What does it mean that your brother doesn't keep any fish but only the catfish that sticks to you?

Catfish, a fish that is active by nature, is not particularly special. However, since fishermen used it as a tool to keep sardines alive during long-distance transportation, the role of catfish has been increasingly valued. Sardines, by nature, like to be quiet and seek stability. They have no clear understanding of the dangers they face, and just want to be comfortable with their current lives. The fisherman cleverly used the catfish's activeness to keep the sardines alive, and in the process, he also gained the greatest benefit.

So, the meaning of this sentence can be understood as I am indispensable for your survival.

Hope you can adopt my suggestion. Thank you, dear.

The difference between Qingjiang fish and catfish_Catfish breeding methods (2)

Catfish breeding method: two-stage frying. The newly transported fry have weak resistance and different sizes. If they are directly placed in a large pond for breeding, the fry will have a large range of activities, consume a lot of physical energy, and it will be difficult for the bait to be eaten at once, resulting in waste and water pollution. However, if two-stage frying is implemented, that is, first concentrated in a small pond for intensive breeding, and then placed in a large pond for breeding, it is not only easy to manage, but also allows the fry to better adapt to the new environment, and it is easy to get sufficient food in the small pond, which promotes its rapid growth.

When the fry in the small pond reaches about 10 to 15 centimeters, the large fish can be selected from the pond and put into the large pond for breeding, while the small fish are still kept in the small pond for intensive breeding, so that the fish grow in a balanced way and have the same size. This avoids the phenomenon of big fish eating small fish during the breeding process, thereby effectively improving the survival rate and unit yield of the fry.

Feed the bait reasonably. Catfish is an omnivorous fish with voracious nature. Therefore, the feeding amount should be correctly controlled, and the amount of feed should be fed according to the number of fish in the pond to prevent blind feeding. At the same time, it is necessary to implement point feeding, spread the bait evenly, feed a small amount of food multiple times, feed enough to prevent hunger and satiety, and polarization. At the same time, in the early stage of fry cultivation, animal feed should be used as the main feed for intensive cultivation. As the fish grows, some plant feed should be gradually switched to combine animal and plant feed. The daily feeding amount should be controlled at about 5-8% of the total weight of the fish body. The feeding amount should be adjusted once every week or half a month to make the feeding amount more reasonable.

Carry out rotational catching and separate breeding. Because catfish are fierce and greedy, when feeding, the big fish often grab the food first, and the small fish cannot get the food, resulting in a larger and larger difference in fish size. Therefore, before catching catfish, a rotational catching and separate breeding should be carried out, and the big and small fish should be raised in different ponds to achieve a balanced growth. This is one of the important measures to increase production.

It is recommended to overwinter catfish. When fishing in autumn, in addition to selling large fish, some adult fish can be moved into deep water ponds for overwintering (build nylon sheds on the ponds) and sell early spring fish; this can not only solve the problem of difficult catfish sales in the peak season, but also extend the supply time of fresh fish, and the fish price can be doubled, which is really killing two birds with one stone.

Catfish breeding precautions

Catfish is an excellent species of freshwater fish, but its disadvantage is that it has poor cold resistance and is easily frozen to death when the water temperature drops below 7℃. Pay attention to keeping warm in winter.

Catfish are ferocious and greedy. When feeding, big fish often grab the food first, and small fish are easily starved of food. Pay attention to raising big and small fish separately.

How to distinguish Qingjiang fish from catfish

Catfish have a rounded, fan-shaped tail, whereas trevally have a forked tail.

The catfish has a relatively large head and is flat in shape.

The t-fish has no scales, and the back edge of the spines on the dorsal and pectoral fins is serrated. The catfish has a very small dorsal fin, no spines, and 4 to 6 fin rays.

Catfish generally have only one dorsal fin on their back, while tuna have two dorsal fins on their back, one at the tail and the other at the front of the body.
