The distance was closer, and Zhou Sheng also saw the seabirds circling the sea.

The fan-shaped fish scout at the bow of the boat shows a large school of fish underwater.

When Zhou Sheng saw it, he jerked the skin of his head a few times: "If the purse seine boat is comfortable, why not a purse seine boat." ”

"Be beeped, slow down." Chen Yuandao.

Zhou Sheng quickly slowed down, adjusted to the twin-engine economy cruise mode, and drove the fishing boat over.

The fishing boat observes on the periphery of the fish, during which the vertical probe is also opened, which is a school of white fish.

It is a hot group fish that can be found in tropical waters all over the world and is very cheap. This kind of fish does not seem to exist in China, mainly in the equatorial seas, it should be a kind of golden barracuda family, which looks somewhat similar to the barracuda, and has silver-white stripes on its body.

This white fish has no teeth and is not very large. The larger white fish is only three or four catties, and the more common white fish weighs less than 1 catty.

White fish are very common, with a school of tens of thousands.

The school of white fish seen now is very large, and there are bonito around the outside of the school of white fish, and behind the bonito are sharks, tuna, etc.

A person who specializes in finding fish can calculate the number of fish in an area of water. This calculation method Chen Yuan will also ......

Moreover, the fish swarm algorithm can be used to artificially gather fish.

Fish tend to find places with more nutrients on their own or following other fish, so the place where the fish survive the most is generally the place where the nutrients are most abundant in the water.

This is the sea where two major currents meet, and there are more nutrients, and there is a high probability of gathering fish without external interference.

There are some typical behaviors of fish more.

1. Foraging behavior: Under normal circumstances, fish swim randomly and freely in the water, and when they find food, they will swim quickly in the direction of gradually increasing food.

2. Gathering behavior: In order to ensure their own survival and avoid hazards in the process of swimming, fish will naturally gather into a group, and there are three rules to abide by when fish gather: separation rules: try to avoid overcrowding with neighboring partners; Alignment rules: try to align with the average direction of neighboring partners; Cohesion rule: Move as far as possible towards the center of the partner.

3. Tail-chasing behavior: When one or several fish in a school of fish find food, their neighboring partners will follow them to the food point quickly.

4. Random behavior: Individual fish usually swim randomly in the water, which is to find food spots or companions around them on a larger scale.

So for some common schools of fish, there are very few, very few fish of a single species.

When a group of fish of one species gathers, it is easy to attract other fish.

There are too many fish here, and Chen Yuan calculates the approximate number of tuna through the vertical fish detection screen.

Knowing the size of the fish, then observing the vertical fish detection screen, recording the number of tuna, the total number of tuna appears at a certain time, and the approximate number of tuna can be judged by comparing the area of the fish school.

The tuna reminds the big, as well as his size, it is still very easy to judge whether it is tuna or not.

After observing the periphery of the fish for more than ten minutes, Zhou Sheng asked, "What's the matter?" ”

Chen Yuan lit a cigarette, looked at his notebook, and took a deep puff of cigarette: "A lot." ”

"How much is a lot?"

"A lot is a lot." Chen Yuan took a deep breath: "I feel that all the tuna within a radius of dozens of nautical circles are coming." But it's not easy to ......."

There are really a lot of tuna here, and just now, a school of tuna appeared on the vertical fish scout.

Tuna also move in groups, even when hunting. This is a school of fish wrapped in fish......

Inside are white fish, outside some are bonito, after that there are wolffish, sharks, tuna, and so on.

Chen Yuan: On the first day they came to Gilbert to fish, they encountered two schools of fish. The first is a school of bonito, and the school of tailfish is tuna. The second is also a school of bonito, and when the school of fish is found, it is a school of vegetarian fish......

Let's not talk about the first school of fish.

The second group also caught some tuna when it was hooked.

Now this school of fish is complex.

The mixed school of bonito and tuna is easy to catch, and the skipjack tuna swims fast. Tuna is not particularly easy to hunt for bonito. At that time, it was easy to catch tuna when you took the bait.

But here, this school of fish is bigger. In addition, the bonito has also completed the encirclement of the white fish......

The Big Fish and Takaga are 97 nautical miles away. Now it's too late to catch the bait. And even if you take the bait, the probability of hitting the tuna should not be particularly high.

Chen Yuan turned on the wireless phone: "Hey, Master." ”

"Yes."

"We found a large school of tuna, at least a thousand tuna, dominated by yellowfin tuna." Chen Yuandao.

"We'll be right here." Gao He slammed the table excitedly and shouted, "How big is the tuna?" ”

"It's basically adult tuna." Chen Yuan said: "However, the tuna here has already begun to hunt. ”

Lin Xinhai's scalp is numb now: "There are really thousands of tails? ”

"Just more, not less. There is a certain probability of more than 2,000 tails. Chen Yuan took a deep breath, the fish gathered, and the air was filled with an enticing fishy smell.

This fishy smell is not the smell of the fish stalls in the summer vegetable market, but the smell of golden guns. Pure banknote taste.

"We'll come over ...... now," Mr. Lin said.

"It's hard to catch this fish, you have to have a purse seine." Chen Yuan said.

"There are no purse seine boats." Takaga said.

Thousands of tuna, and most of them are adult yellowfin tuna, which is worth at least tens of millions of bases.

Chen Yuan said 'um', he wanted to contact Luo Hao to ask if there was a purse seine boat nearby...... But when I think of the Dongjiang fishing industry, there are only three purse seine boats operating here, and they are all in the north.

Chen Yuan knew where the three purse seine boats of the Dongjiang fishery were, and there was no need to contact them at all.

"Don't worry, come back when you collect the rope." Chen Yuan said.

"What kind of fish is the tuna surrounding you?" Takaga asked.

"It's a mixed school of fish. The innermost part is small fish such as white fish and sardines, and the outside is bonito, tuna, and so on. Chen Yuan said: "The hunt has already begun." ”

There are fish jumping on the surface of the sea, not one or two, but many fish jumping out of the sea......

The seabirds on the surface of the sea have already reported a meal.

Some seabirds flew onto their fishing boats, while others flew towards the nearest island......

The seabirds dispersed, and the scene of large predation began to be staged.

Chen Yuan and the others stayed away from the fish, and observed with a fan-shaped fish probe, the fish were chaotic, and the small fish in the central area began to escape, and the big fish pursued them......

"Alas~!"

Zhou Sheng held his head in his hands, in pain.

Chen Yuan also rubbed his cheeks vigorously, such a school of fish was born to exist for purse seine boats. It's a pity.

If this purse seine boat comes over and goes down the net, then it will be 'rich'.
