I have a sea in ancient times

Chapter 233 What should come, will come eventually
Lu Hai has no hope for the last two kilometers. I hope to get another Dazhanghong, or a Dajuncao.

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

Let them hunt some ferocious beasts. Wild boars can weigh more than 50 catties. There must be some muntjacs, deer, and monitor lizards.

"Hey hey."

The few primitive people pulling the rope suddenly yelled, and then pulled the rope desperately, and the whole rope collapsed very tight.

Lu Hai went to the stern of the boat and saw a black fish struggling through the blue water. The whole body of the fish was round, just like a shell.

Lu Hai's face was full of smiles.

I really didn't expect it.

I thought it was not so easy for me to catch this fish, but it seems that there are some things, the more impossible you think, the higher the probability of them appearing.

What should come will always come.

When fishing tuna, the sooner you can drag it onto the boat, the higher the quality of the fish will be, otherwise the lactic acid will accumulate in the fish and the quality will drop.

Lu Hai asked the primitive people to work harder.

The fish stuck to the back of the boat and slapped vigorously. Lu Hai hooked the gills of the tuna directly with a hook, and then dragged it up.

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

After being pulled ashore.

The tuna was tossing and jumping very hard. It may be because of its size. This tuna has some triangular spines on its tail and back on the deck, so Lu Hai didn't want to be scratched.

Still that gavel.

Directly aiming at its head with melon seeds, and hitting it with a hammer twice, it became much more honest in an instant.

There are many varieties of tuna.

Lu Hai, who has never had much contact with it and only ate it in a Japanese grocery store, didn't know what kind of tuna it was. When his hand touched the body of the tuna, a hand-painted card popped out.

Bigeye Tuna:
It is a fish belonging to the scombroid family and the tuna genus. It is distributed in tropical and temperate sea areas all over the world. It is an oceanic migratory fish and likes to swim in groups. The maximum length can reach 200 cm and the maximum weight is 120-150 kg.

[Number of captures: 2/50]

[Mission countdown: 4 days, 22:31:01]

It turned out to be this product.

However, there are no eggs, Lu Hai has never heard of big-eyed tuna, but the eyes of this fish are quite big.

There are too many types of tuna. Lu Hai felt that when he returned to the real world, he would look it up. It seemed that as long as it was tuna, it was very valuable. Even the cheapest yellowfin tuna could fetch a lot of money.

This set of longline hooks was originally used to catch tuna, but I did not expect to catch it.

Except this set of longline hooks.

Lao Zheng also sent a set of tools for killing tuna, and he also gave the mallet just now.

Most tuna eat raw fish, so after catching this kind of fish, you have to kill it immediately and bleed it immediately.

It happened that during the time when he was playing catching the sea, he also watched a lot of content related to catching the sea. When he was bored, he also watched a lot of videos about handling tuna.

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

A wooden hammer.

A fish head drill.

A nylon monofilament.

A sharp fish knife.

Lu Hai knocked it unconscious with a mallet. Next, Lu Hai took off the hook of the tuna and found that there was actually a big sea bass in its mouth.

It looks like the sea bass ate the bait and the tuna ate it.

Big fish eat small fish.

This is the trick.

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

The purpose of doing this is to destroy its brain and make it die faster. It seems to be a conscience, but it is a kind of hypocrisy.

The moment you poke it down.

A stream of blood mixed with liquid sprayed out, and the tuna violently twitched and resisted, unable to even run because it was hung upside down.

Then, Lu Hai took out the fish knife and prepared to do the bloodletting. Generally, the bloodletting position is about 5-10 inches below the fin, and he stabbed it on both sides with the knife.

After poking down.

There was another spurt of blood, and the entire deck was instantly stained red.

But even if the tuna's brain is destroyed, the fish will still move around because it still has spinal nerves.

At this time, take a nylon monofilament, something similar to iron wire, and pass it through the brain, piercing the spinal nerves of the fish, and killing it completely.

Generally, the whole tuna treatment process includes: stunning, destruction of the medulla oblongata, destruction of the spinal cord, bloodletting, gill cutting, laparotomy, seawater washing, scrubbing, etc.

After damaging the tuna's spinal nerves, Luhai next, with Monday's help, cut to the tuna's gills.

Then cut a knife on the belly to cut off the visceral tissue, then pull out the fish viscera from the gills, and finally rinse the inner cavity with sea water.

After finishing these, it can be put into ice sea water to refrigerate. If it is an ocean-going operation, if you don’t want to go back in a short time, you will usually take it for quick freezing.

It is not so troublesome to catch it in the sea, at least it is frozen and refrigerated, and the taste will not change much in 24 hours.

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

After all, this step is very critical. If it is not handled properly, the quality of the tuna will be greatly reduced, and the selling price will also be lowered.

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

Because tuna has a high probability of being infected with anisakis, although the infection probability is not as high as that of salmon, it is better to kill as little as possible.

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

Anisakis has a strong penetrating ability. In severe cases, the stomach wall may be penetrated, causing gastric perforation, and even entering the muscle.

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

Moreover, there is no specific drug for the treatment of anisakiasis at present, and fiber gastroscopy can only be used to remove the worm body, and surgery must be performed if necessary.

All in all, it's still scary.

Lu Hai remembered that someone in Xiaqi Island seemed to have suffered from this parasitic disease, and this parasite seemed to be commonly found in seafood, especially hairtail and small cucumber fish.

But it does not mean that it cannot be eaten raw. If you want to eat wild sea fish raw, you can keep the seafood below -20 degrees for 24 hours.

This completely kills the parasites, which at that point will just turn into protein in your mouth.

For high-quality tuna, the quick-freezing technology at -60 degrees is generally used. It is said that this freezing method can keep the freshness of the fish to the greatest extent.

After Lu Hai moved the tuna into the cabin and chilled it, the primitive people became excited again, as if they had caught a big fish again.

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

If there is one, there must be two.

It seems that today is going to make a fortune.
