How do you know if there are any fish underwater by looking at the water surface?

As the saying goes, there are no big fish in clear water, and there are fish in muddy water to hide;

2. Watch aquatic plant fish

See if the aquatic plants are lush. If the aquatic plants are lush, it means that there are few skineaters. Looking at the traces of aquatic plants, if the aquatic plants are incomplete and the stems are floating, it means that there are many herbivorous fish. According to the depth of the aquatic plants eaten, the size of herbivorous fish can be judged, and nothing is long, indicating that there are many fish;

3. Watch the fish with waterline

The water waves are sparkling, the water surface ripples from time to time, some fish splash, or chase and play, and sometimes jump out of the water, indicating that there are many fish underwater; Small fish swimming and frolicking on the water suddenly get scared and flee everywhere, or there are faint ripples on the water surface, which are mostly caused by big fish foraging; If there are fish floating on the water and chewing water, it means that the water is anoxic and the fish will not eat;

4. soak and watch the fish.

Bubble is an important symbol reflecting the floating direction, species, quantity, size and density of fish. By watching the fish in the bubble, anglers can get underwater information.

Step 5 watch waterfowl

When anglers come to lakes and rivers, if they see water ducks and egrets perched on the edge of aquatic plants suddenly take off, or see egrets hovering over the water, cormorants and water ducks splash on the water, it means that the fish here are more active and suitable for fishing with hooks;

6. See if there are any small fish activities on the shore.

If there are small fish swimming on the shore, there are other fish in the water;

7. Listen to the sound of water

The sound of knocking accompanied by the sound of fish jumping can judge the situation of fish. Listen to the "scraping" sound of fish eating grass and the "plop" sound of big fish chasing small fish. There are fish when there is sound, and there are few or no fish when there is no sound;

8. Observe fish through the taste of water

Before fishing, stand upwind or squat on the shore to smell the wind blowing from the water, or hold water to smell the fishy smell. The stronger the fishy smell, the more foam formed by mucus secretion left by fish schools, and the less fish there are.
