7. Fish farming technology?

1.

Stocking time selection: Fish should be released on sunny days when the temperature is not too low. Generally, the temperature should be between 2℃ and 5℃. At this stage, the fish scales are tight and the activity is small. It is not easy to injure the fish during fishing, transportation and stocking operations, which can reduce the morbidity and mortality of fish. It is easy to frostbite the fish on rainy days with low temperature or snowy, frozen and windy weather; when the temperature is too high, the fish scales are loose and the activity is large, which is easy to injure the fish during operation.

2.

Stocking of fish: Before stocking the fish, check whether the drugs have lost their effectiveness after pond cleaning. In early spring, the water temperature is low and the toxicity disappears slowly. Water should be taken in advance and test fish should be released. According to the stocking plan, individual size, density, and matching species and specifications, the fish that can be released at one time should not be released in batches, so that the fish can adapt to the environment, start eating early, and promote growth. At the same time, [Gold Iodine] should be used for drug disinfection when stocking fish.

3.

Feeding at the right time When the water temperature rises to 810℃, fish begin to eat, and the amount of food intake gradually increases with the increase of water temperature, so they should be fed in time. Feed once a day or every other day, and choose to feed at noon on a sunny day; as the water temperature continues to rise, the number of feedings can be increased to twice, that is, feeding once in the morning and once in the afternoon. Feeding should adhere to the principle of four determinations (timing, quality, positioning, and quantity), and the specific daily feeding amount should be flexibly controlled according to the weather, water temperature, and the feeding situation of fish. For grass carp weighing more than 1 jin, it is recommended to feed Da Beinong high-grade expanded feed 8103 in the early stage of feeding; for small grass carp mode, it is recommended to feed Da Beinong microecological juvenile fish special feed [Intestinal Liver Health], and the feeding rate is controlled at about 0.5%1%. This product is rich in nutrients and probiotics, which can quickly repair the fish intestines, restore the physique, and improve immunity.

Grass carp, an animal of the genus Grass Carp in the family Cyprinidae of the order Cypriniformes, is included in the "List of Key Protected Economic Aquatic Animal and Plant Resources of China (First Batch)".

It has an elongated body, with a cylindrical front, a flat tail, a round abdomen, and no abdominal ridges. It has a wide, medium-sized head, a slightly flat front, a short and blunt snout, and a snout slightly longer than the eye diameter. Its scales are medium-sized and round, with an arc-shaped lateral line in the front and a straight line in the back, extending to the base of the tail fin. It is a herbivorous fish that lives in rivers and lakes in plain areas. This type of animal is distributed in China, Russia, Bulgaria and other countries.

10. China’s freshwater predatory fish?

1 sea bass

Perch are usually found at the mouths of freshwater rivers. Occasionally they also forage in freshwater areas. In addition, we sometimes see them in reservoirs. However, they are rare and hard to come by. Perch are ferocious carnivorous fish with a big appetite and a strong desire to feed. They can eat 5%-12% of their body weight, especially in spring and summer. Perch grows quickly and can reach more than one meter in length.

2 Mandarin fish

Mandarin fish usually live at the bottom of the water surface. This kind of fish is very common and is distributed in most waters in China. They like to lie in still water or slow-flowing rivers and lakes, especially in shallow lakes with aquatic plants. This kind of fish has high requirements for the surrounding environment and is more sensitive. During the day, they will lie motionless at the bottom of the water and come out to look for food at night, so this kind of fish is suitable for night fishing. Mandarin fish like to make nests and live alone. When the water temperature is 15-30 degrees Celsius, its activity is still very high. When the water temperature is lower than 7 degrees Celsius, it will no longer be active. It is a typical carnivorous fish because they can prey on the fry of other fish as soon as they hatch. They like to stay in places covered by aquatic plants or blocked by rocks. Anglers can pay more attention to these places when fishing.

3. Upturned lips

The black carp is also a common fish, also known as whitefish or big whitefish. It often feeds in the middle and upper layers of flowing water or wide water areas. This fish is fast and good at jumping. It is more common in rivers and reservoirs and usually feeds on small fish. The largest one I have seen is 10 kg. The sexual maturity age of the black carp is 3 years for females and 2 years for males. The most active period is from June to August. They are used to chasing moths on the water surface. The desire to eat is strongest at night and early morning, so you can choose night fishing.

4. Blackfish

Blackfish is also known as mullet and money fish. It is distributed in all waters except the western region of my country. It is also a target fish that lure fishing prefers. Blackfish generally feed on other fish species, and young blackfish prey on some plankton. After the blackfish bites the hook again, it will burst out with amazing power, and the blackfish is the most aggressive. Generally, it will bite the hook when it sees food. The peak season for blackfish foraging is spring and autumn, and April to July is the spawning season. They will spawn in shallows with lush aquatic plants, and then male and female fish will guard their nests together. Of course, it is not recommended for everyone to go fishing for blackfish at this time. After all, we are "fishing for fishing, not for fish". It is still a bit cruel to spawn and fish for blackfish.
