The reason why fish don't eat

Water quality problem

Water is the environment in which fish live. Water quality will change due to the influence of external natural conditions and man-made factors. If there is a flood, the color of the water becomes muddy and there is much sediment in the water, which is not conducive to the life of fish; too many aquatic plants, or decay and deterioration, will also affect the water quality. Especially under the influence of people, if people dump a large amount of domestic sewage into rivers, lakes and levees, the water quality will become worse; the waste water from factories contains chemical and toxic substances that flow into natural waters, and fish are seriously threatened, not only have no appetite, but also lose their lives. Therefore, the quality of water quality is the main factor affecting the eating habits and appetite of fish.

Water temperature problem

The best water temperature for temperate fish is 15 C-25 C. in this temperature range, fish are active and have a strong appetite. If the water temperature is lower than 10 ℃ or higher than 350 C, the fish will feel uncomfortable, have less activity, have a low appetite, and even do not eat. The weather of nature is rapidly changing, with clear skies for thousands of miles, dark clouds pressing the top, lightning and thunder, strong winds, waves in the water and turbid mud, which changes the living environment of fish and brings about physiological changes accordingly. If the dry and hot temperature drops, breeze and drizzle, the amount of dissolved oxygen in the water increases, the fish will become active from dull to active, and the appetite will be increased. At this time, the effect of fishing will be good.
