My Deep-sea Fishery

Sardines need to be caught with boats.

In the case of large boats, fishermen cannot see this kind of fish at all because of their vision.

When Xiang Yang was a child, he saw fishermen fishing for sardines in small boats.

Hundreds of small fishing villages formed a line, pulling fishing nets mighty and mightily, encircling a group of sardines.

Now, although there are several small lifeboats on Xiang Yang's big ship, the number is too small, so it is better to use the big ship directly.

Soon, the three fishing boats cast nets together, and then trawled forward, forming three long waves on the sea.

The tropical sea breeze is very warm and feels very comfortable on the face.

Xiang Yang stood at the bow of the boat, enjoying the sea breeze and taking a sip of the iced drink.

Soon, as the waves rolled, the fishing nets began to be slowly pulled out of the sea.

"Wow."

As the nets were unwound, mountains of sardines piled up on the deck.

"When the sardines were in the sea, they looked dark blue. Why did they turn silvery white when they were on the deck?" Fang Youqun wondered.

Xiang Yang smiled, "It doesn't matter what color it is, there are so many catches, hurry up and take someone to clean them up."

"Yes, Brother Yang." Fang Youqun hurriedly led people into the cabin to carry foam boxes and crushed ice.

With so many sardines, it is certainly impossible to bring them all back alive.

Most of them have to be processed into fishmeal or canned fish, and a small part will be wrapped in ice and brought back to the shore. Only a very small part of the big ones will be put into the live water tank and brought to the shore alive.

All the crew members were dispatched, and some of them, led by Fang Youqun, threw the sardines into the foam box and wrapped them with crushed ice.

Under the leadership of Xia Pengjie, some people transported the sardines into the live water tank.

Even the people in the engine wheel group, under Zhou Wang's organization, began to look for those larger sardines one by one.

Looking at the busy crew members, Xiang Yang was too embarrassed to stand and watch, so he also went up to help.

Speaking of it, sardines are actually a very important part of the marine ecological environment. Not only does it taste delicious, it is also a purifier of the ocean.

Sardines will help humans remove toxic gases near the coast, saving certain areas from becoming a threat to marine life dead zones.

In the journal Ecological Research, researchers report that starving sardine schools will clear Namibian waters of phytoplankton, which will reduce the production of toxic gases in the area.

This phenomenon will have a profound impact on the mitigation of global warming.

For as long as a century, the waters off the Atlantic coast of Namibia have been found to be emitting toxic sulfur dioxide gas, which is often accompanied by the death of large numbers of fish and marine crustaceans.

It is only in recent years that researchers have begun to carefully study the emission of methane and hydrogen sulfide gas below the surface of the sea.

From the images transmitted by satellite, people can also clearly see that the special blue-green band-shaped sea area in this area is similar in size to the total area of ​​New Jersey in the United States.

Many scientists think the gas is released by the decay of phytoplankton, which coats the seafloor in silt several meters deep.

Two years ago, researchers Andrew Bacu of the University of Miami in Florida and Sklar Vickers of the University of Campus in South Africa simultaneously discovered a significant pause in the trend of this gas emission.

They later determined that this pause occurred at the same time as the native sardine breeding season.

They calculated that millions of sardines ate the phytoplankton that would have drifted toward the shoreline, thereby reducing gas emissions.

Baku also stressed that the link between the two phenomena still needs to be proven, but Namibia's experience also has serious warnings for other regions, such as Morocco and California.

These areas also have similar nearshore waters suitable for phytoplankton growth. Global warming will promote the large-scale reproduction of phytoplankton, and these sea areas will also become future marine life death zones.

"Imagine how much methane and sulfur dioxide, which can lead to greenhouse effects, can be added to the atmosphere if the sardine fishing is doubled," Baku said.

Therefore, from an environmental point of view, Xiang Yang also disapproves of wanton fishing of sardines.

If it was not such a huge group of sardines encountered this time, Xiang Yang would not have given the order to catch 100 tons.

Even if he met such a huge group, Xiang Yang only ordered to catch 100 tons.

The figure of 100 tons sounds very scary, but in fact, compared to three huge fishing boats of the thousand-ton class, a mere 100 tons of sardines is nothing at all.

"Captain, I think we can still catch another net. The number of sardines around is not only not decreasing, but is still increasing." Zhou Wang shouted at Xiang Yang while cleaning up the catch.

Xiang Yang looked around and shouted, "Clean up the catches on the deck first."

With that said, Xiang Yang put down the two sardines in his hand, got up and went to the side, washed his hands with clean water, took out the walkie-talkie and started calling Chen Qingsheng.

"Boss, are you looking for me?" On the other boat, Chen Qingsheng saw Xiang Yang calling him, and quickly picked up the walkie-talkie and replied.

"How many sardines did you catch in the net just now?" Xiang Yang asked Chen Qingsheng.

As soon as Chen Qingsheng heard that Xiang Yang asked this question, he immediately became excited, and quickly replied loudly: "Captain, a great harvest, you don't know about the net just now, our captain is now piling up sardines like a hill, conservative estimate There are at least sixty or seventy tons, and this number will only increase, definitely not less."

Xiang Yang nodded, this number is similar to what Xiang Yang estimated.

Chen Qingsheng's fishing boat can catch more than 100 tons of fish in one net.

There are swarms of sardines gathered below, as long as the net is cast, the net must be full.

Because of the mesh size of the fishing net, some smaller sardines will get out of the mesh, and the last net can catch 60 to 70 tons of sardines just right.

"Okay, take someone to clean up the sardines on the deck quickly. It's best to freeze all the sardines. Some of the bigger ones should be sent to my boat." Xiang Yang said.

The price of some larger sardines is different from ordinary sardines.

If it is also frozen in a foam box and sold as ordinary fresh food, it would be too wasteful.

Chen Qingsheng's gillnet ship only had storage compartments and freezing compartments, but no living water compartments, and some larger sardines could not be kept alive, so it was the best choice to send them to Xiang Yang's processing mothership.
