These are still small things.
Xiang Yang had also seen in the news that a woman released two crocodiles into a lakeside park, which caused such a sensation that the police had to be dispatched to pull the two alligator snapping turtles out of the lake.
Xiang Yang didn't know yet what impact these pearl swallows would have on this sea area, but after seeing them swimming leisurely and not panicking and running away when he swam close to them, Xiang Yang knew that there should be no natural enemies of the pearl swallows in this sea area.
If these pearl martins were allowed to reproduce on a large scale, the consequences would be serious.
Xiang Yang reached out and caught a plump Pearl Swallow.
The body of this pearl swallow is silvery white, and both its body and fins are covered with black stripes and bright white spots.
On the back of this pearl swallow, there are two separate and upright dorsal fins. The slender fins have a sense of elegance and transcendence, and coupled with the deep "swallow tail", it gives people a sense of lightness and elegance.
When Xiang Yang saw it, he was immediately more certain that this group of pearl swallows were released by passing tourists.
The Pearl Swallowtail, which looks so beautiful, is obviously the product of artificial improvement in quality, and it is the best quality among the improved varieties.
With a rather gloomy expression, Xiang Yang stuffed the pearl swallow into the net bag, and then swam towards the sea.
"Hey, Captain, how did you get up so quickly? Did you catch something good?" The crew member who stayed on the ship saw Xiang Yang just went down, and immediately popped his head up and asked curiously.
The crew member who asked the question was from the engine room crew, a junior whom Xiang Yang recruited from the Maritime University.
Xiang Yang took off the net bag from his waist with an unpleasant look on his face, handed it to the crew member, and said helplessly: "This is what I fished out from the bottom of the sea, you can see for yourself."
The few crew members who stayed on the boat came over curiously to see what was happening.
"Hey, is this a fiddler crab?"
"It looks like a fiddler crab. How could a fiddler crab appear under the sea?"
"Fuck, this one is even more outrageous, isn't this a long-finned swallow?"
The long-finned swallowtail is also another name for the pearl swallowtail.
Pearl Swallow has different names in different places, such as Holy Evil Angel, Long-Fin Rose, etc.
Several crew members looked at Xiang Yang in confusion.
Apparently, several crew members knew the habits of the famous fiddler crabs and pearl swallows.
Xiang Yang was quite speechless and said, "It should be some idle tourist who released it. This fiddler crab is okay, I only saw this one, but these pearl swallows are in groups, God knows how many there are in this sea area."
The Pearl Swallow is a mouth-brooding fish.
After the female fish lays pink eggs, the male fish will hold them in his mouth to incubate them.
This method of hatching makes it difficult for the eggs of the Pearl Swallow to be preyed upon by other animals, and also greatly improves the hatching rate of the eggs. A group of Pearl Swallows can give birth to dozens or even hundreds of Pearl Swallows at a time. If there were no constraints from natural enemies, this sea area would probably soon be completely dominated by Pearl Swallows.
And this sea area happens to be the Coral Sea. The pearl swallowtail can use the poisonous stingers of the coral to resist those ferocious marine predators such as sharks. In the coral reef, those weaker marine predators cannot even defeat the pearl swallowtail.
The crew members were very excited. "There are swarms now? What are we waiting for? Let's fish!"
"What are you still fishing for? Captain, do you remember where the fish are? I'll throw a net down."
"If we can catch a net of pearl swallows, we will make a fortune."
"Yes, that's right. I've heard that too. The Pearl Swallow is in great demand in the market. As long as we bring back a shipload, it will become hard currency immediately."
Xiang Yang rolled his eyes. This was a tropical fish, and their destination this time was Antarctica.
Moreover, the pearl swallowtail is different from the spider crab.
Although spider crabs live in the tropics, they live under the reefs on the seabed. The water there is actually very cold, with almost no temperature. If you put your hands in without any protection, you may even get frostbite.
Pearl swallowtails are different. They swim among coral reefs and need very high temperature sea water to survive.
Even if we catch a boatload of pearl swallows now, I'm afraid we can just make specimens of them after we take them to Antarctica.
"We have to salvage them, but we won't bring them back. We'll just dispose of them when we replenish supplies at Pioneer Beach," Xiang Yang thought for a moment, then said, "I'll go down first. When you see someone coming up from the water, remember to call them and tell them that there are pearl swallows under this sea. Let them not miss any that they see, no matter how big or small, and salvage as many as possible. We'll try our best to clean up all the pearl swallows under this sea area. Even if we can't clean them up, we'll at least slow down the speed of the pearl swallow species invasion."
"ah?"
The crew members all stared at Xiang Yang in a daze, unable to understand what was happening for a moment.
After a while, one of the crew members asked in doubt: "Captain, are you saying that the pearl swallows under this sea are alien species?"
Xiang Yang snorted, "The habitat of the Pearl Swallow is very narrow. It has never reproduced in the South China Sea. Moreover, the Pearl Swallow I caught had very obvious signs of artificial breeding. If it wasn't released by a tourist who came here to play, then it would be really weird."
Hearing this, the faces of several crew members turned serious.
Species invasion, especially in the cradle of life like the ocean, is no joke.
If it is not handled properly, it will bring a devastating disaster to the original marine life in the sea area.
The Xisha fishing ground is a very important fishing ground for our fishermen. Mackerel, red fish, sea cucumber and abalone are all fish with very high economic value. We are all fishermen and we cannot ignore this very serious issue.
"Captain, how long will it take to salvage it? Ask our colleagues underwater to come up, and we will just use the traction net to tow it up again." A crew member said seriously.
"This is nonsense. This is a coral reef area. Using a traction net? That would be a real disaster." Another crew member immediately retorted.
The so-called ground-grabbing net is an ordinary fishing net with sharp iron hooks hanging at the bottom. When dragged by the fishing boat, those iron hooks will firmly grasp the seabed. Under the huge power of the fishing boat, even the hardest reefs can be broken into pieces. With one net, the ground in the entire sea area will be scraped up directly, and the bottom reptiles, middle-layer fish, and surface fish will all be caught clean.
"No." Xiang Yang refused without hesitation: "Using a traction net in the coral reef area, once it is dragged, this area of the sea will not be able to recover for hundreds of years, and we don't have a traction net on the ship."
