"Attention, everyone, go to the net, get off the net."

At this moment, the voice of the captain Liu Kunnan sounded, and everyone looked towards the stern, only to see a large ball of deep-water fishing nets ejected from the stern, quickly spreading, covering a radius of hundreds of square meters, and gradually sinking to the bottom of the sea.

The Black Pearl is just an offshore medium-sized fishing vessel, with a total length of 45 meters, a width of 9 meters, a depth of 4.2 meters, a maximum displacement of 3,997 tons, a draft of 3.65 meters, a main engine power of 2,920kw, a speed of 11 knots, a total length of 45 meters, a width of 9 meters, a depth of 4.2 meters, a maximum displacement of 3,997 tons, a draft of 3.65 meters, a main engine power of 2,920kw, a speed of 11 knots, a refrigerated seafood of 26 tons, 20 cubic meters of fresh water, and 32 cubic meters of fuel oil.

The deep-water nets on the Black Bead can go about 200 meters below the surface of the sea and can catch most of the economic fish in the offshore waters, especially common seafood such as squid, ribbon fish, octopus, sea bass, cuttlefish, barracuda and so on.

The wholesale price of these ordinary seafood is between ten or twenty or thirty yuan, and if it can be caught and returned with a full cabin, the total value is six or seven hundred thousand, excluding fuel oil and crew salaries, the boss can make half of the net income, so many people will enter the marine aquatic industry.

After the trawl was cast, the speed of the fishing boat began to slow down, and it was obvious that there was a huge school of fish below, and many fish had already entered the net, which would affect the speed of the fishing boat.

"Raise the net." Half an hour later, the speed of the fishing boat had obviously reached a critical point, and the captain, Liu Kunnan, an experienced veteran, hurriedly ordered the winch hand to start collecting the net.

"Lin Fan, come here, after a while, the fishing net will fall on the deck after being pulled up, and you can't treat people in that position." Li Hu saw that Lin Fan was still on the deck, and immediately greeted him.

It was the first time for Lin Fan to go to sea with a fishing boat, so he was full of curiosity about everything, and hurriedly retreated to Li Hu's side when he heard the sound: "Brother Tiger, how many fish can you catch in this net?" What kind of fish will there be? ”

"I don't know what kind of fish you have to pull the net when you catch the net, but judging from the impact on the speed of the boat, a net can reach four or five thousand catties at most. I estimate that even if it is less than 4,000 catties this time, at least there are more than 3,000 catties. Li Hu also has two years of experience in going to sea, so he estimated.

Cai Xingming, Wang Hongzheng and other crew members were turning the winch and slowly pulling the trawl net at the stern out of the sea, and suddenly a large bag of white sea fish appeared in front of everyone's eyes, but Lin Fan was not very familiar with these sea fish, and he didn't know what kind of fish they were, and they were worth nothing.

"Wow-"

The trawl moved directly to the top of the deck, the net mouth opened, and the sea fish in the net fell one after another, piling up on the deck like a hill, and the tail of the sea fish were all alive, not only jumping around, some big fish were still eating, biting the small fish around.

Lin Fan's eyes were about to look at the flowers, because he found that some of the fish in the fish pile were extremely huge, two or three meters long, and he was afraid that there would be more than a hundred catties; There are also some fish that are peculiar-looking, brightly colored, and very beautiful; There are also some huge turtle shells and the like mixed in.

"Let's move faster, sort and refrigerate the fish, throw the turtle shells into the sea, pay attention to whether there is rare seafood, some seafood should be put into the pool to raise, and it will be worthless if it dies." Captain Liu Kunnan immediately shouted loudly and ordered.

"Lin Fan, come with me, I'll introduce you to these sea fish." Except for Lin Fan, the others in the crew were obviously quite experienced, and when they heard the sound, they all dragged buckets to the fish pile and began to pick up the sea fish in it.

"Brother Tiger, I seem to know this kind of fish, it should be a barracuda." Lin Fan said to Li Hu while catching a herring fish nearly one meter long.

"Yes, that's the barracuda. The body of the barracuda is rounded with scales. The dorsal side is bluish-gray, the ventral surface is light gray, and the scales on both sides have black vertical stripes. It is an inshore fish that prefers to inhabit estuaries and bays, and may also enter freshwater rivers. Sexually lively, good at jumping, often swimming in groups in the countercurrent. Li Hu knows these common fish very well, and he talks about them endlessly.

"Fanzai, you see that this barracuda is actually the same, with a slender body. Do you know? The longest barracuda ever caught, almost two meters long. However, the longest barracuda I have ever seen is about 1.6 meters, and it was caught at sea in September last year, and it weighs more than 70 catties. Liu Shan, a crew member who was also picking up barracudas, smiled at Lin Fan and said.

The head of the barracuda is short and broad and the scales are large. The dorsal side of the barracuda is bluish-gray, the ventral surface is light gray, and the scales on both sides have black vertical stripes. Barracuda live in the estuaries of coastal rivers or in saltwater. Barracuda prefer to live in colonies and feed on organic matter in the soil at the bottom of the water.

Lin Fan glanced at it and found that there were still a lot of barracuda in the fish pile, so he asked the person next to him: "Is the barracuda expensive?" ”

"The barracuda in the outside market costs more than 40 yuan a catty, but the fish on our fishing boats are basically wholesaled to the seafood market, and they can basically be sold for more than 20 catties." It was Hao Gang who answered Lin Fan, and he was more familiar with these situations.

"Brother Gang, what kind of turtle is that? Don't you keep it? Lin Fan saw that Hao Gang was gently pushing a turtle the size of a millstone into the sea, and couldn't help but ask curiously.

There are two pairs of forehead scales on the top of this sea**, the snout is flattened laterally, and the front end of the upper jaw is hooked and hooked; 2 pairs of forehead scales; The dorsal armor shield is arranged in the form of a covered tile; The cuticular plates on the back are arranged in a tile-like pattern, with a smooth surface and alternating brown and yellowish patterns. The limbs are pinniped-shaped. Forelimbs with 2 claws. The tail is short and does not show the outside of the armor.

"It looks like a sea turtle, but it's actually a hawksbill turtle, a national first-class protected animal, an endangered species. So as soon as we catch it, we put it back in the sea, otherwise it's illegal. Hao Gang explained.

"That's right, I heard that last year, a graduate student studying abroad bought more than 100 tortoiseshell nails and returned to China, but he was found at the airport security check and convicted of smuggling precious animal products." Wang Hong, a crew member next to him, is a young man who likes to surf the Internet, adding at this time.

Lin Fan listened and carefully looked at this tortoiseshell, its dorsal armor was brownish-red, shiny, and had light yellow cloud spots; The ventral carapace is yellow with brown spots. The shield on the back of the head and limbs is black, and the shield rim is pale in color. snout long, laterally flattened; The anterior end of the palate is hooked and hooked; mandibular bone slender, mandibular symphysis long, only slightly shorter than the longitudinal diameter of the eye; The jaw margin is not serrated but has slender oblique straight stripes. The dorsum of the head has symmetrical large scales, and the forehead scales are 2 pairs; The anterior part of the neck has several small scales in the laryngeal and mental area.

The hawksbill turtle lives mainly in shallow lagoons and coral reef areas, where many caves and deep valleys provide a place to rest, and its diet includes invertebrates such as jellyfish, anemones, shrimp, crabs and shellfish, as well as fish and seaweed.

Everyone talked and laughed, and they didn't feel bored when they got to work, and Lin Fan didn't know most of the sea fish, so he asked while watching, and everyone introduced and explained them one by one, which also made him increase his knowledge a lot.

"Hey, this fish looks like a barracuda, but it doesn't have the length of a barracuda. What kind of fish are they? After a while, Lin Fan picked up a sea fish weighing four or five catties and asked in surprise.

The fish is elongated, nearly cylindrical in front and flattened laterally in the posterior. The whole body is rounded with scales, and the eyes are large and the eyelids are well developed. The teeth are small and villous and are born on the edges of the upper and lower jaws. There are two dorsal fins, the anal fin has 8 rays, and the caudal fin is deeply forked. The dorsal head of the body is blue-gray, and the abdomen is white.

"Oh, it's mullet."

"Mullet. But is it too much like a barracuda? If the body is longer and not so round, it will definitely be recognized as a barracuda. Lin Fan observed carefully, and then looked at the barracuda in the barrel.

"The mullet is similar in appearance to the barracuda, the main difference is that the mullet is short and the barracuda is slender; The mullet has large eye circles with a black inner membrane and median, and a small eye circle with a red eye crystal. However, mullet is much more expensive than barracuda, and the wholesale price is basically thirty or forty-one catties, and it is sold for seventy or eighty-one catties in the market. Hao Gang sighed.

Mullet is rich in protein, fatty acids, B vitamins, vitamin E, calcium, magnesium, selenium and other nutrients, the meat is delicate, the taste is delicious, especially the mullet before the winter solstice, the fish body is the most plump, the belly and back are full, particularly fat, often used as the seafood delicacy of the hotel restaurant. It can be eaten by ordinary people, especially suitable for people with weak constitution, malnutrition, spleen and stomach qi deficiency, and people who do not want to eat and drink, such as pediatric anemia.

Mullet meat is thick, delicious, nutritious, containing protein up to 22%, no fine bones, the fish meat is mellow but not greasy, not only can be used as a banquet delicacy and people's food in the restaurant, and if it is processed into surimi fish balls, fish fillets, canned fish and other products, it can become a nutritious, convenient and delicious food, and its fish roe can be made into caviar, which is a well-known delicacy at home and abroad.

After all the sea fish were sorted, they weighed more than 3,200 pounds after the scales, and there were still a lot of huge shells of the turtles thrown into the sea, and there was a lot of garbage left on the deck.

"Why do you put all this garbage in it? Don't you throw it into the sea? Lin Fan was very puzzled when he saw Cai Xingming and they packed all the garbage in the trash can.

"These are marine litter, which pollutes the seawater very much, causing the deterioration of the marine environment and bringing many marine life to the brink of extinction. Therefore, we all have a rule when we go out to sea to fish, that is, the marine garbage from the Internet must be packed and taken away, brought back to the fishing port and handed over to a special department for disposal, so as to contribute to the purification of the marine environment. ”

Listening to Cai Xingming's words, Lin Fan nodded, although he had never been to sea before, he had also seen some news, some black-hearted manufacturers specially transported garbage to the sea to dump it, and even some neighboring countries specially threw garbage into the waters of Huaguo.

After more than two hours of busywork, the net was finally packed, even the deck was rinsed, and everyone was ready for lunch. And the Black Bead also slowly moved forward, ready to change places to find an opportunity to get off the net.

Compared with other fishing countries in the world, China's fishery level is quite backward, especially in the distant-water fishery, far behind Iceland, Japan, Norway, Denmark, and Russia.

In this way, Huaguo's base in offshore fisheries is the largest, so over the years, the fishery resources in the offshore waters have gradually become scarce, like the Black Bead can catch more than 3,000 catties in one net is considered lucky, but the next net must leave this sea area to find another opportunity.

At present, China is vigorously developing the ocean-going fishery, and many shipbuilders in the country are making every effort to overcome some key technologies of the ocean-going fishing vessels, and strive to be able to independently manufacture large-scale ocean-going fishing vessels.

In particular, deep-sea fishery resources have always been a forbidden area for human beings, because the world's deepest fishing nets can only penetrate about 1,000 meters into the sea surface, compared with the general depth of the ocean for thousands of meters, human beings can only operate on the surface. >
