Tian Lingshuang overheard the conversation, and couldn't help but chuckle in her heart, and said in her heart, no wonder the fishing boat was sneaky yesterday, it is July now, and it is the fishing ban period, obviously this fishing boat owner has his own sales channels. Is it okay to meet a kind person like a shopkeeper's wife, but if someone is unhappy, he can't report himself? Just explaining will have to wear out his mouth, and what money will he make?

Besides, there are really few fish in this sea, not at all like the schools of fish everywhere you see in movies and television. She also understands that maybe the fish in the offshore waters are almost caught. You can go to the deep sea, and the conditions do not allow it. Besides, just for the sake of the money to buy the ticket in front of her, would she take the risk when she didn't know anything about the ocean?

Tian Lingshuang surrounded the fishing boat, avoided the fishing nets, and swam a few times, but did not see any fish. Downstream, although she couldn't feel the pressure of the water, and her eyes could see in the dark of the water as if they had been refining in the alchemy furnace, but there were no creatures around, what should she do if she was suddenly a little scared in her heart?

Just as she was deflated and wanted to swim upstream, she noticed that some small sea fish of an inch long began to swim around her. It turned out that she was about to swim to the bottom of the sea. Moreover, to her surprise, she saw a small piece of coral reef, saying that it was a small piece, because this coral reef was really not large, Tian Lingshuang swam around it, and it was estimated that it was the size of a basketball court. Although the area is small, it does not detract from its beauty.

If you haven't seen real coral, you won't know how beautiful coral is! Tian Lingshuang's eyes lit up. The corals here look like antlers, some like branches, some like chrysanthemums, some like a bunch of small pipes, some like fans, some like mushrooms, and some like fireworks. Colorful, red, white, green, yellow, beautiful. Occasionally, small sparkling sea fish swim past the coral, adding to the beauty. There are also some oysters, mussels and various scallops hanging on the reef.

Tian Lingshuang is not ignorant of coral reefs, and knows a little. In the past, because she was fascinated by the beauty of coral reefs, Tian Lingshuang watched a marine program dedicated to the protection of coral reefs. Tian Lingshuang couldn't remember the others, but some she still hadn't forgotten: coral reefs were formed by the bones of polyps made up of calcium carbonate over hundreds to thousands of years. Each polyp is the size of a grain of rice, and they live in groups of co-packs, metabolizing, growing and multiplying from generation to generation, while secreting limestone and bonding it together. These limestones are then compacted and petrified to form islands and reefs, also known as coral reefs. It is present in both deep and shallow seas. Coral reefs provide habitat for many species of flora and fauna, including worms, mollusks, and organisms such as oysters, mussels, and shells.

However, with global warming, the melting of the ice sheets in the Arctic and Antarctic has affected the normal life of many polar organisms, and in slightly warmer places, the ecological balance of the oceans is also out of balance before the terrestrial life is greatly affected. Large tracts of coral reefs in some nautical miles are beginning to shrink and disappear. Coral reefs and other marine life form a complex underwater ecosystem, including oysters, mussels and shells.

Oysters filter and purify seawater every day, and they inhibit algae overgrowth by ingesting phytoplankton and other particles, then release clean water and nutrient-rich particles for other marine life to eat. It is said that an oyster can filter and purify 200 liters of seawater per day -

However, for Tian Lingshuang, these are not important, the important thing is that whether it is oysters, mussels, or shells, there may be pearls in them! This is simply great, isn't it? If she finds a few round big pearls from these pearl oysters, won't she suddenly become a rich woman? Well, she may not be so lucky, then even if there are no big pearls, a few small pearls can be sold for a thousand yuan, not to mention buying a ticket, you can also buy some seaside specialties for her mother, brother and good friend Wang Xue to take back.

Thinking of this, Tian Lingshuang was like being beaten with chicken blood, and her fighting spirit was instantly high. Avoiding small sea fish, kelp, and seaweed, Tian Lingshuang stuffed the oysters, mussels, and large shells she saw into the woven bag in one go, and the two woven bags were full, so she regretted that she had packed too much. Fortunately, she saw that there were many more on the reef, so she settled down.

When she was swimming upstream, she found a small group of crabs, I don't know what species, she was worried about being clawed by the crabs, so she watched the crabs swim over. Putting his head out of the sea, the fishing boat is still not far away. She had already seen it just now, there were only a few fish and crabs in the fishing nets, and it was estimated that the boatman would cry for such a pitiful harvest.
