Chapter 1791: Marine Cultivation
As the last hope of the world's food, the ocean not only has greater possibilities, but also once the marine environment improves, all kinds of organisms between regions are a comprehensive promotion, if from the perspective of the vision, any penny can be invested, you can get ten times, even a hundred times the benefits.

The process of moving towards the ocean, at the very beginning, was just a coincidence, under the premise that agriculture has developed to a certain extent, some marine experts proposed to ask for the ocean.
Ask for the ocean, of course, not fishing, fishing is the easiest, as early as countless years ago, even in the slave society, and even in the primitive society, there were people by the sea, asking for the ocean, in most cases, the ocean is generous, as if the fish never end, but for the scientific and technological conditions at that time, marine fishing is a point of no return, the ocean is different from mountains, rivers and lakes, no wind and three feet of waves are said to be the ocean, a little bit of wind, for ordinary boats, it is a nightmare, People are not fish, water is only relatively speaking, in the wind and waves, not many people can survive.
With the performance of the boat is getting better and better, the offshore fishing is getting safer and safer, especially the emergence of trawlers, which directly makes marine fishing the norm, but such large-scale fishing, more than the balance of the ocean itself, later China, no fish in the East China Sea is not an exaggeration, that is real, on the one hand, the impact of pollution, this aspect, but will be gradually digested by the ocean, the real impact is trawlers, countless trawlers, like locusts, fishing in the ocean, Caught enough fish, enrich the diet of the whole China, but also intensify the marine ecology, for example, the East China Sea's specialty large yellow croaker, before the 50s of the 20th century, is a group of appearance, but after the 90s, gradually rare, to the 21st century, almost no wild.
It is for this reason that when oceanographers put forward the proposal to study the ocean and plant seaweed on the continental shelf, Yang Yuanzhao directly agreed, and even after some people criticized it, saying that the investment was huge, Yang Yuanzhao also undertook it, in order to make the ocean rich and not repeat the mistakes of China.
At present, in China's four major inland seas, three inland seas have been developed, and the governance is good, with a total of 700,000 square kilometers of sea area, which almost accounts for about 60% of the area of the three major inland seas, but only about 35% of the final results, which has been the result of careful research by oceanographers, but such 200,000 square kilometers of sea area, has achieved excellent results, which is also in recent years, not only no one is criticizing the huge investment in the ocean, because the output of the ocean has made them see hope.
More than 20 square kilometers of seaweed has become one of the largest fishing grounds in China's coastal waters, and the annual growth rate of fish catches in these areas has reached more than 70%, which is still a sustainable annual figure, and the fish catch production of the entire Chinese coastal waters has also increased by 30%, and in the midst of rapid growth, which is very helpful for balancing China's diet, and creating a lot of profits and jobs.
Such a result, even the initiator Yang Yuanzhao did not expect, he just learned these things from the Internet in the past, at that time it was still in the United States, the United States in the West Coast North Atlantic region, a large number of seaweed, and even the kind of biological blanket specially used to gather seaweed, can effectively improve the survival rate and survival rate of seaweed.
Of course, the march to the ocean is in the 21st century, at that time, not only the labor cost of the whole world has risen to a terrible situation, coupled with pollution and the destruction of the entire ocean community, so the investment is so huge that even the United States can not afford it.
However, this is not more than 100 years ago, when industry has not completely changed the environment of the whole earth, the entire world's oceans have not been polluted, and the ecological balance of the entire ocean has not been weakened.
This supplement, so that China's marine ecological environment from a slow weakening to strengthening, with the gradual formation of a submarine forest, the natural ecological balance has been formed, except for a small part of the need to replant, as long as the monitoring can be, when the seabed algae forest, reached more than 60% density, will grow at a rate of 5% per year, will expand outward, this expansion is like the natural expansion of the forest.
This expansion is very considerable, especially when the seaweed community reaches a certain level, more than 500,000, or even 1 million, 5% per year is equivalent to laying 50,000 square kilometers of seaweed every year, so the benefit is very huge, the seaweed area increases by 5%, not the catch increases by 5%, the catch is very special, the better the environment, the more fish are attracted, many of which are rare, even the total amount of fish will increase a lot, the seaweed can undertake the task of nutrition, is the entire ocean, and even the basis of human activity.
Because of these harvests, China's seaweed planting, has been gradually expanded from the Chinese domestic sea, in the South China Sea began to be planted in the South China Sea last year, relative to the three major inland seas, adding up to only more than one million square kilometers, but the South China Sea is 3.5 million square kilometers, although the area of the continental shelf, not all, but can be planted a large number of seaweed, although most of the seaweed is grown on the continental shelf, but in the deep sea, there may not be no plants, most of the South China Sea is deeper than the continental shelf of 200 meters, but it has not reached the deepest point, Seaweed can be grown in larger places.
China has not only four major inland seas, after occupying Southeast Asia and Australia, the continental shelf is vast, especially in 1917, China tried to start planting near Hokkaido.
This is a pioneering achievement, even in later generations, Hokkaido is one of the world's four largest fishing grounds, but more rely on the interaction of ocean currents to form a fishing ground, if enough seaweed is cultivated, it can form a relatively stable food structure for fish, increase the aggregation of fish, and increase the density of fish in the fishery.
Other places are also being planted, the islands of Southeast Asia are densely populated, the number of continental shelves is more, and the development itself is less, after planting a large amount of seaweed, it will definitely be upgraded to a certain level, and they will become one of the gathering places of fish in the ocean, attracting fish from the deep sea, and even creating a biome. In the future, this cultivation will expand to the islands of Oceania and the Pacific Ocean, and will gradually form a complete biozone among the seaweed-based flora and fauna, increasing the chance of ocean formation.
The road facing the ocean, is not easy to walk, this point, China is also clear, with China's current industrial output value of several times more than other industrial countries in the world, every year from the countries to obtain a large amount of capital and raw materials, still feel that this is a very difficult, even if it has now been gained, the annual growth of the catch of the three major inland seas is an astronomical growth, but if this growth can continue for 10 years, 10 years of fish growth, may only be half of the overall investment, This is still because we will not continue to invest, and if we continue to invest, the time to recover costs will continue to increase in the future.
To China's economy, the fear is never low profits, but the direction of capital investment, which is also the fundamental reason why this plan has been implemented and implemented, 20 years to recover the cost, it seems that the annual income is only 5%, but this absolute income is very terrible, the most important thing is that China calculates only the absolute income, only the calculation of the fish itself and the income of seaweed harvesting, and does not calculate the derivation of this, such as some of the value of seaweed that China does not realize. Later generations of researchers extracted beneficial ingredients and medicines from seaweed, and even studied the extraction of oil from seaweed.
These are long-term benefits, even from seaweed to improve the ecological environment, access to oxygen and other benefits, this income is definitely not low, even if it is not derivative, an investment of more than 5 trillion Chinese dollars of the project, even if it is 5% of the income, this absolute value will be more than 250 billion, which is difficult for any large state-owned enterprise or group to create, not to mention that the aquaculture industry is a century-old industry, as long as the seaweed is balanced, the future does not need to invest, you can continue to obtain income, hundreds of thousands of square kilometers, Even one million square kilometers of land, this 5% expansion rate, the chain benefits created by this alone, let the whole plate increase, not to mention the final income, just from a 5 trillion plate, an increase of 5% per year, which is another 250 billion, which is not bad.
It's just that 5 trillion yuan has been invested in the three major inland seas, and the South China Sea is at least three times more than that, near Japan, the North Pacific, the Aleutian Islands, near Australia, and the southwest Pacific Islands, the scope of these continental shelves is far above China's inland seas, and all the investments may be 10 times or even more than 20 times that of the three major inland seas.
For a country, there is a lot of money to a certain extent, just a number, the key is materials, manpower, and even resources, these can not be changed casually, even if it is as strong as China, it can only come step by step, starting in the South China Sea in 1917, and testing the waters in Hokkaido, Southeast Asia, Australia, and even the continental shelf of the Pacific Ocean, can only be used as a pilot, the focus is more valuable, and the rest can only be slowly figured out, conservatively estimated to take 20 to 30 years, As for the maintenance and update, it will take more than 100 years.
