Today, explain the three factors that affect the fishing port at sea.

First, the tide. Fish come with the tide, fish go with the tide, a tide, a tide of fish. Fishing friends who often go fishing in the sea know that the tide has a great influence on the fishing mouth. The fish mouth is often good after the high tide, and it is often poor after the low tide. In fact, fish don't necessarily drift with the tide, just because the tide can bring enough food and oxygen to make marine fish active and then take the initiative to feed. However, there are also dead tides, and the water level has not changed significantly. The seawater cannot circulate with the ocean and will not improve the fish mouth.

Second, the wind. The bigger the storm, the more expensive the fish, and the windy weather is good for fishing. Although the ocean is very big, marine fish will be deprived of oxygen, especially in calm sea, and the fish mouth is often poor, so it is difficult to catch marine fish. In stormy weather, fish mouths are often surprisingly good, mainly because strong winds can increase the dissolved oxygen content in seawater, make marine fish active, and then open their mouths to eat crazily. So the bigger the storm, the easier it is to fish, which has scientific basis.

Third, at present. Ocean current, also known as ocean current, refers to the large-scale flow of seawater in a certain direction. The distribution of ocean current is mainly influenced by prevailing wind, uneven density of seawater, earth deflection, seabed topography, coastal contour and islands. According to the causes, it can be divided into wind current, density current, gradient current, inclined current and compensation current. According to whether the water temperature is lower or higher than the water temperature passing through the sea area, it can be divided into warm current and cold current. The direction of water flow is not necessarily the same as the wind direction, and sometimes even the opposite. Generally speaking, the bigger the current, the better the fish mouth, and the worse the current, but not absolutely.
