"Is your goal to become Tarzan of the Apes?" After a while, Jennifer asked hesitantly.

Tang Hai glanced at it, and returned Tarzan of the Apes, weak or not!

"My goal is to make Xiao Ming a beast!"

The beast makes this nickname fierce, but anyone who has seen the nickname 'Forever Ten Year Old Boy' knows that the beast makes Xiao Ming a pangolin, a few mice, and a butterfly.

If you think about it carefully, the name is majestic, and the strength is 108,000 miles worse than Mount Tai!

However, the three people present were obviously not affected by the divine manga that could not be ended, and as soon as they heard the three words of the beast, they felt tall, and their eyes when they looked at Tang Hai became surprised.

"By the way, three, I've heard of an aquaculture technique where you build a pond and then inject seawater, and then inject ordinary river water to dilute it, and slowly turn some of the marine shrimp into freshwater shrimp, which is easier to manage...... When it's time to sell it, the fresh water is slowly turned into seawater, so that the taste of the shrimp can be restored. ”

Tang Hai is talking about a kind of breeding technology that has existed several years ago, and he only remembers that there is freshwater and freshwater seafood, and the specific steps are not clear.

"You ask this......" Hadley knew about it, but his expression was visibly gloomy when he explained.

It turns out that there is no clear boundary between seafood and seafood.

In the case of fish, fish are animals themselves, so they have salt in their bodies.

If something with salt is soaked in fresh water, according to the principle of osmotic pressure, the body of the fish will absorb water, and the freshwater fish must have a strong ability to remove water from the body.

Marine organisms also have salt in their bodies, but the salt content is lower than that of seawater, so that seawater will absorb water from their bodies, and they must drink a lot of seawater to keep them hydrated, but they have to excrete the excess salt.

Each aquatic organism has a strong ability to drain water and salt, and the main organs are the gills and liver, etc., according to different abilities, they are divided into freshwater fish and marine fish.

For example, shrimp have better muscle mass, are protected by their shells, are less affected by salt than fish, and have a stronger internal organ capacity than shrimp compared to their small bodies.

For example, shrimp is equivalent to loading the power system of a motorcycle onto a bicycle. And some fish are equivalent to loading the power system of a car on a train.

In this way, changing the farming method makes it easier for shrimp to adapt.

This kind of organisms that can easily grow in various salty waters are called macrohaline organisms.

The same is true for some migratory organisms.

Non-broad-haline organisms may also be able to change their habits after dozens of generations under human control.

"This is the study of species modification, which is contrary to the laws of nature and is likely to cause a racial catastrophe. And we're not going to do that either. Jordan looked at Tang Hai vigilantly.

"Even if it's just for the convenience of breeding, only one generation of transformation...... Truth be told, unless there are a few experts in this area who are watching in shifts, it is also easy to have problems. ”

"You, why, why do you suddenly want to ask, this question?"

The three of them who were talking and laughing just now were suddenly full of vigilance against Tang Hai.

……

The scientific and technological progress of human beings has extended to the 'forbidden zone of God', and has the ability to transform species.

In terms of plants, the United States has been eating genetically modified foods for 30 years, and some people who insist on eating non-GMO foods must buy books such as the "Guide to Non-GMO Foods" to know what foods have not been genetically modified.

The biggest advantage of genetically modified is that it can control yield, cold tolerance, drought tolerance, etc., even if all the world's crops are used for human consumption, it can only supply 13 billion people, so genetically modified appeared. In places like Africa, where there is no rain a year, drought-tolerant genetically modified corn and soybeans have saved many people.

But genetically modified plants are not harmless.

Like a certain celebrity ** alarmist, saying that Chinese eat genetically modified organisms and die 700 million, and the remaining 700 million will die in 10 years. Or what kind of mice eat genetically modified organisms to cause genocide, and humans are prone to cancer if they eat genetically modified organisms.

These are all fake!

The real problem is that allergic reactions in people can increase tenfold or more! Prone to offspring with 'weak constitution'! If the offspring cannot restrain the weak constitution and reproduce the weak constitution for more than ten generations in a row, there may be 'genetic defects'!

Moreover, genetically modified crops themselves are prone to extinction.

Even if it is not the use of scientific and technological means, but the use of hybrid means to cultivate crops, it is not absolutely safe.

Tang Hai paid attention to the problem of grain production in China last year, and the hybrid rice in several grain-producing villages could not bear fruit. I don't know if this is a problem with the genes of the grain species or if it is mismanaged.

Since then, there has been a policy of 'bold research and careful promotion' on genetically modified crops, and a group of people have clamored for the mass planting of potatoes to replace grains.

Mules born from horses and donkeys basically do not have the ability to reproduce offspring, which is also natural reproduction. There are risks associated with human species alteration, whether by scientific or natural means.

In the past, biology experts were only interested in plants, but in recent years, many scientists have added skill points to animals!

Cloning sheep was an old thing decades ago, and now the latest technology in the United States is the 'three-in-one' salmon.

The salmon on people's tables is Atlantic salmon, which is delicious but grows extremely slowly and is less resistant to cold and disease.

The American aqua_Bounty Company took the genes of Atlantic salmon as the main body, injected the cold and disease resistance genes of Pacific salmon, and then injected the super growth genes of the super-large salmon Chinook salmon......

A new breed of salmon appeared four years ago and grows 15 times faster than the average wild salmon in captivity! It's easier to gain weight than raising pigs!

The computer simulation program on the US side is very powerful, and the Food and Drug Administration FDa has concluded through computer simulation calculations that if this 'super salmon' is washed into the natural environment by the water like a carp, even if only one male swims out, he can easily find a mate to reproduce, and after a maximum of 40 generations, the natural salmon will be completely extinct, and then the superfish genetic problem will appear, and it will also become extinct.

No matter how much aqua_Bounty company emphasizes that it is a 'whole fish gene' and how much it emphasizes that it only cultivates female fish, FDa will hold on to it.

In terms of a single generation, the impact of genetically modified animals is not as good as that of plants, but ......

Animals can run!

The Americans are a group of 5 scumbags, and they can't even handle the carp, where do they dare to release super salmon out?

……

Tang Hai only has a slight idea of using the natural environment to transform aquatic creatures, at most it is equivalent to cultivating a mule!

The three people in front of them are obviously perverted environmentalists, just now everyone was talking and laughing, and now they are looking at Tang Hai with the eyes of class enemies, isn't this kind of breeding method used everywhere, and I haven't seen you crack down......

"I just asked casually, you guys are too sensitive!"

"Don, you ask, why do you ask this?"

"Oh, I have a fishing farm, I may have to move in recently, this big pike is my treasure, I wonder if I can take it to the sea to raise it."

A few people looked at the clothes on Tang Hai's body, and then looked at the all-wooden house next to him that was obviously very low......

"Brother, are you smoking too much?"
