(The last chapter is written about 10 square kilometers, and I accidentally wrote an extra 10,000 words, which has been revised.) Pen, Fun, Pavilion www.biquge.info)

In addition, the cost of building a fishing ground is also very costly.

The most important thing is to prevent the fish from leaving the fishing grounds, and the second is the conservation and other problems in the fishing grounds.

But the Minamino Shuichi Fishery is different, it is completely natural. The input cost is low, and only a variety of seafood fry need to be continuously invested.

"It's a pity that the current North Bay Fishing Ground is 10 square kilometers big, but it's still a little small for me. If only my fishing grounds could be bigger. "Minamino Shuichi can YY his future super fishery with an annual output of 10,000 tons of seafood, I don't know what it will be?

When the time comes, not only will you make a lot of money, but you will definitely become a world-class seafood supplier!

At that time, all kinds of news and magazines will rush to report: Hokkaido's master, Shuichi Minamino, the world's No. 1 marine aquaculture tycoon......

"Ahem...... "Ahem" Minamino Shuyi pulled back his thoughts after a little YY, and the above YY was still relatively far away for him.

"The golden period of distant-water fishing in the world was around the 60s to the late 70s. During this period of time, I will not only make distant-water fishing the world's first, but also make marine fishery aquaculture the world's first in advance. ”

"However, if the fishery farming continues to develop, we really need to cultivate it ourselves. It is not known whether future upgrades of the system will continue to upgrade the capacity of the fishery in this regard. If the system no longer gives the ability related to the fishery in the future, then I will need artificial breeding to build a second fishery in the future, or expand the North Bay fishing ground, and there is no help from the system, which is a bit difficult......" Minamino Shu was melancholy at first.

For example, the artificially cultivated tuna, and now he has the system to support various capabilities, and the North Bay Fishery can certainly easily breed tuna. If, with the development of the North Bay fishery in the future, the area is too small to meet the sustainable development, he will definitely open up new aquaculture fisheries.

At that time, the new fishery will not have the help of various capabilities of the system, and all of them will have to rely on scientific and technological experience and methods to breed, and then not only the cost will be high, but it will be two words whether it will succeed or not.

"Let's hope the system doesn't let me down. "Shuichi Minamino can pray in his heart, because he looked at the experience points of the system a few days ago, and it won't be long before he can level up.

In other words, it won't be long before his system can be upgraded to level 9.

"Minamino, we're going to be fishing once every three months next week. You can take a look at it when you're at home. Inoue said in a coquettish voice. Now Shuichi Minamino is busy, and he can't stay at home like he used to be a lot of time.

"Well, I've been idle for the past two weeks. "Shuichi Minamino would also like to see what his fishing grounds are harvesting.

In the evening, Shuichi Minamino came to the North Bay Fishing Ground alone, and after he switched his vision to inspect his fishing ground, he found that it was really very different from half a year ago. The fish are very dense, and all kinds of fish, seafood, etc. are very fat. It seems that the fishery has several major functions to serve these fish well.

Speaking of which, he hadn't come to see the fishery for half a year. The main thing is that the fishery has little to no management, just the fry are released.

As for the fishing, the trafficking is managed by Ami Inoue.

"Hey, there are so many tuna!" After not looking at it for half a year, Shuichi Minamino just made an inspection and saw that there were a lot of tuna in the North Bay fishing grounds. When you calculate it, it is estimated that there are tens of thousands.

Tens of thousands of pieces have reached a relatively large amount!

"It seems that this time the tuna was successfully farmed. I just don't know what the meat will be like. "Shuichi Minamino knew that tuna farming in his fishery would not be a problem.

But the reason why tuna is delicious is that it swims at a high speed all the time, so the meat is very delicious.

Shuichi Minamino didn't observe every day, and he didn't know if the tuna in his fishing ground were still swimming vigorously every day. But 10 square kilometers is still quite large, enough for these tuna to swim.

"You'll know when you've eaten it. ”

A few years ago, the fishery started with only a few dozen tuna, and later hundreds, thousands. So far, it has reached tens of thousands. Of course, tens of thousands of tuna are fractional species, not just one type.

It is estimated that it is difficult for others to breed tuna, but Lao Tzu breeds tuna simply, which is cool.

In later generations, there were three types of tuna farming.

The first is short-term stocking.

Short-term storage refers to the method of catching 20-60 kg of wild small tuna, and after 6~7 months of feeding, the tuna can grow up quickly. This method of cultivation originated after 1991.

The second definition is aquaculture, which refers to the whole growth stage of breeding with 100~500 grams of wild tuna fry or eggs for 2~3 years of culture. This is mainly for Pacific blue spear farming.

The third is that all of them belong to artificial breeding, and this method of all artificial breeding has been studied and practiced since 1970 and was only successful in 2002.

In later generations, there were breeding projects for blue flag tuna in island countries and other countries, and many of them seemed to have ended in failure, and island countries were raising tuna, but the taste of farmed tuna was not very good, and it was close to the taste of longfin fin, which was inferior to the species in tuna. Tuna is generally at a depth of 200 meters, so farming is difficult.

Farming tuna first has to be deep, and the second fishery is big enough!

In later generations, many artificial breeding sites were relatively small, like the size of a fish pond. The tuna farmed in this way will definitely not taste good. Because they don't have enough swimming grounds.

A week passed quickly, and it was the tri-monthly fishing day at the North Bay Fishery.

Early in the morning, Inoue Ami transferred more than a dozen fishing boats from the root fishing port. These fishing boats belong to the Shuichi Minamino Fishing Company. The tonnage of these fishing boats is not large, they are all more than 100 or 200 tonnage.

Because fishing in the North Bay fishing grounds, you don't need a guy with a lot of tonnage at all.

"President, long time no see!"

At the small wharf of the North Bay Fishing Ground, Tanimura Ueno and a few other people were very happy to see the boss who they hadn't seen for a long time.

Ishida Yu, Tanimura Ueno and others are all there, but the old man Kimura is not there, and he seems to be fishing at sea now.

As for these two goods, they just came back from fishing to rest, so they were called over to help.

"Long time no see. Minamino said with a smile. The people who followed him at the beginning are now basically his henchmen. However, they did not disappoint Shuichi Minamino, who has done well in the past few years.
