Structurally speaking, Tianya Island has built a vertical wharf, which is the most common wharf on the outer islands. It is convenient for ships to dock and machinery to be driven directly to the front of the wharf, which can improve loading and unloading efficiency.

For example, in areas with large water level differences in inland rivers or some islands with angular terrain, they will use slope-type piers. This type of pier must have a barge in front for docking purposes.

A barge is an unpowered iron boat that can be understood as a water platform, so a slope-type dock is to place a tin boat next to the dock to serve as a loading and unloading platform.

This kind of terminal has many loading and unloading links, making it difficult for ships to get close to the front edge of the terminal, and the loading and unloading efficiency is low.

In terms of construction methods, the wharves built on Tianya Island are a combination of gravity type, high pile type and sheet pile type.

This aspect is determined based on comprehensive consideration of usage requirements, natural conditions and construction conditions.

The gravity construction method relies on the self-weight of some buildings and the weight of the filler within the structure to maintain stability. This is the main body of the wharf. Its advantages are that the structure has good integrity, is strong and durable, and is easy to repair after damage.

The bottom is constructed with high piles. Because the seabed is uneven, the engineering team used foundation piles to unify the height after measuring the topography of the seabed:

First, the lower part of the pile is driven into the seabed, and the upper part is above the water surface. Then gravity construction is used to send the main components of some building materials into the water, and the construction is completed around the foundation pile.

There is a permeable structure between the high piles, and waves and water currents can pass smoothly below the plane. This does not completely hinder the waves, does not affect seawater exchange, and can reduce siltation.

In the 2023 era, large prestressed concrete pipe columns or steel pipe columns were used. This is not possible now. Instead, cement anti-corrosion piles are used. The cost is lower, but the durability of the building materials will be much worse.

Wang Yi read the construction drawings and learned about the progress of the wharf construction. This way he had a good understanding of the project situation, so he brought his fishing rod to cast the barracuda.

After the new year, there will be a lot of flying shuttles on Mangrove Island, swarms of them underwater.

However, no big fish shoal was formed. They spent the cold winter to feed on the seabed around the mangrove island, and then went to the estuaries to lay eggs.

During this process, they will migrate short distances. When the weather cools down, they will overwinter deep in the sea until December. In the following spring, they will go to offshore estuaries to grow and fatten, forming a fishing season.

The five boats that came before were just here to catch barracuda. ​​Flying shuttles is very famous and is also liked by people in the city.

But there is little point in casting a net to catch pike here. It’s not that you can’t catch it, but you can get something, but the harvest is not good.

Like here on Tianya Island, fishing nets are continuously cast and put away, and the barracudas in the fishing nets are scattered here and there.

On the contrary, the harvest from throwing barracuda is very good.

This is because during the fishing season, barracudas migrate in dense shoals of large fish, but now they come to the mangrove island to eat, and they disperse after arriving. They are small groups and are not worthy of being caught by large fishing nets.

Large fishing nets are less efficient.

But they are very hungry, so throwing a fishhook with bait on it can tempt them very well.

This is Wang Yi’s first time fishing in such a simple way.

The current Mangrove Island area is definitely a paradise for fishing enthusiasts.

Making a nest? No need at all, just drop the hook and the fish will take the bait!

He cast the hooks and then retrieved them, catching barracudas one after another. He used a multi-hook fishing line to throw the barracudas. Some people could catch three or four barracudas with one cast.

The barracuda is full of energy, jumping up and down on the fishing line, and its slender and round body is shaking powerfully, giving people the feeling of just one word:

Run!

Two words.

Very moist!

Moreover, the barracudas here on Mangrove Island are big. The barracudas that can be caught in the Tianya Island area are thirty to forty centimeters. Here, after setting the hook, you can occasionally pick up fish that are more than half a meter long.

From time to time, someone suddenly loses the ability to pull the fishing line because a barracuda of more than one meter appears.

Qiu Weishui encountered this once. After setting the hook, she found that the fishing line was tight and she quickly pulled it back. As a result, the fishing line was pulled out even longer!

She hurriedly called to Wang Yi who was next to her. Seeing this, Wang Yi knew that she had encountered a big fish and went to help.

As a result, the fishing line becomes tighter and tighter, and the length of the fishing rod becomes longer and longer. The fishing rod bends and makes a creaking sound, like a long bow being drawn.

The situation is a bit strange!

Seeing this, Lao Huang immediately jumped into the sea to prepare for a big fight with the fish. It wanted to engage in a dog fight, and it wanted to show off its toughness as a good fisherman's dog!

So it entered the water.

After entering the water, I dived.

Got out after diving.

He got out and ran towards the boat with his tail between his legs.

There was a sound of ‘boom’.

The fishing line is broken.

Old Huang is running around even more energetically!

Wang Yi first pulled Lao Huang up and said, "What kind of fish is down here? Isn't it a barracuda? The fishing line has been broken!"

After hearing this, two nearby small boats came over, and the four people on the boat lowered their hooks one after another: "There is a big barracuda!"

Wang Yi said: "I saw you caught a big barracuda, but it didn't even break the fishing line!"

Wang Qianli, who just turned 20 this year, is very energetic. He said excitedly: "The barracuda we caught is not even big. This guy is as big as a human!"

Wang Yi took a breath: "Damn it, can a barracuda grow so big? Then it can eat people?"

They must have encountered a big barracuda.

Lao Huang's reaction was very strange. After diving just now, he ran back with his tail between his legs. He was obviously frightened.

Everyone changed fishing lines and put out bait one after another, and some people chopped up the caught yellowtail fish and threw them into the water.

The yellow croaker and the large yellow croaker are close relatives, both are kingfish, and their names are similar, but the meat quality is completely different.

The large yellow croaker is meat with garlic cloves, which is very tender and delicious.

The fish meat of yellow croaker is rough, its umami taste is not even a bit worse than that of large yellow croaker, and its fishy smell is not even a bit stronger.

But for barracudas with sharp teeth, yellow croaker and large yellow croaker are both good food.

The yellow croaker is even more delicious because it has more flavor!

This time it's a nest.

The big barracuda has a ferocious eating habit. It will eat the broken yellow carp immediately, and bite the hook as it eats.

very smooth.

The member who was bitten tried the weight in his hand and said: "This guy is good at it!"

Wang Qianli shouted to the island, and someone heard the sound and came over and brought the harpoon they wanted.

At this time, the big barracuda had a battle of wits and courage with the people on the boat. The fishing line was slowly retracted, and the fish swam up from the bottom of the sea.

Just now, Qiu Weishui and Wang Yi were unable to get it close to the water, so they didn't see its shadow clearly. This time they saw it clearly:

A huge shadow struggles in the water!

The length must be one and a half meters!

No wonder Lao Huang wants to run away. It’s not that Lao Huang is incompetent, it’s because Barracuda has Gundam!

After another ten minutes of entanglement, the big barracuda emerged from the water for the first time.

At this moment, Wang Qianli said "Hey!" and threw the harpoon down!

The sharp harpoon was inserted into the back of the barracuda's head at an angle.

Seeing this, Wang Yi shouted loudly: "Beautiful, this is the real barracuda!"

Tuna will die after being hit by a harpoon, let alone barracuda.

Even if a barracuda is one and a half meters tall, it will not weigh much.

It's just that the live fish are very strong, and after being stung, they can easily be picked up on the fishing boat.

Wang Yi went up to make some gestures and praised: "The size of this fish is really amazing. Does it taste the same as the ones that are thirty or forty centimeters tall?"

"They are all fish with clean intestines. The taste after the New Year is not much different." The members said generously.

Intestinal fish refers to fish such as barracuda that stay dormant in the deep sea during winter and do not eat. This kind of fish is often the most delicious in spring, and all the impurities in its stomach are used up in winter.

But some people said to Wang Yi: "The taste is similar, but the taste is different."

"The best fish is 30 to 40 centimeters. The fish below 20 centimeters is too small and tender and the flesh is too loose. The fish above half a meter is too old and doesn't taste good."

Wang Yi said: "Okay, then this fish will be used to stew soup. When I get back, I will stew barracuda soup with tofu for you to drink."

The members laughed: "You'd better invite the comrades from the construction team to drink, we don't want to drink this."

"Right, tofu is a good thing. Wouldn't it be better to stew cabbage with it than to stew barracuda?"

"I won't eat barracuda anymore. Braised in soy sauce is okay, and Teacher Wang's stewed in soybean paste is okay, but I won't eat the stew."

Between joking and joking, the barracuda slinging must continue.

The news that they had caught a one-and-a-half meter big barracuda spread quickly. Workers from the dock construction team and fishermen on several other boats came over to watch the fun and open their eyes.

Wang Qianli asked Gao Ming: "Hey, you just kept casting the net, how was it?"

Gao Ming said with a sneer: "No, not many people will gather together before the tide rises."

The members of Tianya Island burst into laughter.
