Lu Hai has no hope for the last two kilometers. I hope I can have another big Zhanghong, or a big army.

If you really can't catch big fish, Lu Hai thought it would be better to open some land maps and give the primitive people more weapons for hunting.

Let them hunt some beasts, any wild boar can exceed 50 kilograms, and some deer must have some deer, and there are also such giant lizards.

"Hey hey."

The primitive people who were pulling the rope suddenly started shouting, and then pulled the rope desperately, and the whole rope collapsed very tightly.

Lu Hai walked to the stern and looked at it. Through the blue sea, you could vaguely see a black fish struggling, and the whole fish body was round, just like a cannonball.

Lu Hai's face was full of smiles.

I really didn't expect it.

I originally thought I wouldn't catch this fish so easily, but it seems that some things are more likely to appear, the more likely you will appear.

What should come will always come.

When fishing for tuna, the faster you drag it onto the boat, the higher the quality of the fish, otherwise the lactic acid accumulates in the fish and the quality will decrease.

Lu Hai made the primitive man work harder.

The fish stuck behind the hull and slapped it hard. Lu Hai directly hooked the tuna gill with a fish hook, and then dragged it up.

This tuna is very large, but it will be a little shorter than the previous red fish, but the whole body looks fatter and feels like a round fish.

After being pulled ashore.

The tuna mission is tossing and jumping very well. Perhaps because of its size, this tuna has some triangular thorns on its tail and back on its deck, and Lu Hai does not want to be scratched.

It's still the same mallet.

He hit his head with two hammers and became much more honest in an instant.

There are many varieties of tuna.

I didn't have much contact with him normally. Lu Hai, who had only eaten in Japanese restaurants, didn't know what kind of breed it was. Just when his hand touched the body of the tuna, he jumped out a hand-painted card.

Big Eye Tuna:

It is a fish under the Macadae family, a genus Tuna. It is distributed in tropical and temperate sea areas around the world. It is an oceanic migratory fish that likes to swim in groups. The maximum length can reach 200 cm and the maximum weight is 120-150kg.

【Capture count: 2/50】

【Countdown to mission: 4 days, 22:31:01】

......

It turns out it's this guy.

However, Lu Hai had never heard of big-eyed tuna at all, but the fish's eyes were quite big.

There are too many varieties of tuna. Lu Hai feels that when he returns to the real world, he will check it. It seems that any tuna is very valuable. Even the cheapest yellowfin tuna can be sold for a lot of money.

This set of longline fish hooks was originally used to catch tuna, but I didn't expect to catch them.

In addition to this set of longline fish hooks.

Lao Zheng also gave him a complete set of tools to kill tuna, and he also gave the wooden hammer just now.

Most tuna eat raw fish, so after catching this fish, you have to kill it as soon as possible and bleed it immediately.

It just so happened that during the time he was playing the sea rushing, he also watched a lot of content related to sea rushing. When he was bored, he also watched a lot of videos dealing with tuna.

Tuna tastes delicious, but it is much more than killing pigs. First of all, you need a complete set of tools.

A wooden hammer.

A fish head drill.

A nylon monofilament.

A sharp fish knife.

Lu Hai had knocked it out with a wooden hammer. Next, Lu Hai took off the hook of the tuna and found that there was actually a very large sea bass in its mouth.

Depending on the situation, the sea bass should have eaten the bait, and the tuna swallowed it again.

Big fish eat small fish.

This is what happened.

Lu Hai hung the tuna upside down with a hemp rope, then touched the soft position of his forehead with his hands, took out the fish head drill, poked it directly in, and stirred it several times.

This is done to destroy his brain and make him die faster, a seemingly conscience but a hypocritical approach.

The moment it poked.

A stream of blood mixed with liquid ejected out, and the tuna twitched violently and resisted. Because it was hung upside down, it could not even run away.

Then, Lu Hai took out the fish knife and prepared to bleed. The general location of bleeding is about 5 to 10 below the fish fins, and stabbed each side with a knife.

After stabbing it.

The blood sprayed again, and the entire deck was dyed red in an instant.

But even if the tuna brain is damaged, the fish will still move randomly because it has spinal nerves.

At this time, you have to take a nylon monofilament, something that looks very similar to iron wire, pass through the brain, pierce the fish's spinal nerves, and completely kill it.

Generally, the entire treatment process of tuna includes: stunning, brain medulla obstruction, spinal cord destruction, bloodletting, gill cutting, caesarean section, sea water rinsing, scrubbing, etc.

After destroying the spinal nerves of the tuna, Lu Hai then cut the gills of the tuna with the help of Monday.

Then cut the stomach and cut off the internal organs, then pull out the internal organs of the fish from the gills, and finally rinse the internal cavity with sea water.

After doing this, you can put it in the ice water and refrigerate it. If it is an ocean-going operation and you don’t want to go back in a short period of time, you will usually use it to quickly freeze it.

It doesn’t have that much trouble to catch it near the sea. At least it depends on freezing and refrigeration, and there will be no big taste changes in 24 hours.

The process of killing tuna is indeed a bit cumbersome. At present, Lu Hai almost has to operate it alone, so I dare not teach it to other primitive people.

After all, this step is very critical. If it is not handled well, the quality of tuna will drop greatly and the price for sale will also become lower.

Tuna meat is indeed delicious, but it is generally not recommended to catch it from the sea, so it is eaten raw.

Because tuna has a high probability of infection with alienopsis nematodes, although the probability of infection is not as high as salmon, it is better to try to die as little as possible.

A country that likes to eat raw fish often suffers from this parasitic disease, which is said to make you worse than death.

Alitos nematodes have strong permeability. In severe cases, the stomach wall may be penetrated, causing gastric perforation and even entering the muscles.

Generally, after eating fish, the disease occurs 1 to 5 days, showing gastrointestinal symptoms such as nausea and vomiting, severe abdominal pain, and intestinal obstruction, intestinal perforation and peritonitis.

Moreover, there is currently no special treatment for alizoidal nematode disease, so you can only use fiber gastroscopy and remove the insect body. If necessary, surgical treatment is required.

Anyway, it's still very scary.

Lu Hai remembers that someone on Xiaqi Island seems to have suffered from this parasite disease, and this parasite seems to be common in seafood, especially hairtail and cucumber croaker.

But it doesn’t mean that you can’t eat raw. If you want to eat wild sea fish raw, you can keep the seafood below -20 degrees for 24 hours.

This will completely kill the parasites, and then these parasites will only become proteins in your mouth.

High-quality tuna generally uses -60-degree quick freezing technology. It is said that this freezing method can maximize the fresh taste of the fish.

After Lu Hai moved the tuna to the cabin and cooled it down, the primitive people became excited again, as if they had pulled the big fish again.

Lu Hai almost guessed that this kind of fish never acts alone.

There must be two.

It seems that I will get rich today.
Chapter completed!
