1. Conditions and requirements for snakehead fish farming, what are the differences between wild snakehead fish and farmed ones?

Breeding conditions: The pond for breeding black carp does not need to be particularly large, about 3 acres to 5 acres is most suitable. The specifications of the fish species must be determined according to the specifications of commercial fish in the market, so 75 grams to 100 grams of black carp can be released for each tail.

Breeding requirements: The water for raising black carp can be river water, underground well water, reservoir water, etc., but no matter which type of water is used, the water source and water quality must be clear and clean.

1. Conditions and requirements for snakehead fish farming

1. Conditions

(1) The pond for breeding snakehead does not need to be too large. About 3 to 5 mu is more suitable. The water depth of the pond must be between 1.5 and 2.0 meters. It is necessary to ensure that the pond has sufficient water and is easy to drain and inject water.

(2) The size of the fish to be released must be determined according to the size of commercial fish on the market. Therefore, the size of the fish to be released is about 75 grams to 100 grams per fish. When releasing the fish, it should be noted that the density must be determined based on factors such as the source of feed and breeding technology.

2. Requirements

(1) The water used to raise snakehead fish can be river water, underground well water, reservoir water, etc. However, it should be noted that no matter which type of water is used, the water source and water quality for raising snakehead fish must be kept clear, and the pH value should preferably be neutral or weakly alkaline.

(2) Some aquatic plants must be planted in the snakehead fish pond. This is because the main function of aquatic plants is to purify water quality and provide a good environment for snakehead fish. They can also provide a place for snakehead fish to hide and protect them from the sun. However, the planting area should not be too large and can generally be controlled at 2% of the fish pond area.

2. What are the differences between wild snakehead fish and farmed ones?

1. Different taste: Artificially farmed black carp has been raised all the time, so its meat is rough and soft, and it tastes like chewing wax; wild black carp often lives in the wild, so its meat is relatively firm and tastes delicious.

2. Different natures: Artificially bred black carp has become very docile due to being raised for a long time; wild black carp is more ferocious and more difficult to catch because it often lives in the wild.

3. Different shapes: Artificially farmed black carp is relatively large, and its body is white or yellow-green; wild black carp is relatively small, mainly because its meat is relatively compact and its body is black.

2. Differences between wild soft-shelled turtles and artificially raised soft-shelled turtles

The texture of meat is different, wild meat is delicate

3. The difference between farmed and wild hairtail

Hairtails need to live in deep sea environments, the breeding cost is very high, and the catch is large, so hairtails are not farmed.

4. How to distinguish wild soft-shelled turtles from farmed soft-shelled turtles

2. From the appearance of the carapace. The carapace of wild turtles is smooth and flat, with thin and even skin, waxy luster, and the outline of the shell can be seen faintly. However, the carapace of domestic turtles is slightly thicker, with rough warts and dull texture, and it is difficult to see the outline of the shell on the toad skin.

2. Look at the color of the carapace. Wild turtles are gray-black, khaki, brown with black spots, etc., while domestic turtles are mostly black with green, yellow with green, green moss, etc.

3. From the perspective of body shape. Wild turtles have been foraging for food in the natural state for a long time, so they are strong, slightly flat, and have firm muscles. However, domestic turtles are bloated, thick and clumsy, and have loose muscles.

4. Press the plastron. The elasticity of the ventral cartilage of wild turtles is relatively high, and the rebound force is large when pressed with fingers. However, the elasticity of the ventral cartilage of domestic turtles is weak, and it feels soft and weak when pressed with fingers.

5. How to distinguish between domesticated soft-shelled turtles and wild soft-shelled turtles

Generally, wild authentic soft-shelled turtles have the following characteristics: 1. They are usually not very big because they grow slowly; 2. The carapace is shiny because they grow for a long time; 3. The body of the soft-shelled turtle is relatively thin and not fat because the soft-shelled turtle does not eat regularly and may eat only occasionally; 4. The nails are generally relatively sharp; 5. The body fat is less than that of farmed soft-shelled turtles, which is related to the lack of food security for soft-shelled turtles.

6. How to distinguish whether the small turtle is wild or domestic

Distinguishing method:

1. The back of farmed turtles is rough and not smooth, and the skirt (also called flying edge, located around the turtle, the most delicious part of the turtle) is thin, while the back of wild turtles is smooth and the skirt is thick;

2. The claws of farmed turtles are neither hard nor sharp, and are whitish in color, while the claws of wild turtles are hard, sharp, and yellow in color.

3. The belly of farmed soft-shelled turtle is white and red and tender, while the belly of wild soft-shelled turtle is black, with clear stripes and dark color.

4. The fat of wild turtle is yellow, feels rich in gelatin and has good viscosity; while the fat of farmed turtle is mostly light white and has poor viscosity.

5. To distinguish the sex of a turtle, you need to look at its genitals. If it is larger and thicker than the hem, it is a male. Otherwise, it is a female. Male turtles are thin and have thick flesh. Female turtles are thick but often have many turtle eggs in their bodies. They may look plump, but once cut open, they appear to be thin and hollow.

When buying soft-shelled turtles, you should also learn to identify sick and disabled soft-shelled turtles and water-injected soft-shelled turtles:

The sick and disabled turtles are skinny, some have rotten bellies, and have difficulty crawling. Some vendors inject water into the turtles to increase their weight so that they can sell them at a higher price. The characteristics of water-injected turtles are: they are soft and not solid to the touch, they look strong but not fierce, they are dull and ineffective when moved, and they will not turn over when pushed.
