Islands and islands, no sea is not an island.

Fantastic wonders are nice, and world-class resorts are nice, but the real treasure is the ocean itself.

The planning of the island was stared at by his daughter-in-law, and Qi Zheng shifted his energy to the development of the sea area.

What Qi Zheng won was not only Pishan Island, but also the surrounding 25 square kilometers of sea area that could be developed.

Qi Zheng intends to build it into a "marine ranch" backed by a charming island, rippling blue waves, and fishing boats.

Marine agriculture and animal husbandry enable human beings to manage the ocean and aquatic organisms in the same way as ranches and cattle and sheep, which is a modern way of fishery development.

In fact, compared to land-based pastures, the sea has pastures – that is, traditional fishing grounds.

And China's four major fishing grounds, or the four major natural marine ranches, make people sigh. These pristine marine ranches have been affected by overfishing and land-based pollution, and the ecosystem is unbalanced and fishery resources are declining, and natural ranches no longer exist.

And Qi Zheng wants to challenge this sea area where the water environment is deteriorating and the quality of seafood is declining, and rebuild a marine ranch and a blue granary!

......

At the Pishan Island wharf, large containers are neatly placed there, and there are many "skylights" around each container; in addition, there are concrete component reefs, granite reefs, and treated old ship reefs stacked next to them.

These aren't just containers or garbage, they're all artificial reefs that sink to the bottom of the ocean and build a solid house for marine life to inhabit them.

The fishing grounds around Pishan Island are seriously lacking in marine biological resources, and there have been no fish to catch before, and they are all small fish and shrimp.

The construction of marine ranching is a complex and systematic project, including a series of steps such as seed breeding, primary productivity improvement, ecological restoration, and whole-process management. Among them, the release of artificial reefs is the basic means.

Qi Zheng waved his hand, and the fishermen shouted to carry these artificial reefs onto the boat, and then sailed out into the sea, they were going to work.

Sailing out of the confines of the beach bathing, the boat stopped.

Under the guidance of Jiagu technicians, the fishermen began to cast artificial reefs on the seabed.

These jobs are a breeze for the fishermen, who work in the fishery, not only to go out to fish, but also to help grow and clean up the seaweed grown in the fishery. The only thing to pay attention to is to pay attention to the density and distance of delivery.

The fishermen are busy working, while others put on their diving equipment and go to the bottom of the sea.

Qi Zheng also went into the water.

In the silence of the sea, he could only hear the gurgling sound of strings of bubbles coming out of the oxygen cylinder as he exhaled, and his vision range was only a few meters.

Everyone who goes deep into the bottom of the sea feels small and lonely, and at the same time "plantes" corals the size of a palm on the artificial reef, eager to grow a coral reef.

Yes, the release of artificial reefs is only the first step, in order to rebuild the marine ecology, Qi Zheng also spent a lot of effort to artificially create coral reefs in this sea area!

Coral reefs, known as "underwater rainforests" or "engines of marine life", cover less than two-thousandths of the seabed, but provide habitat for nearly 30% of marine species.

Even the tough sharks and groupers grow from young individuals, and they need a place to grow and hide from predators, and coral reefs do just that. This makes coral reefs one of the most diverse ecosystems on the planet.

However, global warming and human sabotage have led to severe degradation of coral reefs in many parts of the world.

For many diving enthusiasts, they may have noticed the bleaching of coral reefs.

Scientists have predicted that coral reefs will disappear from the earth within 50 years, triggering the collapse of entire marine ecosystems.

It's alarmist or not, but more and more people are paying attention to and protecting coral reefs, and rebuilding them on the bottom of the sea, as Qi Zheng did.

The main body of the reef is made up of coelenterate polyps.

Polyps are interdependent with the symbiotic zooxanthellae, which rely on zooxanthellae photosynthesis for nutrition, and corals have color because of their presence. If the environment is not comfortable and the zooxanthellae leaves, the polyps turn white and then slowly die.

In fact, Qi Zheng's current coral "planting" process is somewhat similar to afforestation on land: seedlings are first cultivated, grown into small trees in the nursery, and then transplanted to the place where they are to be planted. Choose to plant some fast-growing varieties first, and then breed more tolerant varieties.

The "seedlings" of coral reefs are the polyps, which can reproduce asexually and sexually.

Taking advantage of this characteristic, Jiagu Laboratory and Jiangnan Provincial Institute of Oceanography have carried out research on more than 10 kinds of corals for sexual reproduction, and mastered the coral propagation technology from coral fertilized eggs to coral larvae under artificial control conditions.

Then, the coral is further cut into finger-sized broken branches, and its vegetative reproduction is used to artificially cultivate it to form a palm-sized "coral tree".

Finally, it is now attached to an artificial reef in a predetermined area.

If the dream comes true, the seabed will be a sea of purple and red, with a wide variety of marine life shuttling through it. It was absolutely shocking and exciting.

Of course, it is more difficult to "plant" corals on the seabed than to reforestation on land.

The living conditions of polyps are very harsh, the water temperature should not be too high or too low, and most importantly, there must be a clean environment!

On the other hand, underwater operations are heavy and costly. On the basis of coral planting and survival, the department should also find ways to reduce the cost of manpower and material resources.

Qi Zheng, who experienced the difficulty of coral cultivation, surfaced, boarded the boat, and watched the employees who continued to dive to the bottom of the sea and surface, and released his senses.

"Green Bamboo Hundred Array (Third Order) trigger, main wood system, range: 250 kilometers radius. Effect: Moisturizes, grows. The creature is in the array, as if it was newborn, raising purple flowers, and growing vigorously. ”

"Three-star Spirit Gathering Array (third-order) trigger, five series balanced, range: 250 kilometers around. Effect: Gathers spirits and dissolves turbidity. Creatures are in the array, which can make the aura cleanse the body, the soul is solid, and the yin and yang are supple. ”

Without three thirds, how dare you go to Liangshan?

Coral reefs grow slowly, with even the fastest staghorn corals only growing about 10 centimeters a year, and some species less than a centimeter a year. Under normal circumstances, it would take decades or even hundreds of years to grow a large area of coral reefs.

He doesn't need to wait decades.

The "Green Bamboo Lark Array" provided them with a health opportunity, and the corals on the bottom of the sea began to multiply frantically, although they were not visible to the naked eye, but they were silently spreading. At this rate of growth, it only takes a few years for the coral reefs on the seabed to be considerable.

In addition, there is the "three-star spirit gathering array" to nourish the body, which greatly enhances the tolerance of corals, and the survival rate can be close to 100%, not to mention, even if there is bacterial invasion and temperature rise, there will be no degradation.

Qi Zheng exhaled lightly, wishing that there were reefs on the bottom of the sea, fish in the water, and the blue sea under the blue sky would last forever.

To achieve this goal, it is not only necessary to "plant" corals, but also to nurture seaweeds, seagrasses, shellfish and other organisms throughout the ecosystem, so that the marine biodiversity is increasingly rich and vibrant.
