A sudden battle, because of Zhao Xin's intervention, once again calmed down, whether it was the identity of Dinghai Marquis, or Zhao Xin's contribution to the Dinghai Navy, his words, in the Dinghai Navy, are true.

Zhao Xin didn't explain too much, just told them that fishing boats could get a lot of fish.

These officials of the Dinghai Navy do not know the structure of diet because of their vision, but the Dinghai Navy is now almost plagued by food.

As far as China as a whole is concerned, food as a whole can achieve a balance of payments, otherwise, it will not be able to feed so many people, this is a natural choice, people must have basic food to survive, in order to survive.

However, this balance of payments is not evenly distributed, and there are many regional imbalances, and because of the development and natural conditions in the south of the Yangtze River, there is more grain than in the north, and it is much more.

In the past, in the north, for example, the Qin and Han dynasties, and even the foundation of the Tang Dynasty, the Guanzhong region, because of the perennial development, coupled with climate changes, is no longer enough to support a huge population, and the once rich Guanzhong has become synonymous with poverty, otherwise, how dare the Western Xia be so rampant.

After the Song Dynasty, the Yellow River gradually elevated, the rich Central Plains, became a barren place, the Beijing-Hangzhou Grand Canal is important, he is not only the commercial line of the Northern Song Dynasty, but also the lifeline.

Every year, through this canal, grain from the south of the Yangtze River is transported to Bianliang and the huge cities in the north, otherwise, there will be a large-scale shortage of grain in the north.

The same is true for the Dinghai Navy, which is even worse than the northern part of the Northern Song Dynasty, for the simple reason that the Dinghai Navy has a small land, coupled with the land that industry and population compete for, there is no place to grow grain at all, and the grain self-sufficiency rate is zero.

The Dinghai Navy is very profitable, and similarly, it has a huge transportation capacity and can get a large amount of grain from the south of the Yangtze River to ensure the needs of the Dinghai Navy, and the problem of food and clothing is not only guaranteed, but also more than enough.

However, with the development of the Dinghai Navy, after the Dinghai Navy gave the workers high salaries, it was natural that they would put forward higher requirements.

The most intuitive thing is meat, ordinary poor people, the best thing to improve their lives is meat, the appearance of a piece of meat will even make the whole family, from adults to children smile.

In the past, there was no way, even food could not be eaten, let alone meat, the Zhuang family, in addition to cultivating the land, also as much as possible to find other income, will also save, unless it is a festival, otherwise will not spend money casually.

When I arrived in Dingjun, maybe at the beginning, I still maintained this habit, but as I stabilized, the necessities of life that should be purchased have been purchased, the children have also gone to school, and the improvement in life has almost come.

Meat has become the most demanding, and in large markets, meat stalls are the most crowded and the easiest to sell out.

However, meat has always been very tight, because of Zhao Xin's care and the ease of Ding Haijun, the price of meat has not risen, but the total amount is not high, except for the allocated meat tickets, there is very little meat that has been scattered inflow.

After all, Dinghai is an island, even if someone knows that this can make money, they don't have the ability to transport it, and if they transport it privately, they will be discovered on board.

If it is said that it is one or two thousand people, the increase will increase, and some elite troops in the Northern Song Dynasty also do the same, and the elite troops in the forbidden army can even ensure that each person eats meat every day, otherwise, it will not be able to support the huge consumption.

However, the current Dinghai Navy is not simply 10,000 or 20,000 people, this is a huge number, 2 million people.

If according to Zhao Xin's requirements, every day, non-staple foods other than grain, such as poultry, eggs, vegetables, fish, etc., must be guaranteed to reach 2 catties, but 36,000 stone per day, which is almost not less than the consumption of grain.

This is simply impossible, according to a pig 2 stones, the daily consumption can even reach 18,000 pigs, 540,000 a month, it can't be said that the entire Northern Song Dynasty, there are not so many pigs in the country, but if it is really a few months, there are so many pigs in the Northern Song Dynasty.

If all of them are supplied to the Dinghai Navy, it will definitely cause turmoil in the entire Northern Song Dynasty, although pork is not the best meat for the nobles in this era, but it is also the most sold, the lower level among the nobles, ordinary people, servants and soldiers, they can only eat pork if they want to improve their lives.

Zhao Xin is also making efforts, he is using the relationship of promoting agriculture to build some farms in various places, without feed, with the help of some miscellaneous grains, bran, and the rhizomes of some plants that can be used, which can ensure that the feeding is at a lower cost, centralization and captivity, which will make the growth of meat a little more.

This is a long-term mechanism, which will slowly increase over time, and about 10% of the meat that is now supplied to the entire Dinghai Navy is provided by these farms.

This proportion is not large, and it will not affect the overall situation, but the Navy will spare no effort to promote, and concentrated breeding is the direction of meat growth, because it is more efficient.

In addition, the Dingjun Navy also has contact with the Northwest, and Han Qi has a good relationship with the Dingjun, so there is no problem with this.

Han Qi promoted the development of the northwest and opened up a huge water conservancy project, which can add a huge amount of land to the northwest, but the most that these grains are to maintain a slight surplus in the northwest, and the real money in the northwest is farming.

The natural grassland in the northwest, if not used, is really wasted, simply from the Western Xia cattle and horses, in the semi-stocking method provided by Zhao Xin, the efficiency is at least several times higher, such a huge output of meat, for the northwest is also a pressure.

Maybe let Han Qi support Zhao Xin and regain the throne, Han Qi will not do this, but doing business with the Ding Navy, this is no problem, as long as the money is in place, even war horses can be used, let alone cattle and horses.

Cattle and horses in the northwest, that is far from water can not quench the thirst of the near, a road from the northwest to Bianliang, directly restricting the efficiency, to Bianliang, the Ding Navy has begun to refit, some large, can be the greatest possible load of cattle and horses of the ship, has begun to transform, a little extreme, can even slaughter cattle and horses, pickled and transported, so that the efficiency is higher.

Before solving the problem of whether there is a problem, consider what kind of taste and the like, that's a joke, people are hungry, I'm afraid even Guanyin soil will eat it, not to mention the taste.

When Zhao Xin did not change, the natural demand of the Navy made the demand for meat very strong, not to mention that now, Zhao Xin thought of vitamin A, which can not only treat night blindness, but also to adjust the dietary structure, increase meat and non-staple foods, and reduce the intake of carbohydrates such as food, so that the physical fitness of these people will be improved.

Protein intake, on behalf of the basic quality of people, but also represents some natural strength, why the northern nomads, whether it is strength, or other aspects, are higher than the farming people, some people think that it is the relationship of race, but in fact, it has a lot to do with the intake.

Even if it is a poor herdsman, the natural environment, meat has become their main intake substance, maybe eating too much meat, will not digest, will be tired, but it is very useful for the growth of body muscles, which is also the basic reason for the higher physical quality of the northern nomads.

The Northern Song Dynasty didn't know this, but Zhao Xin knew that he had already prepared to improve the dietary structure, which had already begun when he was in Baozhou, and the steamed bun shop at that time, making money was only one aspect, and increasing the intake of protein and meat was also an important reason.

It's a pity that such a move, after arriving at the Dinghai Navy, there is no way, when the number of people reaches a certain level, many very simple things become complicated.

One person adds 1 tael of meat, which is 200,000 catties, which is 1,000 pigs, when this demand is strong, even if Zhao Xin has a gold finger like a card system, it can't be changed.

Now, the ocean has opened a door to the Ding Navy, in the eyes of others, the ocean is unpredictable and full of all kinds of dangers, but in Zhao Xin's eyes, the ocean is a treasure trove full of all kinds of hopes.

，

This wave fishing, to a certain extent, does not have any cost, as long as you find a school of fish and catch it.

Perhaps in later generations, because of the depletion of fishery resources, it will take a long time for the boat to find the fish, even with the help of radar or something.

But in this era, marine fishing has not started at all, and the fish are in a fixed location, as long as you find a place where the ocean currents meet, or where the river flows into the sea, you can do it.

The entire ocean, which is not polluted and not overfished, is conceivably reaping huge benefits.

Even if these aspects, even if they were very dissatisfied with this resolution, in the end, they still agreed to Zhao Xin's request, even if they didn't know anything about this request.

There is no doubt that Zhao Xin's will has been specially implemented in the entire Dinghai Navy, as a doctor of liberal arts, he does not know science, nor does he know what form the fishing boat is.

But a simple trawl, I still know, even if I don't know it from the net, look at the northeast side, salmon fishing activities, you know what it is, it is a huge net, can be spread on the bottom of the sea, and then dragged by a fishing boat, and finally the net is closed.

A trawl net, compared with ordinary fishing nets, spans a larger area, and the use time is longer, but it can hold up more catches, then, some cranes, can still be equipped to the boat, which can reduce the use of personnel.

Fishing nets, in later generations, are mostly made of composite materials, which are light in weight and have good toughness, and at the same time will not absorb water, will not be corroded, and can be used for a long time.

In this era, fishing nets were mainly made of flax, which would absorb water when it entered the seawater, and the material would change, and it was easy to be eroded by water.

Of course, Zhao Xin knows the problem of flax materials, but he has no better choice, if he can make chemical fiber, or nylon materials, there will be no problem.

However, Zhao Xin is not without a solution, because the card system can synthesize a large number of things every day, among which organic matter is a long process, and until now, no useful organic matter has been synthesized, but there is a material in it that can block water.

It is a material similar to oil that, when combined with flax, fills the flax material and prevents water from entering.

Such a material, it is impossible to completely isolate the flax from the water, but it has a great effect, once painted, the flax made of fishing nets, can be used for a longer time, which will become the basis of the fishing net.

Linen was widely planted in the Northern Song Dynasty, and most of the ordinary farmers' clothes were made of this material.

After being painted, and then looking for fishermen to compile, this is not a problem for the Dingjun.

At the beginning of the establishment of the Dinghai Navy, a large number of fishermen were absorbed, and for the fishermen, the conditions given by the Dinghai Navy were very high, and they were willing to change, so they followed to the Dinghai.

Later, they lived well in Dinghai, and although they left the sea, there was no danger, and their living conditions were higher.

Now that the navy has returned to the sea, these former fishermen have also entered the water transportation system, and many of them work on river boats or sea vessels.

It's only been 2 years, and the fishermen haven't forgotten their roots, of course they know how to weave fishing nets, and the materials given by the Navy are better, some of the original problems, most of them have been solved, and the only thing that needs to be considered is to expand the fishing nets.

Trawl nets must be very large, a few hundred square meters, or even more, it is possible, only a large enough net can net enough fish to increase efficiency.

In the middle, in addition to the original weaving skills, but also to consider the bearing capacity, Zhao Xin proposed, using tougher steel wires, as the warp and weft threads, they bear the most important weight, and the fishing nets are attached to them.

Zhao Xin also proposed some floats and some signs based on what later generations saw, so that when fishing, the location of the fishing nets could be identified through these.

Once these basic steps have been solved, it is necessary to try how to release the net, how to lay the net, and how to tighten the net in some way, which can be done according to the tank experiment and the exercise.

Fishing net fishing, to put it bluntly, is to cover a part of the water area with the fishing net, through the hole in the fishing net, the water is sent out, and the rest, which cannot be out, is the catch.

There is no essential difference between trawl nets and ordinary fishing nets, he just puts them larger, thousands of square meters, or even thousands of square meters, which can envelop a very large sea area.

In the ocean, once you encounter a school of fish, a net down, there may be thousands of fish, even if a fish only weighs one or two catties, this is a few tons, or even dozens of tons of harvest.
