Zhao Xin also ate the big yellow croaker at night, this kind of delicacy that has no way to enjoy in the 21st century, is definitely commendable, and what he ate was a large yellow croaker of more than 10 catties.

This kind of big yellow croaker, if it is placed in the future generations, can definitely be sold at a sky-high price, one is equivalent to a car, or even a better kind of car.

About 7 catties of wild yellow croaker, if auctioned, can reach a high price of more than 130,000 yuan, 10 catties, it must go up a notch, 250,000 to 300,000 yuan, is his end.

But in this era, in Chinese waters, the big yellow croaker can be said to be overflowing.

There are not many natural predators, the natural and unique environment in the ocean allows them to grow unbridled, and the seaweed produced by the stable environment supplies the food chain of the entire ocean, which is a rich and beautiful place.

10 catties of fish, with 4 methods, some are unique to the Northern Song Dynasty, some are improved by Zhao Xin, in short, the taste of the big yellow croaker is undoubtedly commendable.

The taste of the large yellow croaker is delicious, and the other salmon, of course, is not bad, this kind has a name in later generations, salmon, salmon sashimi, which can be said to be a famous dish, especially salmon from the north.

This kind of fish mostly lives in the Atlantic Ocean, or the northern part of the Pacific Ocean, near the United States, and it is very lucky to be able to find this fish near the Dinghai Navy.

In the following days, the sea ship continued the sea trial, but on the second day and the third day, there was no such good luck as the first day, the second day barely reached 120,000 catties, only about 4 percent on the first day, and on the third day, it was reduced to 50,000 catties at once, only about one-sixth of the first day.

Next, with a slight pick-up, with the help of the fishermen, they slowly found the trick that where the monsoon and the ocean currents meet, there are more fish stocks.

It's a pity that in the vicinity of Dinghai, at least within the range of 600 miles, there is no super big fishing flood, similar to the previous big yellow croaker is a lucky, the largest fish school is only about 90,000 catties.

However, there are a lot of small-scale fish schools, and 3 boats can basically reach the level of 9 to 120,000 catties, which is also the daily output per day.

120,000 catties of fish, in the big fat pig, taking 200 catties as an example, it is almost 600 heads, which is really a lot, but compared with the Dinghai Navy, it is still a drop in the bucket.

Fortunately, the 7-day training has been completed, and 3 ships have been put into operation one after another, and they continue in the footsteps of their predecessors, and the first batch of these crews have gradually become familiar with the entire fishing process, they are already familiar with it, and then around the Dinghai Navy, there is a bit of a waste of the performance of the big ship.

The fishing boat that goes to sea, even under the premise of a tailwind, is only 11 to 12 knots of speed, three or four hours, it is only about a hundred miles, back and forth, that is, 8 hours, a day, 14 to 15 hours, or summer.

The actual time spent on fishing may be five or six hours, which is very inefficient.

Three ships, with a total capacity of 1,000 tons, can only get back tens of thousands of catties at most, which is not efficient.

Zhao Xin actually reminded them that there is no fishing ground around the Dinghai Navy, and the nearest one may be four or five hundred miles away, and the luck of the first day is really lucky, and the next day is like a blow to the head.

Fortunately, they are already familiar with it, whether it is for boats or fishing, under the premise of ensuring safety, they can sail relatively far.

At present, the support force of the Dinghai Navy is not perfect, because it is rooted in the relationship between the islands, at most, it is in other ports to obtain some territory that can be operated, and there is no way to provide comprehensive support for the Dinghai Navy, but some simple commercial activities are possible.

In the previous operation in the Ryukyus, the warships did not dare to go inside at all, and they sailed directly, which was quite dangerous.

Fishing boats are more than a grade lower than warships, so if they sail directly, they will be more dangerous.

Fortunately, there is no problem with the fishing boat, even if it is a larger fishing boat, it is also a fishing boat, when all the catches and other things are revealed, what is the problem, even if it is paid attention to by someone who cares, it will not reveal a lot of secrets.

With the Dinghai as the center, the direction of heading is mainly downward.

In China's coastal waters, fish schools are basically concentrated at the estuaries of major rivers, such as the Haihe River, the Yellow River, the Yangtze River, the Pearl River, and so on.

These rivers are all large rivers, and when they enter the sea, they carry a lot of water, and their impact is quite strong, and their impact will wash up the nutrients on the bottom, feed the plankton, and attract a large number of fish.

This is the activity of living things, just like in the dense forest, where there are streams, most of the most dangerous places, the reason is very simple, any animal needs to drink water, this is a problem that cannot be solved.

The herbivores wanted to drink water, and they attracted carnivores, not because they didn't know the danger, but instinctively, they still let them come, and because of this, this became a hunting area for predators.

The same is true for fish, in the sea, plankton is the food of many organisms, especially in large quantities, and fixed, it becomes an area where you can hunt, and the many fish attracted according to the food chain form a relatively dense fishing ground.

The scope of this fishing ground is almost all over the Yangtze River estuary, almost a few hundred square kilometers, and a large number of fish are distributed, and there are even some large-scale fish schools.

Once you arrive, as long as there is no typhoon or other bad weather, you can fish for a long time, perhaps, there is no way to bring back fresh fish, but the harvest is many times the previous scattered luck at sea.

As early as when Zhao Xin decided on the strategy of developing fishing boats, Zhao Xin had already realized this, and the Yangtze River estuary may become the core of future fishing boats, so he built some supplies in advance.

Now the mouth of the Yangtze River is still a relatively remote place, the famous Shanghai Port in later generations is still a wasteland, in the land of Shanghai, belongs to Huating County and Kunshan County, the Chongming area of the estuary, belongs to Haimen County.

Because of the relationship of time, the later generations continued to increase, Chongming Island, the third largest island in China, is still just a small sand dune, Dongsha and Xisha appeared in the Tang Dynasty, and then began to be settled, and then in the third year of Tiansheng, the two sands combined to form a larger land.

It is said to be large, but it is smaller than the Dinghai Navy, that is, a few square kilometers, and the side is not so strong, and it does not have the conditions to become a seaport.

Not to mention Chongming, even if it is Shanghai, it does not have the conditions, the Shanghai of later generations, is the Yangtze River after thousands of years of washing, and finally formed, this era, the Shanghai Port of later generations, is still in the sea.

Shanghai is no way, but further inside, along the Yangtze River gradually in, that is a series of cities, for example, Chongzhou, this is the name of Nantong in later generations, as early as the Tang Dynasty here is an important port, to the Song Dynasty, maritime trade, as well as the prosperity of inland river transportation, but also he here continues to develop.

Such a throat in the Yangtze River basin is also an important port, and the Dinghai Navy has already laid out and built a warehouse wharf for inventory and transshipment.

Now, when fishing boats can go to the vicinity of the Yangtze River estuary and fish, it is natural that this place is also used as a turnover center.

At this time, the Yangtze River Delta, has not penetrated too far into the ocean, the current Yangtze River estuary, to Chongming is not far away, Chongming's current name Haimen, from Chongzhou, only less than 100 miles.

It is ideal as a transit point and a temporary port of call, with the speed of the sails, it can be reached in a maximum of 3 hours, whether it is sheltered from the wind or temporary repairs, there are not too many problems.

Similarly, it is also a window that radiates the entire Yangtze River Basin, in the commercial field of the Dinghai Navy, and also knows the price of sea fish in the Northern Song Dynasty, located in a series of ports in the Yangtze River Basin, for example, Chongzhou, such as Jiangning, and then Changzhou and Suzhou, these places where countless romantic wealth are concentrated, can indeed be used as a sales place.

This is just a simple assumption, in the Northern Song Dynasty, in the era of no freezing technology, natural fish catch, preservation is not easy, pickled fish is not everyone likes, this kind of sales, must be some minds to the East.

Although the Yangtze River basin is relatively rich, it is not like the Dinghai Navy, where a large number of people with strong purchasing power are concentrated, 300,000 catties of fish, two or three hours, can be digested in the Dinghai, but even the richest Yangzhou, how much can it digest.

The sales are just for some high-end fish, such as the delicious one, or under the leadership of the Dinghai Navy, the trend generated, such as crabs and lobsters.

These things, although the legend has been popular for a long time, but crabs were gradually spread in the Qing Dynasty, as for lobsters, there were no lobsters in ancient China, which were native to the Americas.

These are all later words, the 3 ships, in addition to the need to catch a large amount of fish, to increase protein for the Dinghai Navy, as well as vitamin A intake, the same is also for the follow-up ships to play a front station.

In the next 15 days, there will be 17 ships to complete the sea trials, they will come to the Yangtze River estuary one after another, 3 ships are almost 1,000 tons, 20 ships, that is, more than 6,000 tons, such a huge catch, only the Yangtze River Estuary can continue to withstand for a long time.

In the next three months to half a year, Dinghai Shipyard will continue to expand and produce, and it is expected that 6 batches of friends will be launched, at least 300 ships will be launched, and the total tonnage of fishing will reach 100,000 tons.

It sounds terrible, but in fact, this tonnage is really not much, even if a full load is completed in 3 days, it is only 10 million tons in a year, this number, I am afraid that it is not as good as the years strictly controlled by later generations.

In the 21st century, when the East China Sea is said to be fish-free, the amount of fish that can be regenerated under strict restrictions is about 5 million to 8 million tons, and the actual catch is 13 million tons, which is the result of control.

At the beginning, when the East China Sea was developed, the total amount was probably more than three times.

Without pollution, the huge fishery resources accumulated over thousands of years and eventually formed, not to mention reaching 30 million tons, are conservatively estimated at 10 million tons, which can still be expected.

Even if the future of the navy is determined, the population reaches 10 million, 10 million tons, it can ensure that a person can eat one ton a year, this figure is more terrible than food.

In fact, each person eats less than a ton, although the fish is good, but eating too much, it is not good, just take a country that likes to eat fish very much, the per capita intake of fish in Japan is about 28 kg to 30 kg, that is, 60 catties of fish per capita per year.

Calculated from this, according to the total population of 100 million in the Northern Song Dynasty, it will take about 6 billion catties of fish, and if converted into tons, about 3 million tons, a single East China Sea can easily support it, not to mention other sea areas, even Hokkaido.

The intake of a large amount of fish can not only reduce the consumption of food, the calorie of meat is higher, and if the intake of meat is more, the per capita food consumption will be reduced, and the same will reduce the deficiency of various vitamins, especially the problem of vitamin A.

Speaking of the future, it is a little far, fishing boats, but the initial development direction of the navy, but not all the development direction, this is very useful in the initial stage, can obtain huge benefits, and transform the nutrition and security of the entire navy, but the real decision on the future development of the navy is still warships and merchant ships, the reason why they are not the focus, is also because of the limited tonnage of the initial construction.

Shouldering the hope of the whole Dinghai Navy, after having other ships take their place, the three ships set sail again, compared to the first voyage, this time, they walked very easily.

After a month of running-in, the sailors have become familiar with the operation of the fishing boat, except for the fishing and net lifting, which needs to cooperate with the fishermen, other times, it is no different from an ordinary boat.

The sails on the huge fishing boat caught enough wind and then quickly headed south.

The nautical chart of the Dinghai Navy has not been thoroughly perfected, and it is only in the Dinghai Navy as the core, and the surrounding 500 miles are clear, and the Yangtze River estuary is a little farther, but Chongzhou and Haimen are one of the few two very clear places.

When sailing in the ocean, especially when there is such a huge target as the Yangtze River estuary, as long as the general direction is correct, it will not be wrong.

Dinghai is far from the mouth of the Yangtze River, almost eight or nine hundred miles, which is almost thousands of miles, for the average person in the Northern Song Dynasty, this is a relatively long place, maybe the average person takes a carriage, has to walk for more than half a month, walking, it is even slower, a month is also ordinary.

But now, in front of the sailing boats going downwind, this is not a problem at all, and the speed of 12 knots an hour makes it close to 20 kilometers in an hour.

At this rate, it will take up to 45 hours to reach the mouth of the Yangtze River.

The arrival time, a little slower than expected, plus dodge and rest, not all-weather driving, a total of 4 days, finally arrived at the mouth of the Yangtze River, looking at the white river, converged to the ocean, the collision and waves generated by the two sides, sighed again and again.

has arrived at the location, Zeng Da Niu and they have already begun to look for the location of the fish, I believe, friendly news will come soon.
