At present, the Dingjun Navy is completely different from two years ago, and the Dinghai Navy two years ago, it can be said that every step needs to be completed by Zhao Xin, and even the basic research projects are no exception.

In 2 years, in addition to allowing Zhao Xin to build a series of factories, it also allowed the Dinghai Navy to form a tradition of research, a simple trawl, of course, there are special people to study, and even the fishing boat itself will be adjusted.

Combining the trawl with the fishing boat will modify the superstructure of the ship, and this modification is not on the ship, but through the model, the needs of the use are analyzed, and the most reasonable layout is not known.

The Dinghai shipyard has once again received attention, and the progress of 20 ships, with the help of a large number of people and machinery, has been greatly accelerated.

In order to speed up the speed of these ships, some skilled workers in other shipyards have also been temporarily transferred, and the entire Dinghai shipyard has doubled its personnel, and the efficiency is of course faster.

The pursuit is not a large-capacity cargo ship, but also a warship with sufficient combat effectiveness, and when the fishing boat is the target, many aspects can be pursued not so high.

The 3 ships were built at the fastest speed, and it took only 7 days to complete the subsequent construction, and the superstructure was also adjusted according to the designer's design, and the whole ship type was quite different from before.

When it was completely completed, Zhao Xin also came to watch the ceremony, and the seemingly simple fishing boat was actually very important for the current Dinghai Navy.

At this time, in the final end, in the era when there was no anti-rust paint, the ship would be brushed with a layer of tung oil to waterproof, and the new ship had a huge smell of tung oil, which was not particularly good.

Some ships of later generations, after the initial completion, still need a few months to a year of sea trials, but you know, this is not the first time that the Dinghai Navy has gone to sea, but many times, more than 20 experimental ships, has been aimed at their respective places, a series of changes, under such changes, recruited a large number of sailors for testing, some tools, also tested, mainly to see whether it is suitable, on the sea, how to use.

After a simple ceremony, the sailors and captains began to board the ship, and they were put together from all sides, although it was a fishing boat, but it was necessary to go deep into the ocean, so there must be skilled personnel, and there were also experienced fishermen.

The role of fishing boats is to fish, experience is very critical for fishing, these fishermen, they may have been engaged in fishing for more than 20 years, in the perennial time, maybe for marine fishing, there is no experience, but to identify the type of fish, to identify some fish schools, they can still be.

The 12,000-material ship is very large, and the goods that can be loaded are at least more than 18,000 materials, and according to the tonnage, it can carry hundreds of tons of things.

At this time, even the latitude and longitude lines have not been completely completed, it is still too early to sail the ocean, explore the waterway, etc., but it is still possible to wander around the neighborhood.

For economic and efficiency reasons, Zhao Xin did not go directly to Hokkaido, a natural fishing ground, and his goal has always been very clear, and the vicinity of the Yangtze River estuary is the best choice.

In this era, the rivers and lakes have not been polluted, and the ecological environment of the ocean is good, especially the four major inland seas of China, and various fish resources are very rich. Although it is said that there are countless people who are fishing, those fishermen, at most, are within 10 miles from the sea, and if they go far into the ocean, it will be very troublesome and very dangerous.

For fishermen, they know that in the deep sea, the chance of catching fish will greatly increase, and in some places, there are fish nests, and an adventure may make a lot of money.

But for the fisherman, unless he really can't live, otherwise, he will definitely not choose this path, rich income, which means that the danger is very great, those who end up gambling for money, in the end, almost nine times out of ten, are dead in the sea.

The reason is very simple, the farmer's fishing boats, several of which are specially built, most of them, are carpenters from fishing villages, or they are made by themselves, these boats, maybe in the near sea, are nothing, once they go deep into the open sea, they generally start a little bit of wind and waves, and they are finished, even if they successfully enter, they can find fish.

The big ship of all materials is different, or a special sea ship, it must be different.

Of course, Zhao Xin will not make this boat, do fishing boats to transform, but play a role in the process of exercise, as a consulting era over, Zhao Xin is very clear, only at the mouth of the river, there will be a large number of fish.

All kinds of plankton from the interior, as well as nutritious things, these rush into the sea, and some things on the bottom wash up, which will allow a lot of plankton to breed, and most of the torpedoes, are plankton sanitation, plus a food chain, there are more fish.

With a little pointer, plus some excellent fishermen, a boat with a full crew, a total of 3 boats, forming a fleet.

Two boats, fixed with a lot of machinery, for the release and recovery of fishing nets.

With the strength of the trawl, the large trawl, a net down, if you encounter a school of fish, a net down, may cost 10,000 catties, or even more fish, such a net, can not be pulled up by manpower, must use a variety of tools.

The trawl is characterized by the release of the boat, a huge net, slowly moving in the seawater, in places where there are many fish, it can be driven at high speed, and then slowly tightened, and finally the fish are caught.

The speed of a few knots, for some high-speed fish, is nothing, the elves in the sea, sailfish, can even reach the fastest speed of 190 kilometers, but most of the fish can not run over, simply a net to scatter, with a trawl, search an area, the efficiency is not the same.

Of course, the ship has also undergone certain modifications, and in some places, specially set up cabins, some of the more cherished, must be alive to be able to sell high-priced fish, which can be raised here.

This part, mostly at the bottom, is modified with ballast water to ensure a certain degree of breeding, such fish, in the entire ocean, are a minority, and those who specialize in releasing such fish are also restricted.

For such a large fishing boat, the amount of fishing is very large, and it is possible to go to sea at a time, operate for several days, or even ten days, and it is necessary to catch enough fish.

Fish is high in protein, whether it is a freshwater fish or a saltwater fish, as long as it dies, it is easy to rot and spoil, and some even a few hours, there will be problems.

Most of the distant-water fishing vessels of later generations are integrated fishing vessels, which not only have cold storage, but also have a production line to process fish catches even inside the fishing boats.

Freezing, is a very effective method, and it is also a common method in later generations, as long as the fish is simply processed and thrown into the cold storage, it can be kept fresh.

In this era, there is no refrigeration device like a freezer, although Zhao Xin has already made saltpeter and nitrocellulose ice, which can still be made, but it is not necessary to use it here.

Saltpeter, for the Dingjun, is a very expensive thing, the development of thermal weapons and artillery, no matter how much gunpowder is not too much, there is no need to waste it here.

Similarly, using saltpeter to make ice, you can simply make some snacks and the like, hundreds of thousands, or even more fish, to completely freeze, it will take more than ten or twenty days, this consumption is too great.

Since it is fishing, then it is necessary to consider the economy, and if the economy is not strong, it will be a waste of effort.

Fortunately, even if it is not frozen, there is no way to ensure these fish, and a very simple way is salt.

Pickling, which started very early, since the beginning of salt, is a method that has begun, when perishable meat, or other things, as long as they are salted, can be preserved for a considerable period of time, which is the easiest and most straightforward method.

Salt was of great significance to the Northern Song Dynasty, and at its peak, one-third or even more of the financial revenue of the Northern Song Dynasty was salt water.

Under such a premise, the salt of the Northern Song Dynasty is controlled very high, and the cost of salt is also very different from that of adding taxes, there are benefits, and the benefits are not expensive, there must be someone who wants to take risks, the salt tax is almost related to the foundation of the Northern Song Dynasty, and the eyes of the Northern Song Dynasty have been red in the Northern Song Dynasty on the issue of funds, and the control is extremely strict in this regard.

The arrest of smugglers has never ended, and some of them have even been forced to go up the mountains and fall into the grass.

Zhao Xin is very clear that using the method of drying salt, salt can be obtained very cheaply, and the demand for salt in the Dinghai Navy is not only the salt that more than 1 million people need to eat, but also a very huge number.

At this time, Dinghai himself will dry the salt. It's just that Zhao Xin strictly controlled, although he knew that his salt, as long as it entered the Northern Song Dynasty, he could even provide better salt that could be supplied to the entire Northern Song Dynasty, which could reduce the production cost of salt.

The Northern Song Dynasty, the efficiency brought by industrialization, compared to the soil law of this era, I don't know how much stronger, although the entire Dinghai Navy, only more than 30 kilometers of coastline, on this coastline, because of the port and other things, can not be used much, but under such a premise,

Under such restraint, it is still possible to produce a lot of salt, and the salt price of the entire Dinghai Navy is only one-tenth of the ordinary salt price, which is actually lower than the production cost of the Northern Song Dynasty.

Dingjun used not the coarse salt of the Northern Song Dynasty, the salt of the Northern Song Dynasty, and the sea salt, most of them used the method of boiling salt, which would contain large residues, and even some insoluble things would remain.

For them, the Northern Song Dynasty did not have a good way to deal with them, so they could only eat like this.

However, in Dinghaijun, after the salt drying is completed first, the salt is reintegrated into the water, through filtration, transpiration, and after processing again, what is obtained is the same snow-white salt as the green salt of Western Xia, and the cleanliness and beauty must be on the next level.

With ordinary salt, the method of cooking salt with firewood, Dinghai is centralized and large-scale, salt field salt has paid a certain labor cost, and then boiled salt, using not ordinary small stoves, but large boilers, for the utilization rate of energy, it is much higher, even if it is an extra step, and the process of boiling salt again, but the cost is still very low.

Under such a premise, the navy can afford to pickle sea fish, and there can even be a large waste.

According to experiments and calculations, a fishing boat needs about 100 people, of which there are about 40 sailors, and the rest are fishermen, of which there are about 30 people who are responsible for handling trawls, and more than 20 people, who are selected to be women, who are in the cabin and are used to handle marine fish.

The fish caught are simply processed, the head and internal organs are removed, and then salted with salt, about 10 catties of fish with about half a catty of salt.

This designed fishing vessel can hold up to 400 tons of fish, that is, almost 20 tons of salt.

If you buy it according to the price of the Northern Song Dynasty, this salt will be expensive, but fortunately, the cost of 20 tons is not very high, about 2 Wen per catty, not the super high price of 45 Wen per catty in the Northern Song Dynasty.

Personnel have been recruited, and a series of training sessions have been carried out on the corresponding ships, mainly in the use of trawls.

Before the new boat is launched, two small boats will be slightly modified according to the proportions, and the experiment will be carried out, how to place the trawl, how to recycle, how to fish, all of them.

It's a simple thing, it's mainly a lot of force, through a certain amount of machinery, to put the net down and pull it up.

The launch of the new ship means that the entire fishing operation has begun, and the personnel of the three ships have already been in place, and today, they will enter the ocean and conduct actual combat drills in the surrounding area.

Huge sailboats, one by one into the aqueduct, and then into the canal, although the canal is wide, but not as good as the ocean, the ship is hung a third of the sails, under the action of the wind, slowly accelerated, it took about an hour, finally into the ocean.

The sailboats are all skilled, and Zhao Xin specially transferred them from other experimental ships, and the boats they control are quite flexible, and those fishermen, they are also nervously standing on the deck, today, they will travel thirty or forty nautical miles, about 2 hours, looking for fish, and making some fishing attempts, probably in the evening, will return.

This process, about a week or so, to train and find problems, once the entire ship, are skilled, will really go to the ocean operations, then the efficiency, must be higher than now, similar to now, most of the day is on the road, fishing time is not long.
