodded, turned the Storm around, and began to return.
After returning to the villa area, He Fan was also in a hurry and began to search for more information on the prevention and control of this marine fish disease.
Most of the methods for preventing and controlling this insect disease on the Internet are the same as what He Fan knew before. They mainly focus on spraying insecticides. However, He Fan really found a niche method.
Biological therapy!
The so-called biological therapy relies on some organisms in the ocean that naturally feed on parasites to prevent and treat these parasites that threaten the lives of marine fish.
? Just like the examples of rhinoceros and rhinoceros bird.
Most animals dare not approach the ferocious rhinoceros, but there is a small bird that can rest on the back of a rhinoceros without restraint.
It¡¯s all because this bird can help remove the carrion stuck in the teeth of the rhinoceros, as well as the parasites born on the body.
Therefore, rhinos never harm this small bird, allowing the bird to forage for food in their huge mouths and coexist peacefully. Hence, this bird is called rhinoceros bird!
¡°In the ocean, there is also something that can help fish get rid of parasites.
That¡¯s Cleaning Shrimp!
This kind of shrimp is commonly known as the "bright red lady". Among all aquarium shrimps, it has the highest reputation.
It is all because it is different from ordinary shrimps in appearance. The entire back is bright red, with a white line running through the middle and ending in a T-shape at the tail.
Because of its beautiful appearance and compact size, it can help fish remove parasites and necrotic tissues attached to their bodies, and is easy to maintain in small water bodies such as home tanks. Therefore, it is especially popular among fish keeping enthusiasts. welcome.
Keeping it in a fish tank at home can not only add a beautiful scenery, but also act as a fish tank doctor to prevent domestic fish from getting sick or even dying due to parasites.
How much do these cleaning shrimps love parasites and necrotic tissues? Even if you only extend one hand into the water tank where these cleaning shrimps are kept, these cleaning shrimps will hold up their ingenious tiny "scissors" , start to clean up the dead skin on your hands!
The biological therapy that He Fan found on the Internet proposes to raise these clean shrimps in large quantities in farms.
Let these clean shrimps become the main force in preventing and controlling insect diseases in farms.
However, the only flaw of this biological therapy is that the cost is too high.
?Compared to the direct use of pesticides, the cost is several times, even dozens of times higher.
People set up breeding farms to pursue profits. Therefore, there has never been a market for this kind of biological therapy in the prevention and treatment of insect diseases, and not many people buy it!
After all, this kind of clean shrimp originates from the waters near Indonesia and Sri Lanka. It is imported and very popular. If the market is large, the price will be higher!
Although the cost of this biological therapy is high, He Fan is thinking about it.
This cost is nothing compared to the millions of fish in your own fishery!
And He Fan would definitely not choose the method of putting in insecticides, but he could try this biological therapy.
At the moment, He Fan drove his Wuling Shenqi and set off from the villa area, thinking of going to the seafood pier and asking the seafood vendors about cleaning the shrimps.
but,The result was that He Fan was a little disappointed.
"Little boss, we really don't have these cleaning shrimps here. They are ornamental and have no edible value. Besides, they are not produced in the waters near us. However, we can contact you with some people who can make them. Business colleagues, let them help you take a look!"
Thinking about it, this kind of clean shrimp is more valued by people for its ornamental value. Looking for these seafood vendors yourself is also looking for the wrong way!
At the moment, He Fan asked these seafood vendors to contact them, and he continued to drive to Yangcheng.
The flower and bird market should be a place to buy such ornamental things.
After arriving at the flower and bird market, He Fan went straight to the stalls selling ornamental fish without stopping.
It didn¡¯t take much effort, I just found my goal, cleaning shrimp!
He Fan¡¯s eyes immediately lit up and he asked directly to the stall owner:
"Boss, how do you sell these cleaning shrimps?"
"Hey, the little boss has really good vision. These are authentic red cleaner shrimps imported from Sri Lanka. Buy a pair of these and put them in your home aquarium. It will definitely prevent all the fish in your aquarium from getting sick and greatly reduce losses. Look. It looks good and the price is not expensive. You can take it away in thirty-one pairs!"
The stall owner naturally introduced it to He Fan.
Thirty yuan for two cleaning shrimps, this price is already very expensive compared to other shrimps, and considering the small size of the cleaning shrimps, it highlights its value even more.
However, the added value of this guy is mainly for its ornamental value, but what He Fan values ????is its cleaning function.
At that moment, he said to the stall owner without hesitation:
"I want as many as you have in your store!"
The stall owner was a little confused when He Fan asked him this question.
If He Fan hadn¡¯t even paid back the price, he would have thought it was his colleagues who were causing trouble!
Pointing to a transparent glass jar over there, he said blankly:
"It's all there"
After He Fan took a look, he frowned.
There are only dozens of them in this glass tank, not even a hundred!
The stall owner on the side saw He Fan frowning and thought he had regretted it, so he hurriedly said:
"Little boss, if you sincerely want it, the price can be negotiated. Twenty-five, what do you think?"
Although this cleaning shrimp is popular among fish farming enthusiasts, those who love fish farming are still a minority after all, and they are a niche circle!
