The conditions for the sale of sailing fishing boats by the fishing company are as follows: first, the purchaser must be a national of the country with shaving hair and obtaining a license, and the benefits will definitely only be left to his own people, and foreign capital is not allowed to enter this high-tech field, even if it is the full amount.

When the rare little capitalists in Chengde have scraped together enough down payment, they can board the ship. Fortunately, for these people, it is common for coastal fishermen to buy boats and go to sea to fish together, so everyone has no scruples about being fishy, a stocky man with calluses on his hand, and he will negotiate the matter (love qg) after drinking a drink.

However, the situation after boarding the ship was not optimistic, and now it is equivalent to the shareholders paying a high price to hire the original captain, marine engineer and other technical personnel to work for them.

In this process, shareholders need to take over the ship with their own people as soon as possible. In this way, the high labor cost can be reduced and the loan can be paid off early.

You must know that in order to transfer the precious skilled workers back to do other things as soon as possible, the fishing company has added a "technical tap fee" to these people. If they want to make money, they must quickly master the technology and snatch the profits back from the company.

Yu Chengde is working hard under the gantry crane of the Fathead Fish at the moment, making a stupid black and thick winch net.

To tell the truth, from the moment he saw the ship's gas "ice cellar", he was deeply fascinated by this mysterious power.

Yu Chengde, who has been fishing for half his life, couldn't imagine that there was this kind of (sao sāo) ((cāo) cāo on the fishing boat, although he is a southerner, but he still understands the truth that fish are not easy to rot when the weather is cold.

After that, when he boarded the ship, just like Grandma Liu, the worldview of fishing was subverted, the strange black box where you could talk between the two boats, the glass plate where you could see the fish on the bottom of the sea, the winch that laid the iron net into the sea by itself, and the rumbling iron tools in the engine room

The five shareholders, big and small, together with the twenty or so nephews they brought on the boat, were all numb at this moment, and they were at a loss, not knowing what to do.

So they can only learn from the most basic places step by step.

The nephew was sent to the engine room, and the others learned from the simplest cloth nets

There are two types of cloth nets: purse seine nets and trawl nets.

Purse seine nets are the easiest way to catch shallow fish. The boat casts its net and circles around the fish, and soon there is a spectacular sight of fish leaping on the surface.

Trawling is a bit more complicated.

The trawl of later generations is a very terrifying existence. One or two boats dragged large nets behind them, netting the middle and lower layers of marine life and the environment, completely destroying the seabed ecology, and greatly reducing the coastal fish catches of various countries, and turning to the deep sea one after another.

However, when the environment is damaged, it cannot be repaired. Why do stick countries often arrest rabbit fishermen, because there are no more fish off the coast, the bottom of the sea is full of broken nylon rope nets and lifeless wasteland, and the creatures are scraped away by forklift-like trawls.

The trawlers that appeared in the 17th century had a different style.

In later generations, the thickness of steel plates for ordinary fishing boats was about 2 centimeters. The 17th-century wooden sailing ship was far behind in efficiency at the same tonnage, and in order to achieve the same structural strength, it was necessary to use very thick wood. Normally, this figure is no less than 1015 cm.

You know, the double oak hull of the HMS Victory of the British Royal Navy is a perverted 46 centimeters

Thickness means heaviness and bulkiness. What a 2-centimeter steel plate can do, the fishing boat needs to increase its weight by at least 5 times more to barely meet the requirements.

The bulky structure greatly limits the power and functionality of wooden boats like the Fathead. You must know that the most common 240-ton trawler in later generations has a fish capacity of 983 tons of ice. And what is the fish carrying capacity of the fathead with a displacement of 400 tons, 85 tons.

Yes, the displacement is more than 100 tons, and the payload is down. There are pots with inefficient, high-volume gas-powered systems, pots made of thick lumber from the planks to the beams, and pots with hard sails and cables.

In this situation, the power system, which is already a little inadequate, is a heavy fishing net that can't drag too big a wire fishing net plus the fish inside, not to mention the bottom, and it is troublesome to catch middle fish.

Today is the first time in the 10 days since they boarded the ship in Chengde that they have carried out trawling operations, and before that, they had used simple purse seine nets. As the captain who was watching the instrument in the cabin gave an order through the loudspeaker, Yu Chengde and his group, who were waiting on the deck, hurriedly began to get busy.

Yu Chengde's task today is to start the winch. As the motor-driven winch slowly began to work, the pulley on the gantry crane also began to rotate, and the trawl behind the fathead fish (body shēn) began to be slowly pulled to the stern, and at the same time, the engine room also received an order, and the ship's speed began to decrease.

Twenty minutes later, a large wire net, much smaller than the later trawls, was towed up from the iron slipway at the stern.

Seeing the fish struggling and jumping in the nets, all the sailors pounced at this moment, and the hardest work began.

Yu Chengde and they want to throw the small fish and sharks back into the sea in the shortest possible time. Small fish here are those that are less than 40 centimeters shorter than their elbows.

Over hundreds of millions of years, the ocean's various water layers at different pressures have been populated with fish. Historically, it was not until the 20th century, when humans used nylon on a large scale, that fish in the middle and lower layers of the ocean were actually caught in large quantities.

And in the plane of traversal, thanks to motors and steel wire nets, the mesopelagic fish in the Taiwan Strait have been hunted for the first time in hundreds of millions of years.

Although the mesh of the steel wire mesh has expanded to a situation that later generations of fishermen dare not imagine, there are still many "small fish" trapped in the net, and at this time it is all up to manpower.

Yu Chengde, they not only have to throw out all the small fish, but also deal with the big fish. The quality of the fish that has never been caught in the past is too high, and all kinds of thick sea bream, yellow croaker, and Pacific salmon are stuffed with fishing nets, and deep fish species including tuna are often brought up.

When the fishery resources are too abundant, the fishermen will naturally improve the quality of the products, thereby reducing the cost of sailing.

Large quantities of high-quality pre-treated fish are stacked into the gas cold storage, while the tail of the fishing boat is constantly flowing into the sea with blood, entrails and fish heads. The bloody feast even drew a trail on the surface of the ocean, attracting countless fish and seabirds, so that the heads of the grinning fishermen were covered with bird droppings.
