Chapter 247 Mysterious Feed "Domestic Fish Fry Breeding Base? There is not much difference between countries in the ground facilities, the breeding environment of wild fish is even worse, and no matter how artificially constructed, the fry can avoid natural predators, and the feed can also prevent the fry from starving. We are not bad at road facilities, that is, the food in the early stage of the fry, we are more than one grade worse than the old beauty. ”

Zhang Canhui is tall and thin, very handsome, and he can see that he was also a handsome guy twenty years ago.

But his right hand is a little inflexible, maybe he has been injured, everyone has eaten together, he uses his left hand to hold chopsticks.

He pays more attention to diet and maintenance than the average person.

Tang Hai is not taboo in meat and vegetables, what to eat, but Tang Hai likes to eat sea fish more often, this is Messi's recipe when he was under Gua Shuai, at that time Messi was forced to eat only fish, especially salmon, during the period of his technical growth, his physical fitness was also growing. This is a terrible person, and he has also lost weight this year and has become what people call the 'strongest Messi'. Tang Hai himself is also a nutrition expert, and he basically demands himself according to the requirements of athletes.

Zhang Canhui is different, his way of eating is to maintain longevity.

The last time he ate, he ate two bowls of vegetables in a small bowl with a big fist, and then he started to eat meat and rice, Tang Hai even noticed that he chewed very carefully, so that he would eat a body that was no less than that of a young man when he was fifty years old.

The hair is very thin, indicating that he has insufficient protein intake, which is protecting the kidneys, and the competition between middle and old age is actually the ability of the kidneys and the heart!

"The reason why our four major domestic fish have successfully multiplied in large quantities is that in addition to Mr. Zhong Fanlin's technology, it is juvenile feed."

"Juvenile feed?"

"Feed is the most critical point of breeding, local chickens eat insect eggs on oil, Japan's bluefin tuna also depends on eating good fish to taste good, the four big fish juveniles have poor digestion, so in the initial time to feed them with digested feed."

That is, poop......

The cleanest digested poop of pigs, cows and sheep is the cow's, and the worst is the sheep's, and the reason why these things have maggots under flies is because maggots are not very digestive, and the fine organic matter that has been ground but not digested happens to be their food.

This is the biggest secret to the high survival rate of juvenile fish!

However, the digestion ability of the four major fish is different, so the type of poop selected at the beginning of the hatchery tank of different fish is also different.

"Fuyuan's salmon juveniles, also use this?"

Zhang Canhui smiled: "Of course not, but that's the core secret, I won't tell it." ”

Tang Hai also smiled, the reason why Zhang Canhui stayed here was that he also wanted to learn Lao Mei's techniques and exchange some salmon techniques from Fuyuan. As for the core content, both sides will definitely have reservations. Because Tang Hai is an American citizen, no, even if he is a Chinese national, it is impossible for Zhang Canhui to say the core technology.

"I provided Lao Mei with several feeds that I had tried, all of which were cheap feeds that could increase the survival rate, and the results were ......"

"They refused?"

"Yes, they have better and more expensive ones! Most of us are still researching how to use plants as feed, and they basically use fish as feed here! Either a species of marine fish from Peru or a native carp! This is the advantage of fewer people! This time it was even more excessive, and I actually fed the fish with a feed made of jellyfish! Are they running out of jellyfish? ”

Tang Hai looked at the sky leisurely, there are too many foods to choose from here, jellyfish like to try it now, or girls who are losing weight love to eat it...... However, it is true that there is often a surplus of agricultural products here......

"That feed is really overbearing, I've been watching it for a week, and the fry are basically not dead! And the fry grow fast! It's horrible! If you can bring that thing back to China and use it to raise Treasure Fish, the survival rate of the juvenile Treasure Fish is only 5%! If it is used to breed Chinese sturgeons, what a use! ”

"Is it a prohibited export?"

"No, it's a very low yield, and now it doesn't matter if you can't buy a single bag! I don't know what cherished jellyfish to do, a company called Flying Fish Feed Factory produced! ”

Tang Hai's expression suddenly became very exciting......

"Mr. Tang, what's wrong with you?"

"That, the materials for making that batch of feed, should have been provided by me to the Flying Fish Company."

This time it was Zhang Canhui's turn to be stunned......

Tang Hai found Hadley, and Zhang Canhui was still in a daze by the hatching pool.

Hadley is tinkering with the feed, and the most important thing in juvenile feed is the atomization ability. Tang Hai left before, and he hadn't figured out how this hatching pool was doing, so he just asked at this time.

Talking about these sockeye salmon, Hadley was emotional, gushing in Chinese to explain this Sino-US joint technology.

Salmon could not be raised in China before, more than 10 years ago, when it came to salmon, salmon, salmon, everyone felt that it was high-end and high-grade, until 2002......

In 2002, China's Pacific Industrial Group finally completed the technical research and developed a complete set of colorful salmon breeding technology, so that the survival rate of artificial hatching reached 70%, until it can be produced, and the disease rate can be controlled within 3%!

This technology was selected into the 'Spark Project' in 2003, and now, it can be said to be impeccable!

Tang Hai saw live water entering the pool before, and it turned out that it was only a part!

In addition, there is a part of mountain spring water and groundwater intake, which comes in from the buried pipe, and Tang Hai can't see it!

In addition, most of the feed used in salmon farming is made from deep-sea organisms, which is the secret of various countries!

The United States obtained the colorful salmon technology of the Spark program in exchange for freshwater sterilization technology.

Speaking of egg pain, this technology was originally researched to kill carp, but later found that it did not work, Florida alone is known as 8000 lakes, Washington State is known as a dense water network, think about the United States and China's land base and the total amount of various resources, who can poison the waters of the country? Besides, who can control the killing of only Asian carps? European carp recipes, like resistance, have to die! Do you still eat bronze snapper? And then there's the American carp and the like.

As a result, not long after the experiment was conducted, it was withdrawn and instead of researching targeted sterilization technology to save the salmon. Originally, the purpose of killing carp was to save the salmon, but although it turned a corner, the purpose remained the same, so the research continued.

"This is feed? Can I try feeding the fish? "Tang Hai's hands itch as soon as he sees the feed.

"Yes, but these two should be mixed to feed, one is the nutritional feed of the flying fish company, the nutrition is great, the atomization effect is very strong, and the other is the antibacterial and disease-resistant feed, and it will be fed for another week until the young fish grow up and improve their disease resistance."
