The living rules of fish are not only affected by the factors of the natural environment, but also by many factors such as temperature, season, wind direction, air pressure, water quality, etc.; the following fisherman Xiaobian will analyze the living rules of freshwater fish in different waters for you.
(a) Which areas of water the fish live in
Only by understanding the living environment of the fish can fishing be targeted and reduce blindness.
Where do fish live in the water? We divide the water surface into three levels: the bottom, the middle and the upper layer. Fish live on different levels of water for physiological reasons.
The most fish live on the bottom of the water: such as crucian carp, carp, catfish, bream, bluefish and so on. Their food sources are mainly small mollusks in the bottom of the water, detritus of insects and plants, leafy grass, etc. They also sometimes swim to the middle layer of the water, mainly because of temperature changes. On a sunny day, the middle and upper layers of the water are warmer than the bottom of the water due to the irradiation of the sun, and the fish will naturally swim to the middle and upper layers of the water. At the same time, fish will often swim to places with aquatic plants and branches due to spawning reasons, and they will be found at these fishing spots.
The fish living in the upper layer of the water are silver carp, bighead carp, grass carp, etc., and the cockpit sometimes lives in the middle waters, especially silver carp and bighead carp, which basically do not reach the bottom of the water.
Small white minnow and silver carp mainly live in the upper layers of the water, because their food sources are mainly plankton floating on the water, algae plants and seeds, fruits, and insects that are blown into the water by the wind from trees and crops near the water.
Fish also don't absolutely live in a certain layer of water, it changes with the seasons.
These situations are important for anglers. What fish to catch in what season, you should consider which water layer the fish will live in at that time.
Name of fish Aquifer fish name Aquifer crucian carp under catfish under grass carp, middle white stripe on the upper bluefish under blackfish, middle, upper silver carp in the middle, upper bream in the upper bream, lower carp under the turtle under the yellow jaw
Common conditions of freshwater fish living in the water layer
(2) Whether the fish has a nest or not
Do fish have fixed nests? Anglers want to be able to throw bait into the nest during fishing, and if they can, there will be a surprise harvest.
To be precise, most fish do not have fixed nests. In winter, fish will lie still in the mud in the potholes under the water to avoid the cold. When the spring blossoms, the fish will swim away, "where suitable is home", this fit includes the following conditions: First, the temperature is suitable. In the spring, the temperature rises, the water temperature in the shallow water area rises quickly, and the fish go to the shallow water area to "settle down". In the summer, when the water temperature is high, the fish swim to the deep water area where the water temperature is relatively low: the second is the dissolved oxygen of the water. Due to water temperature and other reasons, the amount of dissolved oxygen in water will also change, and fish will look for waters with relatively large dissolved oxygen: the third is aquatic plantation. Aquatic plants are closely related to the life of fish, and places with aquatic plants are often the home of fish, such as grass carp that especially like aquatic grass, and where there is grass, it becomes the "nest" of grass carp. In the same water, if one side is close to the road, people come and go, not quiet, fish naturally avoid the distance, will go to the quieter waters to live. Some of the piers, culverts are close, and livestock and poultry often go into the water, which is also an area where fish like to inhabit.
Due to changes in water temperature, weather, and water volume, fish "nests" change, such as reservoirs and lakes, fish often inhabit waters close to crop fields on the shore, because these places are their food sources.
