Before the plan started, Zhang San still had to go to Sea Shark Island to have a look, and then he had to give lessons to the orphans here, and then establish a branch of the Way of Chivalry, these orphans Zhang San had to brand themselves for them, but he still had to go to Sea Shark Island to see.

After arranging the things here, Zhang San took Zhang Yuanba on the cargo ship to Sea Shark Island, the cargo ship set off at night and sailed until the next morning, Zhang San was about to go to the outside of the cabin secretly, only to see a panicked running and shouting outside: "Turn the rudder quickly!" Whale! Whale! ”

Zhang San hurriedly went out to watch and saw a large column of water on the sea a few hundred meters away, and suddenly a gray figure suddenly came out of the sea, and then smashed heavily into the seawater, splashing a large amount of seawater, and the boat exclaimed.

At this time, Zhang Yuanba also ran out of the cabin and came to the bow of the boat, licked his lips when he saw this scene, and asked, "Third brother, how many meals do you say you can eat when you catch this fish?" ”

Zhang San said with a smile: "You know how to eat, this whale has at least 20,000 catties or more, how much can you eat in one meal?" ”

Zhang Yuanba counted with his fingers for a long time, and finally shook his head and said, "Anyway, we can eat a lot of meals, why don't we grab one and taste it, third brother?" ”

Zhang San asked, "How to catch it?" Are you going to go into the water to catch it? ”

Zhang Yuanba shook his head, and said with a sincere smile: "I don't have that ability, why don't I tie a hammer to a stone and hit him?" ”

Zhang San looked at the boat and shook his head and said: "Forget it, our ship is carrying too much cargo, and there is no place to put it when the draft is recaptured, forget it, let's get some fishing boats to catch it in the future." And if you smash him and can't kill him, he dives to the bottom of the water, won't you be blind? ”

Zhang Yuanba nodded when he heard this, looking at the whales with a regretful expression, Zhang San looked at the whales and remembered the marine fishing industry, and secretly scolded that he was really a pig's brain, he didn't find out about such a big treasure in the ocean, and he really guarded the gold mountain to ask for food.

A single whaling industry a whale is less than 20,000 catties, more than 100,000 catties, and a whale is tens of thousands of catties of whale oil and tens of thousands of catties of meat, whale oil is a kind of high-grade oil, used as lamp oil is not only high brightness and burn-resistant, but also smokeless, and whale oil can also be used to make soap.

A pound of good lamp oil can be sold for at least 400 yuan, if a whale can produce 40,000 pounds of oil, then it can be sold for 16 million yuan, and this alone can be sold for 20,000 yuan, not to mention that a pound of oil can be made into four pieces of soap with whale oil, such a good soap is not expensive to sell for 400 yuan, right? In this way, the price has tripled.

And a lot of whale meat is a good source of meat, as for whale meat is not delicious? If you think about what the Japanese are doing, you will not believe that whale meat is not delicious, but it is whaling under the pressure of public opinion all over the world.

It is said that whale meat tastes like beef, but beef will not taste good? It's just to take a step back, even if it's not delicious, in ancient times when meat was scarce, everyone cared about whether there was food or not, not whether it was delicious or not.

And the liver of whales and all marine fish can be used to make cod liver oil, cod liver oil is a good medicine for night blindness, with cod liver oil Zhang San no longer has to worry about his soldiers have night blindness.

Moreover, whale skin can be used as armor, bones can be used to boil glue, tendons and baleen whale baleen can be used to make bow strings, and even unused offal can be made into feed for chickens, ducks, pigs, and dogs.

Therefore, selling a whale can bring Zhang San at least seventy or eighty thousand yuan, this business is definitely cost-effective, Zhang San is a little impatient to build a whaling ship, this needs to be carefully designed.

There is also trawl fishing, with trawl fishing shallow trawl nets can catch a large number of marine fish, deep trawl nets can catch a large number of bottom shellfish shrimp crabs Although shrimp crabs and shellfish are not worth now, but there may be pearls in the shells, and if you catch coral reefs, it will make a lot of money.

In this era, coral is a real valuable, and the price of one night a year is enough for a boatload of people to eat for a lifetime, so trawling is definitely an artifact of large-scale ocean fishing. After getting it done, Zhang San made a lot of money.

There is also ground cage fishing, ecstasy array and row fishing, these three are important tools for small fishing boats and offshore fishing, and these things can be made so far and near, deep and shallow seas can all be taken into account.

And Zhoushan Island is close to the famous Zhoushan fishing grounds, which is one of the four major fishing grounds in China, and is one of the largest fishing grounds in the world.

In later generations, 10,000 or 20,000 mechanized fishing boats surrounded this place and the fishing efficiency was dozens of times that of now, so it is impossible for Zhang San to catch the fish here without hundreds of thousands of fishing boats, will Zhang San build hundreds of thousands of fishing boats to fish here? Obviously, it won't, and then control the mesh to catch the big and let it go small.

As for whaling, it is also a truth, with Zhang San's current scale, there is almost no big impact on the number of whales, and now commercial whaling has not yet begun, and the number of whales in the world is definitely more than 10 million, Zhang San now let alone catch 10,000 a year, it is estimated that 1,000 is enough to digest.

A thousand whales can bring more than 80 million yuan in profits, not to mention the whole Song Dynasty, even if you add ocean trade, it is enough, and whales are migratory animals, which will run around the world with the ocean currents every year, so Zhang San doesn't have to worry about overfishing at all. 、

What's more, after a few years, Zhang San controls the ocean, so he can only do it himself and not others, so that it will be easier to control the overfishing of whales, and he can control profits.

Zhang San now can't wait to go back to the shipyard to design whaling ships and trawlers, but Zhang San thought for a while and suppressed his impulse, although large-scale fishing activities are hugely profitable, but this requires the support of a whole industry chain.

The market cannot absorb so much seafood by the seaside alone, which requires follow-up processing to keep up, and valuable fish species need to be stored in ice for long-distance transportation. Ordinary fish needs to be processed or salted, dried, or canned.

Pickling fish requires a lot of sea salt, including canning, so Zhang San's current boiling salt is not enough, so Zhang San wants to build a salt farm for drying salt before starting large-scale fishing.

There is also a large trawl, this is a brand new thing, Zhang San has not seen it, but he knows the general principle, so he needs to explore the experiment to weave it, and the same is true for whaling, whale fork whale guns, whaling crossbows, which all need to be modified, and floating barrels also need to be specially made.

And it is best to do a certain amount of pretreatment of the whale on the boat, otherwise the internal organs of the whale are estimated to stink when pulled back to the dock, and the meat is basically inedible.

The advantage of pretreatment is that it increases the time for the whaling ship to stay at sea, and it does not have to wait for one to return to the dock, which in turn puts forward the requirements for the tonnage of the ship, and a whale of 30 to 50 tons, with a boat handling three heads as the upper limit, then it needs to be more than 2,000 stone load.

This kind of ship is very conspicuous, a large number of new ships were built, and in a blink of an eye they ran into the hands of pirates, and no one would believe you if you said that you and pirates did not have a leg, but the number of such ships built will not be less.

Because this kind of boat can not only be used as a whaling ship, a little modification, but also can be used as a trawler, this kind of boat Zhang San has to build at least a few hundred, how to hide it has become a big problem.
