The tides are produced by the moon and the sun’s gravitational force. Under the influence of gravity, the moon is attractive to the seawater on the earth. People are called the tidal force to attract the tide of the sea. The surface of the earth is not far from the moon. The same, therefore, the tidal force of the seawater varies from place to place. Generally, the tidal force is large against the moon, and the tidal force of the sea against the moon becomes smaller, the centrifugal force becomes larger, and the seawater is in centrifugal force. Under the influence of the face, running to the side of the moon, there will also be a high tide.
As the celestial bodies are moving, the tidal forces in the seawater are constantly changing, causing the seawater on the earth to rise and fall, thus forming a tidal phenomenon. Not only is the ocean affected by the moon, but the water of the large reservoir will also be affected by the moon during the day, with a water level difference of 2 to 5 cm. The water flow direction of the lake reservoir not only flows from the tail of the reservoir to the dam head, but also counterclockwise or clockwise flow under the action of lunar gravity and the rotation of the earth.
On the first line of the lunar calendar, the earth, the moon and the sun are on the same line. The gravitational force of the moon and the sun on the earth is superimposed, and the tidal force is relatively large, so that the seawater rises the highest and falls to the lowest, forming a tide. On the seventh, eighth, twenty-second, and twenty-threeth of each month, the gravitational pull of the moon and the sun is just the opposite. The tidal force is reduced, so that the fluctuation of the seawater is not large, and there is a small tide. However, due to the influence of various resistances when the seawater flows, the occurrence of large and small tides lags behind for two days. That is, there is a big tide in the second, third, seventh, and eighteenth of each month; and there is a small tide in the first nine, the tenth, twenty-four, and twenty-five.
As the saying goes: Fishing people do not understand the tide, it is equal to hustle and bustle, go fishing when the tide is high, and go home to sleep when the tide is low. It is a good time for fishing during the high tide and low tide.
Scientists have long observed and studied the fish habits and reproductive functions of fish in the rivers and lakes, which are directly dominated by the moon clock. For example, the fish in the ocean forages follow the ebb and flow, and the fish foraging in rivers and lakes follows the law of rising and falling. At the seaside, fish often complete the spawning and reproduction of the offspring before and after the full moon.
The effects of the moon and tides on fish are mainly as follows:
[1] The gravitational force of the moon affects the biological clock of the fish, making its biological behavior appear adaptive.
[2] The moon not only causes ocean tide changes and ocean current movement, but also promotes the movement of the lake reservoir water flow, promotes the exchange rate of upper and lower water flows, increases the dissolved oxygen in the water, and makes the fish foraging activities flourish.
[3] The moon affects the activities of various creatures at the same time, various biological activities appear regular, not only the fish want to eat, but also eat.
Taking into account the changes in seasons, water temperature and air pressure, combined with the law of the moon’s profit and loss, when various factors are favorable, the best fishing time can be determined:
[1] From the first quarter to the full moon (the moon is in the middle of the night), the brightness of the moonlight gradually increases. The fish activity is frequent in the first half of the night, and the feeding is active. In the latter half of the night, the moonlight is dim, the fish activity is reduced, and the morning is active again.
[2] Full moon to the next string month (the moon is empty in the midnight and the second half of the night), the brightness of the moonlight gradually weakened, fish activities are still active, but concentrated in the latter half of the night, activities in the morning decreased, intermittent rest.
[3] The first day of the lunar calendar to the fifth day of the lunar calendar or the lunar calendar 16 to 20, the sun, the moon, the earth is basically three points and one line, for the tide, the person is called “big live”, the fish go out foraging, fishing There will be good gains;
[4] The first six to twelve lunar calendar or the lunar calendar twenty-one to the lunar calendar twenty-five is a small tide, known as “dead sputum”, of which the first nine or twenty-four is the minimum tide, known as “dead bottom”, not suitable for fishing.
[5] The first one, fifteen, the moon tidal maximum, also known as the Meridian tide, should be fishing at noon.
