Golden Fishery

The reason why Sanders applied to Qin Shiou was because he was worried that there would be another racial outbreak in the cultivation process of Luminous sail jellyfish. basket color,

Jellyfish have an amazing ability to reproduce. If you want to breed this thing, you must prevent the crisis of the population.

Different jellyfish have different reproductive methods, but they are all powerful, otherwise they would not have lived on the earth for so long. You must know that in the age of dinosaurs, jellyfish appeared in the ocean, and it has continued until now, and its contemporaries All creatures are wiped out. They have seen so many vicissitudes of the earth, but they are still alive and well.

Qin Shiou has been learning about jellyfish these days, so he understood what Sanders meant. He said, "It can be cultivated. We have leatherback turtles here. We are not afraid of their small-scale outbreak."

In fact, he has the idea of ​​raising jellyfish, firstly to feed leatherback turtles, and secondly to see if new projects can be developed, but if he raises it, he must control the scale, and the outbreak of jellyfish is really not fun.

After the research project was approved for Sanders, Qin Shiou filled two luminous sail jellyfish in a small fish tank to surprise Winnie.

In the end, after thinking about it, he put down the small fish tank again, let's make it night, and create a dream world for Wei Ni to see at night.

After returning to the villa, Wei Ni was entertaining several people. These people were formally dressed, some had microphones in their hands, and some had video cameras at their feet.

Qin Shiou thought it was someone from the Guinness Book of World Records who came running again, and when he took a closer look at them, they had Newfoundland TV on them, and it turned out to be a TV reporter.

Seeing Qin Shiou, Winnie said, "Oh, that's great. I'm about to call you back. A TV station is here to interview our fishing ground. Come entertain me."

Qin Shiou shook hands with the reporters, and the reporter in charge of the interview explained the purpose of his visit. The topic of their interview was the jellyfish disaster, because it was Qin Shiou who first discovered the crisis and reported it to the Ministry of Fisheries, and his fishery was the least affected. Therefore, it has been valued by TV stations.

Canadians attach great importance to building their own brand, so they welcome TV interviews. When watching TV, if it is a live broadcast rather than post-editing, you often see young people suddenly appearing in the camera to steal the spotlight.

The two sides discussed the interview issues first. Then Qin Shiou took them to the beach.

The reporter looked around, and all he could see was the blue water. Where were there any stranded and dead jellyfish? He subconsciously asked, "Your fishing ground has not suffered from jellyfish disasters."

Qin Shiou laughed and said: "No, it's just that I dealt with it overnight after I discovered the problem, and these jellyfish have been sent to the ice bank.

In the later stage, I plan to deal with it to make fish and shrimp feed and put it into the fishery. "

After the interview, the reporter said that they will publish a special report in the evening, and there will be an interview with him, please pay attention to it.

While eating dinner, Winnie turned on the Newfoundland TV station, which is a very important local TV station. Its status is equivalent to the satellite TV in the province of China. It is not easy to land the special programs here.

At the beginning of the program, the details of the jellyfish disaster were first introduced.

This time, not only the waters of Newfoundland, but also the waters of Nova Scotia were affected. But the worst was Newfoundland. In the spring, the southeast wind was strong, and the sea breeze blew the jellyfish into the Gulf of St. Lawrence. Now, from TV, the bay is full of stranded dead sail jellyfish.

The original sail jellyfish was dehydrated and died in the sun, and then the body color changed to light black due to a chemical reaction, and the snow-white beach turned into light black, which looked shocking.

Qin Shiou sighed: "Fortunately, we started early, if the beach of our fishing ground becomes like this"

As he spoke he shook his head. So sad.

After introducing the situation of the disaster, the program carried out science popularization. Firstly, it introduced the types of jellyfish and their reproduction, and the reproduction issue was given the first explanation.

Jellyfish reproduce through pods. After their parent bodies sink to the bottom of the sea, they can move on the appendages. While moving, they will split out the pods and stay on them.

As time and conditions permit, these pods can reproduce more polyps, thus self-replicating. Even if the mother only leaves tens of thousands of fertilized eggs at the beginning, it will eventually evolve into billions of polyps

And when the polyp grows further, the small jellyfish will split out one by one, and the final number will reach tens of billions.

The most powerful one is a lighthouse jellyfish, which is very small, only five millimeters in size. They grow up from small to large, and after mating when they grow to maturity, they will not die, but immediately rejuvenate, become young, and then grow again, which is incredible

Now many marine scientists in various countries are studying this kind of jellyfish. In an environment with qualified resources, this kind of lighthouse jellyfish can live forever and go through life cycles again and again. From this point of view, it looks like the legendary fire phoenix. This is a mythical beast. what.

Another point is also scary, that is, jellyfish polyps are not only huge in number, but they are also dormant.

That is to say, when the external conditions are not suitable for reproduction and growth, they can fall into dormancy, and they can be dormant for up to a hundred years. When the environment is suitable, when will they reactivate.

But this is not the reason for the explosion of jellyfish populations. Even if their reproductive ability is so good, they can only linger in the ocean before, but they cannot explode like this.

According to the analysis of marine experts invited by the TV station, there are two reasons for the jellyfish outbreak. One is the reduction of natural enemies, the other is the ideal living environment due to the greenhouse effect, and the eutrophication of seawater leads to abundant food.

In the past 6 years, humans have obtained 300 million tons of fish from the ocean, which are all wild animals, not farmed by humans. At the same time, humans have discharged more than 300 million tons of garbage into the ocean, so the entire ocean has undergone great changes.

In addition, the rapid development of human society produces a large amount of industrial and domestic waste, and sewage discharges lead to more and more excess nutrients in the ocean. As a result, algae plants are flooded, red tides, and Enteromorpha are prevalent. Therefore, algae plants provide sufficient nutrients for plankton. The food, the plankton multiply, and the jellyfish that feed on the plankton begin to run rampant.

The outbreak of jellyfish is behind the withering of marine fish resources. The marine food chain has always presented a pyramid structure, from diatoms and single-celled plants at the bottom to large fish and marine mammals at the top, and this structure has been stable for hundreds of millions of years.

However, the outbreak of jellyfish populations caused them to plunder plankton, making fish lack food sources, and the marine food chain was broken. That's why fish farmers pay so much attention to jellyfish outbreaks.

Perhaps for the entire ocean, a large outbreak of jellyfish in one area has little impact on the whole, but for the farms in that area, it is a disaster.

In the news, the camera keeps cutting from various fishing grounds. There are stranded dead jellyfish on the shore, and a large number of dead fish floating on the sea surface with their bellies turned upside down. Some fishing grounds have just stocked fish fry in spring, and these fish fry have all been wiped out. To be continued . ~ Search for blue color, you can read the following chapters in full
