The fish in the sea are generally relatively large, and most of the fish caught by everyone are more than four or five catties, except for the giant moray eel before Zhou Xiaolin, and there are many more than ten catties, which makes everyone addicted.

At this moment, Wang Biao suddenly shouted, and his money line was pulled out violently, and even his sea rod was pulled out. And he was holding the rod tightly, and with a sharp pull, his body threw himself out, hit the side of the ship, and almost capsized into the sea.

"Help, hook the big guy again." Zhang Zhide and Zhou Xiaolin pounced at the same time to help Wang Biao stabilize the sea rod, but the huge force made them also kick forward a few steps, and hurriedly beckoned others to come over to help.

Cai Xingming, Wang Hongzheng, and Wang Tiezhu were next to them, and they hurriedly threw their sea rods and pounced, but they still couldn't hold it, and even everyone felt that the entire Golden Pearl was moving forward.

"Control room, probe it now, prepare to launch the Harpoon." Lin Fan knew as soon as he saw that Wang Biao must have caught this fish, so he hurriedly ordered the engineering soldiers in the control room, and at the same time ordered the nearby aircraft to immediately approach this side to prevent accidents.

At this moment, the sea water in the distance churned violently, and a black spinnaker-shaped dorsal fin suddenly appeared on the sea, which surprised everyone, and Chen Chaoguo exclaimed even loudly: "Oh my God, that's a shark." Let it go, it's a shark, and if you anger it, you won't even be able to keep the fishing boat. ”

With his shout, there was a sudden loud bang on the sea, and a behemoth jumped out of the sea in an instant, with a body length of several meters, a dark body, a spiked dorsal fin, and a triangular flat tooth in the open giant mouth, and the image was very hideous.

"It's a horn shark. Let's let go together, and the sea rod is gone. Zhang Zhide recognized it at a glance, and immediately beckoned everyone to let go, only Wang Biao was a little reluctant, this was the big fish he caught.

However, what people didn't expect was that after everyone let go of the sea rod, the sea rod was pulled down into the sea by the horn shark. However, the horned shark did not leave there, and seemed a little annoyed, and turned and rushed towards the Golden Pearl.

"Oh no, this shark has a grudge against us, get out of here." Chen Chaoguo was so frightened that he shouted loudly.

"Don't panic, fire the harpoon, hurt it, maybe it will leave." Lin Fan snorted, and in an instant, two harpoons flew towards the horn shark, both of which were deeply inserted into the horn shark's body.

"Wow-"

Under the pain, the horn shark's body rose violently in the seawater, setting off waves one or two meters high, and the sea was instantly stained red with blood, so that everyone did not dare to wait on the side of the boat.

"Get out of here, get out of here, don't alarm it." After Lin Fan gave the order, the engineering soldiers immediately drove the fishing boat and slowly left.

However, after only a kilometer or two away, suddenly the surrounding sea surface churned, and everyone was shocked, because in the moonlight, several black triangular dorsal fins suddenly appeared on the surrounding sea surface.

"Oh my God, how can there be so many sharks?"

Lin Fan looked around, and there were seven or eight horn sharks around the injured horn shark, and they seemed to be fighting something, stirring up violent waves, sometimes rushing out of the sea, sometimes sinking into the sea.

"Whoosh-"

Suddenly, a black shadow burst out of the sea, and its huge body glided several meters above the surface of the sea like a kite, and then rushed towards a horn shark, wrestling with it.

"It was a group of flat sharks, which were natural predators of horn sharks." After Zhang Zhide saw it, he immediately breathed a sigh of relief and said to everyone.

The flat shark has a flat body, broad pectoral and anal fins, a very large head and body, small eyes located on the back, and a pair of large blowholes behind it. There is a pair of tentacles in front of the nostrils. The head is flanked by a row of skin folds and triangular fins. The teeth are small and sharp, and the shape of the teeth in the upper and lower jaws is similar.

The flat shark is gray to reddish or greenish-brown on the back with small black-white dots and a white ventral surface. Juveniles are more ornamented than adults, with pale lines and dark bumps. The anterior edge of the dorsal fin is darker, the posterior margin is lighter, and some have white spots on the neck.

Flat sharks are usually inactive, and they lurk at the bottom of the sea to catch food, dressed in colors similar to their environment. But once frightened, it can "fly" and "glide" with the help of its wide pectoral fins, especially the "start" speed is very amazing.

Flat sharks are nocturnal and will hide themselves in sediments to ambush their prey. They mainly eat benthic rays and invertebrates, and flat sharks are the ones they like to hunt.

After listening to Uncle De's account of the horn shark and the flat shark, they all breathed a sigh of relief, no longer worried that the horn shark hated them, and slowly left while observing this rare shark battle from a distance.

Although it is difficult to see clearly from a distance, the waves of the sea are rolling and turbulent, stirring up a huge sound, even if it is far away, it is thrilling and shocked by the wonder of nature.

The fishing boat slowly departed, and then moved away from the surrounding waters. And after this incident, everyone's interest in sea fishing has also faded a lot. Only Wang Biao still remembered that the biggest fish he caught was the biggest one, but unfortunately he couldn't catch it and bring it back.

"Alas, it's good to take a few photos if you know it earlier, and let people know it if you spread it to WeChat and Moments." Suddenly, Wang Biao patted his head and said with remorse.

"Forget it, Biaozi, there will be a chance in the future, maybe you can catch a bigger guy." Lin Fan comforted him and said.

"Whew-"

Just when Lin Fan's words were not finished, there was a sudden sound on the ground, which was the sound of the fishing line being pulled quickly. Everyone looked over, but Lin Fan's sea rod had not yet been put away, and the fishing line was being pulled out quickly.

"Stop the boat, stop the boat, take a look at what's it, it's definitely a big guy too." Zhang Zhide hurriedly shouted.

"It can't be a shark again, right?" Chen Chaoguo muttered beside him, and at the same time retreated again and again.

"It's not that coincidental, just pull it up and see." Lin Fan didn't panic, he grabbed the sea rod in the past, and as soon as he pulled it, he found that a huge force was coming, and he immediately caught a big guy.

"Don't panic, wait for it to drag the fishing line first, then slowly reel in the line and play with it." Zhang Zhide hurriedly came over to help, and the others had already collected the rods, and they all ran over, ready to help.

Sure enough, when the 100-meter-long line was about to be pulled, the pulling force suddenly became smaller. Lin Fan immediately began to reel in the line, and the electric coil runner immediately turned whirring, quickly retracting the fishing line for dozens of meters, and the pull force appeared again.

Lin Fan was not in a hurry, he slowly followed it, sometimes releasing the line, sometimes rewinding the line, and even letting the fishing boat follow it, after more than 20 minutes, it was finally dragged to a close place, and then used the fishing net to quickly fish it up, and a big fish two or three meters long appeared in the eyes of everyone.

Everyone looked at it, and saw that this big fish was long, thick and round, streamlined, tapering backwards, and the tail base was slender, and the tail fin was forked or crescent-shaped. There are distinct ridges on both sides of the caudal peduncle, and a row of small fins behind the dorsal anal fins. It has a torpedo body shape, its cross-section is slightly rounded.

The underside of the body and the ventral surface of the fish are silvery-white with colorless and columns of colorless dots, the first dorsal fin is yellow or blue, the second is reddish-brown, the anal fin and distal fin are dark yellow and have black edges, and the central caudal keel ridge is black.

"Oh my God, this, this, is this tuna?" Uncle De suddenly shouted, and everyone was shocked when they heard it, because except for Wang Biao, no one knew the price of tuna.

"I'm afraid it's not just any tuna, it's a bit like bluefin tuna." Zhou Xiaolin's voice trembled a little.

"What's wrong with the tuna? What happened to bluefin tuna? Isn't it remarkable? Wang Biao asked with some disdain.

"The amount of tuna caught in the world every year is very limited, ordinary tuna is basically about three or four hundred pounds, and bluefin tuna is more expensive than gold. On July 13 last year, five university girls picked up a prized bluefin tuna off the coast of Cornwall, England. This tuna weighs about 272 catties in two meters, and has a market value of nearly 7 million Chinese dollars. Zhou Xiaolin said lightly.

"What? Is bluefin tuna so expensive? Is this really bluefin tuna? I think it looks like two or three meters, and I'm afraid it also has two or three hundred pounds. Wang Biao almost drooled after hearing this, because if the fish Lin Fan caught was really a bluefin tuna, it would probably be worth millions.

"I'll let my dad see it first, he's seen real bluefin tuna, and he shouldn't be mistaken." Zhou Xiaolin said, passing the photo of the fish to his father, and it was taken from different sides.

Lin Fan also took a deep breath at this time, with a happy smile on his face, he had already asked the engineering soldiers to check and confirm that this fish was tuna, and it was the expensive bluefin tuna among the tuna.

The tuna has a streamlined shape, and the cuirass that extends along the head is like a unique balance board that adjusts the current. The tuna's tail is half-moon-shaped, allowing it to dash forward quickly in the sea.

The tuna has strong muscles and a crescent-shaped tail fin, a breastplate with gradually enlarged scales on the shoulders, a dark dorsal side, a silvery white ventral side, and often iridescent glows and stripes. Another feature is the well-developed network of blood vessels under the belly, which can be used as a thermoregulatory device for long-distance slow swimming.

Tuna with greater economic value includes 6 species, including bluefin tuna, mosu tuna, bigeye tuna, yellowfin tuna, albacore tuna, bonito, etc., among which bluefin tuna, masu tuna, bigeye tuna, yellowfin tuna are raw materials for sashimi, and albacore tuna and bonito are mainly used as raw materials for canned tuna. >
