Carp is a tropical fish, individual large, less prickly flesh, taste like river raft, so there is "eight mustache," said, and has a fast growing, broad food, less disease and other good traits, is a freshwater fish Excellent varieties. However, its disadvantage is poor cold resistance. When the water temperature falls below 7°C, it is easily frozen to death. Therefore, the growth period is very short. It is only 5-6 months in the whole year. Since it is impossible to spend winter in natural waters (except for Guangdong and Guangxi Provinces), the market for fresh fish is highly concentrated during the high season of fishing season, causing a backlog of fishery products, which has a low price and low efficiency. In addition, the killing of squid during the breeding process is serious, which greatly affects the increase of stocking density and yield. However, if you use some production tips and use scientific methods to farm squid, you will get twice the result with half the effort.
Two-level fry just arrived from the fry, the resistance is weak, and the specifications are different; if directly into the pond feeding, because of the large range of fry activity, physical exertion, and the input of the bait is difficult to eat for a while, resulting in Waste, but also pollute the water. However, if two-stage seedlings are put in place, they are first intensively reared in small ponds and then put into the pond for feeding. This will not only make it easier to manage, but also allow fish fry to better adapt to the new environment, and easily get enough food in small ponds to promote its rapid growth. When the fry raised in Xiaotang reaches about 10-15 cm, large species of fish can be selected from the pond and put into the pond for breeding. Small species of fish remain in small ponds for intensive cultivation to balance the growth of fish species. Consistent. This avoids the phenomenon of large fish eating small fish in the breeding process, thereby effectively increasing the survival rate and unit yield of the fry.
Rational feeding materials The squid is an omnivorous fish and has bulimia. Therefore, it is necessary to correctly control the amount of feeding, so that the number of fish thrown in the pond can be prevented from feeding blindly. At the same time, it is necessary to implement sub-point feeding, even bait, small meals, enough to feed enough to prevent inequality, and there is polarization. At the same time, in the initial stage of fry cultivation, animal feeds should be used as the main, and intensive cultivation should be carried out. With the growth of fish, some plant-based feeds can be gradually transferred to combine animal and plant feeds. The daily feeding amount should be controlled at about 5% to 8% of the total weight of the fish body, and the feeding amount should be adjusted every other week or half a month to make the amount of feeding more reasonable.
The practice of catching and rearing is due to the fierce gluttony of the carp. When feeding, the big fish often catch food first, and the small fish cannot eat food, resulting in an increasing gap between the size of the fish. Therefore, a round should be taken before catching the carp. Gradually divide the fish and raise the size of the fish to keep the balance of growth. This is one of the important measures to increase production.
In order to promote the wintering and fall fishing of squid, in addition to the sale of big fish, some of the adult fish can be moved into deep pools over winter (nylon ponds on the pond) and sell early spring fish; this can solve the problem of difficult sales of squid during the high season and extend the freshness Fish supply time, and the fish price can be doubled, really kill two birds with one stone.
Bladder Catheters are often used in postoperative patient treatment or a balloon catheter can also be used in a care facility for micturition disturbances. It often comes into use in postoperative care in hospitals, urology practices and care facilities.
