It's no wonder that Tang Hai was so surprised, the fishing he came into contact with was 40,000 tons of cold-water shrimp in the United States, and 60,000 tons of king crab per year......

The number Jennifer just said was so surprising to Tang Hai!

My first reaction was that I had heard it wrong!

"Global seafood production in 2015 has dropped to 90 million tons, head."

"Are you a comic who has traveled through the era of global satellite releases?"

"The United Nations Food and Agriculture Organization FAO counted the results of 2012 in 2013, and judged that the global seafood production that year had dropped to 90 million tons, but then there were new statistics, many countries in order to catch more, reported to the United Nations when deliberately underreported the figures, in fact, it is estimated that that year should be over 95 million tons, global seafood production from 30 years ago, has been maintained at this figure ......"

"I can't believe the words of the United Nations!"

"China is also a member of the United Nations and has a considerable say, and you don't even believe in the figures approved by Chinese officials in the United Nations?"

"Then I believe it."

Tang Hai changed his tone so quickly, which made Jennifer roll her eyes for a while.

She buried her head in writing and painting again, but a woman has the talent of dual-mindedness, and she can chat with Tang Hai at the same time!

Tang Hai likes to observe, and has long found that men's concentration is relatively high, but women's ability to multifunction is really not covered, Jennifer once talked on the phone while driving, and did not forget to eat snacks, after that time Tang Hai did not let her touch the car, although she said that her driving level has improved and there is no need to be afraid, but Tang Hai does not approve of this road killer. You must know that she almost served the three heroes including her in one pot at the beginning......

Talking while calculating is a trifle to Jennifer.

"Based on the data I got, as well as my personal calculations. Seafood production is declining at a rate of about 1 to 2 percent per year, which doesn't seem like much. But there are two major problems. ”

"Major problems?"

"One is that the population grows too fast, and the per capita resources will fall further, so there will be more development, and the catch will be lower and lower, and then the cycle will deteriorate. One is that people target the fishing of precious fish species, which may cause the biological chain to be broken. ”

"It is impossible for the political axes of various countries to sit idly by and ignore this kind of problem, and besides, the ocean current is not one country and two countries, and the countries of the United Nations will also speak out."

"Well, that's it."

"Does that work?"

"There are 8.1 million square kilometers of land on a global scale. It has been designated as a marine protected area, and the total area is even larger than that of Australia. One of the better managed is Australia, with a population of more than 20 million and no shortage of resources, so 60 protected areas have been randomly designated, and the number of fish in the reserves has tripled. ”

"Then what's bad?"

"Peru is the hardest hit by El Niño, with a significant decline in anchovy populations, and Peru has taken steps to reduce its annual catch, but Peru's fisheries regulator is facing accountability. He also sighed and said, 'Technically, we should say that our annual anchovy catch quota should be zero'. That's the biggest problem in a lot of places, if they depend on the fishing industry to survive. Then they won't ban fishing. ”

This is an almost unsolvable problem, as many areas depend on fishing for their livelihoods, and it will take many years for the closure to restore marine ecosystems. However, it only takes a year or two for a fishing ban to bring down the fishing economy of a region, or even a country.

Jennifer draws a circle on the drawing. Then another circle partially overlaps it, and the second circle gets bigger and bigger......

"Organization for World Economic Co-operation and Development, Food and Agriculture Organization of the World Food and Agriculture Organization of the World Federation. The two agencies are confident that the fisheries will recover, and now that the sky is full of satellites, the oceans will be more regulated, and they expect the production of wild fish in the ocean to recover by 95 million tons by 2048...... To be honest, I'm not really optimistic about this! But I am optimistic about the other one, they expect that the output of artificial aquaculture will also reach 95 million tons in 2048, and the total production of seafood in that year will reach at least 172 million tons!

The first point is that I am not very optimistic about how well people can do in terms of survival, income, and so on, but I am optimistic about the second point.

Now that the catch is fixed, it's better to be cheaper than to be cheap. But you must remember what you promised me......"

Jennifer looked at Tang Hai gloomily.

"Get up and go out for a walk. Ordinary fishermen are free, but we are still here. Anyway, there are few people, so I just went to try that Korean food......"

The world's seafood production is actually huge, but a considerable part of it is not eaten by people, such as anchovy.

Cash fish, such as cod, can be farmed in the sea with large investments, as Greenland and Norway like.

If the bait is artificially grown, not to mention whether there is a health hazard in the diet of the fish itself, it is not cost-effective in terms of economic value alone, so the 'bait fish' such as anchovy is widely fished, and when the anchovy can no longer form a fish, the target will become a jade tendon fish or the like.

If people keep catching big fish, it will cause small shrimp, crabs, small fish, and jellyfish to have no natural predators, and the reproduction rate will increase, which is actually an acceptable marine damage, at most, it is 'seafood grade decline'.

But if people keep catching small fish, it will be very harmful.

This was originally a domino effect that Tang Hai thought could not be braked, but in the chat with Jennifer, he knew that there was actually a way to brake.

That's mariculture.

In the past, people were reluctant to do seafood farming, take Tang Hai's familiar milk _ mountain city business model as an example, the original fish farmers breeding clams, aquatic product buyers 5 yuan a kilogram and they buy, that is really stupid to focus on aquaculture, everyone went fishing......

Everyone went fishing, and the result was that there were no fish.

The fishery department of Rushan City thought no, elected the leading brother, and then hundreds of fish farmers united to carry out super-large-scale oyster farming, build an online sales channel, and sell it at a price of 35 to 40 yuan a kilogram......

Then Rushan City became China's No. 1 oyster breeding base.

In order to solve the problem of excessive sea fishing, it is necessary to large-scale marine aquaculture, and to solve the problem of low profits of marine aquaculture, it is necessary to get rid of the exploitation of layers of purchase, distribution and agency as much as possible.

Jennifer must have thought that Tang Hai could eat so much, and she would definitely be able to eat at the dinner table, so she planned to help Tang Hai build a seafood breeding base, and now she will try her best to help Tang Hai make money to accumulate capital when she goes to sea for all kinds of fishing......

'This is to make me a savior!' The U.S. fishery accounts for less than one-tenth of the world's fishery, and the value of dahlias accounts for less than one percent of the United States, and the output may not even be one-thousandth of the United States! It's not good for the world's ship kings to join forces to breed, she thinks so highly of me...... 'Walking on the snowy road, surrounded by snowmen, and there are people who put antlers in the snowman's head, and the people here don't think that deer antler is a good thing at all......

Slowly turning her head to look at the side, Jennifer didn't know what she thought of at this moment, and happened to look at Tang Hai as well.

Jennifer often gives Tang Hai a feeling like a sea elf, and with her pointed ears, she can go directly to shoot magic movies, not only in appearance, but also in temperament......

She smiled and was about to speak.

Bang!

A snowball burst open in her head!
