This image is already very obvious, it is a rare huge fish, and it is also a catfish, the color of its back is not black when it is seen from a distance, but gray, judging by its exposed body shape, the whole big catfish is seven or eight meters long.

It was also the first time for Han Du to see such a huge catfish, and he felt that this should not be a catfish species in our country, but like some giant catfish abroad, which should belong to an invasive species.

In fact, this is the European giant catfish, also known as the six-whiskered catfish, which has a lifespan of up to 80 years, and the common body size is generally less than five meters, and this European giant catfish that grew up in our country broke this record in one fell swoop.

The European giant catfish is found all over the large lakes and rivers of Europe, and is a seasoned predator, first paddling its pectoral fins to create a whirlpool to disorient the prey, and then opening its huge and incomparably wide mouth, like a vacuum cleaner to suck the prey into its mouth, swallow it, and of course, occasionally want to suddenly ambush it just now, and eat the target in one bite.

In addition, there have long been terrible legends of European giant catfish eating people, dating back to the 15th century, when some European giant catfish were caught in Russia and human remains were found in their stomachs.

Qin Haisheng's wife, Wang Bijun, recognized at a glance that this was the European giant catfish, she worked at a hydrobiology research institute, and this time she suspected that the water monster was some kind of giant fish, and it was estimated that it was some kind of invasive species, and now it has been confirmed that her guess is right.

However, Han Du didn't have time to ask the two people around him what kind of catfish species this was, because when it ate the bait and rushed out of the water, it happened to be in the trap ring, Han Du took the opportunity to pull up the rope next to it, causing the ring to shrink rapidly, just stuck in its pectoral fin, and its waist was already bound by the rope.

For the sake of insurance, Han Du planned to continue to turn on the battery and let it taste the taste of electric shock, but Qin Haisheng next to him moved faster than him, put on a posture of casting a net, and threw the net out with a shout.

His action in casting the net was standard, and the whole net was spread out in a circle, landing in the middle of the waist of the European giant catfish, entangled its pectoral fins and tail.

Qin Haisheng This is simply a divine assist, Han Du was overjoyed, but immediately after, the giant catfish's body swayed and struggled, and Qin Haisheng was terrible, because he was negligent for a while, and habitually put the long rope of the net on his wrist before posing to cast the fishing net, and now he was unable to support anything, and was pulled into the water by the giant catfish.

With a pop, Qin Haisheng fell into the water, because the giant catfish had been struggling, he also brought him to the catfish, his body was floating and sinking in the water, and he was attacked by the giant catfish from time to time, if he hadn't swam hard and grabbed the thick rope that bound the giant catfish, this made him have a relatively safe distance from the giant catfish.

Facing Qin Haisheng falling into the water, the electric shock trick could not be used, and Wang Bijun next to him was worried that her husband would follow in her son's footsteps, so she cried and cried, and was about to jump into the water, but was pulled by Han Du.

"Don't be impulsive, what if you jump down and encounter danger?"

"I can't control it, I can't watch my wife die in the mouth of this European giant catfish......" Wang Bijun's voice was hoarse, and a certain begging look flashed in her eyes, naturally hoping that Han Du, a young man, could go down to save her husband, but it was dangerous to go into the water, and she had no reason to ask Han Du to do so.

Han Du is also a delicate person, he has already noticed the meaning in her eyes, and now he can't think much about it, his life is at stake, so he helped Wang Bijun take a step back, and then picked up the pot of liquid that anesthetized the fish on the ground and pinched it open.

Unexpectedly, Wang Bijun rushed over and grabbed Han Du's hand and stopped: "No, the medicinal power of this anesthetic is very strong, my wife is not in good health, I am worried that he will not be able to stand this medicinal power." ”

Han Du looked at the giant catfish and Qin Haisheng who were struggling underwater, and his heart was much more decisive than that of a woman like Wang Bijun, and he was not too ruthless, so he pushed her away and directly sprinkled the anesthetic medicine into the waters where the giant catfish was.

Soon, the liquid spread, and a pungent smell wafted out, first of all, a large number of small fish floated up from the water, all with white bellies.

The giant catfish also seemed to be affected by the medicinal liquid, and its movements slowed down a bit, as for Qin Haisheng, he was already a little dizzy, but Han Du was sure that he would not be unbearable, because the anesthetic itself could not even poison the fish.

But with a sudden snap, the giant catfish realized that these medicinal liquids were harmful to itself, and rushed forward with all its might, and the thick rope tied to the iron pillar on the deck was forcibly broken by it, and it took Qin Haisheng to rush to the waters in front of it, and suddenly avoided the area where the anesthetic was dense.

Han Du's eyes were quick, and he grabbed the broken rope and tried his best to prevent the giant catfish from running away, otherwise not only would he not be able to catch the giant catfish, but even Qin Haisheng would be in danger.

However, Han Du's personal strength was really limited, and he was pulled by the giant catfish at the other end of the thick rope and hit the side of the boat, and at the critical moment, Han Du suddenly found a short figure flashing behind him, and then someone pulled the thick rope with him from the side.
