After getting up early the next morning, Qin Shiou, who was about to go to exercise, knew why the fishermen had discussed so happily last night.

Normally, during a month, at the New Moon or Full Moon, the Sun and Moon exert gravitational pull in the same direction or in opposite directions, resulting in a high tide; But in the first or second quarter, the gravitational effect of the moon opposes the gravitational effect of the sun, and the main ebb and tide are low, and each cycle is about half a month.

From the perspective of a year, there are also two highs and lows.

During the spring and autumn equinoxes, if the Earth, the Moon and the Sun are almost on the same plane, the tidal attraction is greater than that of the other months, resulting in two high tides in spring and autumn in the year.

At other times, the tide is not very big, and you can't even feel it normally.

But there are exceptions to everything, and the size of the tides also has a lot to do with the distance of the moon and the sun from the earth.

As we all know, the orbit of the moon is an ellipse, about once a month or so, close to the earth and far away from the earth, the near-earth tide is 39% larger than the far-earth tide, when the near-earth tide coincides with the high tide, the tidal range is particularly large, if the far-earth tide coincides with the low tide, the tidal range is particularly small.

Similarly, the Earth's orbit around the Sun is also elliptical, with a high gravitational pull and strong tides at perihelion, and a low gravitational force and weak tides at aphelion.

To put it simply, if the position of the earth appears at the nearest point of the moon's orbit on a certain day, and the position happens to be close to the sun, that is, when the sun, the moon, and the earth are almost in a straight line, the sea will receive the greatest gravitational force on that day, and the most powerful tide will be revealed.

This time the huge tides. It starts today.

The tide began to ebb in the early hours of the morning, and when Qin Shiou ran to the beach in the morning, he saw that the sea water had withdrawn far away. Thick, solid stone pillars under the high-pile pier were exposed.

The water receded, revealing what was once the bottom of the sea.

The fishing grounds are full of jagged reefs, covered with seaweed, seaweed, aquatic weeds that have not left with the tide, and there are many fish, shrimp and crabs on the beach.

Large reddish-brown reefs appear on the beach, and they have not seen the light of day for a long time. The seabed of Daqin Fishery has a good texture and is all sand. Qin Shiou can run over in sneakers and take away a reef. A few small crabs appeared below.

Next to the reef, four or five smelt were bouncing with difficulty, not yet dead, struggling to survive on the seaweed attached to them.

Except for courgette. There were also silver herrings around, and the tiger picked up one and shook its head, and Bush Jr. flew down, and he raised his head to shake the fish up, and Bush Jr. took a precise probe and bit the fish into his mouth.

The bear yawned and ran over, and when he saw so many fish on the beach, he was immediately overjoyed, especially the salmon that did not return to the sea in time with the tide and stayed on the beach, which is the supreme delicacy in the eyes of the brown bear.

Qin Shiou accompanied the little ones to play here. Winnie called him for breakfast, and when he went back, Shirley and the others jumped downstairs, wearing slippers and the like. Ready to go pick up fish and scallops.

Duoduo followed behind Shirley like a little tail, her little hands tightly grasped Shirley's skirt, Qin Shiou waved hello to her, she showed a sweet smile and nodded vigorously at him.

Qin Shiou handed the small cup of milk juice to Duoduo, and Duoduo pecked him on the hand. She can't speak, and can only express her feelings with her movements. And sign language is not understood by ordinary people, and she uses kissing movements to the people she likes.

Winnie carried Blossom to the stool, and a few little yellow squirrels rolled in like furballs, looking for the skin of the fruit. Duoduo looked at them curiously, and the little yellow squirrels raised their heads and stared at Duoduo curiously with their dark round eyes.

Winnie divides an apple into five portions and gives it to the little yellow squirrel brothers, who continue to look at the flowers while holding the apple and eating it, their mouths propped up and squirming quickly and looking cute.

"I forgot to introduce the little yellow squirrel family to Duoduo." Qin Shiou smiled, he hugged Duoduo down, and Duoduo immediately squatted on the ground and stretched out his hand to try to stroke the little yellow mouse.

The little yellow squirrel did not hide from it, turned his head to look at her, and continued to eat his share of the apple as fast as he could.

Duoduo unfolded the left hand that she had been holding, there were a few blackberries in it, she handed her little hand to the little yellow mouse, the little yellow mouse looked at the blackberry in a daze, and decisively gave her half of an apple to Duoduo, and replaced it with a juicy blackberry.

Mao Weilong and Liu Shuyan also walked down behind, and seeing Duoduo and the little yellow squirrel having fun together, Liu Shuyan nodded and smiled at Qin Shiou: "Thank you for helping take care of Duoduo." ”

Qin Shiou smiled: "What kind of care is this?" The little girl is making friends by herself, come, let's eat, after eating, we can go to the beach to pick some fish. ”

Hearing this, Shirley and Gordon shouted, "Qin, we don't go to school anymore, let's also pick up fish at home, okay?" ”

"Yes, I saw from the window just now that a lot of fish and shrimp in our fishing ground are on the beach, which must be more than the fishing ground in the town." Michelle said.

Qin Shiou patted the table and told them to eat their own things quickly, and said, "It's okay to stay, but you have to take care of Sister Duoduo, understand?" ”

The conditions were quickly reached, and the children finished their breakfast faster than ever before, bouncing and running out.

Duoduo hurriedly drank the juice in his cup, jumped down on the stool and chased after him, ran a few steps and thought about it, and came back to bring the little yellow squirrels.

Qin Shiou shouted, Shirley remembered the condition just now, and hurriedly came back to pull up Duoduo, Duoduo pointed to the little yellow squirrels behind him with a worried face, Shirley called Gordon back and asked him and Powell to bring the little yellow squirrels.

"What are you taking them for?" Gordon asked unhappily.

Shirley frowned, "Do you have itchy ears?" ”

Gordon shrunk his neck and quickly sneered, "But you can bring it." ”

One morning, Xiong Da was running happily on the beach, with a fat face and facial features happily huddled together, with a silver-scaled salmon in its mouth and a half-large Atlantic salmon in its paws.

The children ran to the reef area, and the big fish they picked up first.

The long coastline, the sea water receded at least two or three hundred meters, and on the vacated beach, reefs were everywhere, and stranded fish and shrimp were everywhere.

At this moment, the prosperity of the fishing ground was vividly displayed in the eyes of everyone, and the fishermen who came behind sighed: "It has been more than ten years, and it is the first time I have seen so many fish left at low tide. ”

Shaq drove a pickup truck and pulled some incubators over, and the boxes contained ice cubes, and the valuable big fish collected were put in to be sold later.

A few children came up and dragged an incubator and ran happily into the bottom of the reef, Winnie shouted: "Be careful, don't take off your shoes, there are a lot of broken stones, understand?" ”

The children waved their hands without looking back to indicate that they knew, and whether they listened or not, only God knew. (To be continued) R580
