If you want to catch a fish well, it is important to try your best to understand the behavior of the fish. Water temperature, dissolved oxygen, food distribution and security are the basic elements and core factors for understanding fish behavior. As a temperature-changing animal, the body temperature of fish is very close to the external water temperature, which largely determines the body temperature of fish, thus having obvious thermotaxis. 15-25 degrees is the most acceptable water temperature for fish such as crucian carp, grass, bream and so on, which we often catch. The bait is the most active, especially over 20 degrees. For example, “fishing for beaches in spring, fishing for pools in summer, fishing for shade in autumn and fishing for sunshine in winter” is actually looking for fish according to temperature.
In a strange water area, Most of us infer the general topography of the underwater according to the topographic characteristics of the surrounding banks. According to the topography of the upper and lower reaches and the shore, we may be able to judge the relative depth of the water so as to determine the fishing position. In many cases, we may be able to do the right thing. However, due to the invisible situation at the bottom of the water, it is easy to make mistakes. For example, some places at the bottom of the water have ditches and ridges, and some places have submerged grasslands and tree stumps, which we cannot see by our eyes. Fish are animals with group behavior. The fish that may be caught in one place are too large, while the fish that may be caught in the other place are too small. If there are already fishermen fishing, they can not rush down the pole, look at the depth of their fishing points and the situation of fishing, and ask them more about the recent situation of fishing in various places, so as to get a general overall judgment on the situation of the waters.
Pay attention to on-site observation. Areas with aquatic plants, reeds, lotus flowers, submerged crops and other plants should be given priority. Traces of human activities, such as fruit trees and fields planted on the shore, sundries thrown in the water, places where vegetables and rice are washed, and places where chickens and pigs are fed, are also places that we cannot easily let go of. Signs of fish activity, differences in water color, fish stars and fish waves are also clues for us to find fish. Pull out a longer pole, install a float, add a heavy drop, and measure the depth everywhere nearby, front, back, left and right, so as to judge the underwater slope priority, flatness and groove position, thus determining which fishing point is better.
Different fishing methods have different characteristics and application scope, and there are differences in the selection of fishing positions and fishing points according to fishing methods. When a shoal is not suitable for hand fishing, it may be the best place to use the sea pole. When a piece of deep water is not suitable for fishing in the distance, it may be just suitable for fishing near the shore. The grass hole in the middle with dense aquatic plants and the near root of reed and cattail grass can be caught very well with long pole and short line seven stars floating. However, if you change to Taiwan fishing, you will break the line and lose the hook, and you will get very little. Instead, it is better to do nest fishing on the outer edge of the grass or in the bright water area beside it.
In the old fishing position, fish always come around. People throw weeds, corn stalks, sweet vines and other things into the water when farming, which will attract fish and bees to stab them. In front of the bait casting machine, where chickens, ducks, pigs and cow dung are abandoned, fish will be like guarding Jinshan. Wind and waves blow debris and microorganisms on the water surface to one shore and one corner, and fish will follow them. There are many microorganisms in aquatic plants, tree stumps, rocks and other places, and there are many small fish and shrimps, so the fish will miss and forget to return. Goukan, Huiwan, mud bottom and gravel bottom naturally deposit a lot of food, and fish will take it as their home. Many situations have provided us with powerful clues in choosing fishing positions.
