There are many types of wrasses, and their colors vary.
Why different types of fish can recognize wrasses as wrasses at a glance when hunting and stop attacking is something that scientists and biologists cannot explain.
Some people say that the flat body of the wrasse is developed for the convenience of medical practice. The reason why other fish can recognize the wrasse as a wrasse at a glance is because of its flat shape and bright colors.
Of course, this argument is totally untenable.
The flat-bodied fish in the ocean have all disappeared, and there are countless brightly colored fish. If those ferocious ocean predators relied on these two points to identify the wrasse, the wrasse would probably have been accidentally injured by their own sick ones.
Fang Youqun stared at a wrasse in a fish tank and wondered, "I didn't expect this fish, which looks so fierce, to have such a good temper. It must be a sacred fish."
Xiang Yang suddenly burst out laughing, "Who told you that wrasses have good tempers?"
Fang Youqun was immediately surprised. "Isn't that so? Aren't they doctor fish in the ocean?"
Zhang Qicheng smiled and said, "You probably have a misunderstanding of the term good temper. Doctors are there to save lives, but who told you that those who save lives must have good tempers?"
"Ah?" Fang Youqun looked at Xiang Yang, extremely puzzled.
Xiang Yang smiled and said, "It's true that wrasse is a doctor fish, but no one says that doctor fish can't have a temper, right? In fact, wrasse has a very bad temper and is very aggressive."
When the wrasse is practicing medicine, the fish need to line up quietly and wait for treatment. If a fish cuts in line or deliberately makes trouble, the wrasse will stop practicing in anger. The fish need to wait for the sick fish to put the order in order themselves and form a circle and keep asking the wrasse for help. The wrasse will continue practicing medicine only after the fish has calmed down.
In addition, wrasses will only treat fish that are larger than themselves. As for fish that are smaller than themselves, wrasses will charge recklessly no matter what kind of fish the opponent is. For fish of the same size as themselves, wrasses even like to challenge each other to see who is stronger, themselves or the opponent.
In an aquarium, only young wrasses are kept together with other fish. Once the wrasses grow big, they will constantly fight with other fish and can easily cause considerable damage to other fish.
"Uh." Fang Youqun blinked, "This kind of temperament... is indeed violent."
Xiang Yang smiled. Even if the wrasse was irritable, it was because of the other fish that spoiled it.
When faced with a duel initiated by a wrasse, many fish will generally avoid it if possible. If they really cannot avoid it, they will continue to accommodate the wrasse during the duel.
While Xiang Yang was explaining, all the wrasses in the catch were cleaned.
The crew members asked Xiang Yang, "Captain, what about these catches? Should we keep them or freeze them?"
"Let him go." Xiang Yang said.
The crew members were shocked. "Release it? This is more than a thousand kilograms of catch, at least tens of thousands of dollars worth of catch."
"Yes, let them go." Xiang Yang nodded and said, "We have made a fortune by catching these wrasses in this net. These sea fish caught with the wrasses are basically sick fish. I don't know if they have parasites or infections. Let's let them go."
The crew members didn't feel any better after hearing this.
Especially those fishermen from Yanlong Village.
In the past, a catch of over a thousand kilograms was definitely considered a big harvest in Yanlong Village.
Now Xiang Yang said he would let them go with just a few words, and their hearts felt like they were bleeding.
Zhang Qicheng gave Xiang Yang a thumbs up and said, "There are very few conscientious fishermen like you nowadays. If the fish is sick, it's okay. It can usually be found before cooking and picked out. It will not cause harm to humans. But if the fish with parasites are caught, it will be very harmful."
Xiang Yang smiled. This was probably one of the reasons why he ordered the fish to be released.
It would be fine if these fish were circulated in supermarkets or big hotels. Whether it is the chefs who cook seafood in the big hotels or the individuals who go to the supermarket to buy seafood, they will generally check whether the seafood is fresh and whether it has any disease.
The only thing we are afraid of is that it will spread to small bars or nightclubs that serve sashimi.
Of course, even if these fish were released back into the ocean, most of them would not survive.
Even if there are still wrasses in this sea area, given their aggressive temperament, if the group loses so many members at once, the remaining wrasses will definitely go on strike.
“Brother Yang, do we need to release this one too?” Fang Youqun was holding a turtle as big as a washbasin, and asked with some concern, “A turtle this big must be very valuable, right?”
Xiang Yang looked at the turtle and asked, "Do you want to eat it?"
Fang Youqun quickly shook his head. He was a native fisherman. The older generation often said that turtles were long-lived creatures with spirituality, and that they would generally release turtles once they were caught.
Fang Youqun never listened to the advice of the elderly, but since he was a child he had been influenced by them and he also did not eat turtles.
But just because he doesn't eat the turtle himself doesn't mean he won't sell it for money. He is capable of doing such a thing.
Xiang Yang looked at the two-faced turtle.
When it comes to turtles, the first thing many people think of is protecting animals.
In fact, not all turtles are protected animals.
There are many types of turtles, and even protected animals are divided into different levels of protection according to their different species.
Some turtles are listed in the World Red List as world-class protected animals.
Some are first-class protected animals.
Some are second-class protected animals.
In others, the scope of protection is limited to only a few provinces.
This two-faced turtle is not listed among the protected animals and is obviously not a protected animal.
"If you don't want to eat it, just let it go." Xiang Yang said. Xiang Yang believed that turtles were spiritual, and he was unwilling to catch or trade such primates.
Unless it's valuable.
It's not about protecting animals.
Fang Youqun held the two-faced turtle and walked towards the side of the boat reluctantly. Would anyone buy such a big turtle for a thousand yuan? It would be a pity to let it go!
Halfway through the walk, Fang Youqun's eyes suddenly rolled. He immediately turned around, looked at Xiang Yang and said, "Brother Yang, this turtle is probably sick too. It won't survive if we release it. How about we keep it together with the wrasse? After the wrasse cures its disease, we can send it to the ornamental fish market?"
Xiang Yang burst out laughing. Although the wrasse was very enthusiastic about the noble cause of saving lives and healing the wounded, the wrasse that had just been caught would not treat sick fish for a very long time because it was frightened. It might be a bit difficult to rely on the wrasse to treat the turtle, because Xiang Yang didn't know whether the turtle could hold on until the wrasse was willing to resume its old business.
