Although species invasion will have a certain impact on marine life in a certain sea area, this impact is insignificant compared to the huge damage caused by humans to the ocean.
The ocean has a very strong self-regulating ability.
When species invade, the ocean can gradually balance itself through slow self-regulation.
But if the ground is scratched by the ground net once, it will take a very long time to recover.
Xiang Yang pondered for a moment and said, "Pearl swallows are very precious. Don't be afraid of hard work. Let's catch a few more and spread the news that there are pearl swallows in this sea area. I believe it won't take long before all the fishermen will catch them."
The crew members all nodded, indicating their agreement with Xiang Yang's statement.
Xiang Yang also went down to the bottom of the sea again.
After catching more than ten pearl swallows, Xiang Yang discovered another very beautiful sea fish.
From a distance, the body of the fish looks like a green jade plate emitting pearly luster. On the jade plate, there are black stripes, which looks extremely noble.
This is a very valuable and beautiful tropical ornamental fish, the split-lipped fish.
The cleaverfish is famous in aquariums for its pretty, neighborly appearance.
However, what really makes the cleaverfish expensive is not its handsome appearance, but its bold behavior.
In the aquarium, the cleaver fish can be kept together with most of the ferocious marine fish. Not only will those ferocious marine predators not prey on the cleaver fish, on the contrary, there will be a magical scene in the aquarium where the ferocious marine fish opens its mouth and the cleaver fish will actively swim into the mouth of the ferocious marine fish.
Not all fish dare to swim into the mouth of a big fish. The bold behavior of the split-lipped fish is very eye-catching to aquarium enthusiasts in the aquarium. Its unique behavior also adds a lot of value to its expensive price.
Xiang Yang stared at the split-lip fish.
This split-lip fish is less than ten centimeters long, which is really small among marine fish.
This is similar to what Xiang Yang knew. The split-lip fish is a small warm-water marine fish. It is widely distributed in the Pacific and Indian Oceans. It generally likes to live in coral reef areas. It is small in size, and its body length is generally six to ten centimeters.
Xiang Yang was hesitating whether he should catch the split-lip fish.
In theory, the cleaver is a very precious ornamental fish in marine aquariums. Like the sunfish, the cleaver is also a very famous doctor fish, and is deeply loved by marine aquarium enthusiasts.
Sunfish is a doctor fish because it can secrete a special substance that can cure many fish diseases.
The cleaver fish is a doctor fish because it not only has a long mouth and thick lips but also sharp teeth. It is born to be a doctor. It usually lives in coral reef areas. Angel has the ability to prey on parasites from various fish.
However, the cleaver is a warm water fish, and Xiang Yang's destination is the Arctic Circle. Xiang Yang was worried that if he caught the cleaver, it would not be able to return home alive with him.
In comparison, ornamental fish become worthless as soon as they die.
Just when Xiang Yang was hesitating, the split-lip fish actually swam to a depression in the coral reef under Xiang Yang's guidance and began to spit out a kind of thread-like mucus from its mouth.
Xiang Yang was stunned for a moment, then he remembered that the split-lip fish and the parrot fish belong to the same family, and both have the ability to weave pajamas. Whenever it is tired and needs to rest, it will spit out mucus from its mouth into the coral reef to weave a piece of pajamas and wrap itself up like a cicada pupa.
Xiang Yang was suddenly at a loss whether to laugh or cry. Was this fish preparing to take a nap
After thinking about it, Xiang Yang decided to let the split-lip fish go this time.
A split-lipped fish can be of great help to other fish in a marine fish colony.
As a doctor fish, the cleaverfish works very conscientiously and responsibly. Usually no fish will attack it. Even the extremely ferocious shark, when seeing the cleaverfish, will docilely allow it to catch parasites on its body. Sometimes, it will take the initiative to open its bloody mouth and ask the cleaverfish to clean its mouth.
The cleaverfish are also very courageous. They often don't care how ferocious and domineering the other party is. No matter what kind of ferocious marine predator it is, they dare to drill into the other party's mouth to catch parasites for the other party and clean the dirt for the other party.
The food of the split-lipped fish is precisely those parasites or food residues.
The wrasse and parrotfish belong to the same family, the wrasse family. Both have the habit of weaving pajamas and, naturally, have the personality-changing ability that most wrasses have.
No matter how many cleavers there are in an area of sea, there is often only one male fish.
Only when the male fish disappears or dies, will the largest female fish in the sea area replace the previous male fish and take on the responsibility of guarding the territory.
It only takes about two days from the death of the last male fish to the transformation of the largest female fish into a male fish.
At this time, Xiang Yang saw a crew member wearing a diving suit. He swam quickly to the side of the split-lip fish by swinging his limbs. Then he stretched out his hand and grabbed the split-lip fish that was weaving pajamas, and stuffed it into the net bag around his waist. He did it in one smooth move.
Xiang Yang was stunned for a moment. Just as he was wondering whether he should swim over to ask the crew member to release the split-lip fish, he saw the crew member swimming towards him quickly.
As he swam closer, Xiang Yang looked through the helmet and found that it was Fang Youqun.
When Fang Youqun saw Xiang Yang, he immediately took off the net bag from his waist, and then danced with joy while showing it off to Xiang Yang.
Xiang Yang looked into the net bag through the mesh.
Wow, no wonder Fang Youqun is so proud.
I saw that Fang Youqun's net bag was almost full, with more than ten pearl swallows, four or five split-lipped fish, and other seafood.
Xiang Yang grinned. It seemed that there were quite a lot of split-lipped fish near this sea area. He would just catch as many as he could. At worst, he would deal with them together with the pearl swallows when he reached the Pioneer Beach.
As for this coral reef area, without the doctor fish, what will happen to the other big fish
Xiang Yang was actually not worried about this.
The cleaverfish is just a type of doctor fish that specializes in cleaning parasites.
There are actually a lot of doctor fish in the ocean.
Not to mention the sunfish that can secrete unknown substances, there are several species of doctor fish in the family of Ceratophyllum alone. The bicolor cleaver and the insectivorous cleaver are both more important marine doctors than the cleaver.
Moreover, since the front half of the body of the bicolor cleavage fish is gray-black, its appearance is much lower than that of the cleavage fish, and its ornamental and edible value is extremely low, so few people catch it.
The insectivorous cleaver is even worse. Although it is very beautiful when it is a young fish, it no longer has bright colors when it grows up, and few people like it.
