Teach you practical skills to identify various fish stars

There are many advantages to learning to identify fish stars. One is to be able to determine what fish are underwater, the second is to select fishing spots based on the location of the fish stars, and the third is to play catch-up fish when the fish conditions are not good in winter or spring. . Is that right? What is a fish star? Let's learn about it together below!

One, fish star and natural blisters

The so-called fish star is a small gas produced by some fish playing in some particular waters to eat or breathe, and bubbles formed when they escape the water surface.

When the fish breathes, they breathe oxygen and exhale carbon dioxide. Carbon dioxide escapes the water surface and forms fish stars. In addition, when the bottom sludge contains biogas, when the sludge is stirred by the fish and the biogas escapes the surface of the water, fish stars will also be formed.

Fish exhaled carbon dioxide to form a fish star, there are additional conditions: First, large and medium-sized fish in the underwater activities; Second, ferocious fish when chasing small fish shrimp. In this case, the fish's respiration is larger and the amount of carbon dioxide emitted is correspondingly higher. However, those individuals with very small fish normally have very little exhaled carbon dioxide. Even if they can form a fish star, their individuals are very small and shaped like millet, which is hard to find with the naked eye.

It should also be noted that in many cases, when the biogas contained in the sludge accumulates to a certain degree, it will automatically escape the water surface. The blisters formed by this naturally occurring gas are obviously different from those of fish stars. The characteristics of the two are summarized as follows:

1, the characteristics of fish star

1 A sudden appearance of a small number of waters emerged after a long time without breaking.

2 one after another. Displacement often occurs and its direction is not fixed.

3 are big and small, sparse and sparse. Fish big fish stars are also large, fish and more fish stars. There are long and short intervals.

4 When there are many fish stars, water quality is often turbid.

5 Stopped by sound interference.

2, the characteristics of natural blisters

1 The individual bubbles are larger and rise above the surface and burst.

2 The position appears unchanged. Almost the same size.

3 intervals appear, long duration.

4 There is no change in sound interference.

Second, the fish star of several common freshwater fish

1. Sturgeon fish star

Carp fish stars are characterized by small intensive and unfixed positions. There may be one or three to five at a time, and sometimes more. Bubbles are basically the same size, and occasionally have different sizes. Big fish have larger fish stars, and small fish have smaller fish stars. Usually 50 grams less than the small carp, the fish is equivalent to the size of mung bean; 100-200 grams of turtle turtle, the fish is roughly equivalent to the size of soybeans, big turtle's fish star up to the size of beans.

2. Sturgeon fish star

Carp fish star individuals are slightly larger than catfish fish stars, and they are numerous and dense, appearing in multiple strings. Bubbles vary in size. Sometimes a lot of crushed bubbles are produced like boiling, which can occur consecutively at 10 in a row. And often accompanied by the phenomenon of movement. The large carp fish star is large and the small carp fish star is also small. When the water is shallow, it is often accompanied by a rise in muddy water, which is caused by the feeding of carp arch mud.

3, grass carp fish star

Grass carp fish stars are larger and larger in number than trout fish stars, but they are smaller than trout fish stars. Usually one or two larger fish stars appear first, followed by smaller fish stars. Bubbles are numerous and dense, sometimes forming a small piece of foam a few square centimeters.

4, carp fish star

Carp fish stars are also small individuals, and Fan Yan is not too big. Fish stars are scattered and not concentrated, but they often appear continuously.

5, herring fish star

Herring fish star is characterized by a few large bubbles, followed by several smaller bubbles. Herring fish stars are sometimes very similar to grass carp fish stars.

6, black fish star

Black fish will spit out some air bubbles while eating. Bubbles are small and dense, rising faster. It is long and disappears faster. Blackfish sometimes spit out 2 or 3 big bubbles.

7. Sturgeon fish star

Carp fish stars are long strips, dense, small and numerous, constantly moving.

8, squid star

The catfish star is similar to the catfish fish star. Uneven size, the big ones such as table tennis are big, the small ones are bigger, and the number is larger.
